如何在Pygtk中创建新信号

class MyGObjectClass(gobject.GObject):
    __gsignals__ = {
      "some-signal": (gobject.SIGNAL_RUN_FIRST, gobject.TYPE_NONE, (object, )),
    }

gobject.signal_new

import gobject

class MyGObjectClass(gobject.GObject):
    ...

gobject.signal_new("signal-name", MyGObjectClass, gobject.SIGNAL_RUN_FIRST,
    None, (str, int))

here

from kiwi.utils import gsignal

class MyObject(gobject.GObject):
    gsignal('signal-name')
