我对python很陌生。

我编码如下。当用户单击“单击按钮设置 CPE”时。按钮，将出现对话窗口并显示客户列表。

我的问题是当用户单击“单击按钮以设置 CPE”时。按钮，该Listing()功能首先起作用。那时主窗口已经死了。完成后Listing()，出现对话框。

我该怎么做才能使对话框首先出现并在对话框出现后显示信息。

import Tkinter

class myWindow:
    addr = ''
    def __init__(self):

        self.mw = Tkinter.Tk()
        self.mw.option_add("*font", ("Arial", 15, "normal"))
        self.mw.geometry("+250+200")
        self.mw.title("Example of Custom Dialog-Window")

        # CPE
        self.btn_cpe = Tkinter.Button(self.mw, text = "Click button to setup CPE.", command = self.btnCPE)
        self.btn_cpe.pack(padx = 20, pady = 20)
        self.mw.mainloop()


    def btnCPE(self):

        self.dialogwindow = Tkinter.Toplevel()
        self.dialogwindow.title("Dialog Window")
        self.dialogwindow.geometry("+500+350")
        self.dialogwindow.maxsize(500, 350)
        self.dialogwindow.minsize(500, 350)

        self.lab1 = Tkinter.Label(self.dialogwindow, text = "Checking info")
        self.lab1.pack()

        self.lab_addr = Tkinter.Label(self.dialogwindow, text = "Address : ")
        self.lab_addr.pack()

        # Refresh
        self.btn_refresh = Tkinter.Button(self.dialogwindow, text = "Refresh", command = self.refresh)
        self.btn_refresh.pack()

        self.btn_cpe_exit = Tkinter.Button(self.dialogwindow, text = "Exit", command = self.dialogwindow.destroy )
        self.btn_cpe_exit.pack()

        # This is the important line: It tells the main-window to lock:
        self.dialogwindow.grab_set() 

        self.Listing()
        self.lab_addr['text'] = "address : " + self.addr;

    def Listing(self):
        # access the db and set the address into self.addr

尝试这个：

import Tkinter

class myWindow:
    addr = ''
    def __init__(self):
        # CPE
        self.btn_cpe = Tkinter.Button(mw, text = "Click button to setup CPE.", command = self.btnCPE)
        self.btn_cpe.pack(padx = 20, pady = 20)

    def btnCPE(self):

        self.dialogwindow = Tkinter.Toplevel()
        self.dialogwindow.title("Dialog Window")
        self.dialogwindow.geometry("+500+350")
        self.dialogwindow.maxsize(500, 350)
        self.dialogwindow.minsize(500, 350)

        self.lab1 = Tkinter.Label(self.dialogwindow, text = "Checking info")
        self.lab1.pack()

        self.lab_addr = Tkinter.Label(self.dialogwindow, text = "Address : ")
        self.lab_addr.pack()

        # Refresh
        self.btn_refresh = Tkinter.Button(self.dialogwindow, text = "Refresh", command = self.refresh)
        self.btn_refresh.pack()

        self.btn_cpe_exit = Tkinter.Button(self.dialogwindow, text = "Exit", command = self.dialogwindow.destroy )
        self.btn_cpe_exit.pack()

        # This is the important line: It tells the main-window to lock:
        self.dialogwindow.grab_set() 

        self.Listing()
        self.lab_addr['text'] = "address : " + self.addr;

    def Listing(self):
        print "hola"
        # access the db and set the address into self.addr

mw = Tkinter.Tk()
app=myWindow()
mw.option_add("*font", ("Arial", 15, "normal"))
mw.geometry("+250+200")
mw.title("Example of Custom Dialog-Window")
mw.mainloop()

另外，尽量不要在构造函数中包含 UI 部分。告诉我是否有帮助
