We only want to send grab-notify to widgets that might have been
interacting with devices via events. Instead of going through all
widgets in all toplevels, we have the window/pointer focus information,
so we can just traverse the widget stacks for every involved foci.
Move away from grab_notify, and use the set_child_focus() vfunc to track
child widgets being set the keyboard focus. This is not 1:1, but seems
good enough at the moment.
While it's worth thinking about bringing the "windows can be dragged
with open popovers" behavior back, this does not kick in anymore, nor
should be the way to handle this given all the autoclose surface
semantic changes.
This kind of transient state sets the expectative that events update
devices, while it's more accurate to say that devices generate events.
It does not make to expose this function anymore.
This got stuck in ancient times when widgets were windowed, so the devices
in a window to know the devices in that widget would pan out. We do only
want here the devices that are inside the widget, not spread over the
surface, so rewrite this helper function to poke the toplevel foci, and
look they are contained inside the widget.
Crossing events are now detached from widget state, all tricky consequences
from getting multiple crossing events are now somewhat moot. Resort to sending
all generated crossing events, and drop this barely (ever?) used API.
When a gesture (group) claims a sequence, all other gesture groups
in the same widget should get cancelled. Not just previously claimed
ones, that shouldn't happen actually.
This is a list model holding strings, initialized
from a char **. String lists are buildable as well,
and that replaces the buildable support in GktDropDowns.
These sources are using GtkListStore apis,
but were replying on indirect includes to
get the header. Make this explicit, to prepare
for GtkEntryCompletion losing its tree view
dependencies.
Commit a0f6ff101e made sure that a
context was bound before calling glClientWaitSync, but it doesn't
check that the context shares objects with the context that created
the fence.
This commit does a little more validation before deciding the current
context is good enough.
Since commit 972134abe4 we now call
glClientWaitSync for the vendor nvidia driver, to know when a frame
is ready for the compositor to process.
glClientWaitSync can be called regardless of which context is currently
bound, but if no context is bound at all, it returns 0 without
doing anything.
This commit checks for that edge case, and ensures a context gets
made current in the event no context is already current, before calling
glClientWaitSync.
This api has not really been kept up with current
user experiences in popups, and we're better off
just dropping it and letting people do their own
popups if they need custom UI.
Use gtk_widget_prepend_controller to supersede entry keynav
while the popup is open. This fixes selecting completions
with the keyboard - the Enter keypress was ending up
triggering GtkText::activate instead of inserting the
selected completion into the entry.
Add a variant of gtk_widget_add_controller that
inserts the controller at the beginning, instead
of the end. This will be used in entry completion
to make sure the entry completion key event handling
supersedes the entry one while the popup is open.
Keep this private for now, until we determine if
it needs to be public api.
We were adding event controllers at the end, but
announcing a change at the beginning, in
gtk_widget_add_controller. Fix that by emitting
::items-changed for the position where we actually
inserted the controller.
When given a 0 timeout, glClientWaitSync is only supposed to return one
of three possible values:
- GL_ALREADY_SIGNALED - fence fired
- GL_WAIT_FAILED - there was an error
- GL_TIMEOUT_EXPIRED - fence hasn't fired yet
In addition, it can also return GL_CONDITION_SATISFIED if a non-zero
timeout is passed, and the fence fires while waiting on the timeout.
Since commit 972134abe4 we now call
glClientWaitSync (with a 0 timeout), but one user is reporting it's
returning some value that's not one of the above four.
This commit changes the g_assert to a g_error so we can see what
value is getting returned.
