python之Tkinter 常规语句不起作用

所以我一直在研究这个非常简单的聊天程序，但无论我做什么，我似乎都无法让它正常工作。由于某种原因，像“state = DISABLED”和“sticky = N+S+E+W”这样的常规语句不再有效，只会导致以下错误:

Traceback (most recent call last): 
  File "C:\Users\K2\Desktop\Projekt 1\chWin.py", line 60, in <module> 
    chWin = chWin() 
  File "C:\Users\K2\Desktop\Projekt 1\chWin.py", line 12, in __init__ 
    self.chatWin.configure( bg = '#747371', fg = 'orange', state = DISABLED ) 
NameError: global name 'DISABLED' is not defined 

我真的没主意了，到处都找不到答案。也许这真的很简单，不知道!请帮忙! `

import tkinter as GUI 
 
switch = False 
 
class chWin( GUI.Tk ): 
    def __init__( self ): 
        GUI.Tk.__init__( self ) 
 
 
        #Medalandefönster 
        self.chatWin = GUI.Text( self ) 
        self.chatWin.configure( bg = '#747371', fg = 'orange', state = DISABLED ) 
        self.chatWin.grid( row = 0, column = 0, sticky = N+S+E+W) 
 
        #Scrollbaren 
        self.scrl = GUI.Scrollbar(self) 
        self.scrl.grid( row = 0, column = 0, sticky = N+S+E+W) 
 
        #Gör så att scrollbar fungerar 
 
        self.scrl.configure( command = self.chatWin.yview) 
        self.chatWin.configure( yscrollcommand = self.scrl.set, state = DISABLED ) 
 
        #Medalandeinput 
        self.msg = GUI.Entry( self ) 
        self.msg.configure( bg = '#262626', fg = 'orange' ) 
        self.msg.grid( row = 1, sticky = N+S+E+W) 
 
        #Skicka-knapp 
        self.btn = GUI.Button( self, text = '<< Send >>', command = self.sendMsg ) 
        self.btn.configure( bg = 'orange', fg = 'black' ) 
        self.btn.bind('<Button-1>', self.sendMsg) 
        self.btn.grid( row = 1, sticky = N+S+E+W) 
 
        #Binder "Enter" till knappen 
        self.msg.bind('<Return>', self.sendMsg ) 
 
    def sendMsg(self, event=None): 
        global switch 
        send = self.msg.get() 
        print (send) 
        if len(send) < 1: 
            pass 
        else: 
            ext = 'Me:\n  ' 
            ext = ext + send 
            self.chatWin.configure(state = NORMAL) 
            self.chatWin.insert(END, ext + '\n') 
            self.chatWin.yview(END) 
            self.chatWin.configure(state = DISABLED) 
            sak = ext + '\n' 
            switch = True 
            while switch == True: 
                mess = send.encode() 
                s.send(mess) 
                print('client sent: ', mess) 
                switch = False 
            msg.delete(0, END) 
 
chWin = chWin() 
chWin.mainloop()

请您参考如下方法:

你需要 GUI.DISABLED 因为 DISABLED 是 tkinter 命名空间的一部分并且你有:

import tkinter as GUI 

同样适用于N、E、W、S、NORMAL , END -- GUI.N, GUI.E, ...
