在ipython笔记本中集成tkinter事件循环

使用一个简单的tkinter gui像这样：

import tkinter as tk       

class Application(tk.Frame):              
    def __init__(self, master=None):
        tk.Frame.__init__(self, master)   
        self.grid()                       
        self.createWidgets()

    def printHello(self):
        print("Hello")

    def createWidgets(self):
        self.quitButton = tk.Button(self, text='Quit',
            command=self.quit)            
        self.quitButton.grid(row=1,column=0)    
        self.printButton = tk.Button(self, text='Print',command=lambda: self.printHello())         
        self.printButton.grid(row=1,column=1) 
app = Application()                        
app.master.title('Sample application')     
app.mainloop()

我正在尝试遵循本文档，以将事件循环与ipython笔记本的内核连接：https://ipython.org/ipython-doc/3/config/eventloops.html

但是我似乎不太了解它是如何工作的：@register_integration('tk')

我如何准确地连接事件循环？如果可以，如何处理连接的事件循环？

import tkinter as tk       

# Use your Tkinter widget as usual
class Application(tk.Frame):              
    def __init__(self, master=None):
        tk.Frame.__init__(self, master)   
        ...

# Here copy the skeleton from your given link ...
@register_integration('tk') 
def loop_tk(kernel):
...

    class Timer(object):
        def __init__(self, func):
            self.app = Tk()
            # self.app.withdraw()
            self.func = func

            # Last statement in __init__
            app = Application(self.app)                        
            app.master.title('Sample application')
        ...

if __name__ == "__main__":
    # Where does 'kernel' come from?
    # loop_tk(kernel)
    pass
