Field Detail

value

protected Object value

The value of this option.

listeners

protected List<ValueChangeListener> listeners

List of listeners that are notified when the value of this option changes.

persistent

protected boolean persistent

Determines whether the value of this option should be saved in the user preferences.

Constructor Detail

AbstractOption

public AbstractOption()

Constructor provided as a convenience to facilitate the creation of option elements through reflexion.

Method Detail

getValue

public Object getValue()

The value of this option.

Specified by:

getValue in interface Option

Returns:

the value as an Object instance.

See Also:

Option.getValue()

setValue

public void setValue(Object value)

Set the value of this option.

Parameters:

value - the value as an Object instance.

addValueChangeListener

public void addValueChangeListener(ValueChangeListener listener)

Add a value change listener to this option's list of listeners.

Parameters:

listener - the listener to add to the list.

removeValueChangeListener

public void removeValueChangeListener(ValueChangeListener listener)

Remove a value change listener from this option's list of listeners.

Parameters:

listener - the listener to remove from the list.

fireValueChanged

public void fireValueChanged()

Notify all registered listeners that the value of this option has changed.

setupValueChangeNotifications

protected abstract void setupValueChangeNotifications()

Concrete subclasses must implement this method, so they can properly forward changes in the value edited by the underlying UI component/editor.

layoutComponents

protected JPanel layoutComponents(JComponent comp1,
                                  JComponent comp2)

Layout 2 components according to the specified layout constraints.

Parameters:

comp1 - the first component to layout.

comp2 - the second component to layout.

Returns:

a JPanel instance, enclosing the 2 components plus the filler.

                                  String constraint2)

Layout 2 components according to the specified layout constraints.

Parameters:

comp1 - the first component to layout.

constraint1 - the layout constraint for the 1st component.

comp2 - the second component to layout.

Specified by:

isPersistent in interface Option

Returns:

true if the value should be saved, false otherwise.

See Also:

Option.isPersistent()

setPersistent

public void setPersistent(boolean persistent)

Set whether the value of this option should be saved in the user preferences.

Parameters:

persistent - true if the value should be saved, false otherwise.
