setting sizes, interface too slow?

[thorvang]

i'm setting the size of one widget within a onShow event and right after that setting the size of another widget to the size of the previously set widget (next line of command in the same event).

but somehow the second widget always receives the size of the first widget prior to resizing. is this caused by the UI not responding that quick or what is it?

(edited to clarify)

it's two nested widgets. the inner one is sitting with packsize=proportional inside the outer one. i resize the outer one and want another widget set to the size of the now automatically resized inner widget. and that's what not functioning.
