The CheckboxMenuItems utilized in the Speed and Background submenus are meant to act as radio buttons, so that the selection of one will disable the previous selection. speedItems[] stores all the check boxes for the Speed menu, and colourItems[] all the background color check boxes. These arrays are manipulated by the itemStateChanged() method to simulate the behavior of radio buttons. The Edit Rules, About, and Contact Author menu items require the Desktop API, so the GUI code checks for its presence before attaching the action listener. It also uses Desktop.isSupported() to determine whether the API supports the action required by the menu item: Edit Rules needs text editing; About utilizes text viewing; and Contact Author requires an e-mail client. If the checking fails, the menu item is disabled. The Exit menu is assigned a key combination shortcut (Ctrl-Shift-x) as a MenuShortcut object. Unfortunately, it doesn t work in the version of Java SE I m using, v.1.6.0. (By the way, Ctrl is replaced by the Command key on the Mac.) The five menu items ((De)Iconify, Edit Rules, About, Contact Author, and Exit use an action listener, while the Speed and Background check boxes use an item listener. how to read data from barcode scanner in java Barcode scanner doesn't detect by mobile browser · Issue #18 ...
