Remarks

A CMFCToolBarMenuButton can appear as a menu, a menu item that has a sub-menu, a button that either executes a command or displays a menu, or a button that displays only a menu. You determine the behavior and appearance of the menu button by specifying parameters such as the image, text, menu handle, and command ID that is associated with the button in the constructor CMFCToolbarMenuButton::CMFCToolbarMenuButton.

A custom class derived from the CMFCToolbarMenuButton class must use the DECLARE_SERIAL macro. The DECLARE_DYNCREATE macro generates an error when the application closes.

Example

The following example demonstrates how to configure a CMFCToolBarMenuButton object. The code illustrates how to specify that the drop-down menu is in palette mode, and specify the ID for the tear-off bar that is created when the user drags the menu button off of a menu bar. This code snippet is part of the WordPad Sample: MFC WordPad Application.

    pBorderType->SetMenuPaletteMode (TRUE, 2 /* Rows number */);
    pBorderType->SetTearOff (ID_BORDER_TEAROFF);
