EventControllerFocus

GtkEventControllerFocus is an event controller to keep track of keyboard focus.

The event controller offers [signal@Gtk.EventControllerFocus::enter] and [signal@Gtk.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 {

GtkEventControllerFocus* gtkEventControllerFocus;

GtkEventControllerFocus* getEventControllerFocusStruct(bool transferOwnership);

void* getStruct();

}

Constructors

this this(GtkEventControllerFocus* gtkEventControllerFocus, bool ownedRef): Sets our main struct and passes it to the parent class.
this this(): Creates a new event controller that will handle focus events.

Functions

addOnEnter gulong addOnEnter(void delegate(EventControllerFocus) dlg, ConnectFlags connectFlags): Emitted whenever the focus enters into the widget or one of its descendents.
addOnLeave gulong addOnLeave(void delegate(EventControllerFocus) dlg, ConnectFlags connectFlags): Emitted whenever the focus leaves the widget hierarchy that is rooted at the widget that the controller is attached to.
containsFocus bool containsFocus(): Returns %TRUE if focus is within @self or one of its children.
getEventControllerFocusStruct GtkEventControllerFocus* getEventControllerFocusStruct(bool transferOwnership): Get the main Gtk struct
getStruct void* getStruct(): the main Gtk struct as a void*
isFocus bool isFocus(): Returns %TRUE if focus is within @self, but not one of its children.
