Python treeview update tag

Question

I have inserted items into a Python treeview with tag option.

tree.insert("", 'end', 'item1', text='item1', tags=('new',))

Is it possible to change the tag "new" to something else later?

Answer 1

You can modify any of the options of an item. So if you want to change 'item1' tags to for example 'old':

tree.item('item1', tags=('old'))

From Python docs about ttk.Treeview:

item(item, option=None, **kw) Query or modify the options for the specified item.

If no options are given, a dict with options/values for the item is returned. If option is specified then the value for that option is returned. Otherwise, sets the options to the corresponding values as given by kw.
