+/**
+ * @class Ext.Editor
+ * @extends Ext.Component
+ *
+ * <p>
+ * The Editor class is used to provide inline editing for elements on the page. The editor
+ * is backed by a {@link Ext.form.field.Field} that will be displayed to edit the underlying content.
+ * The editor is a floating Component, when the editor is shown it is automatically aligned to
+ * display over the top of the bound element it is editing. The Editor contains several options
+ * for how to handle key presses:
+ * <ul>
+ * <li>{@link #completeOnEnter}</li>
+ * <li>{@link #cancelOnEsc}</li>
+ * <li>{@link #swallowKeys}</li>
+ * </ul>
+ * It also has options for how to use the value once the editor has been activated:
+ * <ul>
+ * <li>{@link #revertInvalid}</li>
+ * <li>{@link #ignoreNoChange}</li>
+ * <li>{@link #updateEl}</li>
+ * </ul>
+ * Sample usage:
+ * </p>
+ * <pre><code>
+var editor = new Ext.Editor({
+ updateEl: true, // update the innerHTML of the bound element when editing completes
+ field: {
+ xtype: 'textfield'
+ }
+});
+var el = Ext.get('my-text'); // The element to 'edit'
+editor.startEdit(el); // The value of the field will be taken as the innerHTML of the element.
+ * </code></pre>
+ * {@img Ext.Editor/Ext.Editor.png Ext.Editor component}
+ *
+ * @constructor
+ * Create a new Editor
+ * @param {Object} config The config object
+ * @xtype editor
