Hi all,
I've got the mouseclick handler correctly set up. I have a drawing with some shapes. Is there any way for me to fill the surrounding part of a point until it hits a polygon boundary. Something like Microsoft Paint's "fill" command.
Thanks!

...but what about the previous round parenteses surrounding all the function.
Of parentheses surrounding the function definition is the function itself which, indeed, the second set I learnt very-very much.
