Why do it need Windows.Forms?
In C/C++ you can program with GLUT platformindepoendent.
And if you want to use glx.h or wingl.h instead of this, you can integrate 
OpenGL in _any_ GUI!
In C/C++ it was integrated in Gtk+, Qt and FLTK, Fox, etc.
Why need the C#-Binding a special GUI?


>  There are plans to use Wine or GTK to do it.

But why do you need this GUI?
With GLUT it can run platformindependent.
And _if_ it is hard to integrate OpenGL in the special GUIs, _than_ it is 
the job for the Gtk#-Team, Qt#-Team or Mono-Winforms-Team.
But it is the job of the CsGL-Team to make the CsGL for any platform and any 
.net-implemenatation avaible. And this is possible - with GLUT. GLUT is 
platformindependent. That OpenGL and special GUIs work together, is _not_ 
the job of CsGL - I think.

And _why_ depends it on Windows.Forms?

Have you a link to your post there?

Yes. But if it is a hard work, it is the job of the Gtk#-Team.
But why does CsGL not running _without_ any special GUI on Mono/Linux?

Hmmm... and do you know _why_ Gtk# makes everything static?
And there was a time (older Gtk#-Version), where it was not so?
Thats something, what someone can ask in the Gtk#-list.

I hope so.

Hi Michael!

Sorry, that I answer so late.

Why does GsGL need Windows.Forms?
I thought OpenGL is platform-independent. Why does ist then need a special 
GUI?


>I had asked this question to Lloyd on the sourceforge forum

And dou you have the link to the thread in the forum, where your question 
stand?


>and he said that it might be possible to use the GtkSharp library to
>do windowing instead of the Windows.Forms,

But why need CsGL a special GUI for Windowing?
With GLUT you can in C/C++ program platformindependent - and you don't need 
any GUI.
Why do you need it for CsGL?

I think, it is the job of the CsGL-Team to create OpenGL-Bindings, so that 
it run on every platform.
And it is the job of the GUI-Teams (like Gtk#, Qt#, etc) to integrate it in 
thier GUI.

Thats the same like in C/C++:
OpenGL is with GLUT platformindependent. And if you want, you can integrate 
it in your Gtk+-, Qt-, FLTK- or Fox-programs.
But why is it so hard unter C# ?


>Since GtkSharp requires the use of making everything static, it is

For this I have now asked the Gtk#-Team under
http://lists.ximian.com/archives/public/gtk-sharp-list/2002-December/000627.html
why it is so.

>Maybe, Lloyd can shead some light on the issue.

I hope so.

Thanks.

Re: [Csgl-users] CsGL and Mono

[Lloyd D. <ll...@ga...>]

Hi,

First I want to say I didn't use GLUT at all.
I write CsGL to be very neatly integrated in the System.Windows.Form
hierarchy.
In my mind a GL control should be just like any other Control.

And here it is, you just create an OpenGLControl, a subclass of
System.Windows.Forms.Control, a good citizen in WinForm population. So you
do need WinForm.
I know I write it !

And you could put as many OpenGLControl in you .NET application as you want,
and wherever you want. (in a Button ?) try to do that with GLUT !

However it's very modular, the OpenGLContext, the crucial and only OS
dependant OpenGL object doesn't depends on Winform. With a minimal amount of
work you could do a Gtk#, or GLUT version of it.

BTW, if I had to choose a multiplatform environment to write an GLControl, I
had choosed SDL (http://www.libsdl.org) library (not GLUT). But I didn't do
it because WinForm has many advantage over SDL (yet), Winform could have
mutliple windows ! Winforms could have transparent and odly shaped window !
SDL cannot do the above.

Anyway, now I have a good network (at last, just recently) and I will try to
upgrade CsGL to mono/FreeBSD as soon as possible,

Cheers,
Lloyd

PS: BTW I don't know about Gtk# and I don't think I will have the time to
investigate...
:-(
I will wait and go for mono/Winform.
