When you REALLY need this, you may try the GTK Fixed container.
It allows to position widgets at absolute positions, and at the same
time, it prevents widgets from expanding itself.

Try the Ruby code below -- for me it always displays "Not a..." even
when I resize the main window. Of course you may read the documentation
of the Fixed container.

require 'gtk3'

window = Gtk::Window.new
window.border_width = 10
window.set_default_size(80, -1)

window.signal_connect("destroy") {Gtk.main_quit}

f = Gtk::Fixed.new
l = Gtk::Label.new('Not a long text')
l.set_size_request(50, -1)
l.ellipsize = Pango::ELLIPSIZE_END

#f.put(l, 0, 0)
f.add(l)

window.add(f)
window.show_all

Gtk.main
