You might need to post some code that shows what you're doing.

With signals and slots you can find out which object emitted the signal 
by calling self.sender() in the slot that receives it. You might be able 
to record this somewhere visible to your editMethod, although you don't 
say which object would have this method. 
 
If you post some fairly concise example code, we can probably work something 
out.
