You can install an event filter to the labels.

For more details you can see the Qt documentation about Event filters

Example:

MainWidget::MainWidget(QWidget* parent) : QWidget(parent)
{
   ui.setupUi(this);
   theLabel->installEventFilter(this);
} 

bool MainWidget::eventFilter(QObject* o, QEvent* e)
{
    if(e->type() == QEvent::Resize)
    {
        //manage the resize event
    }
    return false;
}
