Python使用Gtk开关启动和停止连续函数

import gi
gi.require_version('Gtk', '3.0')
from gi.repository import Gtk, GLib

def on_window_closed(window):
    Gtk.main_quit()

window = Gtk.Window()
window.connect("destroy", on_window_closed)

def on_switch_activated(switch, gparam):
    if switch.get_active():
        # 启动连续函数
        GLib.timeout_add(1000, continuous_function)
    else:
        # 停止连续函数
        GLib.source_remove(timer_id)

switch = Gtk.Switch()
switch.connect("notify::active", on_switch_activated)

def continuous_function():
    # 连续函数的逻辑
    return True  # 返回True以继续定时器

timer_id = None

window.add(switch)
window.show_all()

Gtk.main()
