CMFCCaptionBar::OnDrawBackground
Visual Studio 2012
Called by the framework to fill the background of the caption bar.
virtual void OnDrawBackground( CDC* pDC, CRect rect );
The OnDrawBackground method is called when the background of the caption bar is about to be filled. The default implementation fills the background by using the CMFCCaptionBar::m_clrBarBackground color.
Override this method in a CMFCCaptionBar derived class to customize the appearance of the caption bar.
