33 * @context: a #GdkDragContext.
34 * @drag_window: a window which may be at the pointer position, but
35 * should be ignored, since it is put up by the drag source as an icon.
36 * @x_root: the x position of the pointer in root coordinates.
37 * @y_root: the y position of the pointer in root coordinates.
38 * @dest_window: location to store the destination window in.
39 * @protocol: location to store the DND protocol in.
41 * Finds the destination window and DND protocol to use at the
42 * given pointer position.
44 * This function is called by the drag source to obtain the
45 * @dest_window and @protocol parameters for gdk_drag_motion().
