A menu containing commands that can be used from a ToolbarControl or as a popup menu.
A ToolbarMenu supplies the implementation of a menu item that can host Command, Tool, ToolControl, MultiItem and ToolbarPalette objetcs. A ToolbarMenu can either be hosted on the ToolbarControl or can appear as a popup menu.
A ToolbarMenu can be built in two ways. Firstly, an object implementing IMenuDef can be passed to the IToolbarControl::AddItem or IToolbarControl::AddMenuItem method which creates a ToolbarMenu object and populates it from the menu definition. Secondly, the properties and methods on the IToolbarMenu interface can be used to build a menu. Any sub menus on a ToolbarMenu are implemented as another instance of a IToolbarMenu.
Use the ISupportErrorInfo method InterfaceSupportsErrorInfo to determine if the object supports extended error information. If the object supports extended error info, VC++ developers should use the OLE/COM IErrorInfo interface to access the ErrorInfo object. Visual Basic developers should use the global error object Err to retrieve this extended error information.
|ISupportErrorInfo||Indicates whether a specific interface can return Automation error objects.|
|IToolbarMenu||Provides access to members that control ToolbarControl menu items.|
|IToolbarMenu2||Provides access to members that control ToolbarControl menu items.|
ToolbarMenu items support accelerator (shortcut) and access keys, defined in the ICommand::Caption property. For example, a 'Close' command with the caption "&Close\tAlt+F4" has the 'ALT+F4' key combination as its shortcut key, and the 'C' key as its access key. Although a shortcut key will always work, an access key will only work when the ToolbarMenu is active.
