Apply the same fixes and improvements as to the gtk-1-3-win32-production
2002-01-10 Tor Lillqvist <tml@iki.fi>
Apply the same fixes and improvements as to the
gtk-1-3-win32-production branch: Bug fixes and cleanup of
selection and DND functionality. Still doesn't work as well as the
win32-production branch, though, but getting closer.
After this, need to add Archaeopteryx Software's OLE2 DND support.
* gdk/win32/gdkselection-win32.c (gdk_selection_owner_set,
gdk_selection_send_notify, generate_selection_notify): Don't use
SendMessage() to generate events for the same app, instead use
gdk_event_put().
* gdk/win32/gdkprivate-win32.h
* gdk/win32/gdkglobals-win32.c
* gdk/win32/gdkmain-win32.c
* gdk/win32/gdkevents-win32.c: Thus, remove declaration, definition,
initialisation and handling of gdk_selection_notify_msg,
gdk_selection_request_msg and gdk_selection_clear_msg.
* gdk/win32/gdkselection-win32.c (gdk_text_property_to_text_list,
gdk_free_text_list, gdk_string_to_compound_text,
gdk_free_compound_text): Implement trivially, witrh a text_list
always having a single element, and a compound text always
consisting of just a single (UTF-8!) string. Let's see how well
this works.
* gdk/win32/gdkselection-win32.c (gdk_selection_convert): Fix
non-ASCII paste from the clipboard: Try getting the same formats
from the Windows clipboard that gdk_property_change() puts there:
CF_UNICODETEXT, UTF8_STRING or CF_TEXT+CF_LOCALE.
* gdk/win32/gdkproperty-win32.c (gdk_property_change): When
storing text on the clipboard, handle non-ASCII text
correctly. The logic is as follows:
If we have only ASCII characters, use CF_TEXT.
Else, if we are on NT, use CF_UNICODETEXT.
Else (we are on Win9x), if all the characters are present in the
code page of some installed locale, use CF_TEXT and also set
CF_LOCALE to that locale.
Else (still on Win9x) store as RTF. We use a very simple RTF
string, just the text, no fonts or other crap, with the non-ASCII
characters as Unicode \uN keywords. Additionally, also store the
UTF-8 string as such, under the format "UTF8_STRING", so that GDK
can also paste from the Clipboard what it has copied there. (Thus
no need to implement any RTF parser.)
(find_common_locale): New function, implements the search for a
locale for case 3 above.
* gdk/win32/gdkglobals-win32.c: New global variables
compound_text, text_uri_list, utf8_string, cf_rtf and
cf_utf8_string.
* gdk/win32/gdkim-win32.c (_gdk_ucs2_to_utf8): New function,
converts from a wchar_t string to UTF-8.
(_gdk_utf8_to_ucs2): Rename from _gdk_win32_nmbstowchar_ts.
(_gdk_utf8_to_wcs): Rename from gdk_nmbstowchar_ts.
* gdk/win32/gdkevents-win32.c (build_keypress_event): Use
_gdk_ucs2_to_utf8().
* gdk/win32/gdkselection-win32.c: Remove some unnecessary logging.
* gdk/win32/gdkdnd-win32.c: Plug memory leaks, the
gdk_drag_context_ref() was called unnecessarily in a couple of
places, meaning drag contexts were never freed. The same memory
leaks seem to be present in gdk/linux-fb/gdkselection-fb.c, BTW.
(gdk_drop_reply): For WIN32_DROPFILES drops, free the temporarily
stored file list.
* gdk/win32/gdkselection-win32.c: Clarify the use of the
sel_prop_table. Now it is used only for storing the GDK_SELECTION
"properties".
The file names dropped with WM_DROPFILES -style DND is stored
temporarily (between the drop and the target picking them up) in a
separate place.
Have a separate hash table to map selection atoms to owner
windows. This used to be quite mixed up.
(_gdk_dropfiles_store): New function, to store the dropped file
list for the drop target to possibly fetch, and clear it
afterwards, from gdk_drop_reply().
(gdk_selection_owner_get): Much simplified now.

Large changes to the Win32 backend, partially made necessary by the
2000-05-02 Tor Lillqvist <tml@iki.fi>
Large changes to the Win32 backend, partially made necessary by
the changes to the backend-independent internal
structures. Attempts to implement similar backing store stuff as
on X11. The current (CVS) version of the Win32 backend is *not* as
stable as it was before the no-flicker branch was merged. A
zipfile with that version is available from
http://www.gimp.org/win32/. That should be use by "production"
code until this CVS version is usable. (But note, the Win32
backend has never been claimed to be "production quality".)
* README.win32: Add the above comment about versions.
* gdk/gdkwindow.c: Don't use backing store for now on Win32.
* gdk/gdk.def: Update.
* gdk/gdkfont.h: Declare temporary Win32-only functions. Will
presumably be replaced by some more better mechanism as 1.4 gets
closer to release shape.
* gdk/makefile.{cygwin,msc}: Update.
* gdk/win32/*.c: Correct inclusions of the backend-specific and
internal headers. Change code according to changes in these. Use
gdk_drawable_*, not gdk_window_* where necessary.
* gdk/win32/gdkdnd-win32.c: Use MISC selector for GDK_NOTE, not
our old DND.
* gdk/win32/gdkdrawable-win32.c (gdk_win32_draw_text): Don't try
to interpret single characters as UTF-8. Thanks to Hans Breuer.
Use correct function name in warning messages.
* gdk/win32/gdkevents-win32.c: Use correct parameter lists for the
GSourceFuncs gdk_event_prepare and gdk_event_check.
(gdk_event_get_graphics_expose): Do implement, use
PeekMessage. Thanks to Hans Breuer.
(event_mask_string): Debugging function to print an GdkEventMask.
(gdk_pointer_grab): Use it.
* gdk/win32/gdkfont-win32.c: The Unicode subrange that the
(old) book I used claimed was Hangul actually is CJK Unified
Ideographs Extension A. Also, Hangul Syllables were missing.
Improve logging.
* gdk/win32/gdkgc-win32.c: Largish changes.
* gdk/win32/gdkim-win32.c (gdk_set_locale): Use
g_win32_getlocale() from GLib, and not setlocale() to get current
locale name.
* gdk/win32/gdkprivate-win32.h
* gdk/win32/gdkwin32.h: Move stuff from gdkprivate-win32.h to
gdkwin32.h, similarily as in the X11 backend.
* gdk/win32/gdkwindow-win32.c (gdk_propagate_shapes): Bugfix,
assignment was used instead of equals in if test. Thanks to Hans
Breuer.
* gdk/win32/makefile.{cygwin,msc}
* gtk/makefile.{cygwin,msc}: Updates. Better kludge to get the
path to the Win32 headers that works also with the mingw compiler.
* gtk/gtkstyle.c: Include <string.h>.

Apply the same fixes and improvements as to the gtk-1-3-win32-production
2002-01-10 Tor Lillqvist <tml@iki.fi>
Apply the same fixes and improvements as to the
gtk-1-3-win32-production branch: Bug fixes and cleanup of
selection and DND functionality. Still doesn't work as well as the
win32-production branch, though, but getting closer.
After this, need to add Archaeopteryx Software's OLE2 DND support.
* gdk/win32/gdkselection-win32.c (gdk_selection_owner_set,
gdk_selection_send_notify, generate_selection_notify): Don't use
SendMessage() to generate events for the same app, instead use
gdk_event_put().
* gdk/win32/gdkprivate-win32.h
* gdk/win32/gdkglobals-win32.c
* gdk/win32/gdkmain-win32.c
* gdk/win32/gdkevents-win32.c: Thus, remove declaration, definition,
initialisation and handling of gdk_selection_notify_msg,
gdk_selection_request_msg and gdk_selection_clear_msg.
* gdk/win32/gdkselection-win32.c (gdk_text_property_to_text_list,
gdk_free_text_list, gdk_string_to_compound_text,
gdk_free_compound_text): Implement trivially, witrh a text_list
always having a single element, and a compound text always
consisting of just a single (UTF-8!) string. Let's see how well
this works.
* gdk/win32/gdkselection-win32.c (gdk_selection_convert): Fix
non-ASCII paste from the clipboard: Try getting the same formats
from the Windows clipboard that gdk_property_change() puts there:
CF_UNICODETEXT, UTF8_STRING or CF_TEXT+CF_LOCALE.
* gdk/win32/gdkproperty-win32.c (gdk_property_change): When
storing text on the clipboard, handle non-ASCII text
correctly. The logic is as follows:
If we have only ASCII characters, use CF_TEXT.
Else, if we are on NT, use CF_UNICODETEXT.
Else (we are on Win9x), if all the characters are present in the
code page of some installed locale, use CF_TEXT and also set
CF_LOCALE to that locale.
Else (still on Win9x) store as RTF. We use a very simple RTF
string, just the text, no fonts or other crap, with the non-ASCII
characters as Unicode \uN keywords. Additionally, also store the
UTF-8 string as such, under the format "UTF8_STRING", so that GDK
can also paste from the Clipboard what it has copied there. (Thus
no need to implement any RTF parser.)
(find_common_locale): New function, implements the search for a
locale for case 3 above.
* gdk/win32/gdkglobals-win32.c: New global variables
compound_text, text_uri_list, utf8_string, cf_rtf and
cf_utf8_string.
* gdk/win32/gdkim-win32.c (_gdk_ucs2_to_utf8): New function,
converts from a wchar_t string to UTF-8.
(_gdk_utf8_to_ucs2): Rename from _gdk_win32_nmbstowchar_ts.
(_gdk_utf8_to_wcs): Rename from gdk_nmbstowchar_ts.
* gdk/win32/gdkevents-win32.c (build_keypress_event): Use
_gdk_ucs2_to_utf8().
* gdk/win32/gdkselection-win32.c: Remove some unnecessary logging.
* gdk/win32/gdkdnd-win32.c: Plug memory leaks, the
gdk_drag_context_ref() was called unnecessarily in a couple of
places, meaning drag contexts were never freed. The same memory
leaks seem to be present in gdk/linux-fb/gdkselection-fb.c, BTW.
(gdk_drop_reply): For WIN32_DROPFILES drops, free the temporarily
stored file list.
* gdk/win32/gdkselection-win32.c: Clarify the use of the
sel_prop_table. Now it is used only for storing the GDK_SELECTION
"properties".
The file names dropped with WM_DROPFILES -style DND is stored
temporarily (between the drop and the target picking them up) in a
separate place.
Have a separate hash table to map selection atoms to owner
windows. This used to be quite mixed up.
(_gdk_dropfiles_store): New function, to store the dropped file
list for the drop target to possibly fetch, and clear it
afterwards, from gdk_drop_reply().
(gdk_selection_owner_get): Much simplified now.

Bug 559408 - Transparency lost when images are copied between GTK+ and the
2009-01-29 Tor Lillqvist <tml@novell.com>
Bug 559408 - Transparency lost when images are copied between GTK+
and the clipboard on Windows
The code in gdkselection-win32.c is simplified quite a lot. When
an image is stored on the clipboard from GTK+, only the "PNG" and
CF_DIB formats are advertised. PNG is our preferred format because
it can losslessly represent any image that gdk-pixbuf can handle,
even with alpha, unambiguously. CF_DIB is also advertised because
of its ubiquitous support in Windows software.
Delayed rendering is used as before, so for other data than text
nothing is actually stored on the clipboard until some app asks
for it.
It's pointless to advertise images formats like "image/png" or
"image/x-MS-bmp" that no other Windows application is going to
look for anyway. Likewise it's pointless to store text under
formats like "text/plain" or "UTF8_STRING". Just store
CF_UNICODETEXT. CF_TEXT will be available as a synthesized format
anyways.
Office 2007 offers and asks for images in PNG format using the
registered clipboard format name "PNG", so we do likewise. If the
"PNG" format is available that is preferred when copying to GTK+
from the clipboard.
Unfortunately Word 2007 still uses CF_DIB without handling
alpha. But PowerPoint 2007 uses PNG if available and handles alpha
correctly. Both Word and Powerpoint offer PNG with alpha nicely.
Firefox and IE7 offer images that contain alpha as 32-bit version
3 BI_RGB DIBs with the undocumented "extra" bytes actually being
alpha. Also, alpha is premultiplied into the RGB bytes, presumably
because that is how AlphaBlend() wants such DIBs. That is also
taken care of. At least for Firefox it easy to be sure that a
CF_DIB on the clipboard is from Firefox.
Also some general stylistic cleanup, comment improvements, and
improvements of debugging printout especially in the clipboard
handling. Those are not detailled below.
* gdk/win32/gdkprivate-win32.h
* gdk/win32/gdkglobals-win32.c
* gdk/win32/gdkgmain-win32.c: Move some globals that were used
only in gdkselection-win32.c to be local to that file.
* gdk/win32/gdkproperty-win32.c (gdk_property_change): Don't
bother checking if text to be placed on the clipboard consists of
only ASCII.
* gdk/win32/gdkselection-win32.c: Add static variables for a list
of GdkPixbuf-supported formats, well-known registered clipboard
formats for images, and for GdkAtoms for well-known image and text
formats.
(_gdk_win32_selection_init): Initialize above static variables.
(selection_property_store) (gdk_selection_property_get)
(_gdk_selection_property_delete): Don't use a FIFO of GdkSelProps
for a window after all, it breaks testtext. See bug #163844.
(gdk_selection_convert): When converting to the TARGETS format,
i.e. when the caller wants to know what clipboard formats are
available, if PNG is available we report just that and skip
CF_DIB, JPEG and GIF even if advertised.
If CF_UNICODETEXT is available, report only UTF8_STRING.
When converting to the UTF8_STRING format, i.e. when the caller
wants text from the clipboard, try just CF_UNICODETEXT. There is
no point in trying CF_TEXT as Windows will synthesize
CF_UNICODETEXT from CF_TEXT anyway, if some app has stored just
CF_TEXT.
When converting to the image/bmp format, i.e. when the caller
wants an CF_DIB image from the clipboard, we check if the DIB is a
version 3 32-bit BI_RGB one that is likely to actually contain
alpha in the "extra" bytes. Such a DIB is likely to have
premultiplied alpha even, at least in the case of Firefox 3 and
IE7. We then edit the DIB in-place into a version 5 one in
BI_BITFIELDS format and undo the alpha premultiplication.
In any case, prepend a BMP file header before letting go of the
data which will be fed to the gdk-pixbuf bmp loader by upper
levels.
(gdk_win32_selection_add_targets): If some kind of pixmap image
format is being added, actually advertise just PNG and
CF_DIB. Note that alpha won't be stored on the clipboard through
CF_DIB. This is because gdk-pixbuf's bmp loader doesn't save
alpha. Furthermore, few if any non-GTK+ Windows apps seem to
understand a version 5 DIB with proper alpha anyway.
(_gdk_win32_selection_convert_to_dib): Simplified muchly.

W32: Massive W32 DnD fix
Massive changes to OLE2 DnD protocol, which was completely broken before:
* Keep GdkDragContext and OLE2 objects separate (don't ref/unref them
together, don't necessarily create them together).
* Keep IDataObject formats in the object itself, not in a global variable.
* Fix getdata() to look up the request target in its format list, not in the
global hash table
* Create target GdkDragContext on each drag_enter, destroy it on drag_leave,
whereas IDropTarget is created when a window becomes a drag destination
and is re-used indefinitely.
* Query the source IDataObject for its supported types, cache them in the
target (!) context. This is how GTK+ works, honestly.
* Remember current_src_object when we initiate a drag, to be able
to detect later on that the data object is ours and use a
shortcut when querying targets
* Make sure GDK_DRAG_MOTION is only sent when something changes
* Support GTK drag cursors
* Ensure that exotic GTK clipboard formats are registered
(but try to avoid registering formats that can't be used between applications).
* Don't enumerate internal formats
* Ensure that DnD indicator window can't accept drags or receive any kind of input
(use WS_EX_TRANSPARENT).
* Remove unneeded indentation in _gdk_win32_dnd_do_dragdrop()
* Fix indentation in gdk_win32_drag_context_drop_finish()
* Remove obsolete comments in _gdk_win32_window_register_dnd()
* Check for DnD in progress when processing WM_KILLFOCUS, don't emit a grab
break event in such cases (this allows alt-tabbing while DnD is in progress,
though there may be lingering issues with focus after dropping...)
* Support Shell ID List -> text/uri-list conversion, now it's possible
to drop files (dragged from Explorer) on GTK+ applications
* Explicitly use RegisterClipboardFormatA() when we know that the string
is not in unicode. Otherwise explicitly use RegisterClipboardFormatW()
with a UTF8->UTF16 converted string
* Fix _gdk_win32_display_get_selection_owner() to correctly bail
when selection owner HWND is NULL (looking up GdkWindow for NULL
HWND always succeeds and returns the root window - not the intended
effect)
* More logging
* Send DROP_FINISHED event after DnD loop ends
* Send STATUS event on feedback
* Move GetKeyboardState() and related code into _gdk_win32_window_drag_begin(),
so that it's closer to the point where last_pt and start_pt are set
* Use & 0x80 to check for the key being pressed. Windows will set low-order bit
to 1 for all mouse buttons to indicate that they are toggled, so simply
checking for the value not being 0 is not enough anymore.
This is probably a new thing in modern W32 that didn't exist before
(OLE2 DnD code is old).
* Fixed (hopefully) and simplified HiDPI parts of the code.
Also adds managed DnD implementation for W32 GDK backend (for both
OLE2 and LOCAL protocols). Mostly a copy of the X11 backend code, but
there are some minor differences:
* doesn't use drag_window field in GdkDragContext,
uses the one in GdkWin32DragContext exclusively
* subtracts hotspot offset from the window coordinates when showing
the dragback animation
* tries to consistently support scaling and caches the scale
in the context
* Some keynav code is removed (places where grabbing/ungrabbing should
happen is marked with TODOs), and the rest is probably inert.
Also significantly changes the way selection (and clipboard) is handled
(as MSDN rightly notes, the handling for DnD and Clipboard
formats is virtually the same, so it makes sense to handle
both with the same code):
* Don't spam GDK_OWNER_CHANGE, send them only when owner
actually changes
* Open clipboard when our process becomes the clipboard owner
(we are doing it anyway, to empty the clipboard and *become* the owner),
and then don't close it until a scheduled selection request event
(with TARGETS target) is received. Process that event by announcing
all of our supported formats (by that time add_targets() should have
been called up the stack, thus the formats are known; just in case,
add_targets() will also schedule a selection request, if one isn't
scheduled already, so that late-coming formats can still be announced).
* Allow clipboard opening for selection_convert() to be delayed if it
fails initially.
* The last two points above should fix all the bugs about GTK+ rising
too much ruckus over OpenClipboard() failures, as owner change
*is allowed* to fail (though not all callers currently handle
that case), and selection_convert() is asynchronous to begin with.
Still, this is somewhat risky, as there's a possibility that the
code will work in unexpected ways and the clipboard will remain open.
There's now logging to track the clipboard being opened and closed,
and a number of failsafes that try to ensure that it isn't kept open
for no reason.
* Added copious notes on the way clipboard works on X11, Windows and GDK-W32,
also removed old comments in DnD implementation, replaced some of them
with the new ones
* A lot of crufty module-global variables are stuffed into a singleton
object, GdkWin32Selection. It's technically possible to make it a
sub-object of the Display object (the way Wayland backend does),
but since Display object on W32 is a singleton anyway... why bother?
* Fixed the send_change_events() a bit (was slightly broken in one of the
previous iterations)
* Ensure that there's no confusion between selection conversion (an artifact
term from X11) and selection transmutation (changing the data to be W32-compatible)
* Put all the transmutation code and format-target-matching code into gdkselection-win32.c,
now this code isn't spread across multiple files.
* Consequently, moved some code away from gdkproperty-win32.c and gdkdnd-win32.c
* Extensive format transmutation checks for OLE2 DnD and clipboard.
We now keep track of which format mappings are for transmutations,
and which aren't (for example, when formats are passed as-is, or when
a registered name is just an alias)
* Put transmutation code into separate functions
* Ensure that drop target keeps a format->target map for supported formats,
this is useful when selection_convert() is called, as it only receives a
single target and no hints on the format from which the data should
be transmuted into this target.
* Add clear_targets() on W32, to de called by GTK
* Use g_set_object() instead of g_ref_object() where it is allowed.
* Fix indentation (and convert tabs to spaces), remove unused variables

Bug 559408 - Transparency lost when images are copied between GTK+ and the
2009-01-29 Tor Lillqvist <tml@novell.com>
Bug 559408 - Transparency lost when images are copied between GTK+
and the clipboard on Windows
The code in gdkselection-win32.c is simplified quite a lot. When
an image is stored on the clipboard from GTK+, only the "PNG" and
CF_DIB formats are advertised. PNG is our preferred format because
it can losslessly represent any image that gdk-pixbuf can handle,
even with alpha, unambiguously. CF_DIB is also advertised because
of its ubiquitous support in Windows software.
Delayed rendering is used as before, so for other data than text
nothing is actually stored on the clipboard until some app asks
for it.
It's pointless to advertise images formats like "image/png" or
"image/x-MS-bmp" that no other Windows application is going to
look for anyway. Likewise it's pointless to store text under
formats like "text/plain" or "UTF8_STRING". Just store
CF_UNICODETEXT. CF_TEXT will be available as a synthesized format
anyways.
Office 2007 offers and asks for images in PNG format using the
registered clipboard format name "PNG", so we do likewise. If the
"PNG" format is available that is preferred when copying to GTK+
from the clipboard.
Unfortunately Word 2007 still uses CF_DIB without handling
alpha. But PowerPoint 2007 uses PNG if available and handles alpha
correctly. Both Word and Powerpoint offer PNG with alpha nicely.
Firefox and IE7 offer images that contain alpha as 32-bit version
3 BI_RGB DIBs with the undocumented "extra" bytes actually being
alpha. Also, alpha is premultiplied into the RGB bytes, presumably
because that is how AlphaBlend() wants such DIBs. That is also
taken care of. At least for Firefox it easy to be sure that a
CF_DIB on the clipboard is from Firefox.
Also some general stylistic cleanup, comment improvements, and
improvements of debugging printout especially in the clipboard
handling. Those are not detailled below.
* gdk/win32/gdkprivate-win32.h
* gdk/win32/gdkglobals-win32.c
* gdk/win32/gdkgmain-win32.c: Move some globals that were used
only in gdkselection-win32.c to be local to that file.
* gdk/win32/gdkproperty-win32.c (gdk_property_change): Don't
bother checking if text to be placed on the clipboard consists of
only ASCII.
* gdk/win32/gdkselection-win32.c: Add static variables for a list
of GdkPixbuf-supported formats, well-known registered clipboard
formats for images, and for GdkAtoms for well-known image and text
formats.
(_gdk_win32_selection_init): Initialize above static variables.
(selection_property_store) (gdk_selection_property_get)
(_gdk_selection_property_delete): Don't use a FIFO of GdkSelProps
for a window after all, it breaks testtext. See bug #163844.
(gdk_selection_convert): When converting to the TARGETS format,
i.e. when the caller wants to know what clipboard formats are
available, if PNG is available we report just that and skip
CF_DIB, JPEG and GIF even if advertised.
If CF_UNICODETEXT is available, report only UTF8_STRING.
When converting to the UTF8_STRING format, i.e. when the caller
wants text from the clipboard, try just CF_UNICODETEXT. There is
no point in trying CF_TEXT as Windows will synthesize
CF_UNICODETEXT from CF_TEXT anyway, if some app has stored just
CF_TEXT.
When converting to the image/bmp format, i.e. when the caller
wants an CF_DIB image from the clipboard, we check if the DIB is a
version 3 32-bit BI_RGB one that is likely to actually contain
alpha in the "extra" bytes. Such a DIB is likely to have
premultiplied alpha even, at least in the case of Firefox 3 and
IE7. We then edit the DIB in-place into a version 5 one in
BI_BITFIELDS format and undo the alpha premultiplication.
In any case, prepend a BMP file header before letting go of the
data which will be fed to the gdk-pixbuf bmp loader by upper
levels.
(gdk_win32_selection_add_targets): If some kind of pixmap image
format is being added, actually advertise just PNG and
CF_DIB. Note that alpha won't be stored on the clipboard through
CF_DIB. This is because gdk-pixbuf's bmp loader doesn't save
alpha. Furthermore, few if any non-GTK+ Windows apps seem to
understand a version 5 DIB with proper alpha anyway.
(_gdk_win32_selection_convert_to_dib): Simplified muchly.

* Keep GdkDragContext and OLE2 objects separate (don't ref/unref them

* Keep IDataObject formats in the object itself, not in a global variable.

* Create target GdkDragContext on each drag_enter, destroy it on drag_leave,
whereas IDropTarget is created when a window becomes a drag destination
and is re-used indefinitely.
* Query the source IDataObject for its supported types, cache them in the
target (!) context. This is how GTK+ works, honestly.
* Remember current_src_object when we initiate a drag, to be able
to detect later on that the data object is ours and use a
shortcut when querying targets
* Make sure GDK_DRAG_MOTION is only sent when something changes
* Support GTK drag cursors
* Ensure that exotic GTK clipboard formats are registered
(but try to avoid registering formats that can't be used between applications).
* Don't enumerate internal formats
* Ensure that DnD indicator window can't accept drags or receive any kind of input
(use WS_EX_TRANSPARENT).
* Remove unneeded indentation in _gdk_win32_dnd_do_dragdrop()
* Fix indentation in gdk_win32_drag_context_drop_finish()
* Remove obsolete comments in _gdk_win32_window_register_dnd()
* Check for DnD in progress when processing WM_KILLFOCUS, don't emit a grab
break event in such cases (this allows alt-tabbing while DnD is in progress,
though there may be lingering issues with focus after dropping...)
* Support Shell ID List -> text/uri-list conversion, now it's possible
to drop files (dragged from Explorer) on GTK+ applications
* Explicitly use RegisterClipboardFormatA() when we know that the string
is not in unicode. Otherwise explicitly use RegisterClipboardFormatW()
with a UTF8->UTF16 converted string
* Fix _gdk_win32_display_get_selection_owner() to correctly bail
when selection owner HWND is NULL (looking up GdkWindow for NULL
HWND always succeeds and returns the root window - not the intended
effect)
* More logging
* Send DROP_FINISHED event after DnD loop ends
* Send STATUS event on feedback
* Move GetKeyboardState() and related code into _gdk_win32_window_drag_begin(),
so that it's closer to the point where last_pt and start_pt are set
* Use & 0x80 to check for the key being pressed. Windows will set low-order bit
to 1 for all mouse buttons to indicate that they are toggled, so simply
checking for the value not being 0 is not enough anymore.
This is probably a new thing in modern W32 that didn't exist before
(OLE2 DnD code is old).
* Fixed (hopefully) and simplified HiDPI parts of the code.
Also adds managed DnD implementation for W32 GDK backend (for both
OLE2 and LOCAL protocols). Mostly a copy of the X11 backend code, but
there are some minor differences:
* doesn't use drag_window field in GdkDragContext,
uses the one in GdkWin32DragContext exclusively
* subtracts hotspot offset from the window coordinates when showing
the dragback animation
* tries to consistently support scaling and caches the scale
in the context
* Some keynav code is removed (places where grabbing/ungrabbing should
happen is marked with TODOs), and the rest is probably inert.
Also significantly changes the way selection (and clipboard) is handled
(as MSDN rightly notes, the handling for DnD and Clipboard
formats is virtually the same, so it makes sense to handle
both with the same code):
* Don't spam GDK_OWNER_CHANGE, send them only when owner
actually changes
* Open clipboard when our process becomes the clipboard owner
(we are doing it anyway, to empty the clipboard and *become* the owner),
and then don't close it until a scheduled selection request event
(with TARGETS target) is received. Process that event by announcing
all of our supported formats (by that time add_targets() should have
been called up the stack, thus the formats are known; just in case,
add_targets() will also schedule a selection request, if one isn't
scheduled already, so that late-coming formats can still be announced).
* Allow clipboard opening for selection_convert() to be delayed if it
fails initially.
* The last two points above should fix all the bugs about GTK+ rising
too much ruckus over OpenClipboard() failures, as owner change
*is allowed* to fail (though not all callers currently handle
that case), and selection_convert() is asynchronous to begin with.
Still, this is somewhat risky, as there's a possibility that the
code will work in unexpected ways and the clipboard will remain open.
There's now logging to track the clipboard being opened and closed,
and a number of failsafes that try to ensure that it isn't kept open
for no reason.
* Added copious notes on the way clipboard works on X11, Windows and GDK-W32,
also removed old comments in DnD implementation, replaced some of them
with the new ones
* A lot of crufty module-global variables are stuffed into a singleton
object, GdkWin32Selection. It's technically possible to make it a
sub-object of the Display object (the way Wayland backend does),
but since Display object on W32 is a singleton anyway... why bother?
* Fixed the send_change_events() a bit (was slightly broken in one of the
previous iterations)
* Ensure that there's no confusion between selection conversion (an artifact
term from X11) and selection transmutation (changing the data to be W32-compatible)
* Put all the transmutation code and format-target-matching code into gdkselection-win32.c,
now this code isn't spread across multiple files.
* Consequently, moved some code away from gdkproperty-win32.c and gdkdnd-win32.c
* Extensive format transmutation checks for OLE2 DnD and clipboard.
We now keep track of which format mappings are for transmutations,
and which aren't (for example, when formats are passed as-is, or when
a registered name is just an alias)
* Put transmutation code into separate functions
* Ensure that drop target keeps a format->target map for supported formats,
this is useful when selection_convert() is called, as it only receives a
single target and no hints on the format from which the data should
be transmuted into this target.
* Add clear_targets() on W32, to de called by GTK
* Use g_set_object() instead of g_ref_object() where it is allowed.
* Fix indentation (and convert tabs to spaces), remove unused variables

Bug 559408 - Transparency lost when images are copied between GTK+ and the
2009-01-29 Tor Lillqvist <tml@novell.com>
Bug 559408 - Transparency lost when images are copied between GTK+
and the clipboard on Windows
The code in gdkselection-win32.c is simplified quite a lot. When
an image is stored on the clipboard from GTK+, only the "PNG" and
CF_DIB formats are advertised. PNG is our preferred format because
it can losslessly represent any image that gdk-pixbuf can handle,
even with alpha, unambiguously. CF_DIB is also advertised because
of its ubiquitous support in Windows software.
Delayed rendering is used as before, so for other data than text
nothing is actually stored on the clipboard until some app asks
for it.
It's pointless to advertise images formats like "image/png" or
"image/x-MS-bmp" that no other Windows application is going to
look for anyway. Likewise it's pointless to store text under
formats like "text/plain" or "UTF8_STRING". Just store
CF_UNICODETEXT. CF_TEXT will be available as a synthesized format
anyways.
Office 2007 offers and asks for images in PNG format using the
registered clipboard format name "PNG", so we do likewise. If the
"PNG" format is available that is preferred when copying to GTK+
from the clipboard.
Unfortunately Word 2007 still uses CF_DIB without handling
alpha. But PowerPoint 2007 uses PNG if available and handles alpha
correctly. Both Word and Powerpoint offer PNG with alpha nicely.
Firefox and IE7 offer images that contain alpha as 32-bit version
3 BI_RGB DIBs with the undocumented "extra" bytes actually being
alpha. Also, alpha is premultiplied into the RGB bytes, presumably
because that is how AlphaBlend() wants such DIBs. That is also
taken care of. At least for Firefox it easy to be sure that a
CF_DIB on the clipboard is from Firefox.
Also some general stylistic cleanup, comment improvements, and
improvements of debugging printout especially in the clipboard
handling. Those are not detailled below.
* gdk/win32/gdkprivate-win32.h
* gdk/win32/gdkglobals-win32.c
* gdk/win32/gdkgmain-win32.c: Move some globals that were used
only in gdkselection-win32.c to be local to that file.
* gdk/win32/gdkproperty-win32.c (gdk_property_change): Don't
bother checking if text to be placed on the clipboard consists of
only ASCII.
* gdk/win32/gdkselection-win32.c: Add static variables for a list
of GdkPixbuf-supported formats, well-known registered clipboard
formats for images, and for GdkAtoms for well-known image and text
formats.
(_gdk_win32_selection_init): Initialize above static variables.
(selection_property_store) (gdk_selection_property_get)
(_gdk_selection_property_delete): Don't use a FIFO of GdkSelProps
for a window after all, it breaks testtext. See bug #163844.
(gdk_selection_convert): When converting to the TARGETS format,
i.e. when the caller wants to know what clipboard formats are
available, if PNG is available we report just that and skip
CF_DIB, JPEG and GIF even if advertised.
If CF_UNICODETEXT is available, report only UTF8_STRING.
When converting to the UTF8_STRING format, i.e. when the caller
wants text from the clipboard, try just CF_UNICODETEXT. There is
no point in trying CF_TEXT as Windows will synthesize
CF_UNICODETEXT from CF_TEXT anyway, if some app has stored just
CF_TEXT.
When converting to the image/bmp format, i.e. when the caller
wants an CF_DIB image from the clipboard, we check if the DIB is a
version 3 32-bit BI_RGB one that is likely to actually contain
alpha in the "extra" bytes. Such a DIB is likely to have
premultiplied alpha even, at least in the case of Firefox 3 and
IE7. We then edit the DIB in-place into a version 5 one in
BI_BITFIELDS format and undo the alpha premultiplication.
In any case, prepend a BMP file header before letting go of the
data which will be fed to the gdk-pixbuf bmp loader by upper
levels.
(gdk_win32_selection_add_targets): If some kind of pixmap image
format is being added, actually advertise just PNG and
CF_DIB. Note that alpha won't be stored on the clipboard through
CF_DIB. This is because gdk-pixbuf's bmp loader doesn't save
alpha. Furthermore, few if any non-GTK+ Windows apps seem to
understand a version 5 DIB with proper alpha anyway.
(_gdk_win32_selection_convert_to_dib): Simplified muchly.

W32: Massive W32 DnD fix
Massive changes to OLE2 DnD protocol, which was completely broken before:
* Keep GdkDragContext and OLE2 objects separate (don't ref/unref them
together, don't necessarily create them together).
* Keep IDataObject formats in the object itself, not in a global variable.
* Fix getdata() to look up the request target in its format list, not in the
global hash table
* Create target GdkDragContext on each drag_enter, destroy it on drag_leave,
whereas IDropTarget is created when a window becomes a drag destination
and is re-used indefinitely.
* Query the source IDataObject for its supported types, cache them in the
target (!) context. This is how GTK+ works, honestly.
* Remember current_src_object when we initiate a drag, to be able

Bug 559408 - Transparency lost when images are copied between GTK+
and the clipboard on Windows
The code in gdkselection-win32.c is simplified quite a lot. When
an image is stored on the clipboard from GTK+, only the "PNG" and
CF_DIB formats are advertised. PNG is our preferred format because
it can losslessly represent any image that gdk-pixbuf can handle,
even with alpha, unambiguously. CF_DIB is also advertised because
of its ubiquitous support in Windows software.
Delayed rendering is used as before, so for other data than text
nothing is actually stored on the clipboard until some app asks
for it.
It's pointless to advertise images formats like "image/png" or
"image/x-MS-bmp" that no other Windows application is going to
look for anyway. Likewise it's pointless to store text under
formats like "text/plain" or "UTF8_STRING". Just store
CF_UNICODETEXT. CF_TEXT will be available as a synthesized format
anyways.
Office 2007 offers and asks for images in PNG format using the
registered clipboard format name "PNG", so we do likewise. If the
"PNG" format is available that is preferred when copying to GTK+
from the clipboard.
Unfortunately Word 2007 still uses CF_DIB without handling
alpha. But PowerPoint 2007 uses PNG if available and handles alpha
correctly. Both Word and Powerpoint offer PNG with alpha nicely.
Firefox and IE7 offer images that contain alpha as 32-bit version
3 BI_RGB DIBs with the undocumented "extra" bytes actually being
alpha. Also, alpha is premultiplied into the RGB bytes, presumably
because that is how AlphaBlend() wants such DIBs. That is also
taken care of. At least for Firefox it easy to be sure that a
CF_DIB on the clipboard is from Firefox.
Also some general stylistic cleanup, comment improvements, and
improvements of debugging printout especially in the clipboard
handling. Those are not detailled below.
* gdk/win32/gdkprivate-win32.h
* gdk/win32/gdkglobals-win32.c
* gdk/win32/gdkgmain-win32.c: Move some globals that were used
only in gdkselection-win32.c to be local to that file.
* gdk/win32/gdkproperty-win32.c (gdk_property_change): Don't
bother checking if text to be placed on the clipboard consists of
only ASCII.
* gdk/win32/gdkselection-win32.c: Add static variables for a list
of GdkPixbuf-supported formats, well-known registered clipboard
formats for images, and for GdkAtoms for well-known image and text
formats.
(_gdk_win32_selection_init): Initialize above static variables.
(selection_property_store) (gdk_selection_property_get)
(_gdk_selection_property_delete): Don't use a FIFO of GdkSelProps
for a window after all, it breaks testtext. See bug #163844.
(gdk_selection_convert): When converting to the TARGETS format,
i.e. when the caller wants to know what clipboard formats are
available, if PNG is available we report just that and skip
CF_DIB, JPEG and GIF even if advertised.
If CF_UNICODETEXT is available, report only UTF8_STRING.
When converting to the UTF8_STRING format, i.e. when the caller
wants text from the clipboard, try just CF_UNICODETEXT. There is
no point in trying CF_TEXT as Windows will synthesize
CF_UNICODETEXT from CF_TEXT anyway, if some app has stored just
CF_TEXT.
When converting to the image/bmp format, i.e. when the caller
wants an CF_DIB image from the clipboard, we check if the DIB is a
version 3 32-bit BI_RGB one that is likely to actually contain
alpha in the "extra" bytes. Such a DIB is likely to have
premultiplied alpha even, at least in the case of Firefox 3 and
IE7. We then edit the DIB in-place into a version 5 one in
BI_BITFIELDS format and undo the alpha premultiplication.
In any case, prepend a BMP file header before letting go of the
data which will be fed to the gdk-pixbuf bmp loader by upper
levels.
(gdk_win32_selection_add_targets): If some kind of pixmap image
format is being added, actually advertise just PNG and
CF_DIB. Note that alpha won't be stored on the clipboard through
CF_DIB. This is because gdk-pixbuf's bmp loader doesn't save
alpha. Furthermore, few if any non-GTK+ Windows apps seem to
understand a version 5 DIB with proper alpha anyway.
(_gdk_win32_selection_convert_to_dib): Simplified muchly.

#ifndef G_DISABLE_CHECKS

gdk/win32/gdkprivate-win32.h gdk/win32/gdkglobals-win32.c Add more
2005-11-01 Tor Lillqvist <tml@novell.com>
* gdk/win32/gdkprivate-win32.h
* gdk/win32/gdkglobals-win32.c
* gdk/win32/gdkmain-win32.c (_gdk_windowing_init): Add more
pre-interned GdkAtoms and pre-registered clipboard formats. Sort
their declarations, definitions and assignments into a more
logical and consistent order.
* gdk/win32/gdkmain-win32.c (_gdk_win32_cf_to_string): Include the
CF_ prefix for the predefined clipboard format names. Put quotes
around registered format names to distinguish them.
* gdk/win32/gdkproperty-win32.c (gdk_property_change): Return
immediately with a warning if the property type is STRING, TEXT,
COMPOUND_TEXT or SAVE_TARGETS, as these are X11-specific that we
should never pretend to handle on Win32. Handle only UTF8_STRING
here, other formats with delayed rendering. Use \uc1 instead of
\uc0 when generating Rich Text Format for easier testability on
XP, where WordPad misinterprets \uc0 encoded characters. Add more
GDK_NOTE debugging output for Clipboard operations.
* gdk/win32/gdkselection-win32.c: Debugging printout improvements.
(gdk_selection_convert): Don't pretent to handle STRING, just
UTF8_STRING. Streamline error handling, don't unnecessarily have a
GError which then isn't used for anything anyway if it gets set.
(gdk_win32_selection_add_targets): Skip also STRING, TEXT,
COMPOUND_TEXT and SAVE_TARGETS in addition to UTF8_STRING.

W32: Massive W32 DnD fix
Massive changes to OLE2 DnD protocol, which was completely broken before:
* Keep GdkDragContext and OLE2 objects separate (don't ref/unref them
together, don't necessarily create them together).
* Keep IDataObject formats in the object itself, not in a global variable.
* Fix getdata() to look up the request target in its format list, not in the
global hash table
* Create target GdkDragContext on each drag_enter, destroy it on drag_leave,
whereas IDropTarget is created when a window becomes a drag destination
and is re-used indefinitely.
* Query the source IDataObject for its supported types, cache them in the
target (!) context. This is how GTK+ works, honestly.
* Remember current_src_object when we initiate a drag, to be able
to detect later on that the data object is ours and use a
shortcut when querying targets
* Make sure GDK_DRAG_MOTION is only sent when something changes
* Support GTK drag cursors
* Ensure that exotic GTK clipboard formats are registered
(but try to avoid registering formats that can't be used between applications).
* Don't enumerate internal formats
* Ensure that DnD indicator window can't accept drags or receive any kind of input
(use WS_EX_TRANSPARENT).
* Remove unneeded indentation in _gdk_win32_dnd_do_dragdrop()
* Fix indentation in gdk_win32_drag_context_drop_finish()
* Remove obsolete comments in _gdk_win32_window_register_dnd()
* Check for DnD in progress when processing WM_KILLFOCUS, don't emit a grab
break event in such cases (this allows alt-tabbing while DnD is in progress,
though there may be lingering issues with focus after dropping...)
* Support Shell ID List -> text/uri-list conversion, now it's possible
to drop files (dragged from Explorer) on GTK+ applications
* Explicitly use RegisterClipboardFormatA() when we know that the string
is not in unicode. Otherwise explicitly use RegisterClipboardFormatW()
with a UTF8->UTF16 converted string
* Fix _gdk_win32_display_get_selection_owner() to correctly bail
when selection owner HWND is NULL (looking up GdkWindow for NULL
HWND always succeeds and returns the root window - not the intended
effect)
* More logging
* Send DROP_FINISHED event after DnD loop ends
* Send STATUS event on feedback
* Move GetKeyboardState() and related code into _gdk_win32_window_drag_begin(),
so that it's closer to the point where last_pt and start_pt are set
* Use & 0x80 to check for the key being pressed. Windows will set low-order bit
to 1 for all mouse buttons to indicate that they are toggled, so simply
checking for the value not being 0 is not enough anymore.
This is probably a new thing in modern W32 that didn't exist before
(OLE2 DnD code is old).
* Fixed (hopefully) and simplified HiDPI parts of the code.
Also adds managed DnD implementation for W32 GDK backend (for both
OLE2 and LOCAL protocols). Mostly a copy of the X11 backend code, but
there are some minor differences:
* doesn't use drag_window field in GdkDragContext,
uses the one in GdkWin32DragContext exclusively
* subtracts hotspot offset from the window coordinates when showing
the dragback animation
* tries to consistently support scaling and caches the scale
in the context
* Some keynav code is removed (places where grabbing/ungrabbing should
happen is marked with TODOs), and the rest is probably inert.
Also significantly changes the way selection (and clipboard) is handled
(as MSDN rightly notes, the handling for DnD and Clipboard
formats is virtually the same, so it makes sense to handle
both with the same code):
* Don't spam GDK_OWNER_CHANGE, send them only when owner
actually changes
* Open clipboard when our process becomes the clipboard owner
(we are doing it anyway, to empty the clipboard and *become* the owner),
and then don't close it until a scheduled selection request event
(with TARGETS target) is received. Process that event by announcing
all of our supported formats (by that time add_targets() should have
been called up the stack, thus the formats are known; just in case,
add_targets() will also schedule a selection request, if one isn't
scheduled already, so that late-coming formats can still be announced).
* Allow clipboard opening for selection_convert() to be delayed if it
fails initially.
* The last two points above should fix all the bugs about GTK+ rising
too much ruckus over OpenClipboard() failures, as owner change
*is allowed* to fail (though not all callers currently handle
that case), and selection_convert() is asynchronous to begin with.
Still, this is somewhat risky, as there's a possibility that the
code will work in unexpected ways and the clipboard will remain open.
There's now logging to track the clipboard being opened and closed,
and a number of failsafes that try to ensure that it isn't kept open
for no reason.
* Added copious notes on the way clipboard works on X11, Windows and GDK-W32,
also removed old comments in DnD implementation, replaced some of them
with the new ones
* A lot of crufty module-global variables are stuffed into a singleton
object, GdkWin32Selection. It's technically possible to make it a
sub-object of the Display object (the way Wayland backend does),
but since Display object on W32 is a singleton anyway... why bother?
* Fixed the send_change_events() a bit (was slightly broken in one of the
previous iterations)
* Ensure that there's no confusion between selection conversion (an artifact
term from X11) and selection transmutation (changing the data to be W32-compatible)
* Put all the transmutation code and format-target-matching code into gdkselection-win32.c,
now this code isn't spread across multiple files.
* Consequently, moved some code away from gdkproperty-win32.c and gdkdnd-win32.c
* Extensive format transmutation checks for OLE2 DnD and clipboard.
We now keep track of which format mappings are for transmutations,
and which aren't (for example, when formats are passed as-is, or when
a registered name is just an alias)
* Put transmutation code into separate functions
* Ensure that drop target keeps a format->target map for supported formats,
this is useful when selection_convert() is called, as it only receives a
single target and no hints on the format from which the data should
be transmuted into this target.
* Add clear_targets() on W32, to de called by GTK
* Use g_set_object() instead of g_ref_object() where it is allowed.
* Fix indentation (and convert tabs to spaces), remove unused variables

* Use g_set_object() instead of g_ref_object() where it is allowed.
* Fix indentation (and convert tabs to spaces), remove unused variables

Bug 559408 - Transparency lost when images are copied between GTK+ and the
2009-01-29 Tor Lillqvist <tml@novell.com>
Bug 559408 - Transparency lost when images are copied between GTK+
and the clipboard on Windows
The code in gdkselection-win32.c is simplified quite a lot. When
an image is stored on the clipboard from GTK+, only the "PNG" and
CF_DIB formats are advertised. PNG is our preferred format because
it can losslessly represent any image that gdk-pixbuf can handle,
even with alpha, unambiguously. CF_DIB is also advertised because
of its ubiquitous support in Windows software.
Delayed rendering is used as before, so for other data than text
nothing is actually stored on the clipboard until some app asks
for it.
It's pointless to advertise images formats like "image/png" or
"image/x-MS-bmp" that no other Windows application is going to
look for anyway. Likewise it's pointless to store text under
formats like "text/plain" or "UTF8_STRING". Just store
CF_UNICODETEXT. CF_TEXT will be available as a synthesized format
anyways.
Office 2007 offers and asks for images in PNG format using the
registered clipboard format name "PNG", so we do likewise. If the
"PNG" format is available that is preferred when copying to GTK+
from the clipboard.
Unfortunately Word 2007 still uses CF_DIB without handling
alpha. But PowerPoint 2007 uses PNG if available and handles alpha
correctly. Both Word and Powerpoint offer PNG with alpha nicely.
Firefox and IE7 offer images that contain alpha as 32-bit version
3 BI_RGB DIBs with the undocumented "extra" bytes actually being
alpha. Also, alpha is premultiplied into the RGB bytes, presumably
because that is how AlphaBlend() wants such DIBs. That is also
taken care of. At least for Firefox it easy to be sure that a
CF_DIB on the clipboard is from Firefox.
Also some general stylistic cleanup, comment improvements, and
improvements of debugging printout especially in the clipboard
handling. Those are not detailled below.
* gdk/win32/gdkprivate-win32.h
* gdk/win32/gdkglobals-win32.c
* gdk/win32/gdkgmain-win32.c: Move some globals that were used
only in gdkselection-win32.c to be local to that file.
* gdk/win32/gdkproperty-win32.c (gdk_property_change): Don't
bother checking if text to be placed on the clipboard consists of
only ASCII.
* gdk/win32/gdkselection-win32.c: Add static variables for a list
of GdkPixbuf-supported formats, well-known registered clipboard
formats for images, and for GdkAtoms for well-known image and text
formats.
(_gdk_win32_selection_init): Initialize above static variables.
(selection_property_store) (gdk_selection_property_get)
(_gdk_selection_property_delete): Don't use a FIFO of GdkSelProps
for a window after all, it breaks testtext. See bug #163844.
(gdk_selection_convert): When converting to the TARGETS format,
i.e. when the caller wants to know what clipboard formats are
available, if PNG is available we report just that and skip
CF_DIB, JPEG and GIF even if advertised.
If CF_UNICODETEXT is available, report only UTF8_STRING.
When converting to the UTF8_STRING format, i.e. when the caller
wants text from the clipboard, try just CF_UNICODETEXT. There is
no point in trying CF_TEXT as Windows will synthesize
CF_UNICODETEXT from CF_TEXT anyway, if some app has stored just
CF_TEXT.
When converting to the image/bmp format, i.e. when the caller
wants an CF_DIB image from the clipboard, we check if the DIB is a
version 3 32-bit BI_RGB one that is likely to actually contain
alpha in the "extra" bytes. Such a DIB is likely to have
premultiplied alpha even, at least in the case of Firefox 3 and
IE7. We then edit the DIB in-place into a version 5 one in
BI_BITFIELDS format and undo the alpha premultiplication.
In any case, prepend a BMP file header before letting go of the
data which will be fed to the gdk-pixbuf bmp loader by upper
levels.
(gdk_win32_selection_add_targets): If some kind of pixmap image
format is being added, actually advertise just PNG and
CF_DIB. Note that alpha won't be stored on the clipboard through
CF_DIB. This is because gdk-pixbuf's bmp loader doesn't save
alpha. Furthermore, few if any non-GTK+ Windows apps seem to
understand a version 5 DIB with proper alpha anyway.
(_gdk_win32_selection_convert_to_dib): Simplified muchly.

W32: Massive W32 DnD fix
Massive changes to OLE2 DnD protocol, which was completely broken before:
* Keep GdkDragContext and OLE2 objects separate (don't ref/unref them
together, don't necessarily create them together).
* Keep IDataObject formats in the object itself, not in a global variable.
* Fix getdata() to look up the request target in its format list, not in the
global hash table
* Create target GdkDragContext on each drag_enter, destroy it on drag_leave,
whereas IDropTarget is created when a window becomes a drag destination
and is re-used indefinitely.
* Query the source IDataObject for its supported types, cache them in the
target (!) context. This is how GTK+ works, honestly.
* Remember current_src_object when we initiate a drag, to be able
to detect later on that the data object is ours and use a
shortcut when querying targets
* Make sure GDK_DRAG_MOTION is only sent when something changes
* Support GTK drag cursors
* Ensure that exotic GTK clipboard formats are registered
(but try to avoid registering formats that can't be used between applications).
* Don't enumerate internal formats
* Ensure that DnD indicator window can't accept drags or receive any kind of input
(use WS_EX_TRANSPARENT).
* Remove unneeded indentation in _gdk_win32_dnd_do_dragdrop()
* Fix indentation in gdk_win32_drag_context_drop_finish()
* Remove obsolete comments in _gdk_win32_window_register_dnd()
* Check for DnD in progress when processing WM_KILLFOCUS, don't emit a grab
break event in such cases (this allows alt-tabbing while DnD is in progress,
though there may be lingering issues with focus after dropping...)
* Support Shell ID List -> text/uri-list conversion, now it's possible
to drop files (dragged from Explorer) on GTK+ applications
* Explicitly use RegisterClipboardFormatA() when we know that the string
is not in unicode. Otherwise explicitly use RegisterClipboardFormatW()
with a UTF8->UTF16 converted string
* Fix _gdk_win32_display_get_selection_owner() to correctly bail
when selection owner HWND is NULL (looking up GdkWindow for NULL
HWND always succeeds and returns the root window - not the intended
effect)
* More logging
* Send DROP_FINISHED event after DnD loop ends
* Send STATUS event on feedback
* Move GetKeyboardState() and related code into _gdk_win32_window_drag_begin(),
so that it's closer to the point where last_pt and start_pt are set
* Use & 0x80 to check for the key being pressed. Windows will set low-order bit
to 1 for all mouse buttons to indicate that they are toggled, so simply
checking for the value not being 0 is not enough anymore.
This is probably a new thing in modern W32 that didn't exist before
(OLE2 DnD code is old).
* Fixed (hopefully) and simplified HiDPI parts of the code.
Also adds managed DnD implementation for W32 GDK backend (for both
OLE2 and LOCAL protocols). Mostly a copy of the X11 backend code, but
there are some minor differences:
* doesn't use drag_window field in GdkDragContext,
uses the one in GdkWin32DragContext exclusively
* subtracts hotspot offset from the window coordinates when showing
the dragback animation
* tries to consistently support scaling and caches the scale
in the context
* Some keynav code is removed (places where grabbing/ungrabbing should
happen is marked with TODOs), and the rest is probably inert.
Also significantly changes the way selection (and clipboard) is handled
(as MSDN rightly notes, the handling for DnD and Clipboard
formats is virtually the same, so it makes sense to handle
both with the same code):
* Don't spam GDK_OWNER_CHANGE, send them only when owner
actually changes
* Open clipboard when our process becomes the clipboard owner
(we are doing it anyway, to empty the clipboard and *become* the owner),
and then don't close it until a scheduled selection request event
(with TARGETS target) is received. Process that event by announcing
all of our supported formats (by that time add_targets() should have
been called up the stack, thus the formats are known; just in case,
add_targets() will also schedule a selection request, if one isn't
scheduled already, so that late-coming formats can still be announced).
* Allow clipboard opening for selection_convert() to be delayed if it
fails initially.
* The last two points above should fix all the bugs about GTK+ rising
too much ruckus over OpenClipboard() failures, as owner change
*is allowed* to fail (though not all callers currently handle
that case), and selection_convert() is asynchronous to begin with.
Still, this is somewhat risky, as there's a possibility that the
code will work in unexpected ways and the clipboard will remain open.
There's now logging to track the clipboard being opened and closed,
and a number of failsafes that try to ensure that it isn't kept open
for no reason.
* Added copious notes on the way clipboard works on X11, Windows and GDK-W32,
also removed old comments in DnD implementation, replaced some of them
with the new ones
* A lot of crufty module-global variables are stuffed into a singleton
object, GdkWin32Selection. It's technically possible to make it a
sub-object of the Display object (the way Wayland backend does),
but since Display object on W32 is a singleton anyway... why bother?
* Fixed the send_change_events() a bit (was slightly broken in one of the
previous iterations)
* Ensure that there's no confusion between selection conversion (an artifact
term from X11) and selection transmutation (changing the data to be W32-compatible)
* Put all the transmutation code and format-target-matching code into gdkselection-win32.c,
now this code isn't spread across multiple files.
* Consequently, moved some code away from gdkproperty-win32.c and gdkdnd-win32.c
* Extensive format transmutation checks for OLE2 DnD and clipboard.
We now keep track of which format mappings are for transmutations,
and which aren't (for example, when formats are passed as-is, or when
a registered name is just an alias)
* Put transmutation code into separate functions
* Ensure that drop target keeps a format->target map for supported formats,
this is useful when selection_convert() is called, as it only receives a
single target and no hints on the format from which the data should
be transmuted into this target.
* Add clear_targets() on W32, to de called by GTK
* Use g_set_object() instead of g_ref_object() where it is allowed.
* Fix indentation (and convert tabs to spaces), remove unused variables

Bug 559408 - Transparency lost when images are copied between GTK+ and the
2009-01-29 Tor Lillqvist <tml@novell.com>
Bug 559408 - Transparency lost when images are copied between GTK+
and the clipboard on Windows
The code in gdkselection-win32.c is simplified quite a lot. When
an image is stored on the clipboard from GTK+, only the "PNG" and
CF_DIB formats are advertised. PNG is our preferred format because
it can losslessly represent any image that gdk-pixbuf can handle,
even with alpha, unambiguously. CF_DIB is also advertised because
of its ubiquitous support in Windows software.
Delayed rendering is used as before, so for other data than text
nothing is actually stored on the clipboard until some app asks
for it.
It's pointless to advertise images formats like "image/png" or
"image/x-MS-bmp" that no other Windows application is going to
look for anyway. Likewise it's pointless to store text under
formats like "text/plain" or "UTF8_STRING". Just store
CF_UNICODETEXT. CF_TEXT will be available as a synthesized format
anyways.
Office 2007 offers and asks for images in PNG format using the
registered clipboard format name "PNG", so we do likewise. If the
"PNG" format is available that is preferred when copying to GTK+
from the clipboard.
Unfortunately Word 2007 still uses CF_DIB without handling
alpha. But PowerPoint 2007 uses PNG if available and handles alpha
correctly. Both Word and Powerpoint offer PNG with alpha nicely.
Firefox and IE7 offer images that contain alpha as 32-bit version
3 BI_RGB DIBs with the undocumented "extra" bytes actually being
alpha. Also, alpha is premultiplied into the RGB bytes, presumably
because that is how AlphaBlend() wants such DIBs. That is also
taken care of. At least for Firefox it easy to be sure that a
CF_DIB on the clipboard is from Firefox.
Also some general stylistic cleanup, comment improvements, and
improvements of debugging printout especially in the clipboard
handling. Those are not detailled below.
* gdk/win32/gdkprivate-win32.h
* gdk/win32/gdkglobals-win32.c
* gdk/win32/gdkgmain-win32.c: Move some globals that were used
only in gdkselection-win32.c to be local to that file.
* gdk/win32/gdkproperty-win32.c (gdk_property_change): Don't
bother checking if text to be placed on the clipboard consists of
only ASCII.
* gdk/win32/gdkselection-win32.c: Add static variables for a list
of GdkPixbuf-supported formats, well-known registered clipboard
formats for images, and for GdkAtoms for well-known image and text
formats.
(_gdk_win32_selection_init): Initialize above static variables.
(selection_property_store) (gdk_selection_property_get)
(_gdk_selection_property_delete): Don't use a FIFO of GdkSelProps
for a window after all, it breaks testtext. See bug #163844.
(gdk_selection_convert): When converting to the TARGETS format,
i.e. when the caller wants to know what clipboard formats are
available, if PNG is available we report just that and skip
CF_DIB, JPEG and GIF even if advertised.
If CF_UNICODETEXT is available, report only UTF8_STRING.
When converting to the UTF8_STRING format, i.e. when the caller
wants text from the clipboard, try just CF_UNICODETEXT. There is
no point in trying CF_TEXT as Windows will synthesize
CF_UNICODETEXT from CF_TEXT anyway, if some app has stored just
CF_TEXT.
When converting to the image/bmp format, i.e. when the caller
wants an CF_DIB image from the clipboard, we check if the DIB is a
version 3 32-bit BI_RGB one that is likely to actually contain
alpha in the "extra" bytes. Such a DIB is likely to have
premultiplied alpha even, at least in the case of Firefox 3 and
IE7. We then edit the DIB in-place into a version 5 one in
BI_BITFIELDS format and undo the alpha premultiplication.
In any case, prepend a BMP file header before letting go of the
data which will be fed to the gdk-pixbuf bmp loader by upper
levels.
(gdk_win32_selection_add_targets): If some kind of pixmap image
format is being added, actually advertise just PNG and
CF_DIB. Note that alpha won't be stored on the clipboard through
CF_DIB. This is because gdk-pixbuf's bmp loader doesn't save
alpha. Furthermore, few if any non-GTK+ Windows apps seem to
understand a version 5 DIB with proper alpha anyway.
(_gdk_win32_selection_convert_to_dib): Simplified muchly.

Bug 559408 - Transparency lost when images are copied between GTK+
and the clipboard on Windows
The code in gdkselection-win32.c is simplified quite a lot. When
an image is stored on the clipboard from GTK+, only the "PNG" and
CF_DIB formats are advertised. PNG is our preferred format because
it can losslessly represent any image that gdk-pixbuf can handle,
even with alpha, unambiguously. CF_DIB is also advertised because
of its ubiquitous support in Windows software.
Delayed rendering is used as before, so for other data than text
nothing is actually stored on the clipboard until some app asks
for it.
It's pointless to advertise images formats like "image/png" or
"image/x-MS-bmp" that no other Windows application is going to
look for anyway. Likewise it's pointless to store text under

Make gdkx.h the only installed header from gdk/x11. All structures in
Fri Sep 7 11:51:44 2001 Owen Taylor <otaylor@redhat.com>
Make gdkx.h the only installed header from gdk/x11.
All structures in gdk/x11 are opaque.
* gdk/x11/Makefile.am gdk/x11/gdkx.h gdk/x11/gdkprivate-x11.h:
Don't install gdk{drawable,pixmap,window}-x11.h.
* gdk/x11/{gdkcolormap-x11.c, gdkfont-x11.c, gdkx.h, gdkvisual-x11.c:
Move GdkColormapPrivateX11, GdkFontPrivateX GdkImagePrivateX11,
GdkVisualClass into C files.
* gdk/gdkpixmap-x11.[ch]: Make gdk_pixmap_impl_get_type() static.
* gdk/x11/{gdkcolor-x11.c, gdkcursor-x11.c, gdkdrawable-x11.c,
gdkfont-x11.c, gdkgc-x11.c, gdkx.h, gdkimage-x11,gdkvisual-x11.c}
Add public functions to replace previously exported direct
structure access.
gdk_x11_colormap_get_{xdisplay,xcolormap}
gdk_x11_cursor_get_{xdisplay,xcursor},
gdk_x11_drawable_get_{xdisplay,xcursor,gdk_x11_visual_get_xvisual,
gdk_x11_font_get_{xdisplay,xfont}, gdk_x11_image_get_{xdisplay,ximage},
gdk_x11_gc_get_{xdisplay,ximage}
* gdk/gdkprivate.h gdk/gdkinternals.h: Move GdkColorInfo,
GdkEventFilter, GdkClientFilter, GdkFontPrivate to gdkinternals.
Fix a number of variables and functions that were exported
"accidentally" from GDK.
* gdk/**.[ch]: gdk => _gdk for gdk_visual_init,
gdk_events_init, gdk_input_init, gdk_dnd_init, gdk_image_exit,
gdk_input_exit, gdk_windowing_exit, gdk_event_func, gdk_event_data,
gdk_event_notify, gdk_queued_events, gdk_queued_tail,
gdk_event_new, gdk_events_queue, gdk_events_unqueue,
gdk_event_queue_find_first, gdk_event_queue_remove_link,
gdk_event_queue_append, gdk_event_button_generate,
gdk_debug_flags, gdk_default_filters, gdk_parent_root.
* gdk/x11/{gdkevents-x11.c, gdkglobals-x11.c, gdkimage-x11.c,
gdkmain-x11.c, gdkprivate-x11.h, gdk/x11/gdkwindow-x11.c}:
gdk => _gdk for gdk_event_mask_table, gkd_nevent_masks,
gdk_wm_window_protocols, gdk_leader_window, gdk_xgrab_window,
gdk_use_xshm, gdk_input_ignore_core.
* gdk/x11/xsettings-common.h (xsettings_list_insert): Add
#defines to namespace functions into the private _gdk_
namespace.
* gdk/gdkwindow.[ch] gdk/x11/gdkx.h: Add gdk_get_default_root_window ()
to replace gdk_parent_root exported variable. Adjust and
deprecate GDK_ROOT_PARENT().
* demos/{testpixbuf-drawable.c,testpixbuf-save.c}: Fix
GDK_ROOT_PARENT usage, remove includes of port-specific
headers.
* gdk/{win32,x11,fb}/gdkinput*.[ch]: s/gdk/_gdk/ for
_gdk_input_gxid_host, _gdk_input_gxid_port, _gdk_input_ignore_core,
gdk_input_devices, _gdk_input_windows, gdk_init_input_core.
* gdk/x11/{gdkevents-x11.,c gdkglobals-x11.c, gdkmain-x11.c}
docs/Changes-2.0.txt: Remove gdk_wm_protocols,
gdk_wm_delete_window functions, gdk_wm_take_focus,
use gdk_atom_intern() instead.
* gdk/linux-fb/{gdkselection-fb.c, gdkmain-fb.c, gdkprivatefb.h}
gdk/win32/{gdkselection-win32.c, gdkmgdkwin32.h, gdkprivate-win32.h}
gdk/x11/{gdkselection-x11.c gdkx.h, gtkprivate-x11.h}
gtk/gtkselection.c
Unexport gdk_selection_property, just use
gdk_atom_intern ("GDK_SELECTION").
* gdk/x11/{gdkprivate-x11.h,gdkdrawable-x11h,gdkgc-x11.c,gdkx.h}:
Unexport gdk_drawable_impl_x11_get_type, gdk_gc_x11_get_type,
GDK_GC_X11 cast macros, GdkGCX11 structures, GdkCursorPrivate,
GdkVisualprivate, gdk_x11_gc_flush.
Make a number of public exports of variables into functions
to increase encapsulation.
* gdk/gdkinternals.h gdk/gdkinput.h gdk/gdkevents.h
gdk/linux-fb/gdkmouse-fb.c: gdk_core_pointer => _gdk_core_pointer,
move to gdkinternals.h. Add gdk_device_get_core_pointer ().
* gdk/gdkprivate.h gdk/gdkpango.c gdk/gdkinternals.h
docs/Changes-2.0.txt: Unexport gdk_parent_root, gdk_error_code,
gdk_error_warnings.
* gdk/x11/{gdkcolormap-x11.c, gdkmain-x11.c, gdkx.h}
docs/Changes-2.0.txt:
s/gdk_screen/_gdk_screen/, add gdk_x11_get_default_screen()
s/gdk_root_window/_gdk_root_window/, add gdk_x11_get_default_root_xwindow()
Add gdk_x11_get_default_xdisplay().
* gdk/gdk.h gdk/gdk.c linux-fb/gdkfb.h linux-fb/gdkglobals-fb.c
win32/gdkwin32.h x11/gdkglobals-x11.c gdk/x11/gdkmain-x11.c
gdk/x11/gdkx.h: gdk/gdk.def: Add gdk_get/set_program_class,
Don't export gdk_progclass, move --class command line
option and handling to common portion of GDK.
Miscellaneous fixes:
* gdk/x11/gdkwindow-x11.c (gdk_window_set_icon_list): Fix
g_return_val_if_fail that should have been g_return_if_fail.
* gdk/gdkinternals.h gdk/gdkprivate.h: Move
gdk_synthesize_window_state() to the semi-public gdkprivate.h.
* gtk/gtkdnd.c (_gtk_drag_source_handle_event): Remove uneeded
X11 dependency.
* gdk/linux-fb/gdkmain-fb.c gdk/win32/gdkmain-win32.c gdk/TODO:
Remove unused gdk_key_repeat_disable/restore.
* linux-fb/gdkglobals-fb.c win32/gdkglobals-win32.c
x11/gdkglobals-x11.c x11/gdkprivate-x11.h gdk/gdk.def:
Remove unused gdk_null_window_warnings variable.
* gdk/Makefile.am (DIST_SUBDIRS) nanox/*: cvs remove nanox;
it can be retrieved from the repository; it is too far
from functional to be worth having people check out;
it would be easier to start from scratch, I suspect.
* gdk/x11/gdkpixmap-x11.c: Fix lvalue usage of GDK_PIXMAP_XID().
* gdk/x11/gdkkeys-x11.c gdk/gdkrgb.c gdk/gdkwindow.c
gdk/x11/gdkpango-x11.c gdk/x11/gdkselection-x11.c:
Fix some accidentally global variables and unused global variables.

gdk/x11/gdkpango-x11.c gdk/x11/gdkselection-x11.c:
Fix some accidentally global variables and unused global variables.
Add some space for future expansion to multihead.
* gdk/gdkdrawable.h: Add four reserved function pointers
for future expansion of GdkDrawableClass.
* gtk/gtkwindow.h gtk/gtkinvisible.h: Add reserved pointer
where we can put a GdkScreen * later.
