如何在 python 中使用 kivy 在 TabeedPanel 中使用 GridLayout

Question

我正在尝试使用 kivy 和 TabeedPanel 在 python 中制作 GUI。放置标签、TextInput、按钮的确切位置会出现一些问题。我无法同时放置多个标签 TextInput。这就是我在代码中评论的原因。我也尝试了 GridLayout，但无法准确排列。你能帮助我吗？提前致谢。

from kivy.app import App
from kivy.uix.tabbedpanel import TabbedPanel, TabbedPanelItem
from kivy.lang import Builder
from kivy.uix.checkbox import CheckBox
from kivy.uix.button import Button
from kivy.app import App
from kivy.uix.textinput import TextInput
import json

Builder.load_string("""

<Test>:
    do_default_tab: False

    TabbedPanelItem:
        text: 'page1'
        BoxLayout:
            Label:
                text: 'label'
            TextInput:
                text: 'TextInput'
            CheckBox: 
                text: 'CheckBox'
            Button:
                text: 'save'

    #BoxLayout:
     #   orientation: 'vertical'
      #  BoxLayout:
       #     orientation: 'horizontal'
        #    Label:
         #       text: 'label'



    TabbedPanelItem:
        text: 'page2'
        BoxLayout:
            Label:
                text: 'number1'
        #TextInput:
        #   text: 'TextInput'
            Label:
                text: 'number2'
       # TextInput:
       #    text: 'TextInput'
            Button:
                text: 'button'

""")

class Test(TabbedPanel):
    pass

class MyApp(App):

    def build(self):
        test = Test()
        return test


if __name__ == '__main__':
    MyApp().run()

按照您的示例，您可以使用 BoxLayouts，但需要正确嵌套它们：

from kivy.app import App
from kivy.uix.tabbedpanel import TabbedPanel
from kivy.lang import Builder

Builder.load_string("""

<Test>:
    do_default_tab: False

    TabbedPanelItem:
        text: 'page1'

        BoxLayout:
            padding: 50, 50, 50, 50
            orientation: 'horizontal'

            BoxLayout:
                spacing: 50
                orientation: 'vertical'
                size_hint_x: 1
                Label:
                    text: 'label'
                Label:
                    text: 'label'
                Label:
                    text: 'label'

            BoxLayout:
                spacing: 50
                orientation: 'vertical'
                TextInput:
                    text: 'TextInput'
                TextInput:
                    text: 'TextInput'
                TextInput:
                    text: 'TextInput'

            BoxLayout:
                spacing: 50
                orientation: 'vertical'
                size_hint_x: 0.40
                CheckBox: 
                    text: 'CheckBox'
                CheckBox:

            BoxLayout:

                size_hint_x: 0.60
                Button:
                    text: 'save'
                Button:
                    text: 'save'
                Button:

这是一个使用 GridLayout 的例子，我在你的其他问题中提到过。仅供参考，您可以通过多种方式解决此问题。我个人喜欢将 gridlayout 与表单一起使用，因为如果需要的话，它很容易放置 ScrollViews。

阅读 kv 语言 here 以帮助保持内容干燥和其他内容。如果一个 widget 是在 kv 中定义的，那么你不需要在你的文件的顶部导入它们。

示例：

from kivy.app import App
from kivy.uix.tabbedpanel import TabbedPanel
from kivy.lang import Builder

Builder.load_string("""
<MyLabel@Label>:
    size_hint: (None, None)
    size: (400, 100)

<MyTextInput@TextInput>:
    size_hint: (None, None)
    size: (600, 100)

<MyButton@Button>:
    size_hint: (None, None)
    size: (400, 100)

<MyCheckBox@AnchorLayout>:
    # I'm nesting the checkbox here b/c it is hard to see if the background is not lightened.
    size_hint: (None, None)
    size: (100, 100)
    anchor_x: "center"
    anchor_y: "center"
    canvas.before:
        Color:
            rgba: [0.7, 0.7, 0.7, 1]
        Rectangle:
            pos: self.pos
            size: self.size
    CheckBox:

<Test>:
    do_default_tab: False

    TabbedPanelItem:
        text: 'page1'
        GridLayout:
            rows: 3
            cols: 4
            padding: [10, 100]
            spacing: [10, 50]
            MyLabel:
                text: "Label 1"
            MyTextInput:
            MyCheckBox:
            MyButton:
                text: "Button 1"
            MyLabel:
                text: "Label 3"
            MyTextInput:
            MyCheckBox:
            MyButton:
                text: "Button 2"
            MyLabel:

            MyTextInput:
            MyCheckBox:
            MyButton:

    TabbedPanelItem:

        GridLayout:
            rows: 3
            cols: 2

            spacing: [10, 50]
            MyLabel:
