SegmentedControl and SelectSlider

Both widgets choose one value from a fixed list, but present it differently.

SegmentedControl

A row of pills inside one rounded track.

with sc.SegmentedControl(
    'View',
    options=('List', 'Grid', 'Tree'),
    value='List',
) as control:
    @control.on_switch
    def _(value):
        change_view(value)

Properties: label, options, index, value.

Signals: on_switch (the new value), value.on_change.

on_switch fires only for a user click. A programmatic value.set or index.set stays silent, so a listener can tell a click apart from a refresh.

The track hugs its options by default (width='content'). Pass width='stretch' to fill the parent.

Only single selection is implemented.

SelectSlider

A slider whose ticks are a fixed set of options.

with sc.SelectSlider(
    'Start level',
    options=range(15, 0, -1),
    value=15,
    format=lambda x: 'Lv.{}'.format(x),
) as slider:
    @slider.value.on_change
    def _():
        start_level.set(slider.value.get())

Properties: label, options, index, value.

Signals: value.on_change.

Every option is a tick on one track. Clicking or dragging to a tick selects it; the interaction is client-side and the result comes back as a change event. The slider fills its parent by default.
