Method Details

setListener

public void setListener(FieldListener listener)

Atribui um listener para este controller estender ou sobrescrever seus eventos. Se não for atribuído nenhum, é usado FieldListener.EMPTY.

setNullIfNotValid

public void setNullIfNotValid()

Valida o campo atual, e, se não estiver válido, o apaga. Isto é especialmente útil para evitar atribuir a campos de formulários um valor que não seja válido.

validar

public void validar()
             throws Exception

The validar event is invoked whenever input is accepted on the field (in add/update/delete mode). Use this event to validate if the input is valid.

Specified by:

validar in interface FieldListener

Throws:

Exception - when the validation fails

afterField

public void afterField()
                throws Exception

The afterField event is invoked (in add/update/delete mode) after the field is current -- that is as some other field becomes current.

Specified by:

afterField in interface FieldListener

Throws:

Exception

beforeField

public void beforeField()
                 throws Exception

The beforeField event is invoked each time the field becomes current (in add/update/delete mode).

Specified by:

beforeField in interface FieldListener

Throws:

Exception

initField

public void initField()
               throws Exception

The initField event section is invoked on each field when the form is activated.

Specified by:

initField in interface FieldListener

Throws:

Exception

onDataAccept

public void onDataAccept()
                  throws Exception

The onDataAccept event is invoked whenever input is accepted on the field (in add/update/delete mode).

Specified by:

Throws:

Exception

onSearchRangeAccept

public void onSearchRangeAccept()
                         throws Exception

The onSearchRangeAccept event is invoked whenever input is accepted on the field in FIND mode.

Specified by:

onSearchRangeAccept in interface FieldListener

Throws:

Exception

whenValueChanges

public void whenValueChanges()
                      throws Exception
