No,
     what Chao wants is to streach out the text in a label
to match the size he's decided the label is going to be.

The problem with this is that its completely backwards (not
impossible, just backwards)... gtk+ has a good reputation for
producing well resizable applications, and the thing that mostly
defines how much space a widget will take, is the text size inside
the widget, and that is always locale specific etc etc.

So to sum it up, generally GTK+ uses the rendered text size of a label
to produce a size request in an innermost child in the hierarchy.. that
size is propagated up through the heirarchy and computed against
container properties such as border-width etc... untill every widget
recieves its proper size allocation.

Label streaching could be achived by explicitly setting the size-request
of the widget you are rendering text to, and then doing some pango/cairo
magic to render the text on that widget.

But judging from the initial posts in this thread... I have to ask,
why on earth would you want to streach the labels in a table to look
more uniform ? why not justify/align them centered ?

I've seen some strange UIs that have followed the misconception that
streaching-to-fit thier labels were going to make the app look more
balanced, it looks seriously all out-of-whack if you ask me.
