If the mouse pointer is over the arrow, the scroll arrow is highlighted, if this happens, all other mouse events should not be executed.
My problem is that I can also draw a line by mouse at this point, but so that this does not happen, when the scroll arrow is pressed, I must be able to stop my draw line function.
I have made a short video, you can see exactly what I mean: http://www.youtube.com/watch?v=qR9xulXSeJ8
Does anyone have an idea?
