digitalmars.D.learn - custom drawing with gktd?

I have a need to draw custom objects with gtkD, is this possible? 
I see that with drawing area one can use cario, and it seems that 
gtkD supports this. I'd rather use openGL if possible. I see 
there is a gtkDGL but no reference to how to use it.

I need pretty simple drawing stuff... lines, icons, maybe 
images(which, I guess, I'll have to use an external lib to load 
the images).

Thanks.

For openGL it would be better to use gtk.GLArea, which is included in gtk since 3.16. You can use the GLCore demo as an example: https://github.com/gtkd-developers/GtkD/blob/master/demos/gl/core/CoreGL.d GtkDGL wraps gtkglext3 which is currently not maintained, and no longer has any binaries available. -- Mike Wey

Thanks, I'll try it.
