Slider¶

The Slider widget looks like a scrollbar. It supports horizontal and vertical orientations, min/max values and a default value.

To create a slider from -100 to 100 starting from 25:

from kivy.uix.slider import Slider
s = Slider(min=-100, max=100, value=25)

To create a vertical slider:

from kivy.uix.slider import Slider
s = Slider(orientation='vertical')

To create a slider with a red line tracking the value:

from kivy.uix.slider import Slider
s = Slider(value_track=True, value_track_color=[1, 0, 0, 1])
