Since gtk+ draws more than the widget and allocates more size to it than
it knows about, this flag doesn't work anymore. Removing it (or setting
it to TRUE for widgets that used to set it to FALSE) fixes drawing
invalidation when these widgets get allocated a new size.
Since setting a clip is mandatory for almost all widgets, we can as well
change the size-allocate signature to include a out_clip parameter, just
like GtkCssGadget did. And since we now always propagate baselines, we
might as well pass that one on to size-allocate.
This way we can also make sure to transform the clip returned from
size-allocate to parent-coordinates, i.e. the same coordinate space
priv->allocation is in.
Commit b52966a318 stopped the parser from
handling various deprecated pseudoclasses, which were aliases of others,
but it did not update the documentation to reflect that they were gone.
When there is no externally allocated baseline, we should
do the same thing that GtkBox does, and determine one from
the children that want baseline alignment.
This commit adds a GtkCenterBox::baseline-position property
with setters and getters.
We now rely on toplevels receiving and forwarding all the events
the windowing should be able to handle. Event masks are no longer a
way to determine whether an event is deliverable ot a widget.
Events will always be delivered in the three captured/target/bubbled
phases, widgets can now just attach GtkEventControllers and let those
handle the events.
Those are now needless and wrong, as we get guarantees that handled
events will contain widget-relative coordinates. A side effect is
that these events are very possibly not explicitly sent to the
GdkWindow that implementations expect, any extra checks performed
through gtk_gesture_set_window() will be wrong, so the function has
been dropped entirely.
We need to reference the types file directly, because it won't be copied
into the builddir by Meson — except for GTK, which needs to generate its
own types file using configure_file().
This was only every implemented under X11, and with CSD,
this is clearly in the application realm. We should not
pretend that we can support it on the toolkit level.
