如何恢复隐藏窗口的功能？

772

应用方法后withdraw，deiconify窗口冻结：它不响应命令，按钮，菜单等不起作用。

那么，真正的问题是该怎么做？

这是项目本身，它有一个“project.py”文件，您至少需要 1 个工作 COM 端口

来自 project.py 文件的代码

resx_win = str(int((GetSystemMetrics(0)/2)-(900/2)))

问题是这样的：

LED_window = Toplevel()
LED_window.grab_set()  # <--

...

def undo():
    win.deiconify()
    LED_window.withdraw()

该方法.grab_set()使子窗口模态化，因此当它存在时，主窗口被阻塞。如果子窗口只是简单地隐藏，那么主窗口将保持阻塞状态。

您需要.grab_set()使用以下方法取消操作.grab_release()：

def undo():
    win.deiconify()
    LED_window.grab_release()
    LED_window.withdraw()

或者不是隐藏，而是销毁子窗口（特别是当你重新进入函数时，LED_window_def旧的子窗口没有返回，而是创建了一个新的，所以隐藏没有意义）：

def undo():
    win.deiconify()
    LED_window.destroy()

第三种选择是不这样做.grab_set()，因为。无论如何，您之前的窗口都是隐藏的，因此阻止它们是没有意义的。您还可以结合最后两个选项：退出时不阻塞和销毁。

withdraw() 从屏幕上删除窗口（不破坏它）。要重绘窗口，请使用 deiconify。当窗口被移除时，状态方法返回“withdrawn”。

from tkinter import *
r = Tk()
r.withdraw()
r.deiconify()

r.mainloop()
