Hello.all,
Has anyone had any success using openGL in GtkAda ?
I tried a quick test today and although the 'Gtk.GLArea' and
'Gdk.GLContext' packages are present, I was unable to get a GL context.
Also, the testgtk program has no openGL demo, as it used to have.
I used openGL/GtkAda to good effect many years ago. Has openGL
support then been dropped completely ?
I recall there was a Gtk3 bug related to openGL and thought that
might possibly be the reason why it is absent in GtkAda. Does GtkAda use
Gtk4, yet ?
I'm quite keen to try my hand at game programming (and have
developed an Ada game engine library), so any advice/info would be
greatly appreciated.
Regards.

Rod,
GtkAda is binding for Gtk+ 3.24.x version, it doesn't support Gtk 4.
GtkAda doesn't provide OpenGL API binding, but supports OpenGL. There is no example in testgtk for this reason - it requires OpenGL API binding.

I'm very happy to report that openGL support in gtkada works fine. I
made a simple blunder in my initial test (not attaching the gl_Area
widget to my main window widget *sigh* :) ).
It is also possible to use an openGL engine (ie a renderer in it's
own ada task) with gtakada. A simple protected object to prevent mutual
access between the gtkada task (main environment task) and the openGL
engine task, is all that was required.
*Thank* you Vadim for letting me know that the openGL support is there.
Now, onto my game ! ... :D
"The game is afoot!"
Regards.
P.S. Would anyone know if gtkada might be 'upgraded' to support gtk4 ?
Just curious (gtk3 is fine for my purposes).
