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 ggwt method declarations.

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 SimpleBeanEditorDriver provides just that: Quickstart Import the com. On one hand you have an object graph that you want to display or edit, and on the other hand a set of widgets let’s call them editorswe’ll see the why later.

CompositeEditor CompositeEditor allows an unknown number of homogenous sub-Editors to be added to the Editor hierarchy at runtime. Marco Jakob 10 During a flush, editors have an opportunity to report errors that will be available as EditorError s. All of these core Editor sub-interface can be mixed at will.

An interface that the view should implement. But before you edit editorr object, you’ll first have to initialize the editor driver with the actual editor instance to be used. 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: This section will document these interfaces and provide examples of how the Editor framework will interact with the API at runtime.

Can I use Editors to view read-only data?

To reduce the amount of generics boilerplate, most types are equipped with a static of method to instantiate the adapter type. If You’ve done some improvements on this please let me know.

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

By implementing IsEditorthe Widgets need only implement the single asEditor method, which gtw the Widgets from any API changes that may occur in the component Editor logic.

Arbitrary data can be attached to the generated EditorError by using the userData parameter. 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: The Deitor framework allows multiple Editors to edit the same object:.
