    This article extends the article CSizingControlBar - a resizable control bar by Cristi Posea.
    Webmaster's note: the CSizingControlBar class used in this code is an earlier version; follow the link above for the latest one.

    Features

    The Control bar like in DevStudio, which has TabControls with different Views (like TreeViews) and it can be docked and resized.

    Instructions

    Add the following class to your project:

    • CSizingControlBar
    • CSizingTabCtrlBar

    Add a member variable to CMainFrame (in mainfrm.h):

    CSizingTabCtrlBar m_wndSTCBar;
    

    Create the bar in CMainFrame::OnCreate(). Then set bar styles, enable it to dock... like any control bar. Be sure to add IDW_PROP_BAR to the "resource.h" and to add the bitmap IDB_TABIMAGES to your resources.

    // SizingControlBar
    m_wndSTCBar.Create(this, CSize(200, 1), IDW_PROP_BAR);
    m_wndSTCBar.SetBarStyle(m_wndToolBar.GetBarStyle() |
    	CBRS_TOOLTIPS | CBRS_FLYBY | CBRS_SIZE_DYNAMIC);
    m_wndSTCBar.EnableDocking(CBRS_ALIGN_ANY);
    DockControlBar(&m_wndSTCBar, AFX_IDW_DOCKBAR_LEFT);
    
    m_wndSTCBar.AddView("Database", RUNTIME_CLASS(CClassView));
    m_wndSTCBar.AddView("Files", RUNTIME_CLASS(CFileView));
    

    As you can see, the different views are added by calling

    m_wndSTCBar.AddView("Files", RUNTIME_CLASS(CFileView));
    

    Thats the only thing you have to do, to add a view!

    Override CMainFrame::RecalcLayout().
    Note: use the base framewnd class member function, ie if you have an SDI application replace CMDIFrameWnd with CFrameWnd below.

    void CMainFrame::RecalcLayout(BOOL bNotify) 
    {
    	CMDIFrameWnd::RecalcLayout(bNotify);
    	CMDIFrameWnd::RecalcLayout(bNotify);
    }
    

    To call a view from the Mainframe:

    CFileView* pView = (CFileView*)
    	m_wndSTCBar.GetView(RUNTIME_CLASS(CFileView));
    pView->UpdateView();	// or do anything else
    m_wndSTCBar.SetActiveView(RUNTIME_CLASS(CFileView));

    I like this dock window but it seems to give me some trouble. I need two tabs with different treeview. I've learned a lot from here but need some corrections. Thanks to Mark Conway from CodeGuru (Dock demo/docktest).But I did not use those dlls, I have combine from there and here, based on CSizingControlBar. I did not create any special class to support the treeview like the sample "MY Bar", but I lost something, here:
     
    This is cpp: I define the ID tab here.
    #define IDC_TREEBAR_TAB 1001
     
    ///////////////////////////////////////////////////////////////////////////// I use workspace instead My Bar.
    // CWorkspaceBar

    It looks quite simple but needs fix.
