Subject: Re: [SDL] paraGUI + OpenGL and glSDL - update and Q’s

This may be a bit off, but does anyone know of a decent GUI kit
for SDL (or OpenGL) purely written in C?

I understand it is very natural to select C++ as the language
for GUI kits, but I’d prefer something along the line in
the spirit of SDL, and C makes foreign language interfacing
much easier.

.paul.

Perhaps you should give libUFO a try.
It is (better: should be) platform independent and has
a SDL backend.

2 things:

  1. paragui nice g. I like it’s design anyways…
    The libUFO design is sympathized with Java/Swing™.
    If you don’t like it, don’t use it.

and 2: libufo breaks nicely on my computer.
Sorry, I do not get much feedback and I can only say that
it works perfectly
here.

(or usdl does. There aren’t
any libufo examples in the kit so I have no idea if it
works or not)
There are some (very old) test files in the usdl/test
directory and 8
downloadable tutorials at:
http://libufo.sourceforge.net/tutorial/

Any idea what this message means?

UButton[4,0;0x0,invalid] has no ui delegate
ULabel[“label 1” 0,0;0x0,invalid] has no ui delegate
UWidget[0,0;640x480,invalid] has no ui delegate
UButton[4,0;0x0,invalid] has no ui delegate
ULabel[“label 1” 0,0;0x0,invalid] has no ui delegate
UWidget[0,0;640x480,invalid] has no ui delegate
UButton[4,0;0x0,invalid] has no ui delegate
ULabel[“label 1” 0,0;0x0,invalid] has no ui delegate

Every widget has a UI class which is responsible for
drawing (and some event
processing).

These error messages indicate that either the UI classes
weren’t registered
at the UI manager or the widgets weren’t correctly validated.

Perhaps you could send me some system informations
(compiler, OS, …) and
your ufo/usdl version numbers (privately, as there is
enough other spam on
this list).

Thanks.

Provided you’re locking and unlocking the surfaces properly, they should work like procedural textures. This feature is not heavily tested, though, so it might just be that it’s broken… :slight_smile:

If you can’t figure it out, send me some code, and I’ll try to make it work.

yes I know this is old reply but I’ve been getting active in some devel
with paragui+opengl so I figured I’d respond :slight_smile:

There’s a couple q’s in here for folks who understand glSDL well g

on glSDL-0.3:
SDL_Surface *SDL_GetVideoSurface(void);
change to:
SDL_Surface *glSDL_GetVideoSurface(void);

on glSDL + paragui:
Display doesn’t render properly but it compiles properly. Runs
fine too with some boggles I’m still chasing down. Just doesn’t render
properly. Does glSDL have problem with surfaces that undergo changes?

It is more maintainable that way. It is hard to beat C for language
intercompatibility though.On Thu, Jun 06, 2002 at 02:10:35PM +0100, Paulo Pinto wrote:

Joseph Carter Do not write in this space

Yeah, I looked at esd and it looked like the kind of C code that an
ex-JOVIAL/Algol '60 coder who had spent the last 20 years bouncing
between Fortran-IV and Fortran '77 would write.
