[vtkusers] vtkRenderWindowInteractor does not process key events

[Daniel Lüken]

Thanks! That worked!

Here are some codesnippets for that solution:

LRESULT CALLBACK wndProc(HWND hWnd, UINT message, UINT wParam, LONG lParam)
{
...
switch(message)
{
...
case WM_SETFOCUS:
SetFocus(theVTKApp->getWnd());
return 0;
break;
...
}
}

HWND myVTKApp::getWnd()
{
return (renWin != NULL) ? (HWND)renWin->GetGenericWindowId() : 0;
}

For the Win32/Windows case, make sure you intercept WM_SETFOCUS in
your parent window and call SetFocus on the VTK child HWND. Otherwise,
the VTK child window will never get keyboard focus.....

I'm not sure what the equivalent Motif thing to do is for you X-windows 
users...
