lib/7-0-0-0/examples/. You can simply evaluate the given form to view the example source file.
1.2.3 Appearance of the graphical tools
Screenshots in this manual show the KnowledgeWorks tools running on Linux under GTK+ with a particular window manager and theme. So if you use GTK+ with a different window manager or theme, or Motif, you should expect a different appearance from that depicted here.
The screenshots in this manual show toolbars that may have been customized (using the context menu) so you might see some differences from your setup.
