Remarks

CContextMenuManager manages shortcut menus and makes sure that they have a consistent appearance.

You should not create a CContextMenuManager object manually. The framework of your application creates the CContextMenuManager object. However, you should call CWinAppEx::InitContextMenuManager when your application is initialized. After initializing the context manager, use the method CWinAppEx::GetContextMenuManager to obtain a pointer to the context manager for your application.

You can create shortcut menus at runtime by calling AddMenu. If you want to show the menu without first receiving user input, call ShowPopupMenu. TrackPopupMenu is used when you want to create a menu and wait for user input. TrackPopupMenu returns the index of the selected command or 0 if the user exited without selecting anything.

The CContextMenuManager can also save and load its state to the Windows registry.

Example

The following example demonstrates how to add a menu to a CContextMenuManager object, and how not to close the active pop-up menu when the CContextMenuManager object displays a new pop-up menu. This code snippet is part of the Custom Pages sample.

    // The GetContextMenuManager method is inherited from the CWinAppEx class.
    GetContextMenuManager()->AddMenu (_T("My menu"), IDR_CONTEXT_MENU);
    GetContextMenuManager()->SetDontCloseActiveMenu(true);
