public class Slider extends Widget:

Widget

└ Slider

Integer slider widget.

The native backend forwards pointer presses and drags to setValueFromPoint, so the widget remains implemented in Klyn while only the platform event routing stays native.

slider = Slider(value=50, minimum=0, maximum=100, orientation=Slider.HORIZONTAL)
slider.trackFillColor = Color(59, 142, 208, 1.0)
slider.valueChanged += lambda(event: ValueChangedEvent): print(event.value)
