Re: How to use OpenGL with Gtkmm 3?

Hello everybody out there!

        When you look at GtkGlExt-list archive (e.g.
<http://www.mail-archive.com/gtkglext-list gnome org/index.html>), you
can see there has been some discussion about a version of GtkGlExt for
Gtk+ 3. According to the Git repository (e.g.
<https://github.com/tdz/gtkglext>), last changes in development version
has been made nine months ago.

        This project is probably not dashing, but it may be a bit too rush to
call it dead just now.

SFML is definitively a very good library, but it is not dedicated to
OpenGL (though it do it very well). It comes with much more. Depending
on what you are doing, it may be an advantage, or not.

        Also, GtkGlExt (and GtkGlExtmm) can give OpenGL capability to any
widget. I guess not many are using GtkGlExt on something else but a
drawing area, but this is still an interesting feature. While SFML is
not just a drawing library, it would be pointless to give SFML
capability to any widget.

        Therefore, this is a good thing to have SFMLWidget, but GtkGlExtmm can
also be quite useful. As far as I know, there is not that much to be
done to get a stable version of GtkGlExt being compatible with Gtk+ 3
and OpenGL 3 and 4. But it seems that developers whom have been involved
in GtkGlExt development cannot finish the work to be done – whatever the
reason, this is open software and mostly voluntary work, there can be
several very good reasons for this.

        I plan to volunteer in participating in GtkGlExt development, even to
become maintainer if needed. But, I will be busy on several other things
until the end of this month, and I still have to self train on Gtk+
internals before being efficient.

        Best regards.
