Question

我正在尝试在笔记本中使用tkinter。它有两个按钮，一个只显示一个文本，另一个应该打开一个地图（ipyleaflet）。单击“Say hello”按钮时，将显示输出。但是在“地图”的情况下也不会发生同样的情况。这是一个限制吗？

import tkinter as tk

from ipyleaflet import (
     Map,
     Marker,
     TileLayer, ImageOverlay,
     Polyline, Polygon, Rectangle, Circle, CircleMarker,
     GeoJSON,
     DrawControl
)

def map_print():
    m = Map(zoom=0)
    dc = DrawControl()
    def handle_draw(self, action, geo_json):
        print(action)
        print(geo_json)
    dc.on_draw(handle_draw)
    m.add_control(dc)
    return(m)

class Application(tk.Frame):
    def __init__(self, master=None):
        super().__init__(master)
        self.pack()
        self.create_widgets()

    def create_widgets(self):

        self.hello= tk.Button(self)
        self.hello["text"] = "Say Hello"
        self.hello["command"] = self.say_hello
        self.hello.pack(side="top")

        self.hey= tk.Button(self)
        self.hey["text"] = "Map"
        self.hey["command"] = self.say_map
        self.hey.pack(side="top")


        self.quit = tk.Button(self, text="QUIT", fg="red",
                              command=root.destroy)
        self.quit.pack(side="bottom")

    def say_map(self):        
        M=map_print()
        M

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


root = tk.Tk()
app = Application(master=root)
app.mainloop()

在tkinter中使用ipyleaflet
