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/gdkinput-win32.h Drop the GdkEvent* parameter, it wasn't used.
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.

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/gdkglobals-win32.c
* gdk/win32/gdkmain-win32.c
* 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/win32/gdkprivate-win32.h New flags _gdk_input_locale_is_ime and
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.

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

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
