How to create a splitted button with a popup menu?

Question

Hi,
i am trying to build a button which can be clicked and an action is called (a normal button) and an addion to that basic function: there is on the right side of the button a seperated area with an arrow. If this arrow is clicked a popup menu becomes visible and you can choose a special action. This type of buttons (i don't know the name) can be seen by example in Eclipse or the Windows Media Player 11 or in Windows Vista).
Here is an example image about what i mean: http://s2.imgimg.de/uploads/button56b4941cpng.png
Can you tell me how to create a button with this possabilities?
Please help me,

hii,
if you are want completed to define the Popup, then you have to define accesible areas,
1/ create Popup (example from void)
public void createPopupMenu() {
JPopupMenu popup = new JPopupMenu();
popup.addSeparator();
ShowsManFxMenuItem = new JMenuItem("Show Details");
ShowsManFxMenuItem.addActionListener((new ActionListener() {
public void actionPerformed(ActionEvent e) {
//..some actions
validate();
repaint();
popup.add(ShowsManFxMenuItem);
MouseListener popupListener = new PopupListener(popup);
//here is your listener directly to prepared object "yourButton"
yourButton.addMouseListener(popupListener);
2/ create POpupListener (example is class)
class PopupListener extends MouseAdapter {
JPopupMenu popup;
PopupListener(JPopupMenu popupMenu) {
popup = popupMenu;
@Override
public void mousePressed(MouseEvent e) {
maybeShowPopup(e);
@Override
public void mouseReleased(MouseEvent e) {
maybeShowPopup(e);
//only in this block you can restrict anything with popup items (test anything and then to display all, only one, parts of them)
private void maybeShowPopup(MouseEvent e) {
if (e.isPopupTrigger()) {
popup.show(e.getComponent(), e.getX(), e.getY());
//these parts you can ingnore, but can covered extended events from popup
public void actionPerformed(ActionEvent e) {
JMenuItem source = (JMenuItem) (e.getSource());
public void itemStateChanged(ItemEvent e) {
JMenuItem source = (JMenuItem) (e.getSource());
protected String getClassName(Object o) {// Returns just the class name -- no package info.
String classString = o.getClass().getName();
int dotIndex = classString.lastIndexOf(".");
return classString.substring(dotIndex + 1);
