Hi, <div>2007/11/8, Pat Kane <<a href="mailto:pekane52@gmail.com">pekane52@gmail.com</a>>:<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> The "libwnck-2.18.3" source distro has docs and a couple of interesting test programs that appear to do what you need to do. The "test-wnck" program puts up a gui with check boxes that can be used to do window-manager-ish things. </blockquote></div> okay, that's cool, thanks. libwnck has a lot of dependencies to libraries such as Gtk, Pango and Cairo, so I won't be using it directly, but I already learned some interesting things just by browsing its sources. I think what I'll be doing is to merely use it to check how the some of the desired functionality is achieved and implement something equivalent for our small wrapper. I just don't want to have a bunch of GNOME dependencies I don't need anyway. Most things are one-liners anyway, but as an X11 beginner I just needed some pointer on how to communicate with the X server, e.g. what messages I have to sent in order to make the window manager perform action X.
