Just wondering does the SFML Render window allow for clearing with...

...a transparent color?

Because I'm messing with an idea of sticking an SFML window on a form and having the form itself have a full background image covering it but still having it visible through the SFML window itself too.  Or do I just make the SFML window fill the form and stick the smaller form controls on top of it for this effect?

SFML doesn't do transparent windows, no. You'll need to get OS specific for that.
I remember figuring out the way to do it for Windows (it's really simple, actually) but not sure about other systems.

EDIT: I didn't initially notice that this was in the DotNet forum. I assume that there is a DotNet version to do it that isn't far from the c++. If you can convert, or would just like a hint as to what to look for, take a look at this c++ example:
