我是 Python 开发的新手,从 this 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而不是窗口提供的关闭按钮来调整此应用程序。
# 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)
我添加了按钮并添加了名为 closeConnection 的函数。我使用了所有可能的方法,UI 卡住了,但窗口没有关闭。
def closeConnection(self):
quit()
self.Window.quit()
self.Window.destroy()
我试图弄清楚但无法理解我遗漏了什么。是由于线程还是由于窗口去图标化的东西,或者我不了解窗口层次结构。
提前致谢。

我认为您必须使用此命令才能关闭窗口:export PATH=$PATH:/usr/local/bundle/bin
export BUNDLE_APP_CONFIG=/usr/local/bundle
export GEM_HOME=/usr/local/bundle
