Name	Description
CMFCRibbonStatusBar::OnDrawInformation	Displays the information string that appears on the ribbon status bar when the information mode is enabled.

Remarks

Users can change the visibility of ribbon elements on a ribbon status bar by using the built-in context menu for the ribbon status bar. You can add or remove elements dynamically.

A ribbon status bar has two areas: a main area and an extended area. The extended area is displayed on the right side of the ribbon status bar and appears in a different color than the main area does.

Typically, the main area of the status bar displays status notifications, and the extended area displays view controls. The extended area remains visible as long as possible when the user resizes the ribbon status bar.

Example

The following example demonstrates how to use various methods in the CMFCRibbonStatusBar class. The example shows how to add a new ribbon element to the ribbon status bar, add a ribbon element to the extended area of the ribbon status bar, add a separator, and enable the regular mode for the ribbon status bar.

 // CMFCRibbonStatusBar  m_wndStatusBar
    m_wndStatusBar.AddElement(rsbp, strTitlePane1);
    m_wndStatusBar.AddExtendedElement(new CMFCRibbonStatusBarPane(ID_STATUSBAR_PANE2, strTitlePane2, TRUE), 
        strTitlePane2);

   m_wndStatusBar.AddSeparator();
    m_wndStatusBar.SetInformation(NULL);
