Docking Toolbars Side-By-Side

There are many articles about docking toolbars. However, I felt that this was important enough to mention here. The same information can be found at Microsoft's MSDN site. Here it is in a nutshell...

Add the following method to your CMainFrame class:

void CMainFrame::DockControlBarLeftOf(
                        CToolBar* Bar, CToolBar* LeftOf)
{
    CRect rect;
    DWORD dw;
    UINT n;

    // get MFC to adjust the dimensions of all docked ToolBars
    // so that GetWindowRect will be accurate
    RecalcLayout(TRUE);

    LeftOf->GetWindowRect(&rect);
    rect.OffsetRect(1,0);
    dw=LeftOf->GetBarStyle();
    n = 0;
    n = (dw&CBRS_ALIGN_TOP) ? AFX_IDW_DOCKBAR_TOP : n;
    n = (dw&CBRS_ALIGN_BOTTOM && n==0) ?
                                AFX_IDW_DOCKBAR_BOTTOM : n;
    n = (dw&CBRS_ALIGN_LEFT && n==0) ?
                                AFX_IDW_DOCKBAR_LEFT : n;
    n = (dw&CBRS_ALIGN_RIGHT && n==0) ?
                                AFX_IDW_DOCKBAR_RIGHT : n;

    // When we take the default parameters on rect, DockControlBar
    // will dock each Toolbar on a seperate line. By calculating a
    // rectangle, we are simulating a Toolbar being dragged to that
    // location and docked.
    DockControlBar(Bar,n,&rect);
}

Now, in your CMainFrame::OnCreate, instead of using DockControlBar, use DockControlBarLeftOf:

m_wndToolBar1.EnableDocking(CBRS_ALIGN_ANY);
m_wndToolBar2.EnableDocking(CBRS_ALIGN_ANY);
EnableDocking(CBRS_ALIGN_ANY);
DockControlBar(&m_wndToolBar1);
DockControlBarLeftOf(&m_wndToolBar2,&m_wndToolBar1);

This will dock m_wndToolBar2 left of m_wndToolBar1.
