      Hi,

      Your connect statements are completely wrong. You can't pass parameters like that.

      Try that instead:
      @connect(ui->comboBoxPet, SIGNAL (activated(QString)), ui->label1, SLOT (setText(QString)));@

      And please, have a look at Qt's documentation about Signals and Slots
