如何将文件的内容放入Tkinter文本中？

Question

我打算从tkinter.filedialog.askopenfile打开文件中的py文件的内容Tkinter文本部件。下面的代码：

# -*- coding: utf-8 -*- 

import tkinter.messagebox 
import tkinter as tk 
import tkinter.ttk as ttk 
import tkinter.filedialog 


myfonts = {'times': 'times 18 bold', 'verdana': 'Verdana 10'} 
mypatterns = [('Python', '*.py'), ('Python', '*.pyw')] 


class IdlePlus(tk.Frame): 
    def __init__(self, parent=None): 
     tk.Frame.__init__(self, parent, class_='IdlePlus') 
     self.master = parent 
     self.master.title('IDLE Plus') 
     self.master.geometry('500x500+250+50') 
     self.master.configure(bg='orange') 

     self.master.bind('<Control-q>', self.idleplusQuit) 
     self.master.bind('<Control-o>', self.myfileOpen) 

     self.myBarMenu() 

     self.myNoteBook() 

    def myfileOpen(self): 
     self.myfile = tk.filedialog.askopenfile(filetypes=mypatterns, 
            title='Open a Python file', mode='rb') 
     loadedfile = self.myfile.read() 
     self.myfile.close() 
     print(loadedfile) 

    def myNoteBook(self): 
     self.notebook = ttk.Notebook(self.master, width=500, height=600) 
     self.framenotebook1 = ttk.Frame(self.notebook) 
     self.framenotebook2 = ttk.Frame(self.notebook) 
     self.notebook.add(self.framenotebook1, text='One') 
     self.notebook.add(self.framenotebook2, text='Two') 
     self.notebook.pack(side='top', expand='yes', fill='both') 
     self.scrollbarView = tk.Scrollbar(self.framenotebook1, 
              orient='vertical', takefocus=False, 
              highlightthickness=0) 
     self.textView = tk.Text(self.framenotebook1, bg='blue', fg='white', 
         wrap='word', highlightthickness=0) 
     self.scrollbarView.config(command=self.textView.yview) 
     self.textView.config(yscrollcommand=self.scrollbarView.set) 
     self.scrollbarView.pack(side='right', fill='y') 
     self.textView.pack(side='left', expand='yes', fill='both') 

    def myBarMenu(self): 
     mymenubar = tk.Menu(self.master) 

     filemenu = tk.Menu(mymenubar, tearoff=0) 
     filemenu.add_command(label='New File', underline=0, 
          accelerator='CTRL+N') 
     filemenu.add_command(label='Open File', underline=0, 
          accelerator='CTRL+O', command=self.myfileOpen) 
     filemenu.add_separator() 
     filemenu.add_command(label='Save File', underline=0, 
          accelerator='CTRL+S') 
     filemenu.add_command(label='Save As...', accelerator='CTRL+SHIFT+S') 
     filemenu.add_command(label='Close File', underline=0, 
          accelerator='ALT+F4') 
     filemenu.add_separator() 
     filemenu.add_command(label='Print File', underline=0, 
          accelerator='CTRL+P') 
     filemenu.add_separator() 
     filemenu.add_command(label='Exit', underline=0, 
          accelerator='CTRL+Q', command=self.idleplusQuit) 
     mymenubar.add_cascade(label='File', underline=0, menu=filemenu) 

     aboutmenu = tk.Menu(mymenubar, tearoff=0) 
     aboutmenu.add_command(label='Help', underline=0, accelerator='F1') 
     aboutmenu.add_command(label='About IDLE-Plus', underline=0) 
     mymenubar.add_cascade(label='Help', underline=0, menu=aboutmenu) 

     self.master.configure(menu=mymenubar) 

    def idleplusQuit(self, event=None): 
     if tk.messagebox.askokcancel('Quit', 'Do you really want to exit?', 
            parent=self.master): 
      self.master.destroy() 


window = tk.Tk() 
myapp = IdlePlus(window) 
window.mainloop() 

我希望把内容loadedfile在self.textView，实际内容将显示在终端打印的罚款。 感谢

你可以这样做：

def myfileOpen(self): 
    self.myfile = tk.filedialog.askopenfile(filetypes=mypatterns, 
           title='Open a Python file', mode='r') 
    loadedfile = self.myfile.read() 
    self.myfile.close() 
    self.textView.insert("end", loadedfile)
