在 Tkinter 中运行关于窗口最小化的命令 [英] Running a command on Window minimization in Tkinter

问题描述

每当按下最小化按钮时，我都有一个 Tkinter 窗口我想运行一个命令，我该怎么做?

I have a Tkinter window whenever the minimize button is pressed I'd like to run a command, how do I do this?

我知道 w.protocol("WM_DELETE_WINDOW", w.command) 将在退出时运行命令.

I know w.protocol("WM_DELETE_WINDOW", w.command) will run a command on exit.

推荐答案

您可以绑定到 事件.

You can bind to the <Unmap> event.

例如，运行以下代码，然后最小化主窗口.当主窗口最小化时，工具窗口应该会消失.

For example, run the following code and then minimize the main window. The tool window should disappear when the main window is minimized.

import Tkinter as tk

class App:
    def __init__(self):
        self.root = tk.Tk()
        tk.Label(self.root, text="main window").pack()
        self.t = tk.Toplevel()
        tk.Label(self.t, text="tool window").pack()
        self.root.bind("<Unmap>", self.OnUnmap)
        self.root.bind("<Map>", self.OnMap)
        self.root.mainloop()

    def OnMap(self, event):
        # show the tool window
        self.t.wm_deiconify()

    def OnUnmap(self, event):
        # withdraw the tool window
        self.t.wm_withdraw()

if __name__ == "__main__":
    app=App()
