Tabbed panel

The TabbedPanel widget manages different widgets in tabs, with a header area for the actual tab buttons and a content area for showing the current tab content.

The TabbedPanel provides one default tab.

To use it must import :
from kivy.uix.tabbedpanel import TabbedPanel

Basic Approach:
1) import kivy
2) import kivy App
3) import floatlayout
4) import tabbedpanel
5) set minimum version(optional)
6) Create Tabbed panel class
7) create the App class
8) create .kv file:
       # create multiple tabs in it.
       # Do there functioning also.
9) return the widget/layout etc class
10) Run an instance of the class

Implementation Of Approach:

.py file

# Program to explain how to create tabbed panel App in kivy

# 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')

# to  use this must have to import it
from kivy.uix.tabbedpanel import TabbedPanel

# Floatlayout allows us to place the elements
# relatively based on the current window
# size and height especially in mobiles
from kivy.uix.floatlayout import FloatLayout

# Create Tabbed class
class Tab(TabbedPanel):
    pass

# create App class
class TabbedPanelApp(App):
    def build(self):
        return Tab()

# run the App
if __name__ == '__main__':
    TabbedPanelApp().run()

.kv file

# .kv file of tabbed panel

<Tab>:

    # creating the size
    # and the alignment of the tab
    size_hint: .5, .5
    pos_hint: {'center_x': .5, 'center_y': .5}
    do_default_tab: False

    # Create tab 1
    TabbedPanelItem:
        text: 'Tab 1'
        Label:
            text: "First tab"

    # Create 2nd tab
    TabbedPanelItem:
        text: 'Tab 2'
        BoxLayout:
            Label:
                text: 'Press button'
            Button:
                text: 'Click it'

    # Create 3rd tab
    TabbedPanelItem:
        text: 'Tab 3'
        RstDocument:
            text: '\n'.join(("How are you GFG's???"))

Output:

Tab 1:

Tab 2:

Tab 3:
