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：

代码部分：

number = 0
# some miscellaneous callbacks
def new_file():
    global number
    number += 1
    tk = Tk()
    tk.geometry('300x300')
    tk.title('Demo %s'%number)

def open_file():
    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)

                                    font='-*-helvetica-*-r-*-*-*-180-*-*-*-*-*-*',
                                    command=print_something)

    # 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')

    # this is just a line
    Command_button.menu.add('separator')

    # change the color
    Command_button.menu.add_command(label='Quit', underline=0,

                                    command=Command_button.quit)

    # set up a pointer from the file menubutton back to the file menu
    Command_button['menu'] = Command_button.menu

    return Command_button

# make a menu bar
mBar = Frame(root, relief=RAISED, borderwidth=2)

Command_button = makeCommandMenu()


# finally, install the buttons in the menu bar.
# This allows for scanning from one menubutton to the next.
mBar.tk_menuBar(Command_button)

root.iconname('menu demo')
