Kivy is a platform-independent GUI tool in Python. As it can be run on Android, IOS, linux and Windows etc. It is basically used to develop the Android application, but it does not mean that it can not be used on Desktops applications.

UX Widgets:
Classical user interface widgets, ready to be assembled to create more complex widgets. There are multiple UX Widgets such as Label, Button, CheckBox, Image, Slider, Progress Bar, Text Input, Toggle button, Switch.
- Label: The Label widget is for rendering text. It supports ascii and unicode strings.
- Button: The Button is a Label with associated actions that are triggered when the button is pressed (or released after a click/touch).
- CheckBox: CheckBox is a specific two-state button that can be either checked or unchecked.
- Image: The Image widget is used to display an image.
- Slider: The Slider widget looks like a scrollbar. It supports horizontal and vertical orientations, min/max values and a default value.
- Progress Bar: ProgressBar widget is used to visualize the progress of some task.
- TextInput: The TextInput widget provides a box for editable plain text.
- Toggle Button: The ToggleButton widget acts like a checkbox. When you touch or click it, the state toggles between ‘normal’ and ‘down’ (as opposed to a Button that is only ‘down’ as long as it is pressed).
- Switch: The Switch widget is active or inactive, like a mechanical light switch.
Here, we are going to use almost all these UX widgets So that you can understand how to use them in a single code.
Basic Approach: 1) import kivy 2) import kivyApp 3) import window 4) Set minimum version(optional) 5) Create the App class 6) Create the .kv file 7) Make the run method/ run the App
Implementation of the Approach:
.py file:
Python3
# Program to Show how to use multiple UX widget # import kivy module import kivy # base Class of your App inherits from the App class. # app:always refers to the instance of your application from kivy.app import App # this restrict the kivy version i.e # below this kivy version you cannot # use the app or software kivy.require('1.9.0')# Here for providing colour to the background from kivy.core.window import Window# Setting the window sizeWindow.size = (1120, 630)# Add the App classclass ClassiqueApp(App): def build(FloatLayout): pass# Run the Appif __name__ == '__main__': ClassiqueApp().run() |
.kv file:
Python3
# .kv file implementation of the App# Using Grid layoutGridLayout: cols: 4 rows: 3 padding: 10 # Adding label Label: text: "I am a Label" # Add Button Button: text: "button 1" # Add CheckBox CheckBox: active: True # Add Image Image: source: 'html.png' # Add Slider Slider: min: -100 max: 100 value: 25 # Add progress Bar ProgressBar: min: 50 max: 100 # Add TextInput TextInput: text: "Enter the text" # Add toggle Button ToggleButton: text: " Poetry Mode " # Add Switch Switch: active: True |
Output:
