Discussion
This call sets up the popup button cell to display a menu, which occurs in performClick(withFrame:in:). This method sets the cell’s control view and then highlights and redraws the cell. It does not show the menu.
This method also posts an willPopUpNotification. (The NSPopUpButton object sends a corresponding willPopUpNotification.)
You normally do not call this method explicitly. It is called by the Application Kit automatically when the menu for the pop-up button is to be displayed.
