I'm posting in the Max forum since I think my question is more about programming that about Jitter-specific stuff.

I found this helpful patch (below) in the forums, and slightly modified it to draw and display in the same pwindow. What happens now is that a rectangle is calculated to the dimensions of a drag length x and y while the mousebutton is down, and then drawn on the release of the mouse button.

What I'd like to have happen is for the rectangle to draw dynamically as the mouse is being dragged, then to stay drawn in the pwindow after the button is released.

Any recommendations on how I could make that happen?

Here's a start. If you want to draw multiple rectangles, you should buffer the matrix when the mouse button goes down, and then draw it back in when the button comes up. Does that make sense?

I added the buffer function. I decided it would be more efficient to buffer the messages to jit.lcd:
