Lots of changes to the Win32 backend:
One big improvement is that scrolling of windows with background
pixmaps now works much better. (This can be seen in for instance
testgtk's "text" test.) Blitting inside a window
(gdk_draw_drawable) also works much better now (can also seen in
the "text" test).
Another major change is we 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().
Big windows still don't work correctly, I assume.
l
Another vague area is the translate_queue. I don't think the queue
items actually ever gets used, at least not in the code as of now.
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?
* gdk/win32/gdkevents-win32.c: Cast known GdkWindowObjects
directly instead of using GDK_WINDOW_OBJECT(). 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, 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/gdkgeometry-win32.c
(_gdk_windowing_window_queue_antiexpose): Always return FALSE for
now, until figured out whether antiexposes actually can work on
Win32.
(gdk_window_copy_area_scroll): 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_queue_append): Use GetTickCount() for serial number,
not GetMessageTime(), which can be very far back.
* gdk/win32/gdkwindow-win32.c (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/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/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/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): New
debugging functions.
(static_printf): Helper function for the above. sprintfs into a
static circular buffer, return value should be used "soon".
* gdk/win32/gdkgc-win32.c: Use above debugging functions.
* gdk/win32/gdkprivate-win32.h: Declare new functions, remove
obsoleted ones.
