Elements can be appended to stacks and flows without altering the other elements already present. The append method does this, and it takes a block defining the elements to append.
Shoes.app :width => 200, :height => 140 do
@times = 0
stack do
button "Press me" do
@times += 1
@p.append { para "You pressed me #{@times} t imes" }
end
@p = flow
end
end
Similarly, the prepend method can be used to add elements to the beginning of the stack or flow.
