Make window stay on top

Hello,

I’m trying to make a SDL panel to use with wxWigets to play video, right
now the sdl_furface is going along with the wxPanel keeping the same
size and the same left and top coordinates, however the sdl_surface
(using YUV overlay) stays behind the wxPanel, so i ask:

Is there a way to make a sdl_surface stay on top of others windows?
