Question

我正在尝试使用python为我的公司开发一个小型gui应用程序。有一个包含按钮的主窗口，这些按钮将根据需要启动更多窗口。子窗口之一包含Entry＆Combobox窗口小部件，我希望在提交详细信息或关闭子窗口之前暂停执行。

主窗口代码

class SCInstaller():
    def __init__(self, master):

        #master.geometry("800x450+400+300")
        self.content = ttk.Frame(master)
        self.content.pack()
        ttk.Button(self.content, text="CCR", command = ccr).grid(row = 0, column = 0,padx = 5, pady = 5)
        ttk.Button(self.content, text="Reconciliation of Bank Statement", command = recon).grid(row = 0, column = 2, padx = 5, pady = 5)
        ttk.Button(self.content, text="Customer Take-On", command = cust_takeon).grid(row = 1, column = 0, padx = 5, pady = 5)
        ttk.Button(self.content, text="TBD", command = func4).grid(row = 1, column = 2, padx = 5, pady = 5)
        #messagebox.showinfo(title = "Info", message = "The CCR has been generated")

if __name__ == "__main__":
    root = Tk()
    val = SCInstaller(root)
    root.mainloop()

启动子窗口的代码

def newCI():
    root = Toplevel()
    new_customer = messagebox.askquestion(title = "New Customer", message = "Are there new customers to be added?")
    if new_customer == "yes":
        root.destroy()
        logging.debug("YAY")
        initCustomer() #has code to launch new window
        logging.debug("Here")
        #
        #To develop an UI for entering a new customer - Probably a new function or continue here
    else:
        root.destroy()
        logging.debug("NAY")

子窗口的代码

class ctakenon:
    def __init__(self,root):
         #code for entry and label widgets 
         #with buttons for submit, reset and cancel

    def submit(self):

        messagebox.showinfo(title="Submit", message="The details have been saved")

    def cancel(self, root):
        config.resp = messagebox.askquestion(title="Cancel", message= "Do you want to cancel")
        if config.resp  == "yes":
            root.withdraw()
            return
        else:
            pass

    def on_closing(self, root):
        config.resp = messagebox.askquestion("Quit", "Do you want to quit?")
        if config.resp  == "yes":
            root.withdraw()
            print("123")


def initCustomer():
    logging.debug("Inside Customer Take On")
    logging.debug(config.resp)
    root = Toplevel()
    ctakeon(root)

请原谅最后一部分中的巨大代码。它主要包括标签和条目。单击子窗口中的提交按钮时，该信息将附加到全局变量，并且在取消时该窗口关闭。使用函数initCustomer（）并立即执行该行，甚至在子窗口启动之前。

是否有一种方法可以暂停执行，直到添加了子窗口中的信息，即直到子窗口关闭为止。

有没有办法在子窗口关闭之前停止python代码执行？
