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.

|---|---|
void |
addChangeListener(ChangeListener l)
Adds a ChangeListener to the model's listener list. |
Object |
getNextValue()
Return the object in the sequence that comes after the object returned by getValue(). |
Object |
getPreviousValue()
Return the object in the sequence that comes before the object returned by getValue(). |
Object |
getValue()
The current element of the sequence. |
void |
removeChangeListener(ChangeListener l)
Removes a ChangeListener from the model's listener list. |
void |
setValue(Object value)
Changes current value of the model, typically this value is displayed by the editor part of a JSpinner. |
| Method Detail |
|---|
Object getValue()
editor part of a JSpinner.
setValue(java.lang.Object)void setValue(Object value)
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()
getValue(). If the end of the sequence has been reached
then return null. Calling this method does not effect value.
getValue(),
getPreviousValue()Object getPreviousValue()
getValue(). If the end of the sequence has been reached then
return null. Calling this method does not effect value.
getValue(),
getNextValue()void addChangeListener(ChangeListener l)
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)
ChangeListener from the model's listener list.
l - the ChangeListener to removeaddChangeListener(javax.swing.event.ChangeListener)
