RE: how to justify text in a GtkTextView -- workaround

["Boncek, John" <jboncek Hunter COM>]

A work-around for this in GTK 2.2.4 has been found.  Adding the line

        gtk_text_view_set_wrap_mode(view, GTK_WRAP_WORD);

just before the call of gtk_text_view_set_justification causes the
justification to work.  A co-worker reminded me that we had seen similar
behavior -- Pango layout center and right justification only works when
wrapping is turned on.

Indeed it does.  Thanks.  I get it all the way at the left edge running on
both SuSE 9.1 and on MontaVista Linux.  May be a bug in 2.2.4.
Unfortunately, it may not be practical for me to update to a later version
any time soon.

I have attached a snapshot of your test program. Looks centered to me. 
I'm using Gtk 2.4.10.
