public abstract class AbstractAction extends Object implements Action, Cloneable, Serializable
Action
interface. Standard behaviors like the get and set methods for Action
object properties (icon, text, and enabled) are defined here. The developer need only subclass this abstract class and define the actionPerformed
method. 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. As of 1.4, support for long term storage of all JavaBeans has been added to the java.beans
package. Please see XMLEncoder

will get fired in response to setting a bound property, e.g. setFont
, setBackground
, or setForeground
. Note that if the current component is inheriting its foreground, background, or font from its container, then no event will be fired in response to a change in the inherited property.
