We've long had double precision mouse coordinates on wayland (e.g.
when rotating a window) but with the new scaling we even have it on
X (and, its also in Xinput2), so convert all the internal mouse/device
position getters to use doubles and add new accessors for the
public APIs that take doubles instead of ints.
This function returns all the children that has a specific user_data set.
This is used a lot in the new GtkWidget drawing code and doing
it this way is faster than getting every child and calling get_user_data
on each (which was a non-neglible part of the profiles). Additionally it
also allows use to use some kind of hashtable to make this operation even
faster if needed in the future.
This lets you register callbacks for when child widgets invalidate
areas of the window read it and/or change it.
For instance, this lets you do rendering effects and keeping offscreen
caches uptodate.
Instead of making the frame clock a settable property of a window, make
toplevel windows inherently have a frame clock when created (getting
rid of the default frame clock.) We need to create or destroy frame
clocks when reparenting a window to be a toplevel, or to not be a
toplevel, but otherwise the frame clock for a window is immutable.
Deprecate gdk_window_enable_synchronized_configure() and
gdk_window_configure_done() and make them no-ops. Implement the
handling of _NET_WM_SYNC_REQUEST in terms of the frame cycle -
we know that all processing will be finished in the next frame
cycle after the ConfigureNotify is received.
and gdk_window_get_fullscreen_mode() API to allow
applications to specify if a fullscreen window should
span across all monitors in a multi-monitor setup or
remain on the current monitor where the window is
placed.
Fullscreen mode can be either GDK_FULLSCREEN_ON_ALL_MONITORS
or GDK_FULLSCREEN_ON_CURRENT_MONITOR.

This patch changes all uses of GDK_DEPRECATED(_FOR) in gdk headers
by the versioned variants, GDK_DEPRECATED_IN_3_x(_FOR). At the same
time, we add GDK_AVAILABLE_IN_3_x annotations for all API additions
in 3.2 and 3.4.
As pointed out in bug 665999, these were just not right.
Before this commit, the nicks were 'output' and 'only'.
After this commit, they are 'input-output' and 'input-only'.
The previous function gdk_drag_get_protocol_for_display() took native
window handles, so it had to be changed. Because it didn't do what it
was named to do (it didn't return a protocol even though it was named
get_protocol) and because it doesn't operate on the display anymore but
on the actual window, it's now called gdk_window_get_drag_protocol().
Its usecase was GERD - http://testbit.eu/~timj/historic/gerd/ - and that
project is long since dead.
It has been superseded in GTK 2.2 by GdkDisplayPointerHooks anyway.
This function will enable events for all devices of a given
GdkInputSource, either these available at the time of the call,
or these that are connected in the future.
This new function takes a GdkRGBA in order to set the background to
an alpha color. Keep in mind that RGBA visuals and a composited environment
are still necessary to have an alpha background displayed.
Add signal GdkWindow::create-surface which allows to use any
surface type as storage for offscreen windows.
Test the new signal in tests/gdkoffscreenbox.c
The feature can and should be implemented manually using
gdk_window_get_background() and Cairo drawing. A non-cairo drawing API
does not make sense in GDK anymore.
Now the window background is a cairo_pattern_t. The backends will try to
set this as good as they can on the windowing system, but no guarantees
are made on wether the windowing system supports the pattern.
Also gets rid of GDK_NO_BG as undefined behavior is not a good idea to
support, and GDK_NO_BG effectively made the window's contents undefined.
It wasn't effectively used in GTK anyway.
This removes gdk_window_shape_combine_mask() and
gdk_window_input_shape_combine_mask(). GdkBitmap is going away and a
replacement exists via the combine_region() functions and
gdk_cairo_region_create_from_surface().
They were added as accessors for 2.22 even though querying the
background wasn't possible previously. As GTK 3.0 will change background
handling, it doesn't make sense at all to expose these getters.
which also works for offscreen windows and their embedder.
Also add gdk_window_get_effective_parent() and
gdk_window_get_effective_toplevel() which are offscreen aware.
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.
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.
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
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.
The history before this was kind of twisted as several different
approaches were tested, so that was all squashed into this initial
commit to hide the uninteresting changes and files that were later
removed.

* Practically everything changed.
Change all references of GIMP Toolkit (and variations of it)
to GTK+ Toolkit, showing no mercy at all to our beloved
ancestry. (#540529)

* gdk/gdk.h: define __GDK_H_INSIDE__ around including all other
headers.
* gdk/gdkenumtypes.h.template
* gdk/gdk*.h: add single-include guards that #error out if
GTK_DISABLE_SINGLE_INCLUDES is defined and any of these files is
included individually. Also removed some redundant includes and
did some tiny trailing whitespace removal that's not worth to
commit separately.
* gdk/gdkprivate.h: include <gdk/gdk.h> instead of individual
files.
* gdk/win32/gdkwin32.h
* gdk/x11/gdkx.h: only include <gdk/gdkprivate.h> and remove all
other includes.

* Applied pixmap redirection patch by Alexander Larsson with
various updates from:
Bug 318807 – Offscreen windows and window redirection.
Updates:
* updated docs to mention "Since 2.16".
* tests/testgtk.c: fixed snapshooting pixmap leak.
convert pixmap to pixbuf after snapshooting, to compensate for different
bit depths (occurs when snapshooting ARGB visuals and displaying the
pixmap in an RGB visual).
* gdk/gdkwindow.[hc]: made GdkWindowRedirect private.
* gdk/gdkwindow.c: removed damage idle handler, there's no aparent
need for it. enqueue damage notification as GDK_DAMAGE events
for each painting redirection at the start of the event queue.
consider windows with a redirection fully visible when invalidating,
and when updating from backing store. cleaned up stale variables.
* gdk/gdkevents.c: added _gdk_event_queue_prepend().
* gtk/gtkwidget.c: fixed coordinates for !NO_WINDOW widgets in
gtk_widget_get_snapshot; this fixes garbage snap offsets for gammacurve,
tree, drawingarea, text, handlebox, etc.
clip the redirected window hierarchy to window sizes, the visible
rectangles don't need to be taken into account here.
extended snapshooting docs to recommend gdk_pixbuf_get_from_drawable()
in case pixmap visuals could mismatch.
* gdk/x11/gdkwindow-x11.c: removed _gdk_windowing_window_get_visible_rect().
Base patch:
* tests/testgtk.c: add a "Snapshot" test to demonstrate snapshooting
of possibly obscured widgets into an offscreen pixmap.
* gtk/gtkwidget.[hc]: add GtkWidget::damage-event signal, add
gtk_widget_get_snapshot() to render a widget's contents to a GdkPixmap.
* gtk/gtkmain.c: dispatch GDK_DAMAGE events.
* gdk/gdkwindow.c: moved outer gdk_window_new() and gdk_window_reparent()
implementations here, adapted them to propagate redirects to child windows.
gdk_window_end_paint(): copy repainted window contents to redirection pixmap,
clipped to visible region. queue GDK_DAMAGE event delivery.
gdk_window_redirect_to_drawable(): install window painting redirection.
gdk_window_remove_redirection(): remove previously installed redirection.
* gdk/x11/gdkwindow-x11.c: added _gdk_windowing_window_get_visible_rect(),
renamed _gdk_window_new() and _gdk_window_reparent().
* gdk/gdkwindow.h: added GdkWindowRedirect* to GdkWindowObject, export
gdk_window_redirect_to_drawable() and gdk_window_remove_redirection().
* gdk/gdkevents.h: added GDK_DAMAGE event type.
* gdk/gdkevents.c: extract time and state from GDK_DAMAGE events.
* gdk/gdkinternals.h: added internal prototypes.
