Description gregory.hainaut 2011-05-02 11:20:23 UTC 
Hello,

I try to use the SDL_CreateWindowFrom function on X11 system.

As wiki said: http://wiki.libsdl.org/moin.cgi/SDL_CreateWindowFrom you need to send a void pointer to the window.

/* my code */
Window glWindow = ...;
m_window = SDL_CreateWindowFrom((void*)&glWindow);

But SDL does not take the content of the pointer but the pointer itself.
/* SDL code */
X11_CreateWindowFrom(_THIS, SDL_Window * window, const void *data)
 {
     Window w = (Window) data;

/* My proposal to properly get the Window */
Window w = *(Window*) data;


Best regards,
Gregory

The documentation is slightly misleading.  What it actually means is that you're supposed to cast your window to a void pointer.

Yes I did that. It might worth to add a few line example. Thanks
Comment 3 Sam Lantinga 2012-01-07 11:06:59 UTC 
I clarified the documentation a bit.  Would you like to contribute a minimal X11 example?
