absolutely, but as we both know, it almost never honored. if resetting
the text generally led to a resize, then it would make sense. however,
i have never seen a GTK application display this behaviour, and its
not entirely clear that it would be desirable.  If you are using a
label as just as placeholder for some text, the strategy is presumably
to make sure that the usize for the label is big enough to hold the
biggest possible string, and then just change the text that is
displayed when necessary. if the widget/container heirarchy actually
implemented size changes every time the text was changed, you'd have
to explicitly put it calls to prevent this from happening or face a
very bizarre UI, no ?

Ah, perfect ... thanks.
