Remarks

In order to use tear-off menus in your application, you must have a CMenuTearOffManager object. In most cases, you won't create or initialize a CMenuTearOffManager object directly. This is handled for you when you call the CWinAppEx::EnableTearOffMenus function.

Example

The following example demonstrates how to construct and initialize a CMenuTearOffManager object by calling the CWinAppEX::EnableTearOffMenus method. This code snippet is part of the Word Pad sample.

// The EnableTearOffMenus method is inherited from the CWinAppEx class.
EnableTearOffMenus(NULL, ID_FREE_TEAROFF1, ID_FREE_TEAROFF2);
