Slider

Bases: SliderWidget[int]

A slider widget to adjust an integer value within a range.

Parameters:

• value (Any, default: Undefined ) –

  The starting value for the widget.

• min (float, default: Undefined ) –

  The minimum allowable value, by default 0 (or value if value is less than 0)

• max (float, default: Undefined ) –

  The maximum allowable value, by default 999 (or value if value is greater than 999)

• step (float, default: Undefined ) –

  The step size for incrementing the value, by default adaptive step is used

• orientation ((str, {'horizontal', 'vertical'}), default: 'horizontal' ) –

  The orientation for the slider, by default "horizontal"

• readout (bool, default: True ) –

  Whether to show the editable spinbox next to the slider

• tracking (bool, default: True ) –

  If tracking is enabled (the default), the slider emits the changed signal while the slider is being dragged. If tracking is disabled, the slider emits the changed signal only after the user releases the slider.

• bind (Callable[[ValueWidget], Any] | Any, default: Undefined ) –

  A value or callback to bind this widget. If provided, whenever widget.value is accessed, the value provided here will be returned instead. bind may be a callable, in which case bind(self) will be returned (i.e. your bound callback must accept a single parameter, which is this widget instance).

• nullable (bool, default: False ) –

  If True, the widget will accepts None as a valid value, by default False.

• **base_widget_kwargs (Any, default: {} ) –

  All additional keyword arguments are passed to the base magicgui.widgets.Widget constructor.
