SEMPER Launchable Applications Facility

This facility provides a single pull-down menu on Tinguin. Other blocks can register individual menu items by using the services provided by this facility. It supports nested menu. To add an item, you have to first get a handle to the top-level menu using the getTopMenu method in class ApplicationsMenu . Once you have a handle to this object, you can add a simple menu item using registerApp() or a submenu using addSubMenu() .

It is intended that other blocks will use this method during their initialisation (invoked from Library initialisation service . At the end of library initialisation, the menu will be closed. Attempts to register menu items after this will fail.

If a block wants to register an application to be launchable from this menu, the application must be implemented in the form of a class that can be publicly instantiated and implements the MenuLaunchable interface.

Here an example usage:

    ApplicationsMenu.register(new AppMenuTest("topitem 1"), "TopItem 1");

    // Get the top level menu and make a submenu
    ApplicationsMenu top = ApplicationsMenu.getTopMenu();
    ApplicationsMenu subMenu1 = top.addSubMenu("SubMenu 1");
    subMenu1.registerApp (new AppMenuTest("subItem 1.1"), "SubItem 1.1");
    subMenu1.registerApp (new AppMenuTest("subItem 1.2"), "SubItem 1.2");

    // Make another submenu
    ApplicationsMenu subMenu2 = subMenu1.addSubMenu("SubMenu 1.1");
    subMenu2.registerApp (new AppMenuTest("subItem 2.1"), "SubItem 2.1");
    subMenu2.registerApp (new AppMenuTest("subItem 2.2"), "SubItem 2.2");
