Class ComponentResizedAction

java.lang.Object
  extended by uic.model.UICSimpleAction
      extended by uic.action.SwingAction
          extended by uic.action.ComponentResizedAction
All Implemented Interfaces:
ComponentListener, EventListener

public class ComponentResizedAction
extends SwingAction
implements ComponentListener

An event to respond to a widget being shown on screen. Notice that the default version uses the DirectPolicy. Using this class is easy; just call:

new ComponentResizedAction(this, "firedSlot").add(childComponent); 
This has the result that every time the widget rescaled 'firedSlot' on object 'this' will be called.

Constructor Detail

ComponentResizedAction

public ComponentResizedAction(Object targetObject,
                              String targetMethod)
Create a new ComponentResizedAction.

Parameters:
targetObject - on which object should the target method be invoked
targetMethod - wich method on the targetObject should be invoked

ComponentResizedAction

public ComponentResizedAction(Object targetObject,
                              String targetMethod,
                              UICSimpleAction.Arguments arguments)
Create a new ComponentResizedAction.

Parameters:
targetObject - on which object should the target method be invoked
targetMethod - wich method on the targetObject should be invoked
arguments - to be used in finding the targetMethod signature

UICSimpleAction.setTarget(Object,String,uic.model.UICSimpleAction.Arguments)
Method Detail

add

public ComponentResizedAction add(Component source)
Add an Component object to this action.

Parameters:
source - the component that will be become visible later.

getTargetSignatures

protected List getTargetSignatures()
Description copied from class: UICSimpleAction
Return a List object with instances of the Arguments class. Extending classes should implement this to return all the target method signatures that are searched for should the user create an action without an Arguments instance.

An example implementation could be this:

  List result = new ArrayList(1);
  result.add( new Arguments().addArgument("Source") );
  return result;
This will result in a call to UICSimpleAction.getArgumentClass(java.lang.String) with the string "Source" which returns a Class instance. In our example that would be java.lang.Object.

The result of this would be that a call to setTarget will try to find a method with an argument of type Object, and will search again if that is not found without any arguments.

Overrides:
getTargetSignatures in class UICSimpleAction
Returns:
a List object with instances of the Arguments class.
See Also:
UICSimpleAction.getArgumentValue(java.util.EventObject, java.lang.String), UICSimpleAction.getArgumentClass(java.lang.String)

getArgumentValue

protected Object getArgumentValue(EventObject source,
                                  String argumentType)
Description copied from class: UICSimpleAction
For the uniquely defined argumentType (as also used in UICSimpleAction.getTargetSignatures()) return the value. This method will always return 'null'; Extending actions can define various argumentType strings that can be used as an argument in the call to the target method of this action. The user decides on construction of the action which argumentTypes are to be used, if a certain value is requested to be sent to the targetMethod a call is made to this method to find its value based on the source event.

Note that base types can not be returned, since they are instances of object; you should wrap these in their object re-presentation (an Integer object for an int).

Overrides:
getArgumentValue in class UICSimpleAction
Parameters:
source - the event that caused the action to be fired. This is the event that the extending class passed to the execute method; so casting is fine.
argumentType - the uniquely defined name specifying the type of argument.
Returns:
the value to be passed to the taget method.

getArgumentClass

protected Class getArgumentClass(String argumentType)
Description copied from class: UICSimpleAction
For the uniquely defined argumentType (as also used in UICSimpleAction.getTargetSignatures()) return the Class. This method will always return 'null'; Extending actions can define various argumentType strings that can be used as an argument in the call to the target method of this action. The user decides on construction of the action which argumentTypes are to be used, if a certain value is requested to be sent to the targetMethod a call is made to this method to find the Class of the type.

Note that basetypes have a class of their own and you should return the correct one you expect the targetMethod to implement. returning Integer.class will search for an Integer; returing int.class will search for an int. This is important to note since the UICSimpleAction.getArgumentValue(java.util.EventObject, java.lang.String) method should return an Integer object in both cases.

Overrides:
getArgumentClass in class UICSimpleAction
Parameters:
argumentType - the uniquely defined name specifying the type of argument.
Returns:
the class of this argument to be found on the target method
