问题
After reading "Using your signals" I am wondering if it is possible to connect the signals to "sinks" in an "anonymous" way?
In order words, if the example following (snippet from reference above):
aCar = Car()
aCar.connect('engine-started', myCallback)
Is it possible just to connect myCallback to all the signal engine-started sources in one go? Something along the lines of:
gbus.connect('engine-started', myCallback)
Of course gbus here is just an example.
回答1:
Yes, you can use gobject.add_emission_hook (g_signal_add_emission_hook).
