我试图创建一个名为Menu的类，它将创建一个右键单击菜单，无论哪个窗口小部件给它。在这种情况下，self.Label。了解Python类，试图使自定义窗口小部件
然而，当我运行我的程序，我得到以下错误：
Traceback (most recent call last):

AttributeError: B3Menu instance has no attribute 'tk'
我的计划：
import Tkinter
class B3Menu:
def __init__ (self, wid):
self.wid = wid
self.MeVar = Tkinter.StringVar()
self.Me = Tkinter.Menu(self, tearoff=0,
activebackground='grey15',
activeforeground='grey95')
self.Me.add_radiobutton(label='Cut', variable=self.MeVar,
command=self.menu_beh,
accelerator='Ctrl-x')
self.Me.add_radiobutton(label='Copy', variable=self.MeVar,
command=self.menu_beh,
accelerator='Ctrl-c')
self.Me.add_separator()
self.Me.add_radiobutton(label='Paste', variable=self.MeVar,
command=self.menu_beh,
accelerator='Ctrl-v')
self.wid.bind("<ButtonRelease-3>", self.menu_pos)
def menu_pos (self, event=None):
self.Me.post(event.x_root, event.y_root)
def menu_beh (self):
''' Handles the behavior of right click menu '''
if self.MeVar.get() =='Cut':
self.wid.event_generate("<<Cut>>")
if self.MeVar.get() =='Copy':
self.wid.event_generate("<<Copy>>")
if self.MeVar.get() =='Paste':
self.wid.event_generate("<<Paste>>")
class Suite(Tkinter.Tk):
def __init__(self):
Tkinter.Tk.__init__(self)
self.Label = Tkinter.Label(self, text='hello')
self.Label.pack()
B3Menu(self.Label)
def run():
Suite().mainloop()
if __name__ == '__main__':
run()
这是我在创建使用蟒蛇类系统部件的第一次尝试。所以我确定我做了很多错误的事情。任何帮助将非常感激。
