Mac PopupMenu Controls Demo
These buttons bring up PopupMenus (the Buttons and the PopupMenus are
separate controls)
This Button just demonstrates mouse tracking and does nothing -- no
popup
Here's a Console control that communicates with the other controls.
Note: the actions taken by the Popups and Menus are hooked to the first
word in the name of the menu item -- "Add," "Remove,"or "Clear." Other items don't perform an action, but are still
sent to the console.
