Question

我不明白如何在Python Tkinter中使用grid（）函数和pack（）。我已经看过一个教程，但我无法对我想要的项目进行排序。我使用的是pack功能，但我不知道网格功能是否更好......我还希望小部件根据屏幕大小灵活调整。该应用程序专为7＆＃34;屏幕（Raspberry pi的tactil屏幕）但也许它可以在另一个屏幕上工作...... 我附上了一个我更喜欢的布局链接，我希望有人可以帮助我！谢谢！！

如果您在小部件上使用grid，则必须先使用pack。举个例子：

from Tkinter import *

root = Tk()
root.title("Test: Pack and Grid")
label = Label(root)
label.pack() # Pack Command: Show my widget 'label' on the screen.
label.grid(row=0, column=0) # Grid Command: I want my widget 'label' to be on the first(0) row and on the first column(0)
