remember that you can't do this until after the widget has been
realized.

however, that won't necessarily work in this case either, since a label
has no Gdk::Window of its own, so the size reported will be the size of
the parent window, which might be very very different from the size of
the label.

signal_size_allocate() can be used to find out how much space is
allocated to a widget, regardless of whether it has its own Gdk::Window
or not.

signal_configure_event() is only emitted for top level windows, since it
is related to interactions between the app, the window manager and the
window system.
