在python tkinter中销毁GUI窗口

Question

我是python开发的新手，从这个链接开始学习多客户端，服务器开发。我想通过添加一个关闭按钮来调整这个应用程序，而不是由window提供的关闭按钮。

# GUI class for the chat 
class GUI:
# constructor method
def __init__(self):
# chat window which is currently hidden
self.Window = Tk()
self.Window.withdraw()
# login window
self.login = Toplevel()
# set the title
self.login.title("Login")
self.login.resizable(width=False,
height=False)
self.login.configure(width=400,
height=300)
# create a Label
self.pls = Label(self.login,
text="Please login to continue",
justify=CENTER,
font="Helvetica 14 bold")
self.pls.place(relheight=0.15,
relx=0.2,
rely=0.07)
# create a Label
self.labelName = Label(self.login,
text="Name: ",
font="Helvetica 12")
self.labelName.place(relheight=0.2,
relx=0.1,
rely=0.2)
# create a entry box for
# tyoing the message
self.entryName = Entry(self.login,
font="Helvetica 14")
self.entryName.place(relwidth=0.4,
relheight=0.12,
relx=0.35,
rely=0.2)
# set the focus of the curser
self.entryName.focus()
self.name = self.entryName.get()
# create a Continue Button
# along with action
self.go = Button(self.login,
text="CONTINUE",
font="Helvetica 14 bold",
command=lambda: self.goAhead(self.entryName.get()))
self.go.place(relx=0.4,
rely=0.55)
self.Window.mainloop()
def goAhead(self, name):
self.login.destroy()
self.layout("Client chat")

# The main layout of the chat
def layout(self, name):
self.name = name
# to show chat window
self.Window.deiconify()
self.Window.title(self.name)
self.Window.resizable(width=False,
height=False)
self.Window.configure(width=470,
height=550,
bg="#17202A")
self.labelHead = Label(self.Window,
bg="#17202A",
fg="#EAECEE",
text=self.name,
font="Helvetica 13 bold",
pady=5)
self.labelHead.place(relwidth=1)
self.line = Label(self.Window,
width=450,
bg="#ABB2B9")
self.line.place(relwidth=1,
rely=0.07,
relheight=0.012)
self.textCons = Text(self.Window,
width=20,
height=2,
bg="#17202A",
fg="#EAECEE",
font="Helvetica 14",
padx=5,
pady=5)
self.textCons.place(relheight=0.745,
relwidth=1,
rely=0.08)
self.labelBottom = Label(self.Window,
bg="#ABB2B9",
height=80)
self.labelBottom.place(relwidth=1,
rely=0.825)
# create a Send Button
self.buttonMsg = Button(self.labelBottom,
text="Close",
font="Helvetica 10 bold",
width=20,
bg="#ABB2B9",
command=lambda: self.closeConnection())
self.buttonMsg.place(relx=0.50,
rely=0.008,
relheight=0.06,
relwidth=0.22)
self.selectbuttonMsg = Button(self.labelBottom,
text="Select",
font="Helvetica 10 bold",
width=20,
bg="#ABB2B9",
command=lambda: self.readFile())
self.selectbuttonMsg.place(relx=0.25,
rely=0.008,
relheight=0.06,
relwidth=0.22)
self.textCons.config(cursor="arrow")
# create a scroll bar
scrollbar = Scrollbar(self.textCons)
# place the scroll bar
# into the gui window
scrollbar.place(relheight=1,
relx=0.974)
scrollbar.config(command=self.textCons.yview)
self.textCons.config(state=DISABLED)

我添加了按钮和添加了名为closeConnection的功能。我用了所有可能的东西，UI卡住了，但窗口没有关闭。

def closeConnection(self):
quit()
self.Window.quit()
self.Window.destroy()

我试图弄清楚，但未能理解我失踪的地方。是由于线程还是由于窗口去图标化的东西，或者我不理解窗口的层次结构。

提前感谢。

我认为你必须使用这个命令来关闭窗口:self.root.destroy()
