Python Tkinter Edit Menu Window

问题

I'm trying to edit Menu window. How can i edit it?

This is for Windows.

from tkinter import *

Window = Tk()

MB = Menu(Window)
Window.config(menu=MB)

Menubar = Menu(MB)
MB.add_cascade(label="File", menu=Menubar)
Menubar.add_command(label="New File")

#Btn1 = Button(Menubar, width=20, text="Button").pack() #I failed.

Window.mainloop()

I tried Btn1 = Button(Menubar, width=20, text="Button").pack() But this one couldn't work.

回答1:

usually you add items to menu like this - but what are looking for?

window = Tk()
mb = Menu(window)  
menu_bar = Menu(mb, tearoff=0)  
menu_bar.add_command(label="New")  
menu_bar.add_command(label="Open")  
menu_bar.add_command(label="Save")  
menu_bar.add_command(label="Save as...")  
menu_bar.add_command(label="Close")  

menu_bar.add_separator()  

menu_bar.add_command(label="Exit", command=window.quit)  

mb.add_cascade(label="File", menu=menu_bar)

top.config(menu=mb)

回答2:

You cannot add arbitrary widgets to a menu. To add items to a menu you must use one of the following functions available on the Menu object:

add
add_command
add_cascade
add_checkbutton
add_radiobutton
add_separator

To add a textual label you can use add_command and set the command attribute to None.

All of these are documented with the Menu widget definition itself, and on just about any site that includes widget documentation.

If you're looking for a control of Menu Bar with Buttons you can do it. All of the code will be in the same file.py .Libraries in Python3 (For Python 2 change to import Tkinter as tk). Later you can redirect to each window with each menu with buttons.

import tkinter as tk
from tkinter import ttk

Global list of titles for

nombre_ventanas={'PageOne'}

One menubar, you need to add similar for each menu that you want to display. menubar_global, menubar1, menubar2, ...

def menubar_global(self, root, controller):

    menubar_global = tk.Menu(root)

    page_1 = tk.Menu(menubar_global, tearoff=0)

    # With Submenu for page_1

    page_1_1=tk.Menu(page_1 , tearoff=0)
    page_1_2=tk.Menu(page_1 , tearoff=0)

Main

if __name__ == "__main__":
    app = ControlWindow()
    app.mainloop()

Class for windows control

class ControlWindow(tk.Tk):

    def __init__(self, *args, **kwargs):

        tk.Tk.__init__(self, *args, **kwargs)

        container = tk.Frame(self)

        container.pack(side="top", fill="both", expand=True)

        container.grid_rowconfigure(0, weight=1)
        container.grid_columnconfigure(0, weight=1)

        self.frames = {}

        self._nombre_ventanas = nombre_ventanas

        for F in self._nombre_ventanas:

            F = eval(F)
            frame = F(container, self)
            self.frames[F] = frame
            frame.grid(row=0, column=0, sticky="nsew")

        # First window
        self.show_frame(Login)

    def show_frame(self, cont):
        frame = self.frames[cont]
        frame.tkraise()

        # Title for each page
        self.title(titulo_ventanas[cont._name_for_menu_bar])

        # Here you can add if-sentece for each menubar that you want 
        if cont._name_for_menu_bar != "PageOne":

            # Menu bar
            print("show_frame", cont)
            menubar = frame.menubar(self)
            self.configure(menu=menubar)

        else:
            menubar = 0
            self.configure(menu=menubar)

class Ventana_proveedores(tk.Frame):

    _name_for_menu_bar = "Ventana_proveedores"

    _config = configuracion

    def __init__(self, parent, controller):
        tk.Frame.__init__(self, parent)

        self.controller = controller

        tk.Button(self, text='Regresar', font=FONT_LABELFRAME,
                command=lambda: controller.show_frame(Ventana_gerente)).grid(row=0, column=0)

    def menubar(self, root):
        return menubar_global(self, root, self.controller)

Later Each Page need to have this configuration

class PageOne(tk.Frame):

    _name_for_menu_bar = "PageOne"


    def __init__(self, parent, controller):
        tk.Frame.__init__(self, parent)

        self.controller = controller

    def menubar(self, root):
        return menubar_global(self, root, self.controller)
