[Mono-winforms-list] OpenGL with Winforms

[Peter Dennis Bartok]

This is totally out of my area of expertise, but if I remember, all the the 
OpenGL calls are the same on Linux and on Windows, the only one different is 
the one creating the drawing context, on Linux it needs the X11 display 
handle and the drawable, where on Windows only a drawable was required.

If I recall correctly (if...), I think the post on the Tao message board 
said something on the order of looking at what Gtk does to support an OpenGl 
control (GtkGLExt I believe), and do the same thing in C#. Does this sound 
right, anybody that would know? If so, I'll take a look at it and let you 
know (and you vice versa).

If you can remember i ask for same problem at 12.10.2004:

How to link(bind) OpenGL to window, which was created with MONO SWF?

for Windows and Microsoft .NET it is not a problem:
We get a handle from window in C# code and in C++ code

void Create(HWND hwnd/*Control.Handle */)
{
  dc=GetDC(hwnd);

  int iPixelFormat = ChoosePixelFormat(dc,&rPFD);
  if(!SetPixelFormat(dc,iPixelFormat,&rPFD)) FAIL("SetPixelFormat failed!");
  if(!(hRC = wglCreateContext(dc))) FAIL("wglCreateContext failed!");
//we have OpenGL context
}

How TODO so under mono and linux?

May be you put answer to you website in FAQ?

As a side project, I'm playing around with an OpenGl WinForms
app. I have this working on Windows with both Mono and .Net. I use wgl
calls to setup a control for OpenGL rendering (very similar to what is
done for the OpenGL control in Tao). My question is, does anyone know of
where to look for similar code for Linux? I believe there used to be
something on the Tao messageboard, but that's down now. I'm guessing I
need to do some PInvokes into the GLX library, but has anyone done this
before (is it possible with Mono's SWF implementation)?

Thanks,
Jonathan
