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.
If we get a nonlinear enter/leave notify on the toplevel we need
to set nonlinear in all the events we send, even if the in-toplevel
tree is linear.
This fixes combobox menus popping down immediately when you click
(not hold). (bug #587559)
We really need to wait for the MapNotify from the xserver to ensure
that the window has been mapped, as it may be delayed by the WM, network
or similar things.
This fixes a problem in the /ui-tests/keys-events gtk test
This is more important in the client side windows world, as clip masks
may be used for clipping to non-native subwindows. This fixes a bug
in aisleriot where it uses masked pixbuf drawing and it ends up drawing
over the moving card subwindow.
Turns out pygtk build broke due to the argument addition to draw_drawable.
So, we now add a new vfunc for the new draw_drawable and are thus
backwards compat.
we now use gdk_offscreen_window_set_embedder() instead of a signal
to get the parent. This also replaces set_has_offscreen_changes.
Rename "parent" in all embedding related names to "embedder" to make it
more obviously different than the normal parent.
Rename gdk_window_get_offscreen_pixmap to gdk_offscreen_window_get_pixmap
to match the other offscreen calls.
Rename gdk_window_offscreen_children_changed to gdk_window_geometry_changed
as this is more descriptive.
We emulate visibility by unmapping (in X) all mapped (according to
gdk) windows that are not visible (all parents mapped). This is because
there may be client side windows inbetween the native windows in the
hierarchy, so you can't know a native window is visible just because
all the parent native windows are mapped.
However, we don't want to unmap foreign windows, as that may cause all
sort of unexpected issues. This should be safe, because generally the
parent of a foreign window is a native window (e.g. a socket), so its
gdk visibility state is the same as the Xserver one.
This fixes an issue with the GDM notification area where the unmap of
the plug caused spurious UnmapNotify events that confused GtkSocket and
caused icons to become one pixel wide.
Last commit was bad, as it didn't clip against client side
children. This implements such clipping first and then
only clears the rectangles that need to be cleared.
This is how cairo works with native children.
This fixes an issue where the drag target outline is visible on the
evolution folder treeview when it isn't with native windows.
Without this we can't draw to them, which caused problems for e.g.
gnome-settings-daemon clearing the background when the desktop
background changed.
Note: We don't actually clip away child windows from the root window,
the clip is just based on the size of the root window.
Use g_*gettext functions in gdk-pixbuf instead direct gettext
calls to benefit from the maybe-dont-translate functionality
in GLib. Also, replace a hand-rolled version by g_dpgettext2
in gtkbuilderparser.c. Fixes bug 585791.
In the destroyed window case in do_synthesize_crossing_event we didn't
return a value which can cause infinite "loops". Always return FALSE
to make sure the idle doesn't run again.
Doing this directly had some issues with picking going recursive in
clutter-gtk. Furthermore, doing it in an idle means we can coalesce
multiple calls (which is common due to widget changes) in the same
toplevel to just one call.
You can call this if you have offscreen children and the geometry of
them changed. This will cause re-picking of the active window sending
enter and leave events as needed.
We want to be able to map any window coordinate to a root coordinate, not
just the origin, because you can't rely anymore on a simple translation
from window coordinates to parent with offscreen windows. This lets
us e.g. pop up menus in the right place even if they are popped up from
a no-window widget.
We use the offscreen signals for getting parent, picking
children at a point and mapping coordinates between windows
embedding offscreens and offscreens.
This means we have two hierarchies more or less, one visible to apps via
the standard APIs and for drawing where the offscreens are their own
separate toplevels, and another one for event handling where embedded
offscreens appear as if they were children of the embedding window.
3 signals are for offscreen windows
get-offscreen-parent: Get the parent window an offscreen is embedded in
to-parent: Convert coordinates from offscreen to parent
from-parent: Convert coordinates from parent to offscreen
1 signal is for the window embedding offscreens:
pick-offscreen-child: This picks what (if any) offscreen is at a specific position
The last signal is only used if you call gdk_window_set_has_offscreen_children
to tell gdk that the window has embedded offscreen children.
Add get-pointer signal for offscreen window pointer getting
Apps using offscreen windows can connect to get-pointer on offscreen
windows in order to make gdk_window_get_pointer() return correct
values.
Add get-offscreen-parent signal
Add signals for from-parent and to-parent coordinate mapping
Add pick-offscreen-child signal
We returned the innermost child that has the pointer, which is not right.
Only the direct child that has the pointer in it should be reported (if any).
