[Qt-interest] QTabWidget resize events on hidden tabs

[Giacomo]

Hi.
Can someone explain how QResizeEvents are delivered to hidden widgets of a 
QTabWidget.

I need to place QWidgets on the tabs of a QTabWidget, and to proportionally 
resize them when the QTabWidget is resized.

I do like this:

QTabWidget *tabW = new QTabWidget;
QWidget *tab1 = new QWidget(0);
QWidget *tab2 = new QWidget(0);
tabW->addTab(tab1);
tabW->addTab(tab2);
QLabel *l1 = new QLabel(tab1);
QLabel *l2 = new QLabel(tab2);

When I resize QTabWidget, I want to resize proportionally labels l2 and l1.
But if tab1 is visible, then it seems that resize events on tab2 have an 
invalid oldSize().

How can I do to cleanly resize widgets children of hidden tabs?

Thanks in advance.
