I am trying to make some application using gtkd and opengl.
I have made simple program but it didn't work and I have no idea 
why.

I have never used gtk so maybe I'm doing something stupid : /

The code:

Error:

Some ideas?
Any tips to gtkd/gtk/gl are welcome.

at least one obvious error: line 37, `MyArea glarea = new 
MyArea();`

`Myarea` scope is limited to the __ctor. You should declare it as 
a class private variable and then instantiate it in the _ctor, 
otherwise. With the GC it's probably still alive til next 
collection but this is nevertheless an error.

NVM this is totally wrong. You can create an instance without 
keeping trace of it in a variable. This even something common in 
laguages using ownership and if you don't need to manipulate the 
class instance after its construction... :/

With no experience at all, copying an example without opengl from a 
basic and incomplete Turkish gtkd tutorial[1]:

import gtk.Window;
import gtk.Main;

int main(string[] args)
{
     Main.init(args);
     auto pencere = new Window("deneme");
     pencere.show();
     Main.run;

     return 0;
}

Does that work?

Yes and clear output there.
I have tried some basic examples of gtkd and they seems to work. 
GLArea has some problems.

The project has its own forum if you haven't already posted

It turns out it was caused by a bug in the gtkd.
Thanks to Mike Wey already fixed.

My minimal working code if somebody was intrested.
