dijit recursive getAllChildren example

_NestedChildren.js

define([
	"dojo/_base/array",
	"dojo/_base/declare",
	"dojo/_base/lang"
], function (arrayUtil, declare, lang) {
	return declare(null, {
		getAllChildren: function () {
			// puts all children into a flat array
			console.log(this.getNestedChildren);
			return (this.hasChildren()) ? this.getNestedChildren(this) : [];
		},
		 
		getNestedChildren: function (parent) {
			var children = parent.getChildren();
			var nested = [];
			arrayUtil.forEach(children, function(child) {
				if (child.hasChildren()) {
					nested.concat(lang.hitch(this, "getNestedChildren", child));
				}
			});
			return children.concat(nested);
		}
	});
});

registry.findWidgets(this.containerNode); https://github.com/dojo/dijit/blob/1.9.1/registry.js#L84-L113

oh, wait... findWidgets is not recursive. the deprecated getDescendants might be useful too but it finds all widgets rather than just the ones designated as "children"
