An object that supports editing zero or more properties of a bean. By implementing IsEditor , the Widgets need only implement the single asEditor method, which isolates the Widgets from any API changes that may occur in the component Editor logic. If the Widget contains multiple sub-Editors is a simple, static hierarchy, use the Editor interface. Sign up using Email and Password. Found some additional comments on GWT Editors.

The wildcard is used so that the presenter does not need to know the concrete view implementation: If the value will affect with sub-editors are or are not provided to the framework, they should be initialized or nullified at this time. LeafValueEditor LeafValueEditor is used for non-object, immutable, or any type that the Editor framework should not descend into.

An instance field with at least package visibility whose name exactly is the property that will be edited or propertyNameEditor. Sign up ediotr Email and Password.

Call the flush method on the driver to copy Editor state into the bean hierarchy. This driver type requires edtor RequestContext in order to automatically call RequestContext. Very large objects Q: I’m using gwt-platform and tried to implement GWT’s editor framework. Editor delegates Every Editor has a peer EditorDelegate that provides framework-related services to the Editor.


GWT 2.1 Editors

General workflow Instantiate and initialize the Editors. The view interface extends the editor interface for the Model object public interface MyView extends View, Quickstart Import the com.

This would mean that the View knows its model, too kind of There are some answers around the web, that say I have to inject the EditorDriver somehow into the Presenter, but I don’t know how to do this To reduce the amount of generics boilerplate, most types are equipped with a static of method to instantiate the adapter type.

An approach similar to what was used in an earlier version of the Expenses sample worked for me:. An object that supports editing zero or more properties of a bean.

LeafValueEditor is used for non-object, immutable, or any type that the Editor framework should not descend into.

The GWT distribution provides the following Editor adapter classes that provide reusable logic. The only expected behavior of an Editor is that it will provide access to its sub-Editors via one or more of the following mechanisms:.

If anyone has any improvements on this, I’m glad to hear. As Thomas Broyer puts it in his answer to another Editor question:.


SimpleBeanEditorDriver (GWT Javadoc)

A CompositeEditor that is editing an indexable datastructure, such as a Listmight eritor [index] for this method. At runtime, if any of these sub-editors is null, it will simply be ignored. There are several kinds of editors:. This makes the Editor framework a very good friend of UiBinder! Similarly to UiBinderyou’ll declare an interface extending one of these with generic parameters.

An Editor may be composed of an arbitrary number of sub-Editors that edit the properties of a bean. Eidtor hope that there’s another solution.


But I don’t get gqt working from within the presenter. Benjamin M 8, 15 73 All of these core Editor sub-interface can be mixed at will. Because everything is done at compile-time by inspecting classes, it means everything is based on the types you use in your interface declaration and for sub-editors, see below, the field and method declarations.

HasEditorErrors indicates that the Editor wishes to receive any unconsumed errors reported by sub-Editors through EditorDelegate.
