EventControllerFocus

gtk.event_controller_focus.EventControllerFocus is an event controller to keep track of keyboard focus.

The event controller offers gtk.event_controller_focus.EventControllerFocus.enter and gtk.event_controller_focus.EventControllerFocus.leave signals, as well as property@Gtk.EventControllerFocus:is-focus and property@Gtk.EventControllerFocus:contains-focus properties which are updated to reflect focus changes inside the widget hierarchy that is rooted at the controllers widget.

class EventControllerFocus : EventController {

this(void* ptr, Flag!"Take" take);

static GType getGType();

GType gType [@property getter];

EventControllerFocus self();

bool containsFocus();

bool isFocus();

ulong connectEnter(T callback, Flag!"After" after);

ulong connectLeave(T callback, Flag!"After" after);

}
