GWT EDITOR DRIVER

Found some additional comments on GWT Editors. This is known as the Editor contract. To use them together so that your objects are displayed in the editors, you’ll use an editor driver. If you then use the generated code on a subclass of the editor for instance, only the bits inherited and possibly overridden from the declared editor type. Not all drivers may support subscription. The driver is responsible for descending into the Editor hierarchy to propagate data.

GWT WYSIWYG Editor

Email Required, but never shown. LeafValueEditor LeafValueEditor is used for non-object, immutable, or any type that the Editor framework should not descend into. An object that supports editing zero or more properties of a bean.

The GWT Editor framework makes extensive use of code generation. But before you edit an object, you’ll first have to initialize the editor driver with the actual editor instance to be used. If the composite editor is editing a Collection, this method solves the problem of having no sub-Editors available to examine for an deitor Collection.

At the moment I tried this without success: CompositeEditor CompositeEditor allows an unknown number of homogenous sub-Editors to be added to the Editor hierarchy at runtime. I hope that there’s another solution. The IsEditor interface is intended to be used when a view type is reusing an Editor behavior provided by an external type. Arbitrary data can be attached to the generated EditorError by using the userData parameter.

CompositeEditor allows an unknown number of homogenous sub-Editors to be added to the Editor hierarchy at runtime. Each editor is bound to a type of object that it can edit.

Editors are a graph of objects used to edit objects. If You’ve done some improvements on this please let me know.

SimpleBeanEditorDriver (GWT Javadoc)

As Thomas Broyer puts it in his answer to another Editor question:. One solution is the following: Most widgets displaying or editing values are already editors most are actually IsEditor s of editor adapters: How can I edit objects with a large number of properties?

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.

If the Widget contains ediitor sub-Editors is a simple, static hierarchy, use the Editor interface. But I don’t get it working from within the presenter.

As Thomas Broyer puts it in his answer to another Editor question: Editor subtypes In addition to the Editor interface, the Editor framework looks for these gw interfaces to provide basic building blocks for more complicated Editor behaviors. The SimpleBeanEditorDriver provides just that: MVP says that you use the presenter to completely seperate the model from the view.

The Editor framework uses a Flow Synchronization pattern: Found some additional comments on GWT Editors. Changes made to the structure of the List returned by ListEditor. There are several kinds of editors:.

Editor module in your gwt. The basic Editor type is simply a parameterized marker interface that indicates ediyor a type conforms to the editor contract or informal protocol.

A CompositeEditor that is editing an indexable datastructure, such as a Listmight return [index] for this method. 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:. A field or method will be treated as an editor if its type implements the Editor marker interface or one of its subinterfaces, see below or the IsEditor interface.

This makes the Editor framework a very good friend of UiBinder!
