Tabs

A tab bar with one panel per label.

with sc.Tabs(('Overview', 'Details')) as tabs:
    with tabs['Overview']:
        sc.Text('Summary')
    with tabs['Details']:
        sc.Text('Full details')

Properties: active.

Signals: active.on_change (tabs['on_active']).

Addressing panels

with tabs['Overview']:
    ...

# or in label order
with sc.Tabs(('a', 'b')) as tabs:
    with next(tabs):
        ...
    with next(tabs):
        ...

tabs[label] returns that label’s panel, creating it on first access and reusing it afterwards. Panels are built up front; switching tabs is entirely client-side.

Label collisions

A label wins over property access. A tab named active is not reachable as tabs['active']; read the property through tabs.active instead.

Programmatic switching

tabs.active.set('Details')

The client switches to that panel on the next patch.
