The menus are specified by a list of lists (actually, an iterable of iterables, but the term ‘list’ will be used here to mean any iterable). Framework provides 7 menus: Project, Spectrum, Molecules, View, Macro, Plugins, Help. If you want to create your own menu in a subclass of Framework, you need to create a list in the style described below, then call self.addApplicationMenuSpec and pass in your menu specification list. Menu specification lists are composed of two items, the first being a string which is the menu’s title, the second is a list of sub-menu items. Each item can be zero, two or three items long. A zero-length list indicates a separator. If the list is length two and the second item is a list, then it specifies a sub-menu in a recursive manner. If the list is length two and the second item is callable, it specifies a menu action with the first item specifying the label and the second the callable that is triggered when the menu item is selected. If the list is length three, it is treated as a menu item specification, with the third item a list of keyword, value pairs. The examples below may make this more clear… Create a menu called ‘Test’ with two items and a separator: | - Test | | - Item One | | - ------ | | - Item Two Where clicking on ‘Item One’ calls method self.itemOneMethod and clicking on ‘Item Two’ calls self.itemTwoMethod | def setupMenus(self): | menuSpec = (‘Test’, [(‘Item One’, self.itemOneMethod), | (), | (‘Item Two’, self.itemTwoMethod), | ] | self.addApplicationMenuSpec(menuSpec) More complicated menus are possible. For example, to create the following menu | - Test | | - Item A ia | | - ------ | | - Submenu B | | - Item B1 | | - Item B2 | | - Item C id where Item A can be activated using the two-key shortcut ‘ia’, Submenu B contains two static menu items, B1 and B2 Submenu item B2 is checkable, but not checked by default Item C is disabled by default and has a shortcut of ‘ic’ | def setupMenus(self): | subMenuSpecB = [(‘Item B1’, self.itemB1), | (‘Item B2’, self.itemB2, [(‘checkable’, True), | (‘checked’, False)]) | ] | | menuSpec = (‘Test’, [(‘Item A’, self.itemA, [(‘shortcut’, ‘ia’)]), | (), | (‘Submenu B’, subMenuB), | (‘Item C’, self.itemA, [(‘shortcut’, ‘ic’), | (‘enabled’, False)]), | ] | self.addApplicationMenuSpec(menuSpec) If we’re using the PyQt GUI, we can get the Qt action representing Item B2 somewhere in our code (for example, to change the checked status,) via: | action = application.ui.mainWindow.getMenuAction(‘Test->Submenu B->Item B2’) | action.setChecked(True) To see how to add items dynamically, see clearRecentProjects in this class and _fillRecentProjectsMenu in GuiMainWindow """ self._menuSpec = ms = [] ms.append(('File', [ ("New", self._newProjectCallback, [('shortcut', '⌃n')]), # Unicode U+2303, NOT the carrot on your keyboard.
