Remarks

A CMFCToolbarButton object is a control that resides on a toolbar. Its behavior resembles that of an ordinary button. You can assign an image and a text label to this object. A toolbar button can also have a command ID. When the user clicks the toolbar button, the framework executes the command that this ID specifies.

Typically, toolbar buttons can be customized: the user can drag buttons from one toolbar to another, and copy, paste, delete, and edit text labels and images. To prevent the user from customizing the toolbar, you can lock the toolbar in one of two ways. Either set the bLocked flag to TRUE when you call CMFCToolBar::LoadToolBar, or add the command ID of an individual button to the global list of protected commands by using the CMFCToolBarButton::SetProtectedCommands method.

CMFCToolBarButton objects display images from the global collections of toolbar images in the application. These collections are maintained by the parent toolbar, CMFCToolBar Class. For more information, see CMFCToolBarImages Class.

When the user clicks a toolbar button, its parent toolbar processes the mouse message and communicates the appropriate actions to the button. If the button has a valid command ID, the parent toolbar sends the WM_COMMAND message to the parent frame.

The CMFCToolBarButton class is the base class for other toolbar button classes, such as CMFCToolBarMenuButton Class, CMFCToolBarEditBoxButton Class, and CMFCToolBarComboBoxButton Class.

Example

The following example demonstrates how to configure a CMFCToolBarButton object by using various methods in the CMFCToolBarButton class. The example illustrates how to enable the mouse and keyboard input, set the image index of the button, set the bounding rectangle of the button, and make the button visible. This code snippet is part of the Tab Control sample.

    CMFCToolBarButton* pOffice2007 = NULL;
    int nIndex = -1;
    
    for (UINT uiCmd = ID_VIEW_APPLOOK_2007_1; uiCmd <= ID_VIEW_APPLOOK_2007_4; uiCmd++)
    {
        // CMFCToolBar  m_wndToolBarTheme
        nIndex = m_wndToolBarTheme.CommandToIndex (uiCmd);

        CMFCToolBarButton* pButton = m_wndToolBarTheme.GetButton (nIndex);
    
        if (pButton != NULL)
        {
            pOffice2007 = pButton;
            break;
        }
    }


...


    pOffice2007->EnableWindow();
    pOffice2007->SetImage(1);
    pOffice2007->SetRect( CRect(1,1,1,1));
    pOffice2007->SetVisible();
    pOffice2007->Show(true);
