Anyone? Scripting a "hide/show"

[Louis R]

Is this even possible???

i have a rectangle (parent)
it has 3 rectangle "children" (lines go from the parent down to each of 
the three children)
i want to attach a "action" to the parent- so that when i click on it 
the children will "hide" (disapear from the canvas) clicking on it 
again will 'show' all the children

is this possible in 3.0 pro?

(i know applescript but the dictionary was too confusing)

thanks
