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?
