[SOLVED]How to get emitter of a signal in the slot?

[wecing]

Hi,

Currently I have five QListEdit widgets in a widget of my program.
I need to connect their editingFinished() signal to a shared slot, but they have to be distinguished inside the slot.

I guess it's impossible to get emitter of a signal in Qt, but writing five clue slots which will call the shared slot with an extra parameter is too ugly.

So, any ideas?

UPDATE: Nevermind. I just found the "Advanced Signals and Slots Usage" section in "Signals & Slots".

I hope you've found QSignalMapper.

QObject::sender() will return you a pointer to signal sender when you call it from the slot.

Thanks guys, but both QSignalMapper and QObject::sender() are referred in the section I mentioned...

Be aware that sender() returns a null pointer, if the slot is called directly (i.e. not using a signal/slot connection).
