JPopupMenu taller than screen

Hi,

I'm running a java app on a win2000 box and one of the popups can have
lots of entries, this causes the popup menu to be taller than the
screen and you can only select the entries shown.

Normal windows apps appear to offer the chance to move the mouse near
the bottom of a menu and then then a 2nd menu appears with the next set
of entries.

Any idea's how I can code round this problem with the java popups. Is
there a 3rd party version of the JPopupMenu or some other mechanism I
can use ?

Thanks

Steve

To get around this I would reorganize the popup-menu to contain nested
sub-menus:
JPopupMenu popupMenu = new JPopupMenu();
JMenu subMenu1 = new JMenu("1");
subMenu1.add(...);
subMenu1.add(...);
...
popupMenu.add(subMenu1);
JMenu subMenu2 = new JMenu("2");
subMenu2.add(...);
subMenu2.add(...);
...
popupMenu.add(subMenu2);

Thanks Thomas I think your right. Now time for another entry in the
group asking for any algorithms that can be used to construct the
submenu's.
