官网：https://remi.readthedocs.io/en/latest/

import remi.gui as gui
from remi import start, App


class MyApp(App):
    def main(self, name='world'):
        # margin 0px auto allows to center the app to the screen
        wid = gui.VBox(width=300, height=200, margin='0px auto')

        lbl = gui.Label("Close or reload the page, the console thread will stop automatically.")
        wid.append(lbl)

        # add the following 3 lines to your app and the on_window_close method to make the console close automatically
        tag = gui.Tag(_type='script')
        tag.add_child("javascript", """window.onunload=function(e){remi.sendCallback('%s','%s');return "close?";};""" % (
            str(id(self)), "on_window_close"))
        wid.add_child("onunloadevent", tag)

        # returning the root widget
        return wid

    def on_window_close(self):
        # here you can handle the unload
        print("app closing")
        self.close()


if __name__ == "__main__":
    start(MyApp)
