7 * @class Roo.XComponent
8 * A delayed Element creator...
9 * Or a way to group chunks of interface together.
10 * technically this is a wrapper around a tree of Roo elements (which defines a 'module'),
11 * used in conjunction with XComponent.build() it will create an instance of each element,
12 * then call addxtype() to build the User interface.
14 * Mypart.xyx = new Roo.XComponent({
16 parent : 'Mypart.xyz', // empty == document.element.!!
20 disabled : function() {}
22 tree : function() { // return an tree of xtype declared components
26 xtype : 'NestedLayoutPanel',
33 * It can be used to build a big heiracy, with parent etc.
34 * or you can just use this to render a single compoent to a dom element
35 * MYPART.render(Roo.Element | String(id) | dom_element )
42 * Roo is designed primarily as a single page application, so the UI build for a standard interface will
43 * expect a single 'TOP' level module normally indicated by the 'parent' of the XComponent definition being defined as false.
45 * Each sub module is expected to have a parent pointing to the class name of it's parent module.
47 * When the top level is false, a 'Roo.BorderLayout' is created and the element is flagged as 'topModule'
48 * - if mulitple topModules exist, the last one is defined as the top module.
52 * When the top level or multiple modules are to embedded into a existing HTML page,
53 * the parent element can container '#id' of the element where the module will be drawn.
57 * Unlike classic Roo, the bootstrap tends not to be used as a single page.
58 * it relies more on a include mechanism, where sub modules are included into an outer page.
59 * This is normally managed by the builder tools using Roo.apply( options, Included.Sub.Module )
61 * Bootstrap Roo Included elements
63 * Our builder application needs the ability to preview these sub compoennts. They will normally have parent=false set,
64 * hence confusing the component builder as it thinks there are multiple top level elements.
