child-parent events management
Message 1 in thread
Hi all,
Is there any possibilities to construct 3 child widgets for a parent widget and automaticly receive events in the childs without forwarding them from the parent widget?
I tried with mousePressEvent and didn't work.

Yes,
Call installEventFilter(childObject) for parent object (in parent constructor, for instance), and then you can reimplement "virtual bool eventFilter ( QObject * watched,
QEvent * e )" for parent object. In this function you will receive events from 'this' object and from child.

I'm sorry, I've taken 'without' as 'with'...
But when you return false from eventFilter in child it shouldn't be forwarded to parent.
