class Gtk::EventControllerMotion
Overview
Gtk::EventControllerMotion is an event controller tracking the pointer
position.
The event controller offers Gtk::EventControllerMotion::#enter
and Gtk::EventControllerMotion::#leave signals, as well as
[property@Gtk.EventControllerMotion:is-pointer] and
[property@Gtk.EventControllerMotion:contains-pointer] properties
which are updated to reflect changes in the pointer position as it
moves over the widget.
Defined in:
lib/gi-crystal/src/auto/gtk-4.0/event_controller_motion.crConstructors
-
.new : self
Creates a new event controller that will handle motion events.
- .new(*, contains_pointer : Bool? = nil, is_pointer : 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_pointer : Bool
Returns if a pointer is within @self or one of its children.
- #contains_pointer? : Bool
- #enter_signal
-
#is_pointer? : Bool
Returns if a pointer is within @self, but not one of its children.
- #leave_signal
- #motion_signal
