仅在一侧向tkinter小部件添加填充 [英] Adding padding to a tkinter widget only on one side

问题描述

如何在tkinter窗口小部件居中的情况下向tkinter窗口添加填充? 我试过了:

How can I add padding to a tkinter window, without tkinter centering the widget? I tried:

 self.canvas_l = Label(self.master, text="choose a color:", font="helvetica 12")
 self.canvas_l.grid(row=9, column=1, sticky=S, ipady=30)

和

 self.canvas_l = Label(self.master, text="choose a color:", font="helvetica 12")
 self.canvas_l.grid(row=9, column=1, rowspan=2, sticky=S, pady=30)

我只希望在标签顶部填充30像素.

I want 30px padding only on the top of the label.

推荐答案

grid和pack方法的填充选项padx和pady可以占用 2元组代表左/右和上/下填充.

The padding options padx and pady of the grid and pack methods can take a 2-tuple that represent the left/right and top/bottom padding.

这是一个例子:

import tkinter as tk

class MyApp():
    def __init__(self):
        self.root = tk.Tk()
        l1 = tk.Label(self.root, text="Hello")
        l2 = tk.Label(self.root, text="World")
        l1.grid(row=0, column=0, padx=(100, 10))
        l2.grid(row=1, column=0, padx=(10, 100)) 

app = MyApp()
app.root.mainloop()
