[vtkusers] Update the render window

[Zhizhong Zhang]

you need to send out a message to the right window and tell it to update the window. Your assertion that only WM_TIMER is handled is incorrect. In fact, all the messages in the switch block are handled, the same way(that's why the right window is updated when you click in it). You can look up SendMessage to  figure out how to send a message.

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
