This moves the native show/hide calls to the generic code
for calculating viewable rather than in its own separate code
called from gdk_window_show/hide. This simplifies the code a bit,
but most significantly it means things are correctly shown when
they become viewable for other reasons than a show/hide call.
For instance, this fixes bug 590442 (gvim embedding) where the
toplevel GtkPlug is mapped by the embedder and we didn't previously
pick up that the native children became viewable and should be shown.
We used to invalidate the whole window when raised, but this is
unnecessary much, we now just invalidate the visible area minus the
previously visible area.
This also fixes a problem where expose calling raise caused a loop (#588438)
This never worked before csw since the root window is never
set as IS_MAPPED, but with the new viewable check (which is
true for the root window) we could erronously queue exposes
on the root window.
This happened unexpectedly in bug 589369, where metacity
got a GraphicsExpose event on the root window due to some
graphics operation, queueing an expose which would be handled
by clearing that area. That is fixed with this commit.
This seems to more or less fix the build. On Tiger there are still issues
with libresolv missing on the link line, I will figure out what's up with
that soonish.
We get the real pixmap size and use as cairo surface size rather
than doing some magic to try to get clipping on the right hand size
(and the magic looks wrong anyway).
The previous code could result in the width/height being to big for
the cairo 28.4 fix point size and thus not drawing anything.
This fixes bug #588076.
When the fallback for gdk_draw_pixbuf (gdk_drawable_real_draw_pixbuf)
is called with a window destination we have already applied any clip
regions and offsets for the window, but the window we get is a wrapper
and not an impl. We have to ensure we really draw to the impl, as
otherwise the pixbuf drawing will be clipped by client side subwindows.
This fixes bug 588553.
gdk_window_input_shape_combine_mask() can accept NULL for the mask
parameter, but it wasn't checking for NULL before passing the
resulting GdkRegion to gdk_region_destroy(). Fixes#589275
When the region is empty we can return early, because there
is no more area to remove. This happens often for children
of scrolled windows (i.e. things that are clipped out.
Implement _gdk_win32_window_destroy() by just renaming
_gdk_windowing_window_destroy(), removed superfuous stub.
Also cleaned up implementations of gdk_win32_window_set_background()
and gdk_win32_window_set_back_pixmap() - removed stuff now done at the
respective gdk_window_*() function.
Resurrcetion and adaption of find_window_for_mouse_event(). The window
receiving the WM_MOUSEMOVE, WM_?BUTTONDOWN is not necessarily the one
interested in GDK_(ENTER|MOTION|LEAVE)_NOTIFY
http://bugzilla.gnome.org/show_bug.cgi?id=588373
Also added some more more TODO_CSW and disabled print_event(): it can not
cope with the new _gdk_windowing_got_event() eating/morphing events.
The scrolling and region moving code needs to avoid drawing when the
window is mapped, which it did. However, it also needs to avoid
drawing when any of its parents are not mapped, which it didn't so
switch to using gdk_window_is_viewable().
This fixes the index rendering in evolution (#588169)
When we ungrab the pointer we don't get enter events for the window the
pointer is in at the time of the ungrab, so we manually query for the
window the pointer is in. The same thing actually happens on re-grab if
the previous grab was !owner_events (meaning we don't get crossing events
for windows other than the grab) but the new grab is owner_events (and
thus non-grab windows need to get crossing events).
This factors out some common code and enables it also for the re-grab
to owner_events case.
