```
public class JSplitButton
extends JButton
implements MouseMotionListener, MouseListener, ActionListener, Serializable
```
An implementation of a "split" button.The left side acts like a normal button, right side has a jPopupMenu attached. This class raises two events.
1. buttonClicked(e); //when the button is clicked
2. splitButtonClicked(e; //when the split part of the button is clicked)
You need to subscribe to SplitButtonActionListener to handle these events. Use as you wish, but an acknowlegement would be appreciated, ;) Known Issue: The 'button part' of the splitbutton is being drawn without the border??? and this is only happening in CDE/Motif and Metal Look and Feels. GTK+ and nimbus works perfect. No Idea why? if anybody could point out the mistake that'd be nice.My email naveedmurtuza[at]gmail.com P.S. The fireXXX methods has been directly plagarized from JDK source code, and yes even the javadocs..;) The border bug in metal Look and Feel is now fixed. Thanks to Hervé Guillaume.
