绑定问题

Question

我将一些键绑定到我的save_file函数，它首先保存，然后给出错误代码“AttributeError：'Event'对象没有属性'get'”。当我点击主菜单中的按钮时，我真的不懂cos，它可以工作。知道我应该做什么吗？

    self.text = Text(root, bg="white",  wrap='word', undo=True, foreground="black", exportselection="no")
    self.text.bind("<Control-Alt-s>", self.save_file_as)
    self.text.bind("<Control-s>", self.save_file)
    self.text.bind("<Control-o>", self.open_file)
    self.text.focus_set()
    self.text.pack(fill='both', expand=1)

功能  self.filename =''         self._filetypes = [（'Text'，' .txt'），（'所有文件'，''），]

    #calls the save function
def saveFile(self):
    self.save_file(self.text)

#saving all The files
    def save_file(self, texts):
        self.text2 = texts
        if (self.filename == ''):
            self.save_file_as()
        else:
            f = open(self.filename, 'w')
            f.write(self.text2.get('1.0', 'end'))  # change every 'self' that refers to the Text, to self.text2
            f.close()
            tkinter.messagebox.showinfo('FYI', 'File Saved.')
        root.title(self.filename)
    def save_file_as(self, whatever=None):
        self.filename = tkinter.filedialog.asksaveasfilename(defaultextension='.txt', filetypes=self._filetypes)
        f = open(self.filename, 'w')
        f.write(self.text2.get('1.0', 'end'))
        f.close()
        tkinter.messagebox.showinfo('FYI', 'File Saved')

调用绑定函数时，会将事件对象传递给它。你认为你的参数text实际上就是那个事件。试试这个：

    def save_file(self, event):
        self.text2 = event.widget
        if (self.filename == ''):
            self.save_file_as()
        else:
            f = open(self.filename, 'w')
            f.write(self.text2.get('1.0', 'end'))  # change every 'self' that refers to the Text, to self.text2
            f.close()
            tkinter.messagebox.showinfo('FYI', 'File Saved.')
        root.title(self.filename)

    def save_file_as(self, event=None, whatever=None):
        self.filename = tkinter.filedialog.asksaveasfilename(defaultextension='.txt', filetypes=self._filetypes)
        f = open(self.filename, 'w')
        f.write(self.text2.get('1.0', 'end'))
        f.close()
        tkinter.messagebox.showinfo('FYI', 'File Saved')
