gnome-specimen r13 - in trunk-from-bzr: . glade

[wbolster svn gnome org]

Author: wbolster
Date: Tue Jun 17 18:41:26 2008
New Revision: 13
URL: http://svn.gnome.org/viewvc/gnome-specimen?rev=13&view=rev

Log:
* glade/gnome-specimen.glade:
  - Removed the preview label and put a listbox in its
    place.

* specimenwindow.py
  - Initialize the previews treeview. Each preview uses two
    rows: one shows the font name, the other contains the
    actual preview label.
  - Added add_preview
  - Set a data handler to handle the preview cell rendering
