Hi!
I have a situation like this

hgroup
button1
vgroup
button2
button3
end
button4
end

i would like that the height of button1 should be the same of the sum of the heights of button2 and button3. if i can make a drawing something like this:
o=button1
:=vgroup of button2 and button3
o=button4

o:o

i tried with fixed height but it gave me nothing.
the entire group is inserted in a "main" vgroup with other buttons.
just another question:
can i insert two sequential vgroup? something like this
vgroup

end

vgroup

end

THANK YOU!
