Ever tried this: selection = treeview.get_selection() selection.set_mode(gtk.SELECTION_MULTIPLE) ? This works as you expect "out-of-the-box" (well, except deselection by a mouse click: you will have to create a callback to handle that).

OK, I knew I was making this too hard. It just took a few hours of
poring over the documentation and examples to figure *the right way*
to do it. Here is a demo script which does the multiselection using
ListStore and TreeView for the next hapless soul who passes this way
import gobject
import gtk
COLUMN_TEXT=0
# initialize the ListStore. Fom more complicated lists, see pygtk src example
# pygtk-demo/demos/list_store.py
mydata = ['John', 'Miriam', 'Rahel', 'Ava', 'Baerbel']
model = gtk.ListStore(gobject.TYPE_STRING)
for item in mydata:
iter = model.append()
model.set(iter, COLUMN_TEXT, item)
# set up the treeview to do multiple selection
treeview = gtk.TreeView(model)
treeview.set_rules_hint(gtk.TRUE)
column = gtk.TreeViewColumn('Name', gtk.CellRendererText(),
text=COLUMN_TEXT)
treeview.append_column(column)
treeview.get_selection().set_mode(gtk.SELECTION_MULTIPLE)
# when you click ok, call this function for each selected item
def foreach(model, path, iter, selected):
selected.append(model.get_value(iter, COLUMN_TEXT))
def ok_clicked(event):
selected = []
treeview.get_selection().selected_foreach(foreach, selected)
print 'And the winners are...', selected
gtk.main_quit()
# the rest is just window boilerplate
win = gtk.Window()
win.connect('destroy', lambda win: gtk.main_quit())
win.set_title('GtkListStore demo')
win.set_border_width(8)
vbox = gtk.VBox(gtk.FALSE, 8)
win.add(vbox)
label = gtk.Label('Select your firends and family')
vbox.pack_start(label, gtk.FALSE, gtk.FALSE)
sw = gtk.ScrolledWindow()
sw.set_shadow_type(gtk.SHADOW_ETCHED_IN)
sw.set_policy(gtk.POLICY_NEVER,
gtk.POLICY_AUTOMATIC)
vbox.pack_start(sw)
sw.add(treeview)
win.set_default_size(280, 250)
button = gtk.Button('OK')
button.show()
button.connect("clicked", ok_clicked )
vbox.pack_end(button,gtk.FALSE)
win.show_all()
gtk.main()

Thanks for the info.
Unfortunately, I can't see how with either of these I can create a
multiselect text list, with the ability to select and deselect text by
clicking on it. In the example below, I can select text, but cannot
deselect it, because if I click on already selected text, it is not
"changed" and hence my handler is not called. "edited" doesn't work
for me because I don't want to edit the text. "toggled" doesn't work
because I don't want users to have to check every single item -- the
list will be long with natural ranges so I want them to be able to
select a range with click item_1, shift click item_n.
Below I use treeview.get_selection().connect("changed", changed),
which has the deselection problem. Can I connect the
gtk.TreeSelection to something besides 'changed' that will be called
whenever a row is clicked. I adventurously tried 'clicked' and
'activated', but both are unknown signal names.
Where is the magic pixie dust that I am missing?

Yes, there will, as soon as my MSc thesis is delivered and I have some time to clear bugs off the backburner. Some of the heavy lifting has been done already by Johan, but I need to think a lot about CList and how to port it. There's a couple of hard problems to solve with CList, but the basic framework should be a 5-minute hack to get working. Unfortunately, my MSc is about 1 year late and the final delivery date is 10 days. I don't have much time :-( I'll be keeping the mailing list updated about my progress.

[pygtk] Setting Window Properties
Hello,
I have a question about setting the properties of a GdkWindow
with PyGTK 1.9.x.
Since PyGTK does not yet support 'skip_taskbar', I want to
set the property manually.
How can I set this property?
window.property_change("_NET_WM_STATE, "ATOM", 32,
gtk.gdk.PROP_MODE_APPEND, "_NET_WM_STATE_SKIP_TASKBAR")
does not work because PyGTK complains about the data not
being a sequence of integers...
How do I get the required integers from the string?
