Auto event object receiver selection
Message 1 in thread
Hi everybody,
Is there the posibility that an application through the user, defines the receiver of an event.
I mean I have a list containing objects that are bits from a HW, and the user can select one to turn on other bits in the same HW.
The user is selecting both, which bit wants to turn on and which bit is going to generate the event to turn on the first.
I'm using a thread to read the state of the bit, and to post event seems that QThread::postEvent(receiver,event) is the function that I need, but I don't know how the user can define the receiver and not the programmer inside the code.
Any idea?
I will be glad with your suggestions.
best regads
David R.

Hi,
I have a big doubt and I don't know if I'm naive, is it possible that an application auto defines an slot or an event receiver? I mean always I have to define the slot with slots like:
connect(sender,SIGNAL(),receiver,SLOT())
or QThread::post(receiver, event)
my doubt is if theres a way to make an auto definition of the receiver? so when the user selects an object from a list, this object becomes the receiver in that functions.
thanks
David R.

Not sure if i understood you correctly. Maybe you're looking for this: QMetaObject::connectSlotsByName
