/**
- * @class Ext.ComponentQuery
- * @extends Object
- *
* Provides searching of Components within Ext.ComponentManager (globally) or a specific
* Ext.container.Container on the document with a similar syntax to a CSS selector.
*
* Components can be retrieved by using their {@link Ext.Component xtype} with an optional . prefix
-<ul>
- <li>component or .component</li>
- <li>gridpanel or .gridpanel</li>
-</ul>
+ *
+ * - `component` or `.component`
+ * - `gridpanel` or `.gridpanel`
*
* An itemId or id must be prefixed with a #
-<ul>
- <li>#myContainer</li>
-</ul>
*
+ * - `#myContainer`
*
* Attributes must be wrapped in brackets
-<ul>
- <li>component[autoScroll]</li>
- <li>panel[title="Test"]</li>
-</ul>
*
- * Member expressions from candidate Components may be tested. If the expression returns a <i>truthy</i> value,
- * the candidate Component will be included in the query:<pre><code>
-var disabledFields = myFormPanel.query("{isDisabled()}");
-</code></pre>
+ * - `component[autoScroll]`
+ * - `panel[title="Test"]`
+ *
+ * Member expressions from candidate Components may be tested. If the expression returns a *truthy* value,
+ * the candidate Component will be included in the query:
+ *
+ * var disabledFields = myFormPanel.query("{isDisabled()}");
+ *
+ * Pseudo classes may be used to filter results in the same way as in {@link Ext.DomQuery DomQuery}:
+ *
+ * // Function receives array and returns a filtered array.
+ * Ext.ComponentQuery.pseudos.invalid = function(items) {
+ * var i = 0, l = items.length, c, result = [];
+ * for (; i < l; i++) {
+ * if (!(c = items[i]).isValid()) {
+ * result.push(c);
+ * }
+ * }
+ * return result;
+ * };
+ *
+ * var invalidFields = myFormPanel.query('field:invalid');
+ * if (invalidFields.length) {
+ * invalidFields[0].getEl().scrollIntoView(myFormPanel.body);
+ * for (var i = 0, l = invalidFields.length; i < l; i++) {
+ * invalidFields[i].getEl().frame("red");
+ * }
