Slider:
To work with the slider, you first need to import the module, which consists of all functions, functions of the slider, i.e.
Module: kivy.uix.slider
Basic approach to follow when creating Slider —
1) import kivy 2) import kivyApp 3) import BoxLayout 4) set minimum version (optional) 5) Extend the class 6) set up .kv file (name same as the Slider.kv) 7) Run an instance of the class
Below is the code that implements slider with .kv file:
| # main.py slider file
# Your application base class inherits from the application class.
# app: always refers to an instance of your application from kivy.app import App
# BoxLayout places children in a vertical or horizontal border.
# or help put the kids in the right place. from kivy.uix.boxlayout import BoxLayout
# create the root widget used in the .kv file class SliderWidget (BoxLayout): pass
# class where the name of the .kv file should be called Slider.kv.
# or create an application class class Slider (App): def build ( self ): # return a SliderWidget instance return SliderWidget ()
# run application if __ name__ = = ’__main__’ : Slider (). run () |
Now file Slider.kv : file Slider.kv
| "SliderWidget & gt ;: # create a slider Slider: # giving the slider orientation orientation: "vertical" min : 0 # minimum Slider value max : 100 # maximum Slider value value: 0 # initial Slider value # when the slider is moved to increase the value on_value: label1.text = str ( int ( self . value)) # Add shortcut Label: id : label1 font_size: "30sp" text: "0" color: 1 , 0 , 0 , 1 Slider: orientation: "horizontal" min : 0 max : 100 value: 30 on_value: label2.text = str ( int ( self . value)) Label: id : label2 font_size: "30sp" text: "30" color: 0 , 0 , 1 , 1 |
Output:
