Kivy 减小GridLayout中列的宽度

我有以下代码：

import kivy
from kivy.app import App
from kivy.uix.gridlayout import GridLayout
from kivy.uix.image import Image
from kivy.uix.label import Label
from kivy.uix.button import Button

class TedeGrid(GridLayout):
    def __init__(self, **kwargs):
        super(TedeGrid, self).__init__(**kwargs)
        self.cols = 3
        self.img = Image(source='sriyantra.png')
        self.add_widget(self.img)
        self.add_widget(Label(text="HELLO"))

        self.inside = GridLayout()
        self.inside.cols = 1

        self.add_widget(self.inside)

        self.next_button = Button(text="Next")
        self.inside.add_widget(self.next_button)

        self.prev_button = Button(text="Prev")
        self.inside.add_widget(self.prev_button)

class Tedegraph(App):
    def build(self):
        return TedeGrid()

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

我想减少第三列的宽度，例如，第一列宽度的10%

更好的是，如果没有按钮，右边是一个小的点击区域（对

next

事件做出反应），左边是一个小的点击区域（对

prev

事件做出反应）

我会使用一个大的网格布局，我将放置较小的网格布局，并使用

size\u hint=（宽度、高度）

如果您想要一个代码示例，请在代码中添加您使用的照片，以便我可以正确运行它吗？

检查此项，我重新设计了您的代码，希望它有意义。这就是你想要的吗？如果你不明白如何改变某事，告诉我，我会为你改变/解释它

from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.image import Image
from kivy.uix.label import Label
from kivy.config import Config
from kivy.uix.button import Button

class Tedegraph(App):
    def build(self): # I will add everything here
        # For your example, it's better to use boxlayout, you don't want a table/grid like pattern, right?
        mainbox = BoxLayout(orientation="horizontal", # Create the main box layout and make it horizontal
                            spacing=15, # Add spacing between widgets
                            padding=5) # And padding on the sides
        mainbox.add_widget(Button(text="Prev", # Add the prev button
                                  font_size="17dp", # set font size
                                  size_hint=(.3, .2), # make the button smaller
                                  pos_hint={"center_x":0.5, # Center it on the x
                                            "center_y":0.5}, # And on the y
                                  on_press=self.prevscreen)) # Attach a button function
        mainbox.add_widget(Image(source='sriyantra.png')) # Add your image after the button
        mainbox.add_widget(Label(text="HELLO")) # And add the text
        mainbox.add_widget(Button(text="Next", # Add the next button and set the same parameters for the next button
                                  font_size="17dp",
                                  size_hint=(.3, .2),

                                  on_press=self.nextscreen)) # And change the button press function
        return mainbox


     # I created the functions for you
    def nextscreen(self, *args):
        print("Clicked Next")
        # Here you can write the code that you want to do when the prev button is pressed

    def prevscreen(self, *args):
        print("Clicked Prev")
        # Here you can write the code that you want to do when the next button is pressed

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

谢谢，这是照片。请问，您如何在屏幕底部放置一个小部件（组合框）？我不希望它占据右边的空间，这是默认位置，我想把它绑定到底部。谢谢。@xraf您可以使用垂直框布局而不是水平框布局，在这种情况下：mainbox=BoxLayout（orientation=“horizontal”，space=15，padding=5）
