Re: [Sc-devel] .clear .. again sorry

[Jan Trutzschler <sc3@xxxxxxxxxxxxxxxxx>]

Hi Thor,
i committed a method called clearDrawing, please check if this does  
what yo would expect. Btw. it is enough to refresh the SCUserView,  
you don't have to refresh the whole window each time.
Best,
Jan

(
var dropcount, drawer;
dropcount = 16;
c = true;
a = Array.fill(dropcount, {80.rand});
	
	w = SCWindow("drops", Rect(211, 311, 820, 343)).front;

	~drawer = SCUserView(w, Rect(120, 5, 680, 200))
			.canFocus_(false)
			.relativeOrigin_(true)
			.drawFunc_({ |view|
				if(c == true, {
					\drawing.postln;
					Pen.color = Color.rand;
					16.do({ |i|
						a.do({ |steps, ix|
							steps.do({ |iy|
								Pen.line(
								Point(	(ix*(680/dropcount)),
										3.5+(((iy+1)*(192/steps))).round(1)),
								Point(	(ix*(680/dropcount))+(680/dropcount),
										3.5+(((iy+1)*(192/steps))).round(1))
								);
							});
						});
					});
					Pen.stroke;
					c = false;
				});
			})
			.clearOnRefresh_(false);
)

// run the following 3 lines a few times.
// I need to be able to clear when I want, but still no refresh
c = true
a = Array.fill(16, {80.rand});
w.refresh;
~drawer.clearDrawing;
