Kivy python create a tab bar

[huit...@gmail.com]

I started with kivy, I have generally understood the main concepts (it's quite similar to tkinter)

but there is something that I can not do, I would like to create a tab bar at the top of my window (as there is in the web browser)

The only tutorial I find does not look like my code: https://kivy.org/docs/api-kivy.uix.tabbedpanel.html

my code:

from kivy.app import App

from kivy.uix.button import Button

from kivy.uix.label import Label

from kivy.uix.boxlayout import BoxLayout

from kivy.uix.textinput import TextInput

class MyApp(App):

# layout

    def build(self):

        layout = BoxLayout(orientation='vertical')

        # use a (r, g, b, a) tuple

        blue = (0, 0, 1.5, 2.5)

        red = (2.5, 0, 0, 1.5)

        btn =  Button(text='Touch me!', background_color=blue, font_size=120)

        btn.bind(on_press=self.callback)

        btn2 =  Button(text='btn2', background_color=red, font_size=120)

        layout.add_widget(btn)

        layout.add_widget(btn2)

        self.label = Label(text="------------", font_size='50sp')

        layout.add_widget(self.label)

        btn1 = Button(text="OK")

        btn1.bind(on_press=self.buttonClicked)

        layout.add_widget(btn1)

        self.lbl1 = Label(text="test")

        layout.add_widget(self.lbl1)

        self.txt1 = TextInput(text='', multiline=False)

        layout.add_widget(self.txt1)

        return layout

    def callback(self, event):

        print("button touched")  # test

        self.label.text = "button touched"

# button click function

    def buttonClicked(self,btn):

        self.lbl1.text = "You wrote " + self.txt1.text

# run app

if __name__ == "__main__":

    MyApp().run()

I try to add tabpannel but i have two question :

1) how can i change name of tab ? and remove "defaulttab"

2) why my widget not in my tab ?

from kivy.app import App

from kivy.uix.button import Button

from kivy.uix.label import Label

from kivy.uix.boxlayout import BoxLayout

from kivy.uix.textinput import TextInput

from kivy.uix.tabbedpanel import TabbedPanel

from kivy.uix.tabbedpanel import TabbedPanelItem

class MyApp(App):

# layout

    def build(self):

        layout = BoxLayout(orientation='vertical')

        # use a (r, g, b, a) tuple

        blue = (0, 0, 1.5, 2.5)

        red = (2.5, 0, 0, 1.5)

        tab=TabbedPanel()

        tabitem=TabbedPanelItem()

        tab.add_widget(tabitem)

        layout.add_widget(tab)

        btn =  Button(text='Touch me!', background_color=blue, font_size=120)

        btn.bind(on_press=self.callback)

        btn2 =  Button(text='btn2', background_color=red, font_size=120)

        tabitem.add_widget(btn)

        tabitem.add_widget(btn2)

        self.label = Label(text="------------", font_size='50sp')

        tabitem.add_widget(self.label)

        btn1 = Button(text="OK")

        btn1.bind(on_press=self.buttonClicked)

        tabitem.add_widget(btn1)

        self.lbl1 = Label(text="test")

        tabitem.add_widget(self.lbl1)

        self.txt1 = TextInput(text='', multiline=False)

        tabitem.add_widget(self.txt1)

        return layout

    def callback(self, event):

        print("button touched")  # test

        self.label.text = "button touched"

# button click function

    def buttonClicked(self,btn):

        self.lbl1.text = "You wrote " + self.txt1.text

# run app

if __name__ == "__main__":

    MyApp().run()

You have to set this to make default tab go away do_default_tab: False 

[huit...@gmail.com]

Yes but i don't want use kt text, how for example can i transform do_default_tab: False

to my code ?

[Dipanshu Juneja]

tab = TabbedPanel()
tab.do_default_tab = False

should work
