如何记住Python3中tkinter窗口的位置？

我有一个tkinter gui，我希望它在重新启动时保持原来的窗口位置和大小

以下是一个说明如何设置特定位置和尺寸的答案，但不是关于记住设置的单词：

非常感谢您的帮助。

在会话之间记住设置的唯一方法是将它们写入文件。因此，获取根窗口几何体（它是一个字符串）并将其写入文件。如果希望函数作为挂钩自动执行，请将其绑定到“”事件：

def保存大小（事件）：
以open（“myapp.conf”、“w”）作为conf:
conf.write（root.geometry（））#假设root是根窗口
root.bind（“，保存大小）

---

稍后，您可以从文件中读取几何体并将其还原。

我花了相当多的时间才了解这一点的实际实现。所以我想分享我最后的代码。基于DyZ的建议

我没有按建议使用

事件，因为只有在退出前保存才足够

class Window(tk.Tk):

    def __init__(self, *args, **kwargs):
        tk.Tk.__init__(self, *args, **kwargs)

        # ...
        # bla bla bla
        # My GUI codes came here
        # ...

        # Try to load last saved window data
        self.statusbar['text']="reading ini file..."
        ini_file_path = "mapedit.ini"
        try:
            # if the file is there
            # get geometry from file 
            ini_file = open(ini_file_path,'r')
            self.geometry(ini_file.read())
            self.statusbar['text']= "ini file read"
            ini_file.close()
        except:
            # if the file is not there, create the file and use default
            # then use default geometry.
            self.statusbar['text']="ini file not found. New file created."
            ini_file = open(ini_file_path, 'w')
            ini_file.close()
            self.geometry("640x400+100+200")

    def client_exit(self):
        self.save_geo()
        self.destroy()

    def save_geo(self):
        # save current geometry to the ini file 
        try:
            with open("mapedit.ini", 'w') as ini_file:
                ini_file.write(self.geometry())
                self.statusbar['text']="geo sv"
                ini_file.close()
        except:
            statusbar['text']="ini file not found"

'''
   This is where I created GUI instance
'''
if __name__ == "__main__":
    win = Window()
    # attach deletion handler to 'client_exit' method
    win.protocol("WM_DELETE_WINDOW", win.client_exit)
    win.mainloop()

听起来不错，但如何将其与on_resize事件挂钩？我是python新手。您从未问过调整大小事件，这就是为什么我没有回答。检查更新的答案。太好了，我已经把它添加到我的gui类中。这完美地回答了我的问题。但是，我想提出一个小建议：在退出应用程序时更新几何体。这是您唯一真正需要将其写入磁盘的时间。

class Window(tk.Tk):

    def __init__(self, *args, **kwargs):
        tk.Tk.__init__(self, *args, **kwargs)

        # My GUI codes came here
        # ...

        # Try to load last saved window data
        self.statusbar['text']="reading ini file..."
        ini_file_path = "mapedit.ini"
        try:
            # if the file is there
            # get geometry from file 
            ini_file = open(ini_file_path,'r')
            self.geometry(ini_file.read())
            self.statusbar['text']= "ini file read"
            ini_file.close()
        except:
            # if the file is not there, create the file and use default
            # then use default geometry.
            self.statusbar['text']="ini file not found. New file created."
            ini_file = open(ini_file_path, 'w')
            ini_file.close()
            self.geometry("640x400+100+200")

        self.save_geo()
        self.destroy()

                ini_file.write(self.geometry())
                self.statusbar['text']="geo sv"
