Multiple Widgets of same class, one single thread for computation - adressing problem

[elcuco]

I found myself in that position a few months ago. Something like "QObject *sender" to be passed on the slots would save this problem...

As far as I know, Qt does not have such things.

It does. It's called QObject::sender(). Unfortunately, it would not help here as the OP's sender is always the same object.

@burn2themax - Have you considered using a signal multiplexor?

You can use this to exclusively choose the widget you are intrested into to receive your signals. no other widgets will be notified.

But of course it has: QObject::sender()

@jacek
I did a sample implementation with QEvent and... it works!! Thanks for this solution!

@Chicken Blood Machine
Thanks for the idea with the multiplexer! Seems to be an interesting concept for having multiple docs.
But in my situation the receiver-widget changes permanently, so I had to call "setCurrentObject" on and on. This produces too much overhead.
