[Visualpython-users] simplest way to determine if mouseclick is in the corner of a box ?

[Stef M. <s.m...@ru...>]

hello,

probably another simple question (for those who are  known with vector 
algebra),
how do I determine if I click in the corner region of a box or somewhere 
on the middle.

the idea is that dragging,
-  should rotate the box if the start drag is in the corner
-  should move the object is hit some where in the middle

thanks,
