Question

withdraw和wm_withdraw有什么区别？

import time
import tkinter as tk

def hide():
    root.withdraw()
    time.sleep(2)
    root.deiconify()

root = tk.Tk()
tk.Button(root, text = 'hide', command = hide).pack()
root.mainloop()

单击“隐藏”按钮时，窗口被隐藏。它从面板（任务栏）消失，并且在任务视图（所有打开的窗口的同时视图）中2秒钟不可见。

import time
import tkinter as tk

def hide():
    root.wm_withdraw()
    time.sleep(2)
    root.deiconify()

root = tk.Tk()
tk.Button(root, text = 'hide', command = hide).pack()
root.mainloop()

相同的代码，但用wm_withdraw代替withdraw。再次，单击“隐藏”按钮使任务栏条目和窗口本身都不可见2秒钟。

这两个之间有什么区别吗？我应该使用哪一个？此外，我应该使用deiconify还是wm_deiconify？所有四个组合（withdraw，deiconify，wm_withdraw，deiconify，withdraw，wm_deiconify，wm_withdraw，{{1} }）似乎做的完全一样。是否有任何应用程序可以执行不同的操作？

Answer 1

它们之间没有区别-它们（withdraw和deiconify）只是wm_对应对象的简称。

在Wm class下与Window manager进行交互的所有功能也是如此。

Answer 2

withdraw和wm_withdraw之间没有区别。我无法指定执行此操作的原因，但是这是tkinter的来源，我们在其中包含行withdraw = wm_withdraw（这很清楚两个调用都以相同的方法结束）：

def wm_withdraw(self):
    """Withdraw this widget from the screen such that it is unmapped
    and forgotten by the window manager. Re-draw it with wm_deiconify."""
    return self.tk.call('wm', 'withdraw', self._w)
withdraw = wm_withdraw

使用withdraw和wm_withdraw隐藏tkinter窗口
