There is a simple mechanism for extending the main application menus. Each menu (File, Edit and so on) reserves a standard area for adding custom items. The method StrangeEonsAppWindow.addMenuItem(targetMenu, item) is used to add new items. This method takes two parameters, an enum value (of type StrangeEonsAppWindow.AppMenu) that specifies which menu to extend, and the menu item itself. For example:
importClass(arkham.StrangeEonsAppWindow.AppMenu);
// assume that myNewCommand is a new application command we have defined
var item = new swing.JMenuItem(myNewCommand);
// Extend the File menu; possible menu choices include
// FILE, EDIT, VIEW, EXPANSION, MARKUP, DECK, SOURCE, TOOLBOX, HELP
Eons.window.addMenuItem(AppMenu.FILE, item);
One of the possible targets for addMenuItem is the Toolbox menu. This differs from the usual route, which is to create a plug-in with the ACTIVATED type. These plug-ins represent tools available in the toolbox. Menu items added to the Toolbox menu using addMenuItem should affect the toolbox itself.
The Window menu is pointedly absent from the AppMenu list. This menu is constructed automatically from the current editors and from the registered TrackedWindows. A tracked window represents a floating information window or command palette, like the script output console. Tracked windows are always present and available, but may be shown or hidden by selecting their Window menu item. Tracked windows are registered using the StrangeEonsAppWindow.startTracking(trackedWindow) method.
