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.
This property doesn't carry any new information compared
to GtkWindow:focus-widget. We still keep the gtk_widget_is_focus
getter, as a convenient shortcut.
Make gtk_window_set_focus call gtk_widget_grab_focus internally.
This means that set_focus can now end up putting the focus on
a child of the passed-in widget, and makes the focus-widget
property work for setting initial focus to (the child of) an
entry in a ui file.
After the header widget was introduced, focus would get
stuck in a loop between actions and tabs.
This could be seen in the notebook on page 3 of
widget-factory.
