Thanks! The get_value() answered half of my question. Now I can get the
contents of a cell.
The other half is complicated by the fact that I use SELECTION_MULTIPLE,
during which I cannot use get_selected. I can iterate over the selection,
but I've found no easy way to check if there is a selection at all. Right
now I'm resorting to the following hack:
any_output = False
def output_line(model, path, iter, file):
...output stuff...
any_output = True
return False
def output_to_file(file,treeview):
any_output = False
selection = treeview.get_selection()
selection.selected_foreach(output_line, file)
if (not(any_output)):
model = treeview.get_model()
model.foreach(output_line, file)
Not pretty, but it gets the job done.
