GestureMultiPressProtocol

public protocol GestureMultiPressProtocol : GestureSingleProtocol

GtkGestureMultiPress is a GtkGesture implementation able to recognize multiple clicks on a nearby zone, which can be listened for through the GtkGestureMultiPress::pressed signal. Whenever time or distance between clicks exceed the GTK+ defaults, GtkGestureMultiPress::stopped is emitted, and the click counter is reset.

Callers may also restrict the area that is considered valid for a >1 touch/button press through gtk_gesture_multi_press_set_area(), so any click happening outside that area is considered to be a first click of its own.

The GestureMultiPressProtocol protocol exposes the methods and properties of an underlying GtkGestureMultiPress instance. The default implementation of these can be found in the protocol extension below. For a concrete class that implements these methods and properties, see GestureMultiPress. Alternatively, use GestureMultiPressRef as a lighweight, unowned reference if you already have an instance you just want to use.

  • onPressed(flags:handler:) Extension method

GestureMultiPress Class: GestureMultiPressProtocol extension (methods and fields)

  • getArea(rect:) Extension method

    If an area was set through gtk_gesture_multi_press_set_area(), this function will return true and fill in rect with the press area. See gtk_gesture_multi_press_set_area() for more details on what the press area represents.

    Declaration

    Swift

    @inlinable
    func getArea<RectangleT>(rect: RectangleT) -> Bool where RectangleT : RectangleProtocol
  • setArea(rect:) Extension method

    If rect is non-nil, the press area will be checked to be confined within the rectangle, otherwise the button count will be reset so the press is seen as being the first one. If rect is nil, the area will be reset to an unrestricted state.

    Note: The rectangle is only used to determine whether any non-first click falls within the expected area. This is not akin to an input shape.

    Declaration

    Swift

    @inlinable
    func setArea(rect: Gdk.RectangleRef? = nil)
  • setArea(rect:) Extension method

    If rect is non-nil, the press area will be checked to be confined within the rectangle, otherwise the button count will be reset so the press is seen as being the first one. If rect is nil, the area will be reset to an unrestricted state.

    Note: The rectangle is only used to determine whether any non-first click falls within the expected area. This is not akin to an input shape.

    Declaration

    Swift

    @inlinable
    func setArea<RectangleT>(rect: RectangleT?) where RectangleT : RectangleProtocol
