我无法将我的一个文本文件加载到GUI中。我有一个加载函数(在菜单栏上),并创建了一个列表框。

加载菜单和列表框的代码:

class View(Listbox):
    def __init__(self, master):
        Listbox.__init__(self, master)      #makes view class listbox


class Controller(object):
    def __init__(self, master):
        """ Main interface:
        master - the top level window

        """
        self._master = master
        menubar = Menu(self._master)

        frame1 = Frame(self._master)
        frame1.pack(side=TOP, fill=BOTH, padx=5,expand=True)

        self._Listbox=View(frame1)
        self._Listbox.pack(side = TOP,fill=BOTH, expand = True,pady=20)

        menubar = Menu(self._master)
        filemenu = Menu(menubar, tearoff=0)
        filemenu.add_command(label="Open rooms file", command = self.file_open)


    def file_open(self):
        filename = tkFileDialog.askopenfilename() 

加载文件有效,但当前加载的文本文档在哪里?如何在列表框中显示它?

这有效:

from Tkinter import *
import tkFileDialog

class View(Listbox):
    def __init__(self, master):
        Listbox.__init__(self, master)      #makes view class listbox


class Controller(object):
    def __init__(self, master):
        """ Main interface:
        master - the top level window
        """
        self._master = master

        frame1 = Frame(self._master)
        frame1.pack(side=TOP, fill=BOTH, padx=5,expand=True)

        self._Listbox=View(frame1)
        self._Listbox.pack(side = TOP,fill=BOTH, expand = True,pady=20)

        menubar = Menu(self._master)
        filemenu = Menu(menubar, tearoff=0)
        filemenu.add_command(label="Open", command = self.file_open)
        menubar.add_cascade(label='File',menu=filemenu)
        self._master.config(menu=menubar)

    def file_open(self):
        filename = tkFileDialog.askopenfilename()

        #insert each line in the file into the listbox
        with open(filename,'r') as f:
            for line in f:
                self._Listbox.insert(END,line)



if __name__ == "__main__":
    root=Tk()
    c=Controller(root)
    root.mainloop()

这只与你的代码略有不同......首先,我删除了第一个menubar = Menu(self._master),因为它没有真正做任何事情。其次,我添加了“级联”menubar.add_cascade(label='File',menu=filemenu),第三,我实际将菜单附加到根Tk窗口:self._master.config(menu=menubar)
