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.

gdk/win32/gdkprivate-win32.h Rename all global variables and functions to
2002-11-12 Tor Lillqvist <tml@iki.fi>
* gdk/win32/gdkprivate-win32.h
* gdk/win32/*.c: Rename all global variables and functions to
start with underscore.
Merge from stable:
More work on the Win32 backend. The cause of some scrolling
problems was that SetWindowPos() and ScrollWindowEx() don't blit
those parts of the window they think are invalid. As we didn't
keep Windows's update region in synch with GDK's, Windows thought
those areas that in fact had been updated were invalid. Calling
ValidateRgn() in _gdk_windowing_window_queue_antiexpose() seems to
be an elegant and efficient solution, removing from Windows's
update region those areas we are about to repaint proactively.
In some cases garbage leftover values were used for the clip
origin in GdkGCWin32. This showed up as odd blank areas around the
pixmaps included in the Text Widget in gtk-demo.
Having the clip region either as a GdkRegion or a HRGN in
GdkGCWin32 was unnecessary, it's better to just use a HRGN.
The translation and antiexpose queue handling in
gdkgeometry-win32.c seems unnecessary (and not implementable in
the same way as on X11 anyway, no serial numbers) on Windows,
ifdeffed out.
Don't (try to) do guffaw scrolling as there is no static window
gravity on Windows. Guffaw scrolling would be unnecessary anyway,
as there is the ScrollWindow() API. This improves the behaviour of
the Text Widget demo in gtk-demo a lot. But I have no idea how the
lack of static win gravity should be handled in other places where
the X11 code uses it. Especially _gdk_window_move_resize_child().
There is still some problem in expose handling. By moving an
obscuring window back and forth over testgtk's main window, for
instance, every now and then you typically get narrow vertical or
horizontal strips of pixels that haven't been properly redrawn
after being exposed. A fencepost error somewhere?
Otherwise, all of testgtk and gtk-demo except "big windows" now
seem to work pretty well.
Bug #79720 should be fixed now.
* gdk/win32/gdkcolor-win32.c (gdk_win32_color_to_string,
gdk_win32_print_paletteentries, gdk_win32_print_system_palette,
gdk_win32_print_hpalette)
* gdk/win32/gdkdrawable-win32.c (gdk_win32_drawable_description)
* gdk/win32/gdkevents-win32.c (gdk_win32_message_name):
Move all debugging helper functions to gdkmain-win32.c.
* gdk/win32/gdkdrawable-win32.c (_gdk_win32_draw_tiles):
Rewrite. Make static. Must take tile origin parameters, too.
(gdk_win32_draw_rectangle): Pass the tile/stipple origin to
_gdk_win32_draw_tiles(). Remove #if 0 code.
(blit_inside_window): Don't call ScrollDC(), that didn't work at
all like I thought. A simple call to BitBlt() is enough.
* gdk/win32/gdkevents-win32.c (gdk_event_translate) Remove unused
latin_locale_loaded variable.
(_gdk_win32_get_next_tick): New function. Used to make sure
timestamps of events are always increasing, both in events
generated from the window procedure and in events gotten via
PeekMessage(). Not sure whether this is actually useful, but it
seemed as a good idea.
(real_window_procedure): Don't use a local GdkEventPrivate
variable. Don't attempt any compression of configure or expose
events here, handled elsewhere.
(erase_background): Accumulate window offsets when traversing up
the parent chain for GDK_PARENT_RELATIVE_BG, in order to get
correct alignment of background pixmaps. Don't fill with
BLACK_BRUSH if GDK_NO_BG.
(gdk_event_get_graphics_expose): A bit more verbose debugging output.
(gdk_event_translate): Use _gdk_win32_get_next_tick(). In the
WM_PAINT handler, don't check for empty update rect. When we get a
WM_PAINT, the update region isn't empty. And if it for some
strange reason is, that will be handled later anyway. Call
GetUpdateRgn() before calling BeginPaint() and EndPaint() (which
empty the update region).
* gdk/win32/gdkdnd-win32.c
* gdk/win32/gdkinput-win32.c:
Use _gdk_win32_get_next_tick().
* gdk/win32/gdkfont-win32.c: Use %p to print HFONTs.
(gdk_text_size): Remove, unused.
* gdk/win32/gdkgc-win32.c: Set clip origins to zero
when appropriate.
(gdk_gc_copy): Increase refcount on colormap if present.
(gdk_win32_hdc_get): Handle just hcliprgn. If we have a stipple,
combine it with clip region after selecting into the DC.
(_gdk_win32_bitmap_to_hrgn): Rename from _gdk_win32_bitmap_to_region.
(_gdk_win3_gdkregion_to_hrgn): New function, code snippet
extracted from gdk_win32_hdc_get().
* gdk/win32/gdkgeometry-win32.c: Ifdef out the translate_queue
handling.
(gdk_window_copy_area_scroll): Increase clipRect to avoid
ScrollWindowEx() not scrolling pixels it thinks are invalid.
Scroll also children with the ScrollWindowEx() call. No need to
call gdk_window_move() on the children.
(gdk_window_scroll): Don't do guffaw scrolling.
(gdk_window_compute_position): Fix typo, used win32_y where x was
intended.
(gdk_window_premove, gdk_window_postmove,
gdk_window_clip_changed): Add debugging output.
(_gdk_windowing_window_queue_antiexpose): Just call ValidateRgn()
on the region.
(_gdk_window_process_expose): No use for the serial number
parameter now. Instead of a rectangle, take a region parameter, as
Windows gives us one in WM_PAINT.
* gdk/win32/gdkmain-win32.c (_gdk_win32_lbstyle_to_string,
_gdk_win32_pstype_to_string, _gdk_win32_psstyle_to_string,
_gdk_win32_psendcap_to_string, _gdk_win32_psjoin_to_string,
_gdk_win32_rect_to_string, _gdk_win32_gdkrectangle_to_string,
_gdk_win32_gdkregion_to_string): New debugging functions.
(static_printf): Helper function for the above. sprintfs into a
static circular buffer, return value should be used "soon".
* gdk/win32/gdkwindow-win32.c (gdk_propagate_shapes): Plug memory
leak, free list after use.
(gdk_window_gravity_works): Remove, we know that there is no such
thing on Windows.
(gdk_window_set_static_bit_gravity,
gdk_window_set_static_win_gravity): Ditto, remove, they didn't do
anything anyway.
(_gdk_windowing_window_init, gdk_window_foreign_new): Call
_gdk_window_init_position() like in the X11 backend.
(gdk_window_reparent): Don't call the now nonexistent
gdk_window_set_static_win_gravity(). No idea what should be done
instead.
(gdk_window_get_geometry): The returned x and y should be relative
to parent. Used to be always zero..
(gdk_window_set_static_gravities): Return FALSE if trying to set
static gravity.
* gdk/win32/gdkprivate-win32.h: Drop the clip_region field from
GdkGCWin32. Only use the HRGN hcliprgn. Declare new
functions.
* gdk/win32/*.c: Use new debugging functions.
* gdk/win32/rc/gdk.rc.in: Update copyright year.

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.

Implement the functions that until now just were non-functional stubs. For
2002-02-26 Tor Lillqvist <tml@iki.fi>
* gdk/win32/gdkkeys-win32.c: Implement the functions that until
now just were non-functional stubs. For "hardware keycodes", we
use Windows virtual keycodes. Not scancodes, although that at
first might seem more low-level and a better match to X11
keycodes.
The Windows API is really mixed up and confused with respect to
scancodes and virtual keycodes. (Surprised?) Some scancodes are
generated by two keys on the keyboard (!), and although the
keyboard messages do have a flag to indicate which key the user
pressed, other API that take a scan code as input don't let you
specify which actual key you mean.
(update_keymap): Function to build a X11-like representation of
the keyboard. Each key has four keysyms: two levels (nonshifted
and shifted) and two groups (normal and with AltGr).
(gdk_keymap_get_direction): Use the codepage corresponding to the
thread's input locale, not the system codepage.

* gdk/win32/gdkprivate-win32.h
* gdk/win32/gdkwindow-win32.h
* gdk/win32/gdkwindow-win32.c: Remove the input_locale and
charset_info fields from GdkWindowImplWin32. Input locale is
per-thread in Windows, and as GDK on Windows really only works
when the GDI interaction all happens in just one thread anyway,
this state can be global. Use globals _gdk_input_locale and
_gdk_input_codepage instead. Set these based on the thread's input
locale (keyboard layout, or which IME is active).
* gdk/win32/gdkevents-win32.c: Set the group and hardware_keycode
fields in GDK key events. On input locale change messages, set
the global state variables, and inform update_keymap() that it
has to rebuild the keymap.

GDK W32: Test for IME correctly
ImmIsIME() doesn't work (always returns TRUE) since Vista.
Use ITfActiveLanguageProfileNotifySink to detect TSF changes,
which are equal to IME changes for us.
Also make sure that IMMultiContext re-loads the IM when keyboard layout
changes, otherwise there's a subtle bug that could happen:
* Run GTK application with non-IME layout (US, for example)
* Focus on an editable widget (GtkEntry, for example)
* IM Context is initialized to use the simple IM
* Switch to an IME layout (such as Korean)
* Start typing
* Since IME module is not loaded yet, keypresses are handled
by a default MS IME handler
* Once IME commits a character, GDK will get a WM_KEYDOWN,
which will trigger a GdkKeyEvent, which will be handled by
an event filter in IM Context, which will finally re-evaluate
its status and load IME, and only after that GTK will get
to handle IME by itself - but by that point input would
already be broken.
To avoid this we can emit a dummy event (with Void keyval),
which will cause IM Context to load the appropriate module
immediately.
