[vtkusers] Update the render window

[Zhu Yong]

I use Visual C++ created an application with a splitted window. Left window 
contains some buttons and text box. What I expect is that:
when I give some value in the text boxes and click the button, the right 
render window will be updated. But now the right window won't be update 
unless I click on it. The only message handled by the right render window is 
WM_TIMER
Here is the code from the WindowProc function:
==================================================
	// TODO: Add your specialized code here and/or call the base class
	switch(message)
	{
    //case WM_PAINT:
    case WM_LBUTTONDOWN:
    case WM_LBUTTONUP:
    case WM_MBUTTONDOWN:
    case WM_MBUTTONUP:
    case WM_RBUTTONDOWN:
    case WM_RBUTTONUP:
    case WM_MOUSEMOVE:
    case WM_CHAR:
    case WM_TIMER:
      if (this->iren->GetInitialized())
      {
        return vtkHandleMessage2(this->m_hWnd, message, wParam, lParam, 
this->iren);
      }
      break;
	}

	return CView::WindowProc(message, wParam, lParam);
==============================================

Anyone can help me to figure out the problem?

Thanks
