Increase THICKNESS of a Scrollbar

Hi,
 I'm writting an application which interfaces on a touch-screen.  Thus the buttons need to be big, etc, so that people can easily activate them with their fingers.  Using MFC I have a CListCtrl box which is larger than it's dlg, so naturally it has (both vertical and hor.) scrollbars.  However these are cubersome when using your fingers, so I'm trying to make them thicker.  Not just the thumb pad, but the whole bar must present a larger area.  (ie take a 2x8 bar, i need a 4x8 bar).  I'm using Visual studio, C++, MFC and the generic scrollbar (I didn't do any wrappers or anything special, just a regular CListCtrl with scroll option turned on...)  Please let me know how to get that bar thicker.  
  Thanks!

I am unsure whether you can make the bar within the CListBox bigger, but if you can it will likely envolve making your own derived class.

I don't know if it is a viable option here, but you could create static scrollbars next to the list box, make them what ever size you want, then override the HScroll and VScroll messages to scroll the list box that way.

Here is a sample that should work for vertical scrolling (code goes in OnVScroll():

if( (nSBCode==SB_LINEDOWN) | (nSBCode==SB_PAGEDOWN) )
       pScrollBar->SetScrollPos(pScrollBar->GetScrollPos() + 1);
else if( (nSBCode==SB_LINEUP) | (nSBCode==SB_PAGEUP) )
       pScrollBar->SetScrollPos(pScrollBar->GetScrollPos() - 1);
m_ctlListBox.SetTopIndex(pScrollBar->GetScrollPos());

where pScrollBar is a pointer to the scrollbar sending the VScroll message, and m_ctlListBox is the CListBox.

It is an option that should work.
