Question

我从kivy开始，我一般都了解主要概念（它与tkinter非常相似）

但有一些我不能做的事情，我想在我的窗口顶部创建一个标签栏（就像在网络浏览器中一样）

我发现的唯一教程看起来不像我的代码：https://kivy.org/docs/api-kivy.uix.tabbedpanel.html

我的代码：

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()
 # join all items in a list into 1 big string

我尝试添加tabpannel但我有两个问题： 1）如何更改标签名称？并删除“defaulttab” 2）为什么我的小部件不在我的标签中？

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()
 # join all items in a list into 1 big string
