Maybe some more information would be helpful.  I am assuming the line 
drawing routine you are refering to is reacting to mouse input to draw 
the line.

If you are drawing on a canvas% I believe you would be interested in the 
on-event method, which is invoked when mouse events occur. You can have 
on-event forward its events to a mutable method which you can mutate 
with the button press callback/event.

I can describe this process in more detail if you think I am on the 
right track.
