Annotation Type OnShow

@Retention(value=RUNTIME)
 @Target(value=METHOD)
 @Inherited
 @Documented
public @interface OnShow

View class accessible (public) methods annotated with this annotation will be called by view navigator right before the view is shown (rendered in target display component).

Annotated methods may provide an optional parameter of ViewNavigator.ViewNavigatorChangeEvent or default ViewChangeListener.ViewChangeEvent type to obtain informations about view navigation.

If more than one OnShow annotated method in present in view actual class or in it's class hierarchy, all these methods will be called and the following behaviour will be adopted:

• Methods will be called following class hierarchy, starting from the top (the first superclass after Object)
• For methods of the same class, no calling order is guaranteed

OnShow annotated methods have a similar function to that of View enter method.

Since:

4.0.0
