[vtkusers] Transparency with vtkl??

[BERT Sylvain]

Hello all,

I need your help 'cause I must make the background of my vtkwindow transparent.
I have the handle of my window and I created my vtk window with vtkWin32OpenGLRenderWindow.

Do u know how to put the WS_EX_LAYERED const in my code ? Because my 
transparency function needs it.
For instance, when u create an simple window, u do:

HWND hwnd = CreateWindowEx(WS_EX_LAYERED,"MyWndClassEx","Title", 
WS_OVERLAPPEDWINDOW,......)

But with vtk ???????

Thanks to help me.

Sylvain.
