protected Builder()

Default constructor for a Builder object.

Method Details

build

public EventControllerFocus build()

Finish building the EventControllerFocus object. This will call GObject.withProperties(org.gnome.glib.Type, java.lang.String[], org.gnome.gobject.Value[]) to create a new GObject instance, which is then cast to EventControllerFocus.

Overrides:

build in class EventController.Builder<B extends EventControllerFocus.Builder<B>>

Returns:

a new instance of EventControllerFocus with the properties that were set in the Builder object.

onEnter

public B onEnter(EventControllerFocus.EnterCallback handler)

Emitted whenever the focus enters into the widget or one of its descendents.

Note that this means you may not get an ::enter signal even though the widget becomes the focus location, in certain cases (such as when the focus moves from a descendent of the widget to the widget itself). If you are interested in these cases, you can monitor the Gtk.EventControllerFocus:is-focus property for changes.

Parameters:

handler - the signal handler

Returns:

the Builder instance is returned, to allow method chaining

See Also:

• EventControllerFocus.EnterCallback.run()

onLeave

public B onLeave(EventControllerFocus.LeaveCallback handler)

Emitted whenever the focus leaves the widget hierarchy that is rooted at the widget that the controller is attached to.

Note that this means you may not get a ::leave signal even though the focus moves away from the widget, in certain cases (such as when the focus moves from the widget to a descendent). If you are interested in these cases, you can monitor the Gtk.EventControllerFocus:is-focus property for changes.

Parameters:

handler - the signal handler

Returns:

the Builder instance is returned, to allow method chaining

• EventControllerFocus.LeaveCallback.run()
