When we are in the the event translation function sometimes we need to
synthesise events: the double and triple click events are synthetic events
placed on the queue after a sequence of events has been received, for
instance.
Until now, the events were placed on the queue after the translation from
the native events was successful. This led to a loss of ordering because
we put the synthesised event on the queue before the last event that
triggered it.
This patch puts the events on the queue before translating them, with a
"pending" flag set; if the translation sequence is completed then the flag
is removed - otherwise the event is removed from the queue altogether. The
queue manipulation functions have been modified to ignore the "pending"
flag when looking for events.
This patch also adds a private structure overlayed on the ClutterEvent
struct so that we can extend the events with private data without exposing
it in the public API.
* clutter/eglnative/clutter-backend-egl.c:
* clutter/eglx/clutter-backend-egl.c:
* clutter/sdl/clutter-backend-sdl.c: Set the default resolution
as 96.0 dpi for every backend (we already were under this
assumption anyway, and this makes it easier to change this
setting per-backend).
* clutter/pango/pangoclutter-fontmap.c:
* clutter/pango/pangoclutter.h: Allow setting the resolution
for the PangoClutterFontMap object and provide the implementation
for the PangoFcFontMap::get_resolution() virtual function. This
allows to set the resolution of the PangoContext when retrieving
it.
* clutter/clutter-label.c (clutter_label_init): Set the
resolution of the font map with the one the backend gives us.
* clutter/clutter-entry.c (clutter_entry_init): Ditto.
* clutter/clutter-feature.h:
Add new stage feature flags and document.
* clutter/eglnative/clutter-backend-egl.c:
* clutter/eglx/clutter-backend-egl.c:
* clutter/sdl/clutter-backend-sdl.c:
Set new feature flags.
* clutter/glx/clutter-backend-glx.c:
* clutter/glx/clutter-stage-glx.c:
* clutter/clutter-stage.c:
* clutter/clutter-stage.h:
Add a 'user_resizeable' setting to the backend and implement
for glx backend.
* clutter/eglx/clutter-backend-egl.c:
* clutter/eglnative/clutter-backend-egl.c:
* clutter/sdl/clutter-backend-sdl.c: Destroy the stage in every
backend.
* TODO:
Sync up a little.
* clutter/clutter-main.c:
Set a default window title based on g_prgname().
* clutter/clutter-stage.c:
* clutter/clutter-stage.h:
* clutter/egl/clutter-stage-egl.c:
* clutter/glx/clutter-stage-glx.c:
* clutter/sdl/clutter-stage-sdl.c:
Alter draw_to_pixbuf to return a pixbuf
* configure.ac:
Only full in gdk-pixbuf-xlib as a GLX backend dep.
* tests/test-entry.c:
Fix a couple of warnings.
* clutter/sdl/clutter-event-sdl.c:
Seemingly fix SDL Event source.
Add some very basic SDL keysym translation.
(Thanks to Thomas Van Machelen for initial translation code)
* tests/test-events.c:
Dump some info on keysyms pressed.
* clutter/clutter-backend.c:
* clutter/clutter-backend.h:
* clutter/glx/clutter-stage-glx.c:
* clutter/glx/clutter-backend-glx.c:
Fix up rendering pipeline removing clutter_backend_XXX_stage_paint
and adding clutter_backend_XXX_redraw instead. Duplicates less
code in backends, avoids clutter_actor_paint() getting called
before stage is set up (viewport wise) and unbreaks things like
picking.
* clutter/clutter-actor.c:
* clutter/clutter-actor.h:
* clutter/clutter-main.c:
* clutter/clutter-private.h:
* clutter/clutter-stage.c: (clutter_stage_get_actor_at_pos):
Redo picking functionality a different way (via color indexing)
as to provide more flexibility, possibly speed and more likely
work with GL/ES (doesn't currently however - not sure why).
* clutter/clutter-group.c:
Add groups own 'pick' method.
* clutter/cogl/cogl.h:
* clutter/cogl/gl/cogl.c:
* clutter/cogl/gles/cogl.c:
Move clipping funtionality into cogl.
* clutter/cogl/gles/cogl-defines.h:
Hack around missing BGR format in GL/ES.
* clutter/egl/clutter-backend-egl.c:
* clutter/egl/clutter-backend-egl.h:
* clutter/egl/clutter-stage-egl.c:
* clutter/sdl/clutter-backend-sdl.c:
* clutter/sdl/clutter-backend-sdl.h:
* clutter/sdl/clutter-event-sdl.c:
* clutter/sdl/clutter-stage-sdl.c:
Update backends to newer API.
Add basic mouse event translation to SDL.
* clutter/Makefile.am:
* clutter/clutter-stage.c:
* clutter/sdl/Makefile.am:
* clutter/sdl/clutter-backend-sdl.c:
* clutter/sdl/clutter-backend-sdl.h:
* clutter/sdl/clutter-event-sdl.c:
* clutter/sdl/clutter-sdl.h:
* clutter/sdl/clutter-stage-sdl.c:
* clutter/sdl/clutter-stage-sdl.h:
* configure.ac:
Add a basic SDL based backend. Lacks real input event handling
(translation) as yet.
Also allows for clutter to be built against dgles.
