Hi,

perhaps section C.11.2.1.2 in part 3 of the standard might give the right answers;-)

void CElMiniViewerView::OnMouseMove(UINT nFlags, CPoint point)
{
.....
if (m_bRightMouseDown)
// if (nFlags & MK_RBUTTON) - is another way but I need this one
{
CPoint pointShift = point - m_pointRightStart; // this is the shift value

if (pointShift.x)
// change the window center or width calling finally
/// DicomImage::setWindow
if (pointShift.y)
// change the window center or width calling finally
/// DicomImage::setWindow

m_pointRightStart = point;
}
}


I had implemented it in my Miniviewer according Dr. Marco Eichelberg's piece of advice.
