How did you declare the slot? Does the class contain the Q_OBJECT macro?

[seldeepchan]

ya..i declared Q_Object .but still i am getting like

Object::connect: No such slot Einsteig::CTANDatumeingabeDlg::OnUpdateFeld1()
Object::connect: (sender name: 'm_ctrlSpinFeld1')
Object::connect: (receiver name: 'Datum')
Object::connect: No such slot Einsteig::CTANDatumeingabeDlg::OnUpdateFeld2()
Object::connect: (sender name: 'm_ctrlSpinFeld2')
Object::connect: (receiver name: 'Datum')
Object::connect: No such slot Einsteig::CTANDatumeingabeDlg::OnUpdateFeld3()
Object::connect: (sender name: 'm_ctrlSpinFeld3')
Object::connect: (receiver name: 'Datum')

Could you show us the declaration of Einsteig::CTANDatumeingabeDlg?

[seldeepchan]

class CTANDatumeingabeDlg : public QDialog,Ui_Datum
{
Q_OBJECT

public:
CTANDatumeingabeDlg(QWidget* pParent = NULL);
}

I don't see any slots being declared there. Where did you declared OnUpdateFeldN()?
