We don't really have an event anywhere close in most
cases, and we already pass GDK_CURRENT_TIME in half
the cases anyway.
If we want to be serious about this, we need to pass
the event itself, since future focus-stealing protocols
may not rely on just a timestamp.
We need to unset the propagation limit on the focus
controller, else we miss the focus-in when the focus
enters the popover upon initial popup, when it comes
from the parent button.
Add a .link style class on labels that contain links,
so we can avoid the focus outline around the label
when individual links are focused, and use the link
node when rendering the focus on links.
Make GtkScaleButton a widget that has a toggle button
as a child, just like all the other button widgets now.
The immediate benefit of this arrangement is to avoid
the "double focus" problem when we pop up the popup.
Update accessible, demos and tests to match.
The :can-focus property is no longer very useful to
give an indication of what is focusable, since it is
TRUE for almost all widgets now. Patch things up
to by looking at known widget types.
The color editor shows a color picker button only if it
finds a suitable implementation, which it does not in ci.
So disable the focus-chain test for page 3.
This is one of the situations, where can-focus can still
be used to tweak focus behavior of leaf widgets. Color
swatches are focusable by default to allow selecting colors
with the keyboard. But when used as color samples, they
should not take focus.
This test was expecting to make existing widgets like
GtkBox focusable by setting :can-focus. That just doesn't
work anymore.
The focus chain testing that is done here is already
better covered by test-focus-chain, so lets just remove this.
The notebook grab_focus change in the previous commit made
backwards tabbing work as expected, and thereby changed the
output of one of the focus-chain tests.
After the :can-focus change in the previous commit, widgets
need to set suitable focus and grab_focus implementations
to implement the desired focus behavior.
This commit does that for all widgets.
Make widgets can-focus by default, and change the semantics
of can-focus to be recursive . If it is set to FALSE, focus
can not enter the widget or its descendents at all anymore.
This commit temporarily breaks focus behavior of widgets
that did not expect to receive focus.
The only place where this should be set is when making
a widget the focus-widget of a window. We still keep
the property around in readonly form, since there are
a few places where we rely on property notification
for it.
