EventMotionProtocol

public protocol EventMotionProtocol

The EventMotionProtocol protocol exposes the methods and properties of an underlying GdkEventMotion 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 EventMotion. Alternatively, use EventMotionRef as a lighweight, unowned reference if you already have an instance you just want to use.

Generated when the pointer moves.

  • ptr

    Untyped pointer to the underlying GdkEventMotion instance.

    Declaration

  • _ptr Default implementation

    Typed pointer to the underlying GdkEventMotion instance.

    Default Implementation

    Return the stored, untyped pointer as a typed pointer to the GdkEventMotion instance.

EventMotion Record: EventMotionProtocol extension (methods and fields)

  • requestMotions() Extension method

    Request more motion notifies if event is a motion notify hint event.

    This function should be used instead of gdk_window_get_pointer() to request further motion notifies, because it also works for extension events where motion notifies are provided for devices other than the core pointer. Coordinate extraction, processing and requesting more motion events from a GDK_MOTION_NOTIFY event usually works like this:

    (C Language Example):

    {
  // motion_event handler
  x = motion_event->x;
  y = motion_event->y;
  // handle (x,y) motion
  gdk_event_request_motions (motion_event); // handles is_hint events
}

    Declaration

func requestMotions()
