@Documented @Retention(value=RUNTIME) @Target(value=METHOD) public @interface Action
Marks a method that will be used to define a Swing
Action object's actionPerformed
method. It also identifies the resources that
will be used to initialize the Action's properties.
Additional @Action parameters can be used
to specify the name of the bound properties (from the
same class) that indicate if the Action is to be
enabled/selected, and if the GUI should be blocked
while the Action's background Task is running.
The ApplicationActionMap class creates an
ActionMap that contains one ApplicationAction
for each @Action found in a target or "actions" class.
Typically applications will use getActionMap to
lazily construct and cache ApplicationActionMaps, rather than
constructing them directly. By default the ApplicationActionMap's
key for an @Action is the
name of the method. The name parameter can be used to
specify a different key.
The ApplicationAction's properties are initialized with
resources loaded from a ResourceBundle with the same name as the
actions class. The list of properties initialized this way
is documented by the ApplicationAction's
constructor.
The method marked with @Action, can have no parameters,
or a single ActionEvent parameter. The method's return type
can be void or Task. If the return type
is Task, the Task will be executed by the ApplicationAction's
actionPerformed method.
