/**
 * Constructs new DockEvent event..
 * 
 * @param source the source of the event. Can be null.
 * @param target the target of the event. Can be null.
 * @param eventType The type of the event.
 * @param x The x with respect to the source. Should be in scene coordinates if source == null or
 *        source is not a Node.
 * @param y The y with respect to the source. Should be in scene coordinates if source == null or
 *        source is not a Node.
 * @param screenX The x coordinate relative to screen.
 * @param screenY The y coordinate relative to screen.
 * @param pickResult pick result. Can be null, in this case a 2D pick result without any further
 *        values is constructed based on the scene coordinates
 * @param contents The contents being dragged during this event.
