Printing CTreeView

Hi,

I am using a CTreeView in a SDI app as view. CMyView, derived from CTreeView
has a OnDraw Method, but it is not called when I resize the application
Window. The Tree is painted as soon as I add the elements with TVinsertItem
- no more calls to OnDraw?

Now I want to print that TreeView - but nothing turns up on the preview page
- nothing is on the printer, exept for a test text written with pDC->TextOut
in OnDraw.

Is there a chance to I make CTreeView use the MFC printing features or do I
have to do it all by hand?

thanks for your answer

Edgar

In your OnDraw function, do as follows:

if(pDC->IsPrinting())
{
        GetTreeCtrl()->SendMessage(WM_PAINT,(HDC)pDC->m_hDC,0);
}
// your previous paint code ...
