Thanks a lot for that! You saved me an hour or more of working on an ugly hack
around this.
I am in fact creating objects dynamically, and the code wasn't working, like
you implied. However, I checked the manual, and it seems like you should use
the start block inside the stack/flow block, and you hand it the stack object
in the start block. Then it works. Here's the example code, which does what I
wanted (the rectangle is drawn to fit in the stack), click to see it work:
Shoes.app do
def omg
stack( :height => 70, :width => 200 ) do
border black
start do |stacky|
stacky.append do
nostroke
fill( rgb( rand, rand, 1.0, 0.5 ) )
rect 0, 0, stacky.width, 25, 10
para "This slot has some height and width, surely?"
end
end
end
end
click { |button,left,top| omg }
end
