Remarks

The CMFCMenuBar class is a menu bar that implements docking functionality. It resembles a toolbar, although it cannot be closed - it is always displayed.

CMFCMenuBar supports the option of displaying recently used menu item objects. If this option is enabled, the CMFCMenuBar displays only a subset of the available commands on first viewing. Thereafter, recently used commands are displayed together with the original subset of commands. In addition, the user can always expand the menu to view all available commands. Thus, each available command is configured to display constantly, or to display only if it has been recently selected.

To use a CMFCMenuBar object, embed it in the main window frame object. When processing the WM_CREATE message, call CMFCMenuBar::Create or CMFCMenuBar::CreateEx. Regardless of which create function you use, pass in a pointer to the main frame window. Then enable docking by calling CFrameWndEx::EnableDocking. Dock this menu by calling CFrameWndEx::DockPane.

Example

The following example demonstrates how to use various methods in the CMFCMenuBar class. The example shows how to set the style of the pane, enable the customize button, enable a Help box, enable shadows for pop-up menus, and update the menu bar. This code snippet is part of the IE Demo sample.

 CMFCMenuBar m_wndMenuBar;


...


    m_wndMenuBar.SetPaneStyle(m_wndMenuBar.GetPaneStyle() | CBRS_SIZE_DYNAMIC);
    m_wndMenuBar.EnableCustomizeButton (TRUE, -1, _T(""));
    // first parameter is the command ID for the button of the Help combo box 
    // third parameter is the width of the button for the combo box in pixels.
    m_wndMenuBar.EnableHelpCombobox(1,_T("enter text here"),30);
    m_wndMenuBar.EnableMenuShadows();
    m_wndMenuBar.SetMaximizeMode(true);
