i'm sorry because i did not understand your question right and
therefore gave a answer that was not helpful. Anyway, I am not an
expert in FXRuby. lyle is the real expert. i am just trying my best to
give my experience to people who are new to FXRuby.

i also often had the problem that a widget did not give back it's real
size but 1x1 instead. maybe making a layoutcontainer (verticalframe or
packer) around the imageview might help. then you can get the
containers width and height.

they are not at all annoying. ;)
