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.
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).
This also removes the (unimplemented) possibility to change a window to
non-native. This seems generally not very useful, and there are some problems
with it, for instance if two "users" need a window to be native and then
one of the "users" doesn't need it anymore it can't change it back, because
it is unaware of the other reason the window is native.
If a native window or a window with a native subwindow is moved or resized
then the client window moves and implicit paints need to be flushed since
the native window move will copy/overwrite data. This may happen while there
is an outstanding paint if the move is inside an expose event (weird, but
flash embedded in webkit hit this).
Right now we're asserting here, but the right fix is to allow this but
to not flush the parts that are currently in a (non-implicit) paint. This
means we flush all results from previous not-yet-flushed exposes, but not
the ones being drawn.
Calling gdk_window_get_events() had the side-effect of letting
property change notification through to the application, which
was not intended. Now we keep StructureNotify and PropertyNotify
filtered out when they were before. Reported in bug 582003.
After doing some performance analysis, it was found that the GTK+ mediaLib code
triggers unnecessary lazy loading of dependent libraries. The current code
uses RTLD_DEFAULT, RTLD_PROBE, RTLD_NEXT, and RTLD_SELF. However, RTLD_PROBE
is all that is necessary, and avoids triggering the lazy loading. So this
commit fixes the code to just use RTLD_PROBE. (Bug 580678)
Change gdk_window_set_icon_name to allow using NULL to unset a
previously set icon title, so that the icon title tracks the normal
title again. Bug #535557.
When RandR 1.2 X driver doesn't return any usable multihead data the
monitors array is freed, without freeing the memory allocated by the array
elements before. Fixes bug #578354
Use the same code path to get a CGContext for both gdk_draw_* and
gdk_cairo_create and make sure we unlockFocus in both cases. This
fixes the broken rendering in GtkRuler. Also use an average of flush
intervals when checking whether we can flush or not, since otherwise
we get too sensitive and block almost all explicit flushes that are
caused by mouse movements for example.
Unfortunately the old GdkWindowObject is public and accessed
from macros, etc. So, we publish a limited copy of GdkWindowObject
and use the full one internally when building gdk.
In the new world offscreen windows are not put in the hierarchy, but are
rather toplevels for themselves. Offscreen hooks don't make any sense
in this model.
It often happens that we move region A to B and then we move a subset
of B to C. When possible we'd like to replace this with a move from
A directly to C, and a suplimentary move from A to the areas of B not
overwritten by C.
Getting an optimal move combiner seems quite complicated, but this
simple approach gets most of the interesting cases right and isn't
all to complicated.
There is no need to copy something that is already invalid and will
be marked as invalid in the destination anyway, so we remove this
area from the region to copy.
The expose translation is useful for tracking how outstanding
invalid (exposed on server) areas are copied, and how we need to
compensate for that on the client side to redraw the right area.
So, we should queue the translation at the time we actually move
the bits on the server side, not when moving the window on the
client side.
Also, clean up some naming of parameters.
We now copy outstanding window moves directly on the window and
not to an intermediary pixmap, this means our previous code to
combine window copies was wrong (it relied on each copy not
destroying the source date).
Furthermore, we can't just remove all the update area from the
destination of the outstanding moves, as sometimes things get
copied into that area and then used as the source of another
copy.
We replace the previous window copy combining with a naive
version that just queues each move, just to get things right.
Further work to optimize copies is possible.
Also, we don't remove copy destinations that are used as source
for later copies.
We also clean up the memory management by not having
move_region_on_impl taking ownership of the passed in region.
Apps that set no exposure mask rely on the system clearing things
to the window background, so we need to do this ourselves.
Also, don't do this on foreign windows, as they are not controlled
by us. In fact don't do exposes on foreign windows either.
This is required for the GtkSocket code, as it shows the plug child
even though the current cached state is (wrongly) that its already
mapped.
This makes blink work for non-local case in testsocket.
Native descendants of a virtual children are not automatically destroyed
with the parent as if it was a native window, so we need to handle
the native recursion tracking manually in _gdk_window_destroy_hierarchy()
It turns out that XCopyArea handling of obscured source regions is
buggy. It clears the destination area even outside the GC clip
region. We work around this for the pixmap->window case as that
can happen in gtk+ and is easy to work around.
X Bug report at:
http://lists.freedesktop.org/archives/xorg/2009-February/043318.html
Some apps really need to set custom event masks on native child windows,
for example emacs sets the event masks with gdk, but then reads out
the raw X events via a filter, so gdk event emulation doesn't work for that.
When we get motion or button events we map back from the event position and
window to the toplevel before doing anything, because a toplevel native window
could e.g. overlap a child window or whatever.
These are generated when we get an implicit grab on a native
child window, and we can't filter them with _has_grab() because
they are sent before the button press event where we detect
the implicit grab.
This makes clicks work in the flash plugin again
It turns out we really have to ignore grab/ungrab events or we'll
report double crossing events when we grab or ungrab.
However, we also can't ignore crossing events from grabs from other clients
as that leads to missed enter/leave events on e.g. alt-tab in metacity.
Fortunately we now track grabs very precisely, so we know with certainty
whether we have a grab at the time (serial) of the native crossing events,
and only if we do we ignore them.
If we get crossing events with subwindow unexpectedly being NULL
that means there is a native subwindow that gdk doesn't know about.
We track these and forward them, with the correct virtual window
events inbetween.
This is important to get right, as metacity uses gdk for the frame
windows, but gdk doesn't know about the client windows reparented
into the frame.
For instance if we grab the pointer and then check if its grabbed
so that we know to ungrab we don't care that the grab is not
yet active, so report the steady state (i.e. the last grab)
Having GDK_WINDOW_CHILD windows with root as the parent apparently works,
and metacity uses it. The current gdk_window_get_toplevel() returns the
root window for that, which is wrong, so we check that explicitly.
This causes all sorts of weirdness with pointer_over_window
being the rootwindow and then crashing gdk_window_get_toplevel() later.
With this metacity stops crashing madly.
To avoid drawing the window background of other windows in the area
where the window was we set the bg to none recursively. However, this
is quite costly it the moved window has many siblings. Furthermore, it
is uncommon that siblings overlap, so this cost has little gain.
So, we only set bg None on the parent, which means that there will
be some more flicker in the uncommon case of overlapping siblings.
These are sent when someone else grabs the pointer, and we don't
want to miss these expose events. For instance, we missed enter
and leave events on alt-tab.
There were some issues with these wrt out-of-sync grab information
in the client, but that should now be handled. So, it should work
or at least be fixable if we find some bug.
After a successful grab/ungrab we wait for an xserver
roundtrip until we change the tracked grab in GdkDisplay.
This way that data is always up-to-date wrt events comming in.
Get rid of invalidate_maybe_recurse and process_updates. Implement
_gdk_windowing_{before,after}_process_all_updates(), and keep track of
when we're inside process_all_updates in the common code so we know
when to flush windows. Implement
_gdk_windowing_window_process_updates_recurse by means of
setNeedsDisplayInRect: displayIfNeeded. Use the added window argument
in begin_paint_region to get the right window (the paintable is always
the impl window now).
