问题
Still using VS 2008, I have split my MDI view class in my CChildFrame to facilitate a navigation sidebar (a CListCtrl) next to my old CScrollView using a static splitter (source code). This however implied two side effects: Beside the mouse wheel no longer working (where I found a workaround for), the application window is no longer updated on SetPathName(). What do I need to do to bridge the splitter so the framework updates the application window again based on my CDocument?
回答1:
On your MainFrame class, just put a method
void CMyFrame::OnUpdateFrameTitle(BOOL bAddToTitle)
{
__super::OnUpdateFrameTitle(bAddToTitle);
}
and a breakpoint there, to see what happens. If needed, you will have to provide your own override instead of calling the __super implementation.
