Massive changes. Too many to list here, but I'll try a summary:
2002-02-17 Tor Lillqvist <tml@iki.fi>
* gdk/win32/*.c: Massive changes. Too many to list here, but I'll
try a summary:
1) Unify GdkPixmap and GdkImage implementation: For each
GdkPixmap, allocate a GdkImage, and vice versa.
GdkPixmapImplWin32Data has a pointer to the GdkImage.
GdkImage::windowing_data is a pointer to the GdkPixmap.
This simplifies many pixmap and image related functions a lot, and
reduces duplicated code snippets. For instance, there is only one
place in gdk/win32 where CreateDIBSection() is called, in the
function _gdk_win32_new_pixmap(). Converting a bitmap (GdkPixmap)
to a Windows region is almost trivial, with the bitmap bits being
readily accessible in the associated GdkImage.
All blitting between GdkPixmaps, GdkWindows and GdkImages goes
through handled the _gdk_win32_blit() function, which calls
different functions to handle the cases of blitting from pixmaps,
inside windows (scrolling), or from windows, which all require
somewhat different handling.
2) Support 256-color mode. This has long been very broken, now it
works more or less OK. Keep the logical palette for each colormap
as small as possible while allocating and freeing colors. Select
and realize the logical palette associated with a GdkColormap into
a DC before drawing or blitting.
When the display is in 256-color mode, make it possible for the
user to override the size of the palette(s) used with either the
GDK_WIN32_MAX_COLORS environment variable, or a -max-colors
command line option. It is possible to reduce the palette size all
the way down to using just the 16 static colors (which causes the
system visual to be of type GDK_VISUAL_STATIC_COLOR. This could
possibly be useful if one desperately wants to avoid color
flashing. (Note that in order for this to work properly, an as of
yet not commited fix to gdkrgb.c is needed.)
Handle the palette messages. On WM_PALETTECHANGED, call
UpdateColors() for the given window hierarchy. Do this only if a
window in some other top-level window hierarchy caused the palette
change (realized a palette). Do this max five times in a row (an
arbitrarily chosen limit), though, otherwise redraw by generating
expose events. On WM_QUERYNEWPALETTE, cause a redraw of the whole
window hierarchy by generating GDK_EXPOSE events.
3) Code cleanup in general. For instance, remove the "emulated"
X11 structs ColormapStruct, Visual and XStandardColormap. Use the
new GDK_DEBUG_* flags for debugging output in the relevant source
files. Remove the unused colormap hash table in gdkcolor-win32.c
4) Plug some resource leaks.
2002-02-14 Tor Lillqvist <tml@iki.fi>
* gdk/win32/gdkdnd-win32.c (gdk_dropfiles_filter): Use
g_filename_to_uri() to actually create legal URIs in the
text/uri-list data.

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.

2002-02-17 Tor Lillqvist <tml@iki.fi>
* gdk/win32/*.c: Massive changes. Too many to list here, but I'll
try a summary:
1) Unify GdkPixmap and GdkImage implementation: For each
GdkPixmap, allocate a GdkImage, and vice versa.
GdkPixmapImplWin32Data has a pointer to the GdkImage.
GdkImage::windowing_data is a pointer to the GdkPixmap.
This simplifies many pixmap and image related functions a lot, and
reduces duplicated code snippets. For instance, there is only one
place in gdk/win32 where CreateDIBSection() is called, in the
function _gdk_win32_new_pixmap(). Converting a bitmap (GdkPixmap)
to a Windows region is almost trivial, with the bitmap bits being
readily accessible in the associated GdkImage.
All blitting between GdkPixmaps, GdkWindows and GdkImages goes
through handled the _gdk_win32_blit() function, which calls
different functions to handle the cases of blitting from pixmaps,
inside windows (scrolling), or from windows, which all require
somewhat different handling.
2) Support 256-color mode. This has long been very broken, now it
works more or less OK. Keep the logical palette for each colormap
as small as possible while allocating and freeing colors. Select
and realize the logical palette associated with a GdkColormap into
a DC before drawing or blitting.
When the display is in 256-color mode, make it possible for the
user to override the size of the palette(s) used with either the
GDK_WIN32_MAX_COLORS environment variable, or a -max-colors
command line option. It is possible to reduce the palette size all

system visual to be of type GDK_VISUAL_STATIC_COLOR. This could
possibly be useful if one desperately wants to avoid color

yet not commited fix to gdkrgb.c is needed.)
Handle the palette messages. On WM_PALETTECHANGED, call
UpdateColors() for the given window hierarchy. Do this only if a

change (realized a palette). Do this max five times in a row (an
arbitrarily chosen limit), though, otherwise redraw by generating

3) Code cleanup in general. For instance, remove the "emulated"
X11 structs ColormapStruct, Visual and XStandardColormap. Use the
new GDK_DEBUG_* flags for debugging output in the relevant source
files. Remove the unused colormap hash table in gdkcolor-win32.c
4) Plug some resource leaks.

* 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.

Massive changes. Too many to list here, but I'll try a summary:

* gdk/win32/*.c: Massive changes. Too many to list here, but I'll
try a summary:
1) Unify GdkPixmap and GdkImage implementation: For each
GdkPixmap, allocate a GdkImage, and vice versa.
GdkPixmapImplWin32Data has a pointer to the GdkImage.
GdkImage::windowing_data is a pointer to the GdkPixmap.
This simplifies many pixmap and image related functions a lot, and
reduces duplicated code snippets. For instance, there is only one
place in gdk/win32 where CreateDIBSection() is called, in the
function _gdk_win32_new_pixmap(). Converting a bitmap (GdkPixmap)
to a Windows region is almost trivial, with the bitmap bits being
readily accessible in the associated GdkImage.
All blitting between GdkPixmaps, GdkWindows and GdkImages goes
through handled the _gdk_win32_blit() function, which calls
different functions to handle the cases of blitting from pixmaps,
inside windows (scrolling), or from windows, which all require
somewhat different handling.
2) Support 256-color mode. This has long been very broken, now it
works more or less OK. Keep the logical palette for each colormap
as small as possible while allocating and freeing colors. Select
and realize the logical palette associated with a GdkColormap into
a DC before drawing or blitting.
When the display is in 256-color mode, make it possible for the
user to override the size of the palette(s) used with either the
GDK_WIN32_MAX_COLORS environment variable, or a -max-colors
command line option. It is possible to reduce the palette size all
the way down to using just the 16 static colors (which causes the
system visual to be of type GDK_VISUAL_STATIC_COLOR. This could
possibly be useful if one desperately wants to avoid color
flashing. (Note that in order for this to work properly, an as of
yet not commited fix to gdkrgb.c is needed.)
Handle the palette messages. On WM_PALETTECHANGED, call
UpdateColors() for the given window hierarchy. Do this only if a
window in some other top-level window hierarchy caused the palette
change (realized a palette). Do this max five times in a row (an
arbitrarily chosen limit), though, otherwise redraw by generating
expose events. On WM_QUERYNEWPALETTE, cause a redraw of the whole
window hierarchy by generating GDK_EXPOSE events.
3) Code cleanup in general. For instance, remove the "emulated"
X11 structs ColormapStruct, Visual and XStandardColormap. Use the
new GDK_DEBUG_* flags for debugging output in the relevant source
files. Remove the unused colormap hash table in gdkcolor-win32.c
4) Plug some resource leaks.

* gdk/win32/gdkdnd-win32.c (gdk_dropfiles_filter): Use
g_filename_to_uri() to actually create legal URIs in the
text/uri-list data.
