Hello,
Is there no way to display your sdl surface on a form that you create with
another tool??
I’ve now read the sdl help file and faq cover to cover, and if I understand
correctly, the sdl makes it’s own window, and the sdl surface is all that
you can have in that window, without platform specific hacks. Borlands clx
library makes cross platform forms, and I’d like to create an application
that uses both… but when I try, all I get is two windows with two taskbar
buttons that work totally seperately as far as focus, input etc.
Also no one on here has answered my original email about this from last night yet, won’t anyone help out a person new to the sdl?
Sometimes takes awhile to get a decent response, unforunately. I’ll do my best…

There is no way to do this that is standard, crossplatform, and/or stable. SDL is simply not designed to co-exist inside something
else’s window, it makes it’s OWN window. That said, there are a variety of GUI libraries for SDL you can find on www.libsdl.org/libraries.php to do GUI stuff within your SDL window…
Perhaps he didn’t ask the right question. I certainly want to be able to
have my OpenGL surface use only part of an SDL window, leaving me free to
draw into the remainder in any way I choose, including with various kinds of
widgets. I’d be surprised if there’s any insurmountable obstacle in the way
to doing this cross-platform (please surprise me if there is).
I just checked, and Mesa is quite happy to use less than the full SDL window
for its viewport. However, I notice that the remainder of the window gets
cleared to my glClearColor, which means somebody is blitting a part of the
screen they ought not to, which would definitely screw up this idea. It
looks like Mesa is the culprit, but I haven’t done much digging yet. It seems
fundamentally broken for OpenGL to be drawing anything outside its viewport,
or for SDL to flip anything to the screen that’s outside the viewport.
There are numerous examples out there of OpenGL and various kinds of native
widgets existing in the same window, so I’d expect that SDL could be made to
do this as well. I suspect Sam just hasn’t gotten around to it, since you
don’t really need this for a game. But if you want to make something like
Maya, then you need it really badly.
