If you need to enable the display of a Panel (an AWT component), you can configure it at the individual
JPopupMenu level or for your entire applet or application.
At the individual pop-up level, just set the lightWeightPopupEnabled property to false.
The setInheritsPopupMenu() method accepts a boolean argument.
When true, and no component pop-up menu has been directly set for the component, the parent container will be explored for a pop-up.
At the system level, this is done as follows:
// From now on, all JPopupMenus will be heavyweight
JPopupMenu.setDefaultLightWeightPopupEnabled(false);
