Method Detail

menuKeyTyped

public void menuKeyTyped(MenuKeyEvent e)

Handles the mnemonic key typed in the MenuItem if this menuItem is in a standalone popup menu. This invocation normally handled in BasicMenuUI.MenuKeyHandler.menuKeyPressed. Ideally, the MenuKeyHandlers for both BasicMenuItemUI and BasicMenuUI can be consolidated into BasicPopupMenuUI but that would require an semantic change. This would result in a performance win since we can shortcut a lot of the needless processing from MenuSelectionManager.processKeyEvent(). See 4670831.
