Intermediate commit of work in progress on integrating the old code
for OLE2-based generic drag and drop from Arhaeopteryx Software, from
a long time ago in the GTK+ 1.3 timeframe. Does still not work and is
as before not compiled in unless OLE2_DND is defined in
gdkdnd-win32.c. (Thus, for inter-process DND, still only WM_DROPFILES
style dropping of files on GTK+ apps works.)
Related slight refactoring of other code that shouldn't change how it
works. Add more global variables for run-time constants (once
initialized) representing well-known GdkAtoms and registered Windows
clipboard formats, as they with the generic DND code will be needed in
several source files. Some improved debugging output.

Bug 573067 - Intra-app dnd of text behavior on Windows is wrong
* gdk/win32/gdkdnd-win32.c (local_send_motion) (gdk_drag_motion):
The default action should be move, not copy. Tweak how the
GdkDragAction fields in GdkDragContexts are changed. Seems to help
the problem.
Add more debugging printout for --gdk-debug=dnd to many functions.

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 132501 - Make utility window translate to tool window in win32
Implement the utility window type hint. Such windows are kept on
top of other windows. Makes GIMP's toolbox and dock windows behave
more like in GNOME under metacity. Apply the same logic also to
windows marked with the dialog window type hint, and windows that
are transient for some other window. I'll call such windows
"transient-type" below.
* gdk/win32/gdkevents-win32.c (doesnt_want_key): Drop unused
variables.
(ensure_stacking_on_unminimize)
(ensure_stacking_on_window_pos_changing)
(ensure_stacking_on_activate_app): New functions to implement the
desired stacking order. Make sure that a window that is not
transient-type stays below any transient-type windows of the
application. When activating a non-transient-type window make sure
it rises as high as possible.
(gdk_event_translate): Call above functions on
WM_WINDOWPOSCHANGING, WM_ACTIVATEAPP and on WM_SIZE when
unminimizing. Improve debugging printout.
* gdk/win32/gdkwindow-win32.c (get_effective_window_decorations):
Handle utility windows like toolbar windows.
(gdk_window_new_internal) (update_style_bits): Give utility
windows the WS_EX_TOOLWINDOW extended style.
(gdk_window_set_title): If debugging "misc" or "events", make the
handle of top-level windows show up in their title bars. Very
useful when looking at debugging output.
(gdk_window_set_keep_above) (gdk_window_set_keep_below)
(gdk_window_set_modal_hint) (gdk_window_set_skip_taskbar_hint)
(gdk_window_set_skip_pager_hint): Add and improve debugging
printout.
(gdk_window_set_type_hint): Print hint symbolically in GDK_NOTE().

Remove support for Windows 9x/ME. GTK+ hasn't worked on Win9x
since 2.6 or 2.8. It's pointless to keep the Win9x code in here as
it isn't being maintained anyway. If somebody is interested, it
can always be found in older GTK+ versions, and in CVS.

* gdk/win32/gdkmain-win32.c
* gdk/win32/gdkproperty-win32.c

and G_WIN32_HAVE_WIDECHAR_API() tests and their false (Win9x)
branches, and any variables or static functions used only by the
Win9x branches.
* gdk/win32/gdkprivate-win32.h: Remove backup definitions for
constants that aren't missing from current mingw and MSVC6
headers.
* gdk/win32/gdkmain-win32.c
* gdk/win32/gdkprivate-win32.h: Remove the _gdk_win32_gdi_failed()
function. On NT-based Windows GetLastError() returns error codes
also for failed GDI calls, so we can use _gdk_win32_api_failed()
always.

* gdk/win32/gdkwindow-win32.c: Remove unnecessary includes.
(_gdk_win32_get_adjusted_client_rect): Remove this two-line
function which was used only in one place.
(get_outer_rect): Use _gdk_win32_adjust_client_rect().
(gdk_window_set_geometry_hints): If we have identical minimum and
maximum size hints, remove the resize and maximize
decorations/functions. (#104514)
If we have a maximum size hint, remove the maximize
decoration/function but ensure the resize decoration/function is
available. Otherwise ensure both resize and maximize
decorations/functions are there.
(set_or_clear_style_bits): Factored out common code from
gdk_window_set_decorations() and gdk_window_set_functions().
Hack the window style setting once more: Only touch the window
style bits corresponding to the GdkWMDecoration or GdkWMFunction
parameter bitmasks. Hopefully this finally is the correct thing to
do. We used to clear all other bits than those that were being
set, or set all other bits than those that were being cleared.
Take into account that adding or removing decorations leaves the
window's outer size unchanged, i.e., the client area's size and
position change. This is apparently not what we want, so change
also the window's (outer) position and size appropriately so that
the client area's position and size stay constant.
gtk-demo's color selector dialog is now non-resizable like on X11
(I tested with metacity in GNOME). Torn off menus are shrinkable
vertically but have a maximum size, and are not maximizable or
minimizable, like on X11.
(gdk_window_set_decorations, gdk_window_set_functions): Let
set_or_clear_decorations() do most of the job.
* gdk/win32/gdkprivate-win32.h: Remove declaration of
_gdk_win32_get_adjusted_client_rect().

* 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.

COMPOUND_TEXT and SAVE_TARGETS in addition to UTF8_STRING.

Improve and simplify line segment rendering on Win32, especially
the implementation of GDK_CAP_NOT_LAST, and dashed lines. Fixes
bug #306396.
* gdk/win32/gdkprivate-win32.h (GdkGCWin32): Save the GdkGC's
line_style, cap_style and join_style as such in the
GdkGCWin32. Don't need to keep the pen_double_dash flag, we can
check the line_style.
* gdk/win32/gdkgc-win32.c (fixup_pen): New internal function. Sets
up the GDI pen type, style, end cap and join attributes to use
based on the pen width, GDK line style, end cap style, and join
style.
For a narrow (zero-width) GDK pen with the GDK_CAP_NOT_LAST end
cap style, which typically are used for XOR drawing where it is
essential that the last pixel is not drawn, use a GDI cosmetic
pen. Only for a cosmetic pen does GDI not draw the last pixel. I
deduced this by experimetation, the documentation is rather vague.
For other GDK pens use a geometric GDI pen. If the width is 0 or 1
and the GDK end cap style is GDK_CAP_BUTT, and the line style is
GDK_LINE_SOLID, use PS_ENDCAP_ROUND. This ensures that also
single-pixel length lines are drawn. (For sngle-pixel width lines
roundness as such is of course irrelevant.) For dashed lines, use
PS_ENDCAP_FLAT.
For wide lines use PS_ENDCAP_FLAT, _ROUND or _SQUARE,
respectively, for GDK_CAP_BUTT, GDK_CAP_ROUND and GDK_CAP_PROJECTING.
For one pixel on-off dashed lines, use PS_ALTERNATE, it seems to
work better than PS_USERSTYLE. For other dashed lines, use
PS_USERSTYLE and the dashes as set by the user (or the default
four-pixel on-off style).
(gdk_win32_gc_values_to_win32values, gdk_win32_gc_set_dashes):
Call fixup_pen() to do the pen settings after modifying some of
the GDK GC attributes that affect pens.
* gdk/win32/gdkdrawable-win32.c (render_line_horizontal,
render_line_vertical, draw_segments): Check GdkGCWin32::line_style
instead of the the removed pen_double_dash member. Don't use
PATCOPY unconditionally in the PatBlt() call, use a raster ope
code that depends on the GC function in use.
(draw_rectangle, draw_segments, draw_lines): Be more careful in
deciding when to do the manual dash rendering.
(draw_segments): Don't do any manual "last point" drawing at
all. The above changes takes care of narrow line segments being
drawn correctly in most cases, at least on NT-based Windows.

Fix for #162790, by Iwan Wong:
* gdk/win32/gdkdrawable-win32.c: Implement dashed lines
correctly. Simplify the interface to render_line_horizontal() and
render_line_vertical(). Need to draw lines "manually" also on
NT-based Windowses if we have a dash offset or are drawing
double-dashed lines.
* gdk/win32/gdkprivate-win32.h: Keep also the dash offset,
double-dash flag, and a brush for the background colour (used by
the odd dashes in the double-dash line style) in the GdkGCWin32
struct.
* gdk/win32/gdkgc-win32.c: Set up above new fields.
2004-10-31 Tor Lillqvist <tml@iki.fi>
* gdk/win32/gdkprivate-win32.h
* gdk/win32/gdkglobals-win32.c
* gdk/win32/gdkmain-win32.c: Remove _windows_version and the
IS_WIN_NT() macro.
* gdk/win32/*.c: Use G_WIN32_IS_NT_BASED() from GLib instead.
2004-09-03 Tor Lillqvist <tml@iki.fi>
* gtk-zip.sh.in: List the three theme gtkrc files separately, zip
doesn't do anything if one of the files on its command line
doesn't exist.
Handle changes of screen resolution on Win32. (#151581, reported by
Arjohn Kampman)
* gdk/win32/gdkwindow-win32.c (_gdk_windowing_window_init,
_gdk_root_window_size_init): Factor out setting the root window's
size (as the size of the union of all monitors) to a new function.
* gdk/win32/gdkdisplay-win32.c (gdk_display_open,
_gdk_monitor_init): Factor out the monitor query to a new
function.
* gdk/win32/gdkprivate-win32.h: Declare above new functions.
* gdk/win32/gdkevents-win32.c (gdk_event_translate,
handle_display_change): Handle WM_DISPLAYCHANGE by calling the
above two functions, and emitting the "size_changed" signal on our
(only) GdkScreen.
2004-08-28 Robert Ögren <gtk@roboros.com>
On Win32, do not produce tablet motion or button events while a
window is being moved or resized. (#151090, reported by Shaneyfelt)
* gdk/win32/gdkprivate-win32.h
* gdk/win32/gdkglobals-win32.c
* gdk/win32/gdkevents-win32.c: Rename the variable resizing to
_sizemove_in_progress and make it extern.
* gdk/win32/gdkinput-win32.c (_gdk_input_other_event): Ignore
motion and button events if _sizemove_in_progress is true.
2004-07-07 Tor Lillqvist <tml@iki.fi>
* gdk/win32/gdkdrawable-win32.c (gdk_win32_draw_text)
* gdk/win32/gdkfont-win32.c (gdk_text_extents)
* gdk/win32/gdkproperty-win32.c (find_common_locale,
gdk_property_change)
* gdk/win32/gdkselection-win32.c (gdk_selection_convert): Use
g_utf8_to_utf16() instead of the removed _gdk_utf8_to_ucs2() (see
below).
* gdk/win32/gdkglobals-win32.c
* gdk/win32/gdkmain-win32.c (_gdk_windowing_init)
* gdk/win3/gdkprivate-win32.h: Add a variable for the TARGETS
atom. Initialize it. Declare it. Drop the variable for the
COMPOUND_TEXT atom.
* gdk/win32/gdkim-win32.c (gdk_wcstombs): Don't return UTF-8. This
function is supposed to return the string in the locale's charset
and encoding. Use g_convert().
(gdk_mbstowcs): Similarily, don't take an UTF-8 string, but a
string in the locale's charset. Use g_convert().
(_gdk_ucs2_to_utf8, _gdk_utf8_to_wcs, _gdk_utf8_to_ucs2):
Delete. The UCS-2 functions didn't handle surrogates anyway. Use
GLib's UTF-16 functions instead. Windows uses UTF-16.
* gdk/win32/gdkprivate-win32.h: Remove declarations of the deleted
functions mentioned above.
* gdk/win32/gdkproperty-win32.c (gdk_property_change): Use CF_TEXT
also if the string is of type STRING, i.e. ISO-8859-1, and the
current codepage is 1252, and contains no C1 chars. Accept
also UTF8_STRING.
* gdk/win32/gdkselection-win32.c (_gdk_selection_property_store):
Mark as static. When storing STRING data, convert to
Latin-1. (#140537)
(gdk_selection_owner_set_for_display): Now that STRING is always
ISO-8859-1, use UTF8_STRING when sending the selection request
to ourselves.
(gdk_selection_convert): Handle also UTF8_STRING. (#140537, John
Ehresman)
(gdk_text_property_to_text_list_for_display): Make work more like
X11 version. Do obey the encoding parameter.
(gdk_string_to_compound_text_for_display,
gdk_utf8_to_compound_text_for_display): Don't even pretend
supporting COMPOUND_TEXT.
(gdk_utf8_to_string_target): Convert to ISO-8859-1, like on X11.
(sanitize_utf8): Zero-terminate string.
2004-01-25 Tor Lillqvist <tml@iki.fi>
* gdk/win32/gdkproperty-win32.c (gdk_property_delete): If the
WM_TRANSIENT_FOR property is being deleted, set the owner of the
window to the root window (i.e., effectively unset it). (#132411)
* gdk/win32/gdkprivate-win32.h
* gdk/win32/gdkglobals-win32.c
* gdk/win32/gdkmain-win32.c: Declare, define and initialize
_wm_transient_for, a GdkAtom for WM_TRANSIENT_FOR.
* acconfig.h: Remove HAVE_WINSOCK_H, not used any longer.
2003-08-07 Tor Lillqvist <tml@iki.fi>
* gdk/win32/gdkinput-win32.h
* gdk/win32/gdkinput-win32.c (_gdk_input_configure_event,
_gdk_input_enter_event): Drop the GdkEvent* parameter, it wasn't
used.
* gdk/win32/gdkevents-win32.c (gdk_event_translate): Adapt caller
accordingly, in fact an uninitialised variable was dereferenced.
[Win32] Add support for multiple monitors.
* gdk/win32/gdkprivate-win32.h
* gdk/win32/gdkglobals-win32.c: New global variables for
multiple-monitor info: _gdk_num_monitors, _gdk_monitors, and
_gdk_offset_x and _gdk_offset_y.
* gdk/win32/gdkdisplay-win32.c (count_monitor, enum_monitor): New
functions, enumeration functions passed to EnumDisplayMonitors().
(gdk_display_open): If the EnumDisplayMonitors() and
GetMonitorInfo() API is present (on Win98, Win2000 and newer), use
if to find out monitor info.
Calculate the offset between Win32 coordinates (relative to the
primary monitor's origin (and thus negative on monitors to the
left of or above it), and GDK's (visible coordinates should be
non-negative).
* gdk/win32/gdkscreen-win32 (gdk_screen_get_n_monitors,
gdk_screen_get_monitor_geometry): Use information collected above.
(gdk_window_move, gdk_window_move_resize_window_get_geometry):
Subtract _gdk_offset_{x,y} from GDK root window coordinates.
(gdk_window_get_geometry, gdk_window_get_origin,
gdk_window_get_frame_extents): For top-level windows, add
_gdk_offset_{x,y} to GDK root window coordinates
Still need to handle multiple monitors in
gdk_window_fullscreen(). Probably should make the window
fullscreen on the monitor where the cursor is?
* gdk/win32/gdkevents-win32.c: Add _gdk_offset_{x,y} to all GDK
root window coordinates in GdkEvents.
[Win32] Fix geometry hint handling. Add support for resize
increment and base size, and aspect ratio geometry hints. The
"gridded geometry" test in testgtk now works beautifully.
* gdk/win32/gdkwindow-win32.c (gdk_window_set_geometry_hints):
Turns out this function shouldn't actually ever modify the
window's size, just store the hints. (Old code kept for a while
inside #if 0.)
(gdk_window_set_hints): Remove presumably broken code that handles
the position hints, this function is obsolete anyway.
* gdk/win32/gdkevents-win32.c: Drop the current_{x,y}_root
variables, not used.
(adjust_drag): New function, used to implement resize increment
hints.
(gdk_event_translate): Handle WM_SIZING, implement resize
increment and base size, and aspect ratio geometry hints here. The
WM_GETMINMAXINFO handler takes care of the minimum and maximum
size hints as before. Fix the WM_GETMINMAXINFO handler to take
into account window decorations. No need to modify the
ptMaxPosition and ptMaxSize fields in the MINMAXINFO struct,
the defaults are fine.
* gdk/win32/gdkprivate-win32.h
* gdk/win32/gdkwindow-win32.c (_gdk_win32_adjust_client_rect,
_gdk_win32_get_adjusted_client_rect): New helper functions.
2003-07-25 Tor Lillqvist <tml@iki.fi>
* gdk/win32/gdkprivate-win32.h
* gdk/win32/gdkglobals-win32.c: New flags _gdk_input_locale_is_ime
and _gdk_keyboard_has_altgr.
* gdk/win32/gdkevents-win32.c: Lots of changes. Most important
ones detailled here.
Code that has been ifdeffed out for a long time removed. Remove
some really old doc comments that were left behind for some public
functions, the official ones are in the X11 backend anyway. Change
GDK_WINDOW_OBJECT() calls to GdkWindowObject casts. Reformat
multi-line boolean expressions to have the operators at ends of
lines.
As mouse capture with SetCapture() indeed seems to work OK, no
need to have the correspoinding macro USE_SETCAPTURE and ifdefs.
Ifdef out the gdk-ping-msg stuff. I don't remember why it was
needed at some time, and things seem to work fine now without
(knock on wood).
Ifdef out the search for some Latin locale keyboard layout being
loaded. Not used currently, but might be needed after all, if we
decide that we want to be able to generate ASCII control character
events with a non-Latin keyboard.
(assign_object): New helper function, handles the g_object_ref()
and unref() calls when assigning GObject pointers.
(generate_crossing_events): Also generate the GDK_NOTIFY_INTERIOR
enter event when the pointer has moved to an ancestor window. Was
left out by mistake.
(gdk_window_is_ancestor): Renamed from gdk_window_is_child().
(gdk_pointer_grab, gdk_pointer_ungrab): Implement the confine_to
functionality, using ClipCursor().
(find_window_for_mouse_event): Splice part of code into new
function find_real_window_for_grabbed_mouse_event().
(fixup_event, append_event, apply_filters): New functions, code
refactored out from elsewhere.
(synthesize_enter_or_leave_event, synthesize_leave_event,
synthesize_enter_event,
synthesize_leave_events,synthesize_enter_events): Also take a
GdkCrossingMode parameter, in preparation to generating
GDK_CROSSING_GRAB and GDK_CROSSING_UNGRAB events.
(fixup_event, append_event, fill_key_event_string): New functions,
code refactoring.
(vk_from_char, build_keypress_event, build_keyrelease_event):
Removed as part of dropping WM_CHAR handling.
(build_key_event_state,gdk_event_translate): Call
GetKeyboardState(), once, for each keyboard message, instead of
several calls to GetKeyState() here and there.
(gdk_event_translate): Fix bugs #104516, #104662, #115902. While
at it, do some major refactoring, and some fixes for potential
problems noticed while going through the code.
Don't handle WM_CHAR at all. Only handle WM_KEYDOWN and
WM_KEYUP. Don't need the state variables related to whether to
wait for WM_CHAR or not, and whether the current key is
AltGr. Remove lots of complexity. Thus don't need the
use_ime_composition flag.
Not handling WM_CHAR means dead key handling will have to be taken
care of by GTK, but that seems to work fine, so no worry.
Another side-effect is that Alt+keypad digits don't work any
longer, but it's better to learn to use GTK's ISO14755 support is
anyway.
Be more careful in checking whether AltGr is involved. Only
attempt to handle it if the keyboard actually has it. And
explicitly check for *left* Control plus *right* Alt being
pressed. Still, allow (left) Alt and/or (right) Control with AltGr
chars.
Handle keys using similar code as in the X11 backend. As we have
built a keymap in gdkkeys-win32.c anyway, use it by calling
gdk_keymap_translate_keyboard_state() to look up the keysym from
the virtual key code and keyboard state. Build the key event
string in exactly the same way as the X11 backend.
If an IME is being used, don't generate GDK events for keys
between receiving WM_IME_STARTCOMPOSITION and
WM_IME_ENDCOMPOSITION, as those keys are for the IME.
For WM_IME_COMPOSITION, handle all the Unicode chars returned from
the IME, not just the first one.
gdk_event_translate() is still quite complex, could split the
message handler cases out into separate functions.
On mouse events, when the mouse is grabbed, use
find_real_window_for_grabbed_mouse_event() in order to be able to
generate correct crossing events.
No longer take a pre-allocated GdkEvent as parameter. Instead,
allocate events as needed and append them to the queue. (This is
different from how gdk_event_translate() in the X11 backend
works.) This change made the code much clearer, especially in the
cases where we have to generate several GDK events for one Windows
message. Return FALSE if DefWindowProc() should be called, TRUE
if not. If DefWindowProc() should not be called, also return the
value to be returned from the window procedure.
(Previously, the interaction with gdk_event_translate()'s caller
was much more complex, when we had to indicate whether the
already-queued event should be left in the queue or removed, and
in addition also had to indicate whether to call DefWindowProc()
or not, and what value to return from the window procedure if
not.)
Don't use a separate "private" variable required to be pointing to
the GdkWindowObject of the "window" variable at all times. Just
use casts, even if looks a bit uglier.
Notice destroyed windows as early as possible, and break out of
the messsage switch.
Use _gdk_pointer_root as current_window when the pointer is
outside GDK's top-level windows.
On WM_INPUTLANGCHANGE, set _gdk_input_locale_is_ime as
appropriate, based on ImmIsIME().
(gdk_event_translate, gdk_event_send_client_message_for_display,
gdk_screen_broadcast_client_message): Implement client messages.
Use a registered Windows message to pass GDK client messages. Note
that the amount of user data is restricted to four bytes, as it is
carried in the LPARAM. (The WPARAM is used for the message type
"atom".)
(real_window_procedure): Adapt for new gdk_event_translate()
interface.
* gdk/win32/gdkmain-win32.c (_gdk_windowing_init): Set
_gdk_input_locale_is_ime initially.
* gdk/win32/gdkwindow-win32.c: Use g_object_ref()/unref() instead
of g_colormap_ref()/unref().
(gdk_window_new): Made code a bit more like the X11 one, pretend
to handle screens (although we just have one for now).
* gdk/x11/gdkevents-x11.c
(gdk_event_send_client_message_for_display,
gdk_screen_broadcast_client_message): Document the user data
limitation on Win32.
* gdk/win32/gdkevents-win32.c (print_event): More complete enter
and leave notify detail output.
* gdk/win32/gdkkeys-win32.c (update_keymap): Make dead keys
visible to GDK and GTK. Store the corresponding GDK_dead_* keysym
for those, so that the GtkIMContextCimple compose tables will
work. Deduce if the keyboard layout has the AltGr key, and set the
above flag accordingly.
