Locking Rebars and Toolbars

I found a way to lock the rebars like the rebars in the Windows Explorer under Win 2000/XP (which wasn't easy to do). Simply add the following code to the MainFrm.cpp where you want to lock or unlock the rebar:

CReBarCtrl& rbc = m_wndReBar.GetReBarCtrl();
REBARBANDINFO rbbi;
rbbi.cbSize = sizeof(rbbi);
rbbi.fMask  = RBBIM_STYLE;
int nCount  = rbc.GetBandCount();
for (int i  = 0; i < nCount; i++)
{
   rbc.GetBandInfo(i, &rbbi);
   rbbi.fStyle ^= RBBS_NOGRIPPER | RBBS_GRIPPERALWAYS;
   rbc.SetBandInfo(i, &rbbi);
}

The toolbars in the rebar unlocked:

And now locked:

Thanks to the CodeGuru reviewers, I also know a way to lock toolbars (not within a rebar). The idea is this: when locking controlbars, we need to disable any mouse attempts to move'em around. The key to this is to set the m_pDockBar member to NULL.

When unlocking, make sure to set it back to what it was earlier.. which means the app needs to cache these. This dirty little trick should do the job.

Add these to mainfrm.h:

CDockBar*   m_pTBDockBar;
CDockBar*   m_pDBDockBar;
BOOL m_bLocked;

Add this to mainfrm.cpp (into the constructor):

m_bLocked = FALSE;

Add this code to toggle:

DWORD dwToolbarStyle = m_wndToolBar.GetBarStyle();
DWORD dwDlgbarStyle  = m_wndDlgBar.GetBarStyle();
if(m_bLocked)
{
   // Changes the bars' style, so they have grippers
   dwToolbarStyle |= CBRS_GRIPPER;
   dwDlgbarStyle  |= CBRS_GRIPPER;
   m_wndToolBar.SetBarStyle(dwToolbarStyle);
   m_wndDlgBar.SetBarStyle(dwDlgbarStyle);

   //when removing the fixed style, set back the dockbar
   m_wndToolBar.m_pDockBar = m_pTBDockBar;
   m_wndDlgBar.m_pDockBar  = m_pDBDockBar;
}
else
{
   // Changes the bars' style, so they have not grippers
   dwToolbarStyle &= ~CBRS_GRIPPER;
   dwDlgbarStyle  &= ~CBRS_GRIPPER;
   m_wndToolBar.SetBarStyle(dwToolbarStyle);
   m_wndDlgBar.SetBarStyle(dwDlgbarStyle);

   // If the bar is floating, it will be docked before locking it.
   DockControlBar(&m_wndToolBar);
   DockControlBar(&m_wndDlgBar);

   //remove dockbar so that it cannot be moved around
   m_pTBDockBar = m_wndToolBar.m_pDockBar;
   m_pDBDockBar = m_wndDlgBar.m_pDockBar;
   m_wndToolBar.m_pDockBar = NULL;
   m_wndDlgBar.m_pDockBar  = NULL;
}

m_wndDlgBar.Invalidate();    // dialog bars need Invalidate()
RecalcLayout();
m_bLocked = !m_bLocked;

The toolbars unlocked:

And now locked:

Summary

This code has been tested on Win NT 4.0/2000/XP Pro.

Best regards, Frank

    CToolBar on WinXP, set m_pDockBar = NULL just after the three "Docking" function calls and it works.
