How to retrieve a (MS) Windows Handler?

SDL Development
1

I’ve open a window with SDL_SetVideoMode (in MS
Windows environment). Now I want to do some operation
which requires a Windows handler. How can I retrieve
the handler of my window?

thanks

user32.lib / libuser32.a

The GetActiveWindow function retrieves the window handle to the active
window associated with the thread that calls the function.

HWND GetActiveWindow(VOID)

You should check that your window has focus before using this possibly
in combination with the SDL_APPINPUTFOCUS event.

P.S. On another note, just thinking about why one would want such a
thing might be for GUI type stuff. If that’s the case perhaps try FLTK
or wxWindows or other cross platform UI libs. There may even be some SDL
specific libs but I can’t say I know of any or how complete they are.

People may want to check this example of how to combine FLTK and SDL.
I’m a big fan of FLTK because it’s simple, small and the dimensions
don’t distort over different platforms.

Thanks for the link. But when I tried to download the
win-32 demo it was a broken link :frowning:

The source link isn’t. Mind you it doesn’t compile but might be worth a
peek around.

You can use the API in SDL_syswm.h
See the “scrap” demo on the SDL website to see how this is done.
