How know if a stack is maximized ?

[GIRARD Damien]

Hi all,

I am searching, but I don't find anything now.
Does there is a function in Runrev that permit to know if a stack is 
maximized or not ?

Or do I have to do a trick like ever ?
(if the rect of the stack look like to be maximized, it is maximized).

Thanks,

Damien
