Windwomanager 与 TappedPanels

Question

主要.py：

from kivy.app import App
from kivy.lang import Builder
from kivy.uix.screenmanager import ScreenManager, Screen
from kivy.uix.tabbedpanel import TabbedPanel




class Test(TabbedPanel):
    pass

class MainWindow(Screen):
    pass


class SecondWindow(Screen):
    pass


class WindowManager(ScreenManager):
    pass



kv = Builder.load_file("settings.kv")


class MyMainApp(App):
    def build(self):
        return kv


if __name__ == "__main__":
    MyMainApp().run()

设置.kv：

WindowManager:
    MainWindow:
    SecondWindow:
    Test:


<MainWindow>:
    name: "main"

    GridLayout:
        cols:2


        Button:
            text: "New Order"
            on_release:
                app.root.current = "tabs"
                root.manager.transition.direction = "left"


        Button:
            text: "Basket"
            on_release:
                app.root.current = "second"
                root.manager.transition.direction = "left"


<SecondWindow>:
    name: "second"

    Button:
        text: "Go Back"
        on_release:
            app.root.current = "main"
            root.manager.transition.direction = "right"


<Test>:
    name: "test"
    size_hint: .5, .5
    pos_hint: {'center_x': .5, 'center_y': .5}
    do_default_tab: False

    TabbedPanelItem:
        text: 'first tab'
        Label:
            text: 'First tab content area'
    TabbedPanelItem:
        text: 'tab2'
        BoxLayout:
            Label:
                text: 'Second tab content area'
            Button:
                text: 'Button that does nothing'
    TabbedPanelItem:
        text: 'tab3'
        RstDocument:
            text:
                '\\n'.join(("Hello world", "-----------",
                "You are in the third tab."))

我想要一个从按下按钮开始的过渡，导致选项卡式覆盖，但是屏幕管理器不接受使用 tabbedpanel

 kivy.uix.screenmanager.ScreenManagerException: ScreenManager accepts only Screen widget.

我怎样才能达到这种效果，我是kivy的新手。 我想要一个按钮按下去另一个普通屏幕，而另一个按钮打开一个标签式屏幕，

Answer 1

只需将您的TabbedPanel放在Screen 。

Answer 2

再会。 使用您的屏幕管理器在每个屏幕之间切换。 然后屏幕包含您放置在其中的任何内容的独特布局。 这可能包括带有标签的屏幕。

Answer 3

只需将 TabblePanel 添加到您的屏幕之一。

<BlaBlaScreen>:
    name: 'BlaBla'
    TabbedPanel:
        do_default_tab: False
        TabbedPanelItem:
            text: "something"
