public interface SpinnerModel
A model for a potentially unbounded sequence of object values. This model is similar to ListModel
however there are some important differences:
A SpinnerModel
has three properties, only the first is read/write.
value
nextValue
value
is the last element of the sequence. previousValue
value
is the first element of the sequence. value
property changes, ChangeListeners
are notified. SpinnerModel
may choose to notify the ChangeListeners
under other circumstances.JSpinner
, AbstractSpinnerModel
, SpinnerListModel
, SpinnerNumberModel
, SpinnerDateModel
Object getValue()
The current element of the sequence. This element is usually displayed by the editor
part of a JSpinner
.
setValue(java.lang.Object)
void setValue(Object value)
Changes current value of the model, typically this value is displayed by the editor
part of a JSpinner
. If the SpinnerModel
implementation doesn't support the specified value then an IllegalArgumentException
is thrown. For example a SpinnerModel
for numbers might only support values that are integer multiples of ten. In that case, model.setValue(new Number(11))
would throw an exception.
IllegalArgumentException
- if value
isn't allowedgetValue()
Object getNextValue()
Return the object in the sequence that comes after the object returned by getValue()
. If the end of the sequence has been reached then return null. Calling this method does not effect value
.
getValue()
, getPreviousValue()
Object getPreviousValue()
Return the object in the sequence that comes before the object returned by getValue()
. If the end of the sequence has been reached then return null. Calling this method does not effect value
.

, getNextValue()
void addChangeListener(ChangeListener l)
Adds a ChangeListener
to the model's listener list. The ChangeListeners
must be notified when models value
changes.
l
- the ChangeListener to addremoveChangeListener(javax.swing.event.ChangeListener)
void removeChangeListener(ChangeListener l)
Removes a ChangeListener
from the model's listener list.
l
- the ChangeListener to removeaddChangeListener(javax.swing.event.ChangeListener)
