GestureSingleRef

public struct GestureSingleRef : GestureSingleProtocol, GWeakCapturing

GtkGestureSingle is a subclass of GtkGesture, optimized (although not restricted) for dealing with mouse and single-touch gestures. Under interaction, these gestures stick to the first interacting sequence, which is accessible through gtk_gesture_single_get_current_sequence() while the gesture is being interacted with.

By default gestures react to both GDK_BUTTON_PRIMARY and touch events, gtk_gesture_single_set_touch_only() can be used to change the touch behavior. Callers may also specify a different mouse button number to interact with through gtk_gesture_single_set_button(), or react to any mouse button by setting 0. While the gesture is active, the button being currently pressed can be known through gtk_gesture_single_get_current_button().

The GestureSingleRef type acts as a lightweight Swift reference to an underlying GtkGestureSingle instance. It exposes methods that can operate on this data type through GestureSingleProtocol conformance. Use GestureSingleRef only as an unowned reference to an existing GtkGestureSingle instance.

  • ptr 
    Untyped pointer to the underlying `GtkGestureSingle` instance.

    For type-safe access, use the generated, typed pointer gesture_single_ptr property instead.
