<DIV><FONT size=2>There are four view port in the render window.I want to add
user-defined message to one of them,for exampe add LeftBottonDown Message to the
axial image.I want to achieve the aim that when I press the left button of the
mouse ,in the according view port will display the coordinates.I use the
vtkMFCRenderView to be the base class of my view class.And I add the
OnLButtonDown() message as follows.</FONT></DIV>
<DIV><FONT size=2>void CMyView::OnLButtonDown(UINT nFlags, CPoint point)
<BR>{<BR> // TODO: Add your message handler code here and/or call
default<BR> <BR> //CView::OnLButtonDown(nFlags, point);</FONT></DIV>
<DIV> </DIV>
<DIV><FONT
size=2> vtkMFCRenderView::OnLButtonDown(nFlags,point);<BR>}</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>But the result is not changed.What I get is still the
vtkRenderWindowInteractor control style. I don't know what is the reason?Why it
doesn't respond my defined message.</FONT></DIV></BODY></HTML>
