Hide Scrollbars from a CListCtrl

Environment: VC++ 6.0, WinXP
Short description: Removes the scrollbars from a CListCtrl without losing the ability to scroll.


When you create a CListCtrl with the "NO SCROLL" option, it completely stop scrolling. If the data is out of the screen, you do not see anything. So, you always had to use the scrollbars, until now!

I've used this for many kiosk software solutions, and it gives you complete control of the CListCtrl.

Using the Code

The CListCtrlHiddenSB is derived from CListCtrl. It has one function to hide the scrollbars: HideScrollBars(int Type, int Which).

  • The Type variable has two const: LCSB_CLIENTDATA and LCSB_NCOVERRIDE.
  • The Which variable tells which scrollbar will be hidden; here we use the default: SB_BOTH, SB_HORZ, and SB_VERT.

The Clientdata type of hiding scrollbars must be called BEFORE any data is entered because this will change the clientrect of the control to be smaller.

In the demo project, I override the normal constructor, like this:

class CCListCtrlExampleDlg : public CDialog
// Construction
  CCListCtrlExampleDlg(CWnd* pParent = NULL);    // standard
                                                 // constructor

  //These are the defs for each type of how we hide the scrollbars
// Dialog Data
  CListCtrlHiddenSB m_list4;
  CListCtrlHiddenSB m_list3;
  CListCtrlHiddenSB m_list2;
  CListCtrlHiddenSB m_list1;

  // ClassWizard generated virtual function overrides
  virtual void DoDataExchange(CDataExchange* pDX);    // DDX/DDV
                                                      // support

Just before the listctrls are filled with data, we hide the scrollbars:

  m_list1.HideScrollBars(LCSB_CLIENTDATA, SB_VERT);




Known Issues

If you have a listctrl that will just get a horizontal scrollbar and you choose to hide both of the scrollbars, the function will also remove the vertical scrollbar. But, because it is not there, some of the gfx will be cut off.

In other words, the clientarena should only be used when you KNOW how many scrollbars will be shown.

Personally, I prefer using the NcCalcSize. It removes the scrollbars pretty smoothly. It doesn't care whether the listctrl shows all scrollbars or not.

  • Applying "NcCalcSize" trick under CE

    Posted by Codeplug on 05/12/2004 01:24pm

    I'm running CE 2.12, which doesn't support the WM_NCCALCSIZE.
    Through trial and error, I discovered that the same trick works 
    when intercepting WM_SIZE instead of WM_NCCALCSIZE. 
    The only caveat is that you must call the following for the 
    style removal to take effect:
    ::SetWindowPos(hwnd, NULL, 0, 0, 0, 0,
                   SWP_NOSIZE | SWP_NOMOVE | SWP_NOZORDER | 
    Or in terms of MFC, you would call:
