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?

https://github.com/DerelictOrg/DerelictSDL2
http://dgame-dev.de/

https://github.com/DerelictOrg/DerelictSFML2
https://github.com/DerelictOrg/DerelictAllegro5
http://api.gtkd.org/src/gdk/Cairo.html


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.

bye,
lobo

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

> but there is no specific solution inside GTKD?

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 :
