Class DragInitiator

java.lang.Object
  org.openbp.jaspira.gui.interaction.DragInitiator

All Implemented Interfaces:

java.awt.event.KeyListener, java.awt.event.MouseListener, java.awt.event.MouseMotionListener, java.util.EventListener

public class DragInitiator
extends java.lang.Object
implements java.awt.event.MouseListener, java.awt.event.MouseMotionListener, java.awt.event.KeyListener

The drag initiator supports the Jaspira-internal drag and drop mechanism for components. It will add mouse listeners that handle the dnd operations to a given component. Use the static method makeDraggable(java.awt.Component, org.openbp.jaspira.gui.interaction.DragOrigin) to make a component a drag initiator.
