TITLE = "ToggleButton"
DESCRIPTION = """
A Gtk.ToggleButton is a Gtk.Button which will remain “pressed-in” when clicked.
Clicking again will cause the toggle button to return to its normal state
"""
import gi

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


class ToggleButtonWindow(Gtk.Window):
    def __init__(self):
        Gtk.Window.__init__(self, title="ToggleButton Demo")
        self.set_border_width(10)

        hbox = Gtk.Box(spacing=6)
        self.add(hbox)

        button = Gtk.ToggleButton("Button 1")
        button.connect("toggled", self.on_button_toggled, "1")
        hbox.pack_start(button, True, True, 0)

        button = Gtk.ToggleButton("B_utton 2", use_underline=True)
        button.set_active(True)
        button.connect("toggled", self.on_button_toggled, "2")
        hbox.pack_start(button, True, True, 0)

    @staticmethod
    def on_button_toggled(button, name):
        if button.get_active():
            state = "on"
        else:
            state = "off"
        print("Button", name, "was turned", state)


def main():
    win = ToggleButtonWindow()
    win.connect("delete-event", Gtk.main_quit)
    win.show_all()
    Gtk.main()


if __name__ == "__main__":
    main()

创建两个Gtk.ToggleButton，都绑定“toggled”信号到on_button_toggled方法，并且分别传递参数“1”和“2”

button = Gtk.ToggleButton("Button 1")
        button.connect("toggled", self.on_button_toggled, "1")

@staticmethod
def on_button_toggled(button, name):
    if button.get_active():
        state = "on"
    else:
        state = "off"
    print("Button", name, "was turned", state)

使用get_active（）方法获知ToggleButton当前状态，如果返回值为True则表示开启状态，如果为False表示关闭状态
