如何將光標懸停在標籤上時將其改變爲手形？

Question

from tkinter import * 
root = Tk() 
def changeCursor(event, pointerName): 
    root.cursor(pointerName) 
link = Label(root, text="Link") 
link.bind("<Motion>", lambda event : changeCursor(event, "hand")) 
link.pack() 
root.mainloop() 

我希望當光標懸停在它上面時，我的光標變成了「手」。當光標離開標籤佔用的區域時，我也想將光標改回箭頭。不過，我得到以下錯誤：

Exception in Tkinter callback 
Traceback (most recent call last): 
    File "C:\Users\Arnob\AppData\Local\Programs\Python\Python36- 
32\lib\idlelib\run.py", line 137, in main 
    seq, request = rpc.request_queue.get(block=True, timeout=0.05) 
    File "C:\Users\Arnob\AppData\Local\Programs\Python\Python36- 
32\lib\queue.py", line 172, in get 
    raise Empty 
queue.Empty 

During handling of the above exception, another exception occurred: 

Traceback (most recent call last): 
    File "C:\Users\Arnob\AppData\Local\Programs\Python\Python36- 
32\lib\tkinter\__init__.py", line 1699, in __call__ 
    return self.func(*args) 
    File "<pyshell#7>", line 1, in <lambda> 
    File "<pyshell#4>", line 2, in changePointer 
    File "C:\Users\Arnob\AppData\Local\Programs\Python\Python36-

    return getattr(self.tk, attr) 
AttributeError: '_tkinter.tkapp' object has no attribute 'cursor' 

如何改變光標變爲手形時，它是由Label佔領，然後改回爲箭頭的區域，當它離開由標籤所佔用的面積？

Answer 1

如果你想光標總是手，只是配置標籤有一個光標：

import tkinter as tk 

root = tk.Tk() 

label = tk.Label(root, text="Hello, world", background="bisque", cursor="hand1") 
label.pack(side="top", fill="x", padx=10, pady=10) 

root.mainloop()
