DragComponentEvent

public DragComponentEvent()

This event is reusable because we do not want to overload the GC when the mouse is moved around. When reusing the same event, use this constructor once and call set to adjust the values.

Method Detail

set

public void set(java.awt.Component src,
                java.awt.Point ptMouse,
                int nID,
