python的tkinter模块中，菜单也可以由你自定义你的风格

下面是我做的demo

运行效果：

 # some miscellaneous callbacks

     global number
     number += 1

     tk.geometry('300x300')
     tk.title('Demo %s'%number)

     print("opening OLD file")

 def print_something():
     print("picked a menu item")

 def makeCommandMenu():
     # make menu button
     Command_button = Menubutton(mBar, text='Simple Button Commands',
                                 underline=0)
     Command_button.pack(side=LEFT, padx="2m")

     # make the pulldown part of the File menu. The parameter passed is the master.
     # we attach it to the button as a python attribute called "menu" by convention.
     # hopefully this isn't too confusing...
     Command_button.menu = Menu(Command_button)

     # just to be cute, let's disable the undo option:
     Command_button.menu.add_command(label="Undo")
     # undo is the 0th entry...
     Command_button.menu.entryconfig(0, state=DISABLED)

     Command_button.menu.add_command(label='New...', underline=0,
                                     command=new_file)

     # we can make bitmaps be menu entries too. File format is X11 bitmap.
     # if you use XV, save it under X11 bitmap format. duh-uh.,..
     Command_button.menu.add_command(
         bitmap="info")
         #bitmap='@/home/mjc4y/dilbert/project.status.is.doomed.last.panel.bm')
