[pygtk] Defining and using my own signals

[Saeed Rasooli]

import gobject
gobject.type_register(MyWidgetClass)
gobject.signal_new('my-signal-name', MyWidgetClass,
gobject.SIGNAL_RUN_LAST, gobject.TYPE_NONE, [])

In the MyWidgetClass, use:
self.emit('my-signal-name')
to emit that signal. And if you defined arguments for that
signal(using gobject.signal_new) give that arguments to emit function.
for example:

gobject.signal_new('my-signal-name', MyWidgetClass,
gobject.SIGNAL_RUN_LAST, gobject.TYPE_NONE, [int, str])

self.emit('my-signal-name', 5, 'test') ## two arguments [int, str]
