Oh, I see. The main reason is that on GNOME 3.4 I'm happy for all
configuring to be done via gnome-shell-extension-prefs but on GNOME
3.2 would like configuring to be done via the drop down menu from the
status icon (since it'll have one anyway). However I'm after a few
more complex widgets that won't work in PopupMenu (like Gtk TreeView),
so have to work out how to get the TreeView happening from the
PopupMenu for the GNOME 3.2 folk (I know 3.2 is going out of fashion
pretty quickly due to 3.5 coming out, but I personally am going to be
stuck on 3.2 for at least another year at work so it's important for
me that extensions work on the computer I spend the most time on!)

So the options for getting (e.g.) Gtk.TreeView from a PopupMenu/GNOME
3.2 (I mainly want to use it as a list box where each item is
editable; the add/remove functions are not important), what I've
thought of so far:

* a PopupMenuItem ("Prefs") launches a GTK widget with the TreeView in
it - I now know it will have to spawn an external process to do so.
* make a PopupMenuItem for *each* of the entires that I wanted in my
TreeView, and say clicking them brings up a modalDialog with a
St.Entry for the user to enter in a new name
* a PopupMenuItem ("Prefs") brings up a modal dialog where there's one
non-editable St.Entry for each of the entries and perhaps a St.Button
next to each ("Edit") that allows me to edit each entry

Are these basically my only options? (I think the
St.Entry/PopupMenuItem-per-entry solution feels pretty cludgy).
