Filechooser:
The FileChooser module provides various classes for describing, displaying, and browsing file systems. It is Simple like the My computer from where we can choose any file in the system.
- The FileChooserListView displays file entries as text items in a vertical list, where folders can be collapsed and expanded.
- The FileChooserIconView presents icons and text from left to right, wrapping them as required.
Note: The both above points provide for scrolling, selection and basic user interaction.
Basic Approach
1) import kivy
2) import kivyApp
3) import Boxlayout
4) Set minimum version(optional)
5) create layout class
6) create App class
7) create .kv file
8) return Layout/widget/Class(according to requirement)
9) Run an instance of the class or App
Implementation of the Approach:
.py file
Python3
import kivy
from kivy.app import App
kivy.require('1.9.0')
from kivy.uix.boxlayout import BoxLayout
class Filechooser(BoxLayout):
