    frmFelps.getContentPane().add(lblFundo);
}

private void atualizador(){
    //TODO
}
}

I want to change the text on txtpnInscrito every time that atualizador() runs But i don't know how to do this. If i change the text directly in the button btnCasa it changes, but i want to make a refresher by time and utilize the same function to refresh when doing actions on buttons.

Thanks in advance. And sorry for the horrible english.

Answer 1

You need to make txtpnInscrito field of the class so that it's accessible in all your methods within your class
