关于tkinter的一个很简单的编辑器代码错误

rubee

#!/usr/local/bin/python from Tkinter import * from ScrolledText import* import tkMessageBox from tkFileDialog import * import fileinput tl = [] root = None def die():     sys.exit(0) def about():     tkMessageBox.showinfo("Tkeditor","test\n" "2007.09.16\n" "author:rubee") class editor:     def __init__(self,rt):         if rt == None:             self.t = Tk()         else:             self.t = Toplevel(rt)         self.t.title("Tkeditor %d" % len(tl))         self.bar = Menu(rt)         self.filem = Menu(self.bar)         self.filem.add_command(label="Open...",command=self.openfile)         self.filem.add_command(label="New...",command=neweditor)         self.filem.add_command(label="Save as...",command=self.savefile)         self.filem.add_command(label="Close",command=self.close)         self.filem.add_separator()         self.filem.add_command(label="Exit",command=die)         self.helpm = Menu(self.bar)         self.helpm.addcommand(label="About",command=About)         self.bar.add_cascade(label="File",menu=self.filem)         self.bar.add_cascade(label="Help",menu=self.helpm)         self.t.config(menu=self.bar)         self.f = Frame (self.t,width=512)         self.f.pack(expand=1,fill=BOTH)         self.st = ScrolledText(self.f,background="white")         self.st.pack(side=LEFT,fill=BOTH,expand=1) def close(self):     self.t.destroy() def openfile(self):     pl = END     oname = askopenfilename(filetypes=(("python files","*.py")))     if oname:         for line in fileinput.input(oname):             self.st.insert(pl,line)         self.t.title(oname) def savefile(self):     sname = asksaveasfilename()     if sname:         ofp = open(sname,"w")         ofp.write(self.st.get(1.0,END))         ofp.flush()         ofp.close()         self.t.title(sname) def neweditor():     global root     tl.append(editor(root)) if __name__== "__main__":     root = None     tl.append (editor(root))     root = tl[0].t root.mainloop()

这段代码错在什么地方了？

缩进问题:(例如)
    self.filem.add_command(label="Open...",command=self.openfile)

但是openfile不在类中.

Menu控件问题:
    self.helpm.addcommand(label="About",command=About)
AttributeError: Menu instance has no attribute 'addcommand'

我改过后，可以运行，但是出现不了我想要的结果

真的可以运行吗？
self.filem.add_command(label="New...",command=neweditor)
但你的neweditor定义是类里面。

类似的缩进问题还有不少。

给你调好了,运行一下,看能得到你要的结果不?

可以了，谢谢 。我好好看看我的错误！
