[vtkusers] F10 and ALT keys

[jean-michel.rouet at philips.com]

Hello all,

I search google but didn't find any significant answers.

Here is my problem:
Under win32, the ALT and F10 keys are not handled the same way as the 
others.
Thus the KeyPress event is not generated, and there is no way for a VTK 
application to
react on such keys.
Apparently, win32 generates a WM_SYSKEYUP and WM_SYSKEYDOWN message 
instead of the WM_KEYUP and WM_KEYDOWN.
Can a change to vtkWin32RenderWindowInteractor.cxx be made ?

like: 

+    case WM_SYSKEYDOWN:
    case WM_KEYDOWN:
      me->OnKeyDown(hWnd,wParam,LOWORD(lParam),HIWORD(lParam));
      break;

+    case WM_SYSKEYUP:
    case WM_KEYUP:
      me->OnKeyUp(hWnd,wParam,LOWORD(lParam),HIWORD(lParam));
      break;

in the 
LRESULT CALLBACK vtkHandleMessage2(HWND hWnd,UINT uMsg, WPARAM wParam, 
                                   LPARAM lParam, 
                                   vtkWin32RenderWindowInteractor *me) 
function.


Does it make sense ?

Regards,
JM
