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:
http://pastebin.com/vaFAP0bu

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... :/

So no idea how to make basic gtk/opengl application working?

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?

The project has its own forum if you haven't already posted there: http://forum.gtkd.org/

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

I didn't. I will try there.
Thanks for help.

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.
