Method Detail

getAction

Action getAction()

Construct the Action that is called when this bean's menu item/buttcon is selected. Typically this routine is only called once when the bean is added. The Action itself is called whenever the menu/buttcon is selected. The action should have NAME, SMALL_ICON and SHORT_DESC properties set. The applications uses these to put up a buttcon and menu item. The actionPerformed() method may do various things, but it must send a NewRendererEvent to any listeners, if a new renderer (map) is chosen.
