Popup Menu Demo
This class lets any of your AWT components have a popup menu.
But some work out better than others.
Popups work fine based on a Panel or a Label or a Canvas.
They have problems if based on a Button or TextArea.
The actual Menu choices may be ordinary MenuItems,
or CheckboxMenuItems.
They were known to be broken for a long time,
but 1.1.5 finally fixed them.
A Popup menu can have a pullright menu.
This PopupDemo.java applet
demonstrates what works and what does not.
The problems if based on a Button appear due to a bug in the peer,
the problems with TextArea are conflicts with the built-in popup.
It does require the 1.1 event model.
