You could try getting the size of the widget the context is referring to 
with getAllocation.

GtkAllocation size;
widget.getAllocation(size);

and then use size.width and size.height.

Thank you very much for your answer! I really appreciate it 
because it is kind of hard to find explanations for GTKD.

But know i face a strange problem:

	this(Vector3D camera, Context cr, Widget widget){
		this.camera = camera;
		this.cr = cr;
		this.widget = widget;

		GtkAllocation size;
		widget.getAllocation(size);
		this.width = size.width;
		this.height = size.height;
	}
	void restartProgressiveRendering(){
		int[this.width*this.height*3+1] space;
		this.accumulator = space;
	}

I get the error "value of 'this' is not known at compile time" 
which refers to the line where i create the int-array "space"
Why is it not possible to use it there?

By Adam D. Ruppe:

"
Try:

auto arr = new int[](size.width*size.height*3+1);

The int[x] syntax declares a statically sized array - statically 
sized meaning it must be known at compile time and thus cannot be 
variables, along a few other differences.

The new array syntax though returns one of variable size.
