77 * for BC - use el in new code
83 * @cfg {Function|boolean} disabled
84 * If this module is disabled by some rule, return true from the funtion
89 * @cfg {String} parent
90 * Name of parent element which it get xtype added to..
96 * Used to set the order in which elements are created (usefull for multiple tabs)
102 * String to display while loading.
107 * A single item array - the first element is the root of the tree..
108 * It's done this way to stay compatible with the Xtype system...
114 * Set's the xowner value on all the children
115 * basically var _this= this.xmodule; can be used in any component..
116 * to refer to it's own xmodule
117 * @param xtype element.

135 * True when the builder has completed building the interface.
138 buildCompleted : false,
141 * @property topModule
142 * the upper most module - uses document.element as it's constructor.
150 * array of modules to be created by registration system.
151 * @type Roo.XComponent
158 * Register components to be built later.
159 * @param {Object} details about module
161 * This solves the following issues
162 * - Building is not done on page load, but after an authentication process has occured.
163 * - Interface elements are registered on page load
164 * - Parent Interface elements may not be loaded before child, so this handles that..
