推荐答案

举例说明您要做什么:

import tkinter as tk
from tkinter import ttk

class App(tk.Tk):
    def __init__(self):
        super().__init__()
        self.geometry("400x200")
        self.configure(background='black')
        self.overrideredirect(1)
        self.attributes("-topmost", True)

    def startMove(self,event):
        self.x = event.x
        self.y = event.y

    def stopMove(self,event):
        self.x = None
        self.y = None

    def moving(self,event):
        x = (event.x_root - self.x)
        y = (event.y_root - self.y)
        self.geometry("+%s+%s" % (x, y))

    def exit(self):
        self.destroy()


def save():
    print ('save')
    return None
def add():
    print('add')
    return None



class MenuBar(tk.Frame):
    def __init__(self, master=None):
        tk.Frame.__init__(self, master, bd=1, relief='raised')
        self.master=master
        self.configure(background='black',
                       cursor='hand2')

        file = tk.Menubutton(self, text='File',
                             background='black',
                             foreground='white',
                             activeforeground='black',
                             activebackground='white'
                             )
        file_menu = tk.Menu(file,tearoff=0)
        file_menu.add_command(label='save', command=save,
                              background='black',

                              )

        file.config(menu=file_menu)
        file.pack(side='left')

        edit = tk.Menubutton(self, text='Edit',

                             activeforeground='black',
                             activebackground='white'
                             )
        edit_menu = tk.Menu(edit,tearoff=0)
        edit_menu.add_command(label='add', command=add,
                              background='black',
                              foreground='white',
                              activeforeground='black',
                              activebackground='white'
                              )

        edit.config(menu=edit_menu)
        edit.pack(side='left')

        close = tk.Button(self, text='X', command=lambda:root.exit(),
                          background='black',
                          foreground='white')
        close.pack(side='right')

def show():
    print('show')
    return None
def ex_it():

class MainFrame(tk.LabelFrame):

        tk.LabelFrame.__init__(self, master, bd=1, relief='raised', text='MainFrame', background='black', foreground='white')
        self.master=master
        self.note = tk.Label(self, text='Your typed chars appear here:',

                             foreground='white',

        self.b_frame=tk.Frame(self, bg='black')

root = App()

menubar = MenuBar(root)

                 foreground="white",
                 fieldbackground="grey")

root.mainloop()

玩得开心！

首先，我使用类创建了 3 个对象，它们如下所示:

First, I've created 3 objects using classes and they look like this:

应用lication/我们从 Tk() 获取的窗口

The Application / our window that inharets from Tk()

class App(tk.Tk):
    def __init__(self):
        super().__init__()

然后是来自 Frame 的菜单栏，看起来像:

Then the Menubar which inharets from Frame and looks like:

class MenuBar(tk.Frame):
    def __init__(self, master=None):
        tk.Frame.__init__(self, master, bd=1, relief='raised')

以及从 tkinter 的 LabeFrame 类中引入的 MainFrame:

and the MainFrame which inharets from the LabeFrame class of tkinter:

class MainFrame(tk.LabelFrame):
    def __init__(self, master=None):
        tk.LabelFrame.__init__(self, master, bd=1, relief='raised', text='MainFrame', background='black', foreground='white')

要了解有关类和 init 方法的更多信息 [点击]了解语法 self. [点击]

让我们仔细看看应用程序:

Let's take a closer look to the App:

self.geometry("400x200")
self.configure(background='black')
self.overrideredirect(1)
self.attributes("-topmost", True)

使用几何方法，我们定义了width=400 和 height=200 以像素为单位.
然后我们用一行来配置背景:

with the geometry method we are define the width=400 and height=200 in pixels.
Then we configure the background with the line:

self.configure(background='black')

在此之后，我们使用 tkinter 的 overrideredirect 方法这显然是在做:

After this we use the overrideredirect method of tkinter which is clearly doing:

设置或获取覆盖重定向标志.如果非零，这可以防止装饰窗口的窗口管理器.换句话说，窗口将没有标题或边框，并且不能移动或通过普通方式关闭.

我们最终使用属性方法用于顶层并将最上面的参数设置为 true :

and we finally use the attributes method for Toplevels and set the argument topmost to true that does:

(Windows) 如果设置，这个窗口总是放在其他窗口之上视窗.请注意，在此版本中，此属性必须指定为-topmost".

使用 overrideredirect 后最大的问题是您无法再移动窗口，因为窗口管理器不再有边框/标题或菜单栏.所以我们需要自己携带使用这个代码:

The biggest problem after using overrideredirect is that you can't move your window anymore, cause there is no border/Title- or Menubar of the window manager anymore. So we need to carry it by ourself with using this code:

def startMove(self,event):
    self.x = event.x
    self.y = event.y

def stopMove(self,event):
    self.x = None
    self.y = None

def moving(self,event):
    x = (event.x_root - self.x)
    y = (event.y_root - self.y)
    self.geometry("+%s+%s" % (x, y))

此代码的作用是通过使用事件管理器

And what this code does is to get the current mouse postion by clicking/Button-1 with the event manger

event.x 或 event.y 表示:

event.x or event.y means:

当前鼠标位置，以像素为单位.

event.x_root 或 event.y_root 表示:

event.x_root or event.y_root means:

当前鼠标相对于左上角的位置屏幕，以像素为单位.

并通过从另一个中减去一个，我们得到偏移量，这是我们需要的几何方法移动".

and by substracting the one from the other we get the offset, that we need for our geometry method to "move".
