Description

Takes the specified menu and creates a new item that is added to the ToolbarControl and returns the index of the menu item added. This is really a shortcut to AddItem.

Specifiy the menu as either a IUID , ProgID, IMenuDef or IToolbarMenu.

If AddIMenuItem is passed an IMenuDef, the menu definition is is used to build a new ToolbarMenu, and the IToolbarMenu::CommandPool is set to the IToolbarControlDefault::CommandPool. If AddMenuItem is passed an IToolbarMenu a new ToolbarItem is created and the IToolbarItem::Menu is set to the IToolbarMenu.

index determines the position on the ToolbarControl that the Item will be added to. By default this is -1 and represents the end of the ToolbarControl.

beginGroup determines whether a separator will appear before the Item. By default beginGroup is False.

GroupSpacing determines the width in pixels of the separator.

Errors Returned

1023 800a03ff: The specified index is out of range
1047 800a0417: Errors occurred adding the specified menu to the toolbar
1064 800a0428: A command or a toolbar cannot be added as a menu item.

Remarks

AddItem checks to see if each command in the menu already exists in the CommandPool used by the ToolbarControl. If the command does not already exist, it is created and added to the CommandPool with a ICommandPool::UsageCount of 1. If the command already exists in the CommandPool its ICommandPool::UsageCount is incremented by 1. The ICommand::OnCreate method will be called the first time a command is added to the CommandPool.

Where possible always supply menus as either Uid objects or ProgID's. Only supply menu as IMenuDef objects when a IUid or ProgID does not exist, and the class is compiled as part of the same project using the ToolbarControl.
