The following code sometimes draws the scroll bar when the content does not exceed the window. Then when moving the mouse pointer over the scroll bar the area under the mouse is drawn correctly, leaving a partially drawn scroll bar!


bool CNavCtrl::OnGbwAnalyzeCellMouseClickEvent(UINT nChar,UINT nRepCnt, UINT nFlags, CPoint point)
{
    bool bRet = CExtTreeGridWnd::OnGbwAnalyzeCellMouseClickEvent(nChar, nRepCnt, nFlags, point);

    CExtGridHitTestInfo htInfo(point);
    HitTest(htInfo, false, true);
    if(htInfo.m_dwAreaFlags & __EGBWA_INNER_CELLS)
    {
        if(nChar == VK_LBUTTON)
        {
            if(htInfo.m_nRowNo)
            {
                HTREEITEM hti = ItemGetByVisibleRowIndex(htInfo.m_nRowNo);
                if(ItemGetParent(hti) == ItemGetRoot())
                {
                    ItemExpand(hti);
                    return true;
                }
            }
        }
    }

return bRet;
}

Still waiting ...

Any news?

Just got back from Paris ... test project now sent.

Still didn’t receive any e-mail from you.

I’ve tried that and it doesn’t fix it ... I’ll send a sample project.

The code snippet in your message didn’t help us to reproduce the problem. You can invoke OnSwUpdateScrollBars(); before return true; to fix this problem.
