Warning: QObject::connect: Connecting from XXX to COMPAT slot (YYY)

QObject::connect: Connecting from QGroupBox::toggled(bool) to COMPAT slot (QSlider::setShown(bool))

QObject::connect: Connecting from QGroupBox::toggled(bool) to COMPAT slot (QSlider::setShown(bool))

Do I need to worry about this warning? The connection works anyway, but I don't understand if i am doing something wrong or Qt is at fault here. I simply connected a QGroupBox's toggled(bool) with a child QWidget's setVisible(bool) in designer.

Thanks

BTW: I am using qt-win-opensource-src-4.3.4 with VC++
