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

[jacek]

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.

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

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

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.
