/**
- * @class Roo.XComponent
- * A delayed Element creator...
- * Or a way to group chunks of interface together.
- * technically this is a wrapper around a tree of Roo elements (which defines a 'module'),
- * used in conjunction with XComponent.build() it will create an instance of each element,
- * then call addxtype() to build the User interface.
- *
- * Mypart.xyx = new Roo.XComponent({
-
- parent : 'Mypart.xyz', // empty == document.element.!!
- order : '001',
- name : 'xxxx'
- region : 'xxxx'
- disabled : function() {}
-
- tree : function() { // return an tree of xtype declared components
- var MODULE = this;
- return
- {
- xtype : 'NestedLayoutPanel',
- // technicall
- }
- ]
- *})
- *
- *
- * It can be used to build a big heiracy, with parent etc.
- * or you can just use this to render a single compoent to a dom element
- * MYPART.render(Roo.Element | String(id) | dom_element )
- *
- *
- * Usage patterns.
- *
- * Classic Roo
- *
- * Roo is designed primarily as a single page application, so the UI build for a standard interface will
- * expect a single 'TOP' level module normally indicated by the 'parent' of the XComponent definition being defined as false.
- *
- * Each sub module is expected to have a parent pointing to the class name of it's parent module.
- *
- * When the top level is false, a 'Roo.BorderLayout' is created and the element is flagged as 'topModule'
- * - if mulitple topModules exist, the last one is defined as the top module.
- *
- * Embeded Roo
- *
- * When the top level or multiple modules are to embedded into a existing HTML page,
- * the parent element can container '#id' of the element where the module will be drawn.
- *
- * Bootstrap Roo
- *
- * Unlike classic Roo, the bootstrap tends not to be used as a single page.
- * it relies more on a include mechanism, where sub modules are included into an outer page.
- * This is normally managed by the builder tools using Roo.apply( options, Included.Sub.Module )
- *
- * Bootstrap Roo Included elements
- *
- * Our builder application needs the ability to preview these sub compoennts. They will normally have parent=false set,
- * hence confusing the component builder as it thinks there are multiple top level elements.
- *
- * String Over-ride & Translations
- *
- * Our builder application writes all the strings as _strings and _named_strings. This is to enable the translation of elements,
- * and also the 'overlaying of string values - needed when different versions of the same application with different text content
- * are needed. @see Roo.XComponent.overlayString
- *
- *
- *
- * @extends Roo.util.Observable
+ * @class Roo.Layer
+ * @extends Roo.Element
+ * An extended {@link Roo.Element} object that supports a shadow and shim, constrain to viewport and
+ * automatic maintaining of shadow/shim positions.
+ * @cfg {Boolean} shim False to disable the iframe shim in browsers which need one (defaults to true)
+ * @cfg {String/Boolean} shadow True to create a shadow element with default class "x-layer-shadow", or
+ * you can pass a string with a CSS class name. False turns off the shadow.
+ * @cfg {Object} dh DomHelper object config to create element with (defaults to {tag: "div", cls: "x-layer"}).
+ * @cfg {Boolean} constrain False to disable constrain to viewport (defaults to true)
+ * @cfg {String} cls CSS class to add to the element
+ * @cfg {Number} zindex Starting z-index (defaults to 11000)
+ * @cfg {Number} shadowOffset Number of pixels to offset the shadow (defaults to 3)
* @constructor
- * @param cfg {Object} configuration of component
- *
+ * @param {Object} config An object with config options.
+ * @param {String/HTMLElement} existingEl (optional) Uses an existing DOM element. If the element is not found it creates it.

+ * MYPART.render(Roo.Element | String(id) | dom_element )
+ *
+ *
+ * Usage patterns.
+ *
+ * Classic Roo
+ *
+ * Roo is designed primarily as a single page application, so the UI build for a standard interface will
+ * expect a single 'TOP' level module normally indicated by the 'parent' of the XComponent definition being defined as false.
+ *
+ * Each sub module is expected to have a parent pointing to the class name of it's parent module.
+ *
+ * When the top level is false, a 'Roo.BorderLayout' is created and the element is flagged as 'topModule'
+ * - if mulitple topModules exist, the last one is defined as the top module.
+ *
+ * Embeded Roo
+ *
+ * When the top level or multiple modules are to embedded into a existing HTML page,
+ * the parent element can container '#id' of the element where the module will be drawn.
+ *
+ * Bootstrap Roo
+ *
+ * Unlike classic Roo, the bootstrap tends not to be used as a single page.
+ * it relies more on a include mechanism, where sub modules are included into an outer page.
+ * This is normally managed by the builder tools using Roo.apply( options, Included.Sub.Module )
+ *
+ * Bootstrap Roo Included elements
+ *
+ * Our builder application needs the ability to preview these sub compoennts. They will normally have parent=false set,
+ * hence confusing the component builder as it thinks there are multiple top level elements.
+ *
+ * String Over-ride & Translations
+ *
+ * Our builder application writes all the strings as _strings and _named_strings. This is to enable the translation of elements,
+ * and also the 'overlaying of string values - needed when different versions of the same application with different text content
+ * are needed. @see Roo.XComponent.overlayString
+ *
+ *
+ *
+ * @extends Roo.util.Observable
+ * @constructor
+ * @param cfg {Object} configuration of component

- * @class Roo.dd.DragDrop
- * @extends Roo.util.Observable
- * Defines the interface and base operation of items that that can be
- * dragged or can be drop targets. It was designed to be extended, overriding
- * the event handlers for startDrag, onDrag, onDragOver and onDragOut.
- * Up to three html elements can be associated with a DragDrop instance:
- * <ul>
- * <li>linked element: the element that is passed into the constructor.
- * This is the element which defines the boundaries for interaction with
- * other DragDrop objects.</li>
- * <li>handle element(s): The drag operation only occurs if the element that
- * was clicked matches a handle element. By default this is the linked
- * element, but there are times that you will want only a portion of the
- * linked element to initiate the drag operation, and the setHandleElId()
- * method provides a way to define this.</li>
- * <li>drag element: this represents the element that would be moved along
- * with the cursor during a drag operation. By default, this is the linked
- * element itself as in {@link Roo.dd.DD}. setDragElId() lets you define
- * a separate element that would be moved, as in {@link Roo.dd.DDProxy}.
- * </li>
- * </ul>
- * This class should not be instantiated until the onload event to ensure that
- * the associated elements are available.
- * The following would define a DragDrop obj that would interact with any
- * other DragDrop obj in the "group1" group:
- * <pre>
- * dd = new Roo.dd.DragDrop("div1", "group1");
- * </pre>
- * Since none of the event handlers have been implemented, nothing would
- * actually happen if you were to run the code above. Normally you would
- * override this class or one of the default implementations, but you can
- * also override the methods you want on an instance of the class...
- * <pre>
- * dd.onDragDrop = function(e, id) {
- * alert("dd was dropped on " + id);
- * }
- * </pre>
- * @constructor
- * @param {String} id of the element that is linked to this instance
- * @param {String} sGroup the group of related DragDrop objects
- * @param {object} config an object containing configurable attributes
- * Valid properties for DragDrop:
- * padding, isTarget, maintainOffset, primaryButtonOnly

+ * Defines the interface and base operation of items that that can be

+ * Up to three html elements can be associated with a DragDrop instance:
+ * <ul>
+ * <li>linked element: the element that is passed into the constructor.
+ * This is the element which defines the boundaries for interaction with
+ * other DragDrop objects.</li>
+ * <li>handle element(s): The drag operation only occurs if the element that
+ * was clicked matches a handle element. By default this is the linked
+ * element, but there are times that you will want only a portion of the
+ * linked element to initiate the drag operation, and the setHandleElId()
+ * method provides a way to define this.</li>
+ * <li>drag element: this represents the element that would be moved along
+ * with the cursor during a drag operation. By default, this is the linked
+ * element itself as in {@link Roo.dd.DD}. setDragElId() lets you define
+ * a separate element that would be moved, as in {@link Roo.dd.DDProxy}.
+ * </li>
+ * </ul>
+ * This class should not be instantiated until the onload event to ensure that
+ * the associated elements are available.
+ * The following would define a DragDrop obj that would interact with any
+ * other DragDrop obj in the "group1" group:
+ * <pre>
+ * dd = new Roo.dd.DragDrop("div1", "group1");
+ * </pre>
+ * Since none of the event handlers have been implemented, nothing would
+ * actually happen if you were to run the code above. Normally you would
+ * override this class or one of the default implementations, but you can
+ * also override the methods you want on an instance of the class...
