[ NoAccessorMethod ]
public bool contains_focus { get; }
true if focus is contained in the controllers widget.
See [property@Gtk.EventControllerFocus:is-focus] for whether the focus is in the widget itself or inside a descendent.
When handling focus events, this property is updated before [signal@Gtk.EventControllerFocus:GtkEventControllerFocus:enter
]
or [signal@Gtk.EventControllerFocus:GtkEventControllerFocus:leave
] are emitted.
