Remarks
A CMFCDropDownToolBarButton differs from an ordinary button in that it has a small arrow in the lower-right corner of the button. After the user selects a button from the drop-down toolbar, the framework displays its icon on the top-level toolbar button (the button with the small arrow in the lower-right corner).
For information about how to implement a drop-down toolbar, see CMFCDropDownToolBar Class.
The CMFCDropDownToolBarButton object can be exported to a CMFCToolBarMenuButton Class object and displayed as a menu button with a pop-up menu.
