java.lang.Object | +--javax.swing.DefaultButtonModel
The default implementation of a Button component's data model.
Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. A future release of Swing will provide support for long term persistence.
Field Summary | |
protected String |
actionCommand
|
static int |
ARMED
Indicates partial commitment towards choosing the button. |
protected ChangeEvent |
changeEvent
Only one ChangeEvent is needed per button model instance since the event's only state is the source property. |
static int |
ENABLED
Indicates that the button can be selected by an input device (such as a mouse pointer). |
protected ButtonGroup |
group
|
protected EventListenerList |
listenerList
|
protected int |
mnemonic
|

Indicates that the button has been "pressed" (typically, when the mouse is released). |
static int |
ROLLOVER
Indicates that the mouse is over the button. |
static int |
SELECTED
Indicates that the button has been selected. |
