Question

我正在使用这段代码制作一个文本编辑器，我正在尝试添加菜单和快捷方式，我将在以后植入，现在我不知道该怎么做（这是另一个问题，但如果你知道答案请分享。但无论如何我得到这个错误，我不知道为什么。错误：

    Traceback (most recent call last):
        File "C:\Python27\Completed Projects\editor.py", line 90, in <module>
          Editor().mainloop()
        File "C:\Python27\Completed Projects\editor.py", line 52, in __init__
          filemenu.add_command(text='Save',  command=self.onSave).pack(side=LEFT)
        File "C:\Python27\lib\lib-tk\Tkinter.py", line 2683, in add_command
          self.add('command', cnf or kw)

          self._options(cnf, kw))

Answer 1

只需将text更改为label即可解决您的问题。例如：

filemenu.add_command(text='Save',  command=self.onSave)

应该是

filemenu.add_command(label='Save',  command=self.onSave)

tcl中的tcl错误
