Transparent Window

SDL Development
1

Hi All,

This is my first post to the list. I am after creating a window, on windows, which is transparent. I want to be able to see the desktop through this window but at the same time be able to render to this window. I would like to be able to do this all within SDL, is this going to be possible?

Thanks, Andy

look for SDL_CreateShapedWindow in sdl sources, maybe you can find the info you need there.
I am not sure about the Shaped windows current status, though.

SDL_CreateShapedWindow applies a bitmask to a window for pixel-level
on/off transparency. Last time I checked (i.e. during GSoC 2010 as
mentor) it worked on X11, works on Win32 (but doesn’t create the shape
entirely correct) and doesn’t work on OSX (shape not applied for unknown
reasons).On 2/19/12 9:34 AM, RodrigoCard wrote:
