I can get it to draw after the drag --- but not WHILE the mouse is being dragged. I'm a bit new to Processing and am thinking this has something to do with pushing things to a matrix? Thanks for your help.

It works-- but draws a series of rectangles -- not one progressively: Code: void draw(){  onOff=false;  if ((keyPressed) && (key=='s')){    onOff=true;    moveX=mouseX;    moveY=mouseY;             noFill();      stroke(grayLine);    rect(click.x, click.y, moveX-click.x, moveY-click.y);    }
