[Qt-interest] Get children from layout

[David Boosalis]

Thats because getChild is a method of QObject.  And it appears your layout
is not the parent, hence it has no children.  You could use
QLayout::itemAt().  I think a better solution is that when you put your
widgets in a the layout you also put them in a QList and use it for your
book keeping
