We want to ensure that the pointer position is reflected
when widget geometry changes, so add a function that tells
GDK "please create a motion event at the current position
on this surface, if one doesn't happen already".
Handle both these settings, and the older settings-daemon ones for
backwards compatibility. The keys are already checked for existence
in the schema, so it will just use the existing ones.
Prefer this location, but also look for the old location in
settings-daemon for backwards compatibility. This applies to both
direct settings lookups and via the settings portal.
A year ago, we make this function not return the child
surface anymore. But the information whether the device
is actually over the surface is still useful, and we
should not loose it.
We are reusing the GtkCrossingData struct for multiple
calls here, so we need to make sure that the targets
stay alive from beginning to end.
Fixes: #3090
If some node is fully outside the clip region we don't send it to the daemon.
This helps a lot in how much data we send for scrolling viewports.
However, sending partial trees makes node reuse a bit more tricky. We
can't save for reuse any node that could possibly clip different depending on
the clip region, as that could be different next frame. So, unless the
node is fully contained in the current clip (and we thus know it is not
parial) we don't allow reusing that next frame.
This fixes#3086
If alpha is 255, we use rgb() instead of rgba(), not if alpha is 0.
This makes the title bar gradient go from fully transparent to blue
rather than black to blue..
By adding 20 fonts / frame to the font list, we can
get the font chooser dialog to show up much faster.
This change gets the font chooser up in 265ms here.
We cannot pass all the data we pass to the virtual function, because the
types are private, but the class and the signal are public API.
The signal is just a notification, so we can decouple the virtual
function (which stays the same, for internal types that implement the
ATContext API contract) from the signal.
If the ATContext state hasn't changed—for instance, if the accessible
attributes have been set to their default value, or have been set to the
same value—do not emit an accessible state change. State changes can be
arbitrarily expensive, so we want to ensure that they are meaningful.
Bail out early, instead of going deep into the GtkAccessibleValue type
equal() implementation, where we expect both accessible values to have
the same type.
