Arbitrary data can be attached to the generated EditorError by using the userData parameter. I couldn’t find a way for the view implementation to NOT know the model but I don’t think it’s really necessary. Whether or not these editors are displayed all at the same time or sequentially is a user experience issue. The Editor framework allows multiple Editors to edit the same object: But I don’t get it working from within the presenter. Similarly to UiBinder , you’ll declare an interface extending one of these with generic parameters. Most Editors are Widgets, but the framework does not require this.

Arbitrary data can be attached to the generated EditorError by using the userData parameter.
GWT 2.1 Editors
Can I use Editors to view read-only data? Editors that directly mutate their peer object should do so only when flush is called in editir to allow an edit workflow to be canceled. Every Editor has a peer EditorDelegate that provides framework-related services to the Editor. CompositeEditor CompositeEditor allows an unknown number of homogenous sub-Editors to fditor added to the Editor hierarchy at runtime. In this case, the Editor framework will ignore these sub-editors.
Not all drivers may support subscription.
In addition to the Editor interface, the Editor framework looks for these specific interfaces to provide basic building blocks for more complicated Editor behaviors. But I don’t get it working from within the presenter. RequestFactoryEditorDriver has a convenience display method as well. This section will document these interfaces and provide examples of how the Editor framework will interact with the API at runtime. The wildcard is used so that the presenter does not need to know the concrete view implementation:.
Editor subtypes In addition to the Editor interface, the Editor framework looks for these specific interfaces to provide basic building blocks for more complicated Editor behaviors.
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: Finally, editors are any class that implement the Editor marker-interface or the IsEditor interface.
GWT WYSIWYG Editor
There are several kinds of editors:. Marco Jakob 10 LeafValueEditor is used for non-object, immutable, or any type that the Editor framework should not descend into. This is a great solution. It seems that it might just not be possible to completely separate the model.
If you had a BagOfState type with many properties, it might make sense to write several Editor types that edit conceptually-related subsets of the properties: Support arbitrary composition of Editors.
If you had a BagOfState type with many gwwt, it might make sense to write several Editor types that edit conceptually-related subsets of the properties:.
GWT WYSIWYG Editor ()
By implementing IsEditorthe Widgets need only implement the single asEditor method, which isolates the Widgets from any API changes that may occur in the component Editor logic. How can I edit objects with a large number of properties? I hope that there’s another solution. An approach similar to what was used in an earlier version of the Expenses sample worked for me: At the moment I tried this without success: Sign up using Email and Password.
Similarly to UiBinderyou’ll declare an interface extending one of these with generic gqt. If the composite editor is editing a Collection, this method solves the problem of having no sub-Editors available to examine for an empty Collection. The Editor framework allows multiple Editors to edit the same object:. As Thomas Broyer puts it in his answer to another Editor question: Both editor driver interfaces have two generic parameters: OptionalFieldEditor can be used with nullable or resettable bean properties.
