Hi,

When I doubleclick in item of QTableWidget it connect with given slot.
This slot for end of it functionality send signal, there is nothing after this signal.
Siganal run method which delete current class in center of MainWidget and show another.
But my program don't show this another, program close.

When I use button to emit these same signal everythink is ok.

Everything is in deleted widget.

Anybody knows why is that??
