选项卡式面板

TabbedPanel 小部件管理选项卡中的不同小部件，具有用于实际选项卡按钮的标题区域和用于显示当前选项卡内容的内容区域。

TabbedPanel 提供了一个默认选项卡。

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

方法的实施：

.py 文件

# 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 文件

# .kv file of tabbed panel
  
:
  
    # 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???"))
