Gtk.ProgressBar:ellipsize

"ellipsize"             Pango.EllipsizeMode                : Read / Write

The preferred place to ellipsize the string, if the progress bar does not have enough room to display the entire string, specified as a Pango.EllipsizeMode.

Note that setting this property to a value other than Pango.EllipsizeMode.none has the side-effect that the progress bar requests only enough space to display the ellipsis ("..."). Another means to set a progress bar's width is Gtk.set_size_request.
