Re: [Sc-devel] relative coordinates in SCUserView

[Jan Trutzschler <sc3@xxxxxxxxxxxxxxxxx>]

getting the normalized position is fairly simple. it would like this:

(
var w;
w = SCWindow.new.front;
SCUserView(w, w.view.bounds)
	.mouseMoveAction_{|v, x, y|
		"normalized position %".format((v.mousePosition /  
v.bounds.extent)).postln;
		"relative position %".format(v.mousePosition).postln;
		"absolute position %".format((x@y)).postln;

	}
)
