public class ViewAction<E>
extends SecuredListAction
implements Action.ScreenOpeningAction, Action.ExecutableAction

Standard action for opening an editor screen in the read-only mode. The editor screen must implement the ReadOnlyAwareScreen interface.

The action instance can be parameterized using the nested properties XML element or programmatically in the screen controller.

setScreenClass

@StudioPropertiesItem
public void setScreenClass(@Nullable
                                                 java.lang.Class<? extends Screen> screenClass)

Sets the editor screen id.

Specified by:

setScreenClass in interface Action.ScreenOpeningAction

Parameters:

screenClass - the screen class to set

setScreenOptionsSupplier

public void setScreenOptionsSupplier(java.util.function.Supplier<ScreenOptions> screenOptionsSupplier)

Sets the editor screen options supplier. The supplier provides ScreenOptions to the opened screen.

The preferred way to set the supplier is using a controller method annotated with Install, e.g.:

 @Install(to = "petsTable.view", subject = "screenOptionsSupplier")
 protected ScreenOptions petsTableViewScreenOptionsSupplier() {
     return new MapScreenOptions(ParamsMap.of("someParameter", 10));
 }
 

Specified by:

setScreenOptionsSupplier in interface Action.ScreenOpeningAction

setScreenConfigurer

public void setScreenConfigurer(java.util.function.Consumer<Screen> screenConfigurer)

Sets the editor screen configurer. Use the configurer if you need to provide parameters to the opened screen through setters.

The preferred way to set the configurer is using a controller method annotated with Install, e.g.:

 @Install(to = "petsTable.view", subject = "screenConfigurer")
 protected void petsTableViewScreenConfigurer(Screen editorScreen) {
     ((PetEdit) editorScreen).setSomeParameter(someValue);
 }
 

Specified by:

setScreenConfigurer in interface Action.ScreenOpeningAction

setAfterCloseHandler

public void setAfterCloseHandler(java.util.function.Consumer<Screen.AfterCloseEvent> afterCloseHandler)

Sets the handler to be invoked when the editor screen closes.

The preferred way to set the handler is using a controller method annotated with Install, e.g.:

 @Install(to = "petsTable.view", subject = "afterCloseHandler")
 protected void petsTableViewAfterCloseHandler(AfterCloseEvent event) {
     if (event.closedWith(StandardOutcome.COMMIT)) {
         System.out.println("Committed");
     }
 }
 

Specified by:

setAfterCloseHandler in interface Action.ScreenOpeningAction

setAfterCommitHandler

public void setAfterCommitHandler(java.util.function.Consumer<E> afterCommitHandler)

Sets the handler to be invoked when the editor screen commits the entity if "enable editing" action was executed.

The preferred way to set the handler is using a controller method annotated with Install, e.g.:

 @Install(to = "petsTable.view", subject = "afterCommitHandler")
 protected void petsTableViewAfterCommitHandler(Pet entity) {
     System.out.println("Committed " + entity);
 }
 

setTransformation

public void setTransformation(java.util.function.Function<E,E> transformation)

Sets the function to transform the committed in the editor screen entity (if "enable editing" action was executed) before setting it to the target data container.

The preferred way to set the function is using a controller method annotated with Install, e.g.:

 @Install(to = "petsTable.view", subject = "transformation")
 protected Pet petsTableViewTransformation(Pet entity) {
     return doTransform(entity);
 }
