Below code draws an arrow between mouseDown point and mouseUp point. It works well. But arrow displays only after mouseUp event.I want to display arrow during moving of mouse (before I do mouseUp). I think I have to add "something" to mouseMoveHandler(). But didn't know what? Can someone tell me how can I do this?
