我是一名 Python 初學者，正在嘗試通過 Tkinter 學習我的方法，我需要您的幫助。
假設我創建了一個像這樣的簡單按鈕：
import tkinter as tk
window = tk.Tk()
button = tk.Button(text="Hello World!")
button.pack()
window.mainloop()
有沒有辦法可以隱藏然后再次顯示文本？鑒于我可以再創建兩個按鈕來完成隱藏和顯示的作業。我曾嘗試使用 button.pack_forget()，但它會隱藏整個按鈕。任何幫助，將不勝感激。

為了使它看起來像按鈕文本消失，您可以通過cget方法使文本顏色與背景顏色相同。
import tkinter as tk
def hide_text():
color = button['bg']
button.config(foreground=color, activeforeground=color)
window = tk.Tk()
button = tk.Button(text="Hello World!",command=hide_text)
button.pack()
window.mainloop()
方法 2 ttk.Button：
import tkinter as tk
from tkinter import ttk
def hide_text():
button.config(text='')
window = tk.Tk()
button = ttk.Button(text="Hello World!",width=100,command=hide_text)
button.pack()
window.mainloop()
使用風格的方法3 ：
import tkinter as tk
from tkinter import ttk
def change_button_style(event):
widget = event.widget
if widget['style'] == 'TButton':
widget.configure(style='VanishedText.TButton')
else:
event.widget.config(style='TButton')
BACKGROUND = '#f0f0f0'
FOREGROUND = '#000000'
window = tk.Tk()
window.configure(bg=BACKGROUND)
style = ttk.Style()
style.theme_use('default')
button = ttk.Button(text="Hello World!",style='VanishedText.TButton')
button.bind('<ButtonPress-1>',change_button_style)#,command=change_button_style
button.pack()
style.map('VanishedText.TButton',
foreground =[('disabled',BACKGROUND),
('!disabled',BACKGROUND),
('pressed',BACKGROUND),
('!pressed',BACKGROUND),
('active',BACKGROUND),
('!active',BACKGROUND)],
background =[('disabled',BACKGROUND),
('!disabled',BACKGROUND),
('pressed',BACKGROUND),
('!pressed',BACKGROUND),
('active',BACKGROUND),
('!active',BACKGROUND)],
focuscolor=[('disabled',BACKGROUND),
('!disabled',BACKGROUND),
('pressed',BACKGROUND),
('!pressed',BACKGROUND),
('active',BACKGROUND),
('!active',BACKGROUND)])
window.mainloop()

您可以簡單地配置和設定文本：
import tkinter as tk
from tkinter import ttk
win=tk.Tk()
def hidetext():
button.config(text="")
button=ttk.Button(win,text="FooBar",command=hidetext)
button.pack()
win.mainloop()
