Pixelbuffer to draw on a surface

[TheDGuy via Digitalmars-d-learn]

Hi,
is there any possibility, to draw with a pixelbuffer to a surface 
(for example with GTKD) and to update it every few milliseconds?

Are any of these suitable for your needs?

I'm using DerelictSDL2 and Dgame for small 2D hobby games and 
loving it. Haven't used the others for D pixel rendering but I'm 
sure they're fine too.

Thanks for your answer,
but there is no specific solution inside GTKD?

As I know cairo is a part of GTK, so you consider using cairo as a
specific solution.

*you can consider

for example, in pseudo code

auto surf = new Surface(...); // look for cairo.Surface doc
auto cr = cairo.Context.Context.create(surf);

// pb is an existing gdkpixbuf.Pixbuf
gdk.Cairo.setSourcePixbuf(cr, pb, width, height);
cr.paint();

adding onDraw event listener on the widget owner of the Pixbuf 
(gtk.Image for example)

Thanks for your answers. I think Cairo is the right way but i 
have a hard time to translate any of those C++ or Python 
tutorials to D, my current code:


import gtk.Main;
import gtk.MainWindow;
import gtk.DrawingArea;
import gdk.Cairo;
import gtk.Widget;

void main(string[] args){
Main.init(args);
MainWindow win = new MainWindow("Tutorial");
win.setDefaultSize(250,250);

win.add(new MyArea());
win.showAll();
Main.run();
}

class MyArea : DrawingArea
{
this(){
}

bool on_draw(){

return true;
}
}

I tried to work with this Python tutorial (i think Python is 
easier to read than C++):

http://www.tortall.net/mu/wiki/PyGTKCairoTutorial

but if i try to do this: "cr = self.window.cairo_create()" i get:
"No property Window for type main.Area"?

gtkd demos for examples, might be of interest, like clock :
