Overview
Gtk::EventControllerFocus is an event controller to keep track of
keyboard focus.
The event controller offers Gtk::EventControllerFocus::#enter
and 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.
Defined in:
lib/gi-crystal/src/auto/gtk-4.0/event_controller_focus.crConstructors
-
.new : self
Creates a new event controller that will handle focus events.
- .new(*, contains_focus : Bool? = nil, is_focus : Bool? = nil, name : String? = nil, propagation_limit : Gtk::PropagationLimit? = nil, propagation_phase : Gtk::PropagationPhase? = nil, widget : Gtk::Widget? = nil)
Class Method Summary
-
.g_type : UInt64
Returns the type id (GType) registered in GLib type system.
Instance Method Summary
-
#contains_focus : Bool
Returns
trueif focus is within @self or one of its children. - #contains_focus? : Bool
- #enter_signal
-
#is_focus? : Bool
Returns
trueif focus is within @self, but not one of its children. - #leave_signal
