i am using spin box.when ever any changes in spinbox that is updatation in the spin box it should call one more funtion for validate the value what we entered.

connect(m_ctrlSpinFeld1, SIGNAL(valueChanged(int)),
		this, SLOT(OnUpdateFeld1()));

connect(m_ctrlSpinFeld1, SIGNAL(valueChanged(int)),
		this, SLOT(OnUpdateFeld1()));
