The way gdk_drag_status() may be called multiple times during the
processing of drag and drop events throughout the widget hierarchy
brings some superfluous messaging going in, esp. when it's the last
request the one we want to honor, yet we emit messaging requests on
all.
This is barely appreciable in the X11 backend, but due to the design
of the wayland protocol, quick series of changes like this it have
some self-amplificating consequences which may end up flooding the
connection.
We can delegate this to a late "commit" call, performed within GDK
event management. This way gdk_drag_status() calls may be cached
and only result in windowing messaging once per ::drag-motion or
::drag-data-received event. Emitting the final status will also
avoid spurious action changes on the compositor and the other peer.

When compressing window state events, we didn't free the discarded
event after removing it from the queue, causing us to leak it. This
commit makes sure to free the discarded event after unqueuing it.
https://bugzilla.gnome.org/show_bug.cgi?id=762468
If there are already a window state event for a given window queued
when the window state is changed, drop that event and queue a new event
with a changed_mask based on the state before last event that was queue
without compression.
https://bugzilla.gnome.org/show_bug.cgi?id=762468
Remember the last source device we're generating multiple clicks for,
just so we can bail out if the device changed. That will just reset
the counting.
https://bugzilla.gnome.org/show_bug.cgi?id=723659
And use it to handle kinetic scrolling in the GtkScrolledWindow.
However, dropping the delta check causes the X11-based kinetic
scroll to break since we don't have the stop event here. Correct handling of
xf86-input-libinput-based scroll events is still being discussed.
https://bugzilla.gnome.org/show_bug.cgi?id=756729
There's places where we don't set a seat yet, plus the places
outside GTK+ where events are created, we should warn and fall
back to the master device seat with these.
The extra reference will be held from GdkEventPrivate data, so there's
a common place to all events. Without this, events queued after devices/
capabilities disappear (eg. on TTY switch) might hold invalid pointers.
Windowing level operations on those devices (queries, grabs...) are
expected to fail at that time, but we should hold meaningful data for
the regular event handling paths.
https://bugzilla.gnome.org/show_bug.cgi?id=753185
Each gesture type has its separate GdkEvent struct, and begin/update/
end/cancel event types.
There is support for multi-finger swipe (3-4 fingers), and 2-finger
rotate/pinch gestures.
Wayland's mechanism tells us all of our new states, rather than
telling us which ones were added and removed. Add a new private
interface so that we can simply specify the new states as a
bitfield directly rather than having to compute which ones were
added and removed.
If a motion event handler (or other handler running from the flush-events
phase of the frame clock) recursed the main loop then flushing wouldn't
complete until after the recursed main loop returned, and various aspects
of the state would get out of sync.
To fix this, change flushing of the event queue to simply mark events as
ready to flush, and let normal event delivery handle the rest.
https://bugzilla.gnome.org/show_bug.cgi?id=705176
Setting event compression to false will allow inter-frame
mouse motion events to be delivered, which are necessary
for painting applications to produce smooth strokes.
https://bugzilla.gnome.org/show_bug.cgi?id=702392
A switch of device may be significant for an application, so don't
compress motion events if they are for different devices. This simple
handling isn't sufficient if we have competing event streams from
two different pointer events, but we don't expect this case to be
common.
Since events can be paused independently for each window during processing,
make _gdk_display_pause_events() count how many times it is called
and only unpause when unpause_events() is called the same number of
times.
https://bugzilla.gnome.org/show_bug.cgi?id=685460
When we have pending motion events, instead of delivering them
directly, request the new FLUSH_EVENTS phase of the frame clock.
This allows us to compress repeated motion events sent to the
same window.
In the FLUSH_EVENTS phase, which occur at priority GDK_PRIORITY_EVENTS + 1,
we deliver any pending motion events then turn off event delivery
until the end of the next frame. Turning off event delivery means
that we'll reliably paint the compressed motion events even if more
have arrived.
Add a motion-compression test case which demonstrates behavior when
an application takes too long handle motion events. It is unusable
without this patch but behaves fine with the patch.
https://bugzilla.gnome.org/show_bug.cgi?id=685460
This commit introduces GDK_TOUCH_BEGIN/UPDATE/END/CANCEL
and a separate GdkEventTouch struct that they use. This
is closer to the touch event API of other platforms and
matches the xi2 events closely, too.
Use GdkWindow instead. This requires calling
gdk_x11_window_foreign_new_for_display(), so might cause a slight
performance penalty, but is required to be portable.
When copying allocated events, also copy the source device.
When synthesizing double or triple clicks, copy the original
button press event including device information.
https://bugzilla.gnome.org/show_bug.cgi?id=639822
This commit hides the GdkDisplayManager instance and class structs,
adds vfuncs for listing displays, opening displays, and getting and
setting the default display. The X11 backend has a derived
GdkDisplayManagerX11.
The gdk_display_manager_get() function is responsible for deciding on
which of the compiled in backends to use. Currently, it consults the
GDK_BACKEND environment variable and falls back to x11.
This function may be used to know the hardware device that triggered
an event, it could resort to the master device in the few cases there's
not a direct hardware device to relate to the event (i.e.: crossing events
due to grabs)
The core pointer is sort of meaningless in a multidevice environment,
the client pointer is used instead to fake a GdkDevice on events that
don't have one.
Includes fixing all callers to use the cairo region API instead. This is
usually just replacing the function names, the only difference is
gdk_region_get_rectangles() being replaced by
cairo_region_num_rectangles() and cairo_region_get_rectangle() which
required a bit more work.
https://bugzilla.gnome.org/show_bug.cgi?id=613284
Events could be injected by third party code, which could not have a
GdkDevice set for newer GdkEvent types holding a GdkDevice. This
function will now fallback to core pointer/keyboard, plus issuing
a warning about the problem.
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.

* 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.
