How do I set the precise size of a Label?

the Label expands to show the text

Why would you *not* want this? It would result in text going "off the edge",
and not being readable...

fixed positions and with fixed sizes, given in pixels."

So it apparently can do exactly what I need.


Maybe I shouldn't be using Label? What's a good alternative that can indeed
be used in a Fixed with a fixed position and fixed size? I need the widget
to be able to display text and to accept events.

You seem to want a Label that may or may not display enough text to be legible, which Gtk::Fixed will do for you.  If the amount of text is variable, then it's probably wise to put it in a scrolling widget( a bog-standard TextView inside a ScrolledWindow would work nicely- as in the book).  That way when the widget is too small to make out the words, you'll still be able to scroll around.  Have a look in the manual for a working example.
If you want to capture events, you've got at least 2 options.  You can put an EventBox underneath the widget of interest- a textview or a ComboBox with entry as in the book, or you could create an empty Button and put the widget you want on it.
