选项卡式面板
TabbedPanel窗口小部件管理选项卡中的不同窗口小部件, 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。

.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' )# touse 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< 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???" ))
