SDL Development
1

Hello

the following code :

Code:
SDL_SetVideoMode(640, 480, 32, SDL_HWSURFACE | SDL_NOFRAME );

create a standard square black window with no frame.

i want to create a custom shape window (not a square window or a transparent window) with sdl, i couldn’t find out how to make that. that seems to be possible with win32 api, however i need to do it in sdl.

can anyone help me please ?

thank you

You can fetch the windows window information (window handle, etc) from SDL using SDL_GetWMInfo (http://www.libsdl.org/cgi/docwiki.cgi/SDL_GetWMInfo)

Dunno if there’s an equivalent function for SDL 1.3, but it should be in the compatibility layer anyway.

thanks for this help

no much documentation on SDL_GetWMInfo, i’m not sure how to use it [Embarassed]

let me guess, SDL_GetWMInfo allow to get win32api handle, then should use some win32api code to make window transparent ?

isn’t there a better way to do that in sdl ?

This is a planned feature for SDL 1.3, but not yet implemented.
I believe the idea is to have an alpha channel on the window itself, but I’m
not sure how that works if you’re using the renderer API rather than
surfaces.
