dojox.mvc.Group

Authors:Rahul Akolkar, Ed Chatelain
Developers:Rahul Akolkar, Ed Chatelain
since:V1.7

A simple model-bound container widget with single-node binding to a data model. A group is usually bound to an intermediate dojo.Stateful node in the data model. Child dijits or custom view components inside a group inherit their parent data binding context from it.

Parameters

Parameter Type Default Description
target dojo/Stateful   The data model used for relative data binding.

Examples

Declarative example

var model;

        The group container denotes some logical grouping of widgets and also serves
        to establish a parent data binding context for its children.
        The target attribute for the outermost container obtains the binding from the
        "page scope" itself.
-->
<!--
        For convenience, the widget hierarchy matches the data hierarchy
        (see JSON literal above).
        In this implementation, the child attributes are simple property names
        of the parent binding context.
