class Gtk::GestureRotate
Overview
Gtk::GestureRotate
is a Gtk::Gesture
for 2-finger rotations.
Whenever the angle between both handled sequences changes, the [signal@Gtk.GestureRotate::angle-changed] signal is emitted.
Defined in:
lib/gi-crystal/src/auto/gtk-4.0/gesture_rotate.crConstructors
-
.new : self
Returns a newly created
Gtk::Gesture
that recognizes 2-touch rotation gestures. - .new(*, n_points : UInt32? = 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
- #angle_changed_signal
-
#angle_delta : Float64
Gets the angle delta in radians.
