如何在一个窗口中打开多个 Tkinter 窗口 [英] How to Open Multiple Tkinter windows in one window

问题描述

我有两个或多个 python Tkinter 文件.每个文件打开一个窗口，如何在一个主窗口中运行所有 Tkinter 窗口功能.

I am having two or more python Tkinter files. Each file is opening one window, how can run all the Tkinter windows functionality in one main window.

例如:我有两个文件，一个是 usbcam.py，它将打开 USB 摄像头并提供视频流，另一个是 ipcam.py，它打开 IP 摄像头并提供实时流.这两个文件分两个打开windows 如何使它在一个窗口中工作

Ex : I have two files one is usbcam.py which will open USB camera and give the video steaming and the other one is ipcam.py it opens the IP camera and give the live streaming.This two files are opening in two windows how can make this to work in one window

usbcam.py

    if root.quit_flag:
        root.destroy()  # this avoids the update event being in limbo
    else:

推荐答案

您需要将一个脚本指定为主脚本，然后您可以在其中导入另一个脚本.下面是一个使用 Frame 小部件的简单子类执行此操作的示例:

You need to designate one script as the main script, and in that one you can import the other. Here's an example of doing this using a simple subclass of the Frame widget:

主脚本 (tkA.py):

from Tkinter import *
from tkB import Right # bring in the class Right from secondary script


class Left(Frame):
    '''just a frame widget with a white background'''
    def __init__(self, parent):
        Frame.__init__(self, parent, width=200, height=200)
        self.config(bg='white')

if __name__ == "__main__":
    # if this script is run, make an instance of the left frame from here
    # and right right frame from tkB
    root = Tk()
    Left(root).pack(side=LEFT) # instance of Left from this script
    Right(root).pack(side=RIGHT) # instance of Right from secondary script
    root.mainloop()

辅助脚本(tkB.py):

from Tkinter import *


class Right(Frame):
    '''just a frame widget with a black background'''
    def __init__(self, parent):
        Frame.__init__(self, parent, width=200, height=200)
        self.config(bg='black')

if __name__ == "__main__":
    # if this script is run, just do this:
    root = Tk()
    Right(root).pack()
    root.mainloop()
