有人知道我可以在哪里找到有关 glade 上的 Switch Widget 的文档吗?
我尝试在 GTK 网站上查找,但没有它的条目。

感谢 Timo 为我指明了正确的方向。我很喜欢 askubuntu!
基本上我的问题是,默认情况下,连接函数会将窗口的对象、小部件的对象和活动状态推送到您在回调上运行的任何函数。
这是之前的样子:
self.daymon.connect("notify::active", self.toggle_day("mon"))
之后的情况如下:
self.daymon.connect('notify::active', self.toggle_day, "mon")
运行以下函数时,后者效果很好:
def toggle_day(self, widget, active, day):
if widget.get_active():
state = True
else:
state = False

干得好:http://developer.gnome.org/gtk3/stable/GtkSwitch.html
包含所有小部件和更多有用信息的完整参考:http://developer.gnome.org/gtk3/stable/
GtkSwitch 只有一个信号,activate
。根据文档,您不应该直接连接到它:
应用程序永远不应该连接到该信号,而应该使用notify::active信号。
因此连接应该很简单:
switch.connect('notify::active', _switch_active_changed_cb)
该notify::foo
原理可用于任何小部件,它实际上监听属性的变化。
阅读有关连接信号的更多信息文档。
