Adding CEikScrollBarFrame to a container

Hi all,

I have a problem to using CEikScrollBarFrame.  I would like to add scrolling to my container control.  I had carbide generate a GUI application and updated ConstructL to add scroll bars to it.  CScrollableViewContainerView has a pointer to CScrollableViewContainer. There is nothing special there.  It is just the standard automatically generated code.  The problem is that no scroll bar shows up! Any idea?


class CScrollableViewContainerView : public CAknView

class CScrollableViewContainer : public CCoeControl, public MEikScrollBarObserver

void CScrollableViewContainer::ConstructL(
      const TRect& aRect,
      const CCoeControl* aParent,
      MEikCommandObserver* aCommandObserver )
   {
   if ( aParent == NULL )
   Â    {
      CreateWindowL();
   Â    }
   else
   Â    {
   Â    SetContainerWindowL( *aParent );
   Â    }
   iFocusControl = NULL;
   iCommandObserver = aCommandObserver;
   InitializeControlsL();
   
    m_scrollBarFrame = new (ELeave) CEikScrollBarFrame( this, NULL, ETrue );
    m_scrollBarFrame->SetScrollBarVisibilityL( CEikScrollBarFrame::EOn, CEikScrollBarFrame::EOn/*EOn*/ );
 
   TEikScrollBarModel&    modelV = GetScrollBarModelV();
   TEikScrollBarModel&    modelH = GetScrollBarModelH();

   modelV.iThumbSpan       = aRect.Height()/2+1; /** Entire range of integers for this model. */
   modelV.iThumbPosition    = 0;   /** Position of the low edge of the thumb within 0...@c iScrollSpan. */
   modelV.iScrollSpan       = aRect.Height()*10;    /** Range spanned by the thumb. */

   modelH.iThumbSpan       = aRect.Width()/2+1;  /** Entire range of integers for this model. */
   modelH.iThumbPosition    = 0;   /** Position of the low edge of the thumb within 0...@c iScrollSpan. */
   modelH.iScrollSpan       = aRect.Width()*10;   /** Range spanned by the thumb. */
   
   m_scrollBarFrame->Tile(&modelH, &modelV);
   m_scrollBarFrame->MoveHorizThumbTo(modelH.iThumbPosition);
   m_scrollBarFrame->MoveVertThumbTo(modelV.iThumbPosition);
   m_scrollBarFrame->DrawScrollBarsNow();
   
   SetRect( aRect );   
   ActivateL();
   // [[[ begin generated region: do not modify [Post-ActivateL initializations]
   // ]]] end generated region [Post-ActivateL initializations]
   
   }
