[Qt-interest] Calling parent Widget slot

[Donal O'Connor]

Hi Ender,

Good idea indeed.

I just tried changing the constructor to pass "MyParentWidgetType" class
instead of QWidget * parent.... and created a MyParentWidgetType * m_parent
member variable and called the status from this and that worked fine without
segmentation fault. Quite strange, I thought both ways were same in theory.

Over all though, the signal/slot method is better idea. I've implemented it
and it works perfectly.

Cheers!

Regards,
Donal
