I have created a simple treestore, with each node containing two strings, ie:
self.wTreeModel = gtk.TreeStore(gobject.TYPE_STRING, gobject.TYPE_STRING)
and allowed multiple selection with:
self.wTreeSelection = self.wTreeView.get_selection()
self.wTreeSelection.set_mode(gtk.SELECTION_MULTIPLE)
and then populated it with something like:
child = self.wTreeModel.append(parent, [<a string to display on
the tree>,<some data associated with that row> ])
all well and good; the tree shows up correctly in the window.
But now I want to be able to select one or more of the rows in the
tree, then get back the<some data> associated with each row. I have
tried something like:
treeSelection = self.wTreeView.get_selection()
model, selected = treeSelection.get_selected_rows()
for path in selected:
for i in range(len(path)):
it = model.get_iter(path[i])
print model[it][1]
There's something wrong with how you get the data here. You pass an iter
where you need a path.
Try this:
for path in selected:
print model[path][1]
A path is a row, so for every row in the selected rows, get the row in
the model (model[path]) and retrieve the data from the second column
([1], zero-based).
To get the data with an iter, you could do this:
for path in selected:
rowiter = model.get_iter(path)
print model.get_value(rowiter, 1)
This is more useful when you have a single selection treeview and use
get_selected(), because that will return an iter of its own.
model, rowiter = selection.get_selected()
data = model.get_value(rowiter, 1)
Cheers,

which I feel should print the<some data> for each selected row, but
what actually comes out seems largely unrelated to what has been
selected. So for instance, given a tree:
one --
|-- two --
|-- three
I should be able to select "three" and get back the data associated
with it. What I actually get back from the above bit of code is the
data associated with "one", three times.
Any help would be greatly appreciated!
