gdkEventRequestMotions {RGtk2} | R Documentation

## gdkEventRequestMotions

### Description

Request more motion notifies if `event` is a motion notify hint event. This function should be used instead of `gdkWindowGetPointer` 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:

### Usage

    gdkEventRequestMotions(event)

### Arguments

``event`` | a valid `GdkEvent`

### Details

    # motion event handler
    {
      x <- motion_event$x
      y <- motion_event$y
      # handle (x,y) motion here
      motion_event$request_motions() # handles is_hint events
    }

Since 2.12
