CMFCPopupMenu::CreateTearOffBar | |
CMFCPopupMenu::OnChangeHot | |

Normally, MFC creates pop-up menus automatically. If you want to create a CMFCPopupMenu
object manually, allocate one on the heap and then call CMFCPopupMenu::Create.
The following example demonstrates how to configure a pop-up menu object. The example shows how to set the logo and the sound of the pop-up menu, set the animation speed and type, draw menu shadows when the pop-up menu appears outside the main frame, set the maximum width, and set the right menu alignment of the pop-up menu. This code snippet is part of the Custom Pages sample.
