Hi,
In wich Unit is the function Intersectrect (http://lazarus-
ccr.sourceforge.net/docs/rtl/types/intersectrect.html)

Because when i use Intersectrect, i get Identifier not found
"Intersectrect". 

Thanks!

And what is the third/first rectangle good for?

I don't understand.

IntersectRect returns the intersection of the 2 rectangles R1 and R2
in Rect. It returns True if the 2 rectangles have an intersection,
otherwise False is returned, and Rect is filled with zero.

QuoteAnd what is the third/first rectangle good for?The explanation is
clear. 2nd and 3rd parameter is intersected and the resulting
intersection rect is placed in 1st parameter.
