The race we were experiencing in the X11 backends is apparently
back after the fix in commit 00a3c698.
This time, just delaying the setting of the SYNC_MATRICES flag
is not enough, so we can resume the use of a STAGE_IN_RESIZE
private flag.
This should also fix bug:
http://bugzilla.openedhand.com/show_bug.cgi?id=1668
The input device API is split halfway thorugh the backends in a very
weird way. The data structures are private, as they should, but most
of the information should be available in the main API since it's
generic enough.
The device type enumeration, for instance, should be common across
every backend; the accessors for device type and id should live in the
core API. The internal API should always use ClutterInputDevice and
not the private X11 implementation when dealing with public structures
like ClutterEvent.
By adding accessors for the device type and id, and by moving the
device type enumeration into the core API we can cut down the amount
of symbols private and/or visible only to the X11 backends; this way
when other backends start implementing multi-pointer support we can
share the same API across the code.
The clutter_context_get_default() function is private, but shared
across Clutter. For this reason, it should be prefixed by '_' so
that the symbol is hidden from the shared object.
The XInput support in Clutter is still using XI 1.x. This will never
work correctly, and we are all waiting for XInput 2 anyway. The changes
internally should be minimal, so we can leave everything in place, but
it's better to disable XInput support by default -- at least for the
time being.
The mapping and unmapping of the X11 stage implementation is
a bit bong. It's asynchronous, for starters, when it really
can avoid it by tracking the state internally.
The ordering of the map/unmap sequence is also broken with
respect to the resizing.
By tracking the state internally into StageX11 we can safely
remove the MapNotify and UnmapNotify X event handling.
In theory, we should use _NET_WM_STATE a lot more, and reuse
the X11 state flags for fullscreening as well.
Apparently, the XInput extension is using the same pkg-config
file ('xi') for both the 1.x and the 2.x API, so we need to
check for both the 1.x XGetExtensionVersion and the 2.x
XQueryInputVersion.
The clutter_get_current_event_time() function will return the event
timestamp coming from a Clutter event. Clutter might synthesize or
throttle events, so the function cannot be used when dealing with
backend-specific use cases.
The X11 backend is the only backend supported by Clutter that makes
use of timestamps, so it's altogether fitting that it should come
with a specific function to deal with the timestamps of the X events.
Bug 1178 - No enter / leave events on actors when pointer leaves the
stage window
The patch is mostly thanks to Johan Bilien with small modifications
based on suggestions by Owen Taylor.
The X11 backend now listens for enter and leave notifications. Leave
notifications get translated directly to a CLUTTER_LEAVE
event. Clutter can detect these special events because the source
actor is NULL in which case it sets the source actor to the last known
actor and then sets the last known actor to NULL.
Enter notifications just get translated to CLUTTER_MOTION events which
will cause Clutter to generate an enter event through the usual code
path.
When processing a motion event, we need to spin the event loop two extra
times to ensure that any enter/leave events that might have been synthesized
are pumped through (otherwise they end up being pushed down the queue and
never processed).
Since Clutter changed to using a layout scheme the handling_configure
flag no longer works because the allocate method is not invoked
immediately during the call to set_size from the ConfigureNotify
handler. However it is also no longer neccessary because the resizes
are effectively batched up until a relayout is run so it won't cause
an infinite loop of resize and notify events anyway.
Continuation of the fix in commit 00a3c69868.
Instead of using a separate flag for the resize process, just
delay the setting of the CLUTTER_ACTOR_SYNC_MATRICES flag on the
stage to the point when we receive a ConfigureNotify event from
X11.
This commit will break the stage embedding into other toolkits.
There is a race condition when we resize a stage before showing
it on X11.
The race goes like this:
- clutter_init() creates the default stage and realize it, which
will cause a 640x480 Window to be created
- call set_size(800, 600) on the stage will cause the Window to be
resized to 800x600
- call show() on the stage for the first time will cause COGL
to set up an 800 by 600 GL viewport
- the Window will be mapped, which will cause X to notify the
window manager that the Window should be resized to 800x600
- the window manager will approve the resize
- X resizes the drawable to 800x600
To fix the race, we need to defer COGL from setting up the viewport
until we receive a ConfigureNotify event and the X server has resized
the Drawable.
In order to defer the call to cogl_setup_viewport() we add a new
private flag, CLUTTER_STAGE_IN_RESIZE; the flag is checked whenever
we need to change the viewport size along with the SYNC_MATRICES
private flag. Thus, cogl_setup_viewport() will be called only if
SYNC_MATRICES is set and IN_RESIZE is not set.
Instead of returning CLUTTER_X11_FILTER_CONTINUE always from
clutter_x11_handle_event() return CLUTTER_X11_FILTER_REMOVE if
the event was on a stage and translated to a ClutterEvent.
