Question

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。
