Cancel editing on a gtk.CellRendererText

[Seth Mahoney]

Hi,

I've got a TreeView that displays different kinds of data - basically book citations and plain text - in a sort of outline format.  I'd like the plain text to be editable, and the book citations to be noneditable, but I can't seem to figure out how to cancel editing.  The first column of my TreeModel contains the text to be displayed, and the second column contains xml data, which isn't displayed, but is used for a variety of purposes, including identifying the type of data.  The callback correctly prints "called!" when I try to edit a citation, but doesn't cancel the edit.  I've also tried calling editing_canceled(), but that doesn't work either.  Here's what my callback, connected to "editing-started", looks like right now:

    def outline_edit_start_cb(self, cell, editable, path, model):
        my_iter = model.get_iter_from_string(path)
        if model.get_value(my_iter, 1).tag == "cite":
            print "called!"   
            cell.stop_editing(True)
            return True
        return False

Any help would be appreciated.

I'm not sure this is what I'm looking for.  I only have one visible column, with one gtk.CellRendererText managing the whole thing.  I need a way to either get at the individual cells within the column and set the editable property there, or to cancel editing after it has begun if the data in the second (invisible) column meets certain criteria.  Thanks for the tip though.

you can set the cell as non editable. I have code as:

    if not self.fields[v]['edit']:
        try:
            cell.set_property('editable', False)
        except:
            cell.set_property('sensitive', False)

i don't remeber why I try both editable & sensitive. I guess it depends on
the type of cell renderer.
