+/**
+ * @class Ext.form.field.HtmlEditor
+ * @extends Ext.Component
+ *
+ * Provides a lightweight HTML Editor component. Some toolbar features are not supported by Safari and will be
+ * automatically hidden when needed. These are noted in the config options where appropriate.
+ *
+ * The editor's toolbar buttons have tooltips defined in the {@link #buttonTips} property, but they are not
+ * enabled by default unless the global {@link Ext.tip.QuickTipManager} singleton is {@link Ext.tip.QuickTipManager#init initialized}.
+ *
+ * An Editor is a sensitive component that can't be used in all spots standard fields can be used. Putting an Editor within
+ * any element that has display set to 'none' can cause problems in Safari and Firefox due to their default iframe reloading bugs.
+ *
+ * {@img Ext.form.HtmlEditor/Ext.form.HtmlEditor1.png Ext.form.HtmlEditor component}
+ *
+ * ## Example usage
+ *
+ * {@img Ext.form.HtmlEditor/Ext.form.HtmlEditor2.png Ext.form.HtmlEditor component}
+ *
+ * // Simple example rendered with default options:
+ * Ext.tip.QuickTips.init(); // enable tooltips
+ * Ext.create('Ext.form.HtmlEditor', {
+ * width: 580,
+ * height: 250,
+ * renderTo: Ext.getBody()
+ * });
+ *
+ * {@img Ext.form.HtmlEditor/Ext.form.HtmlEditor2.png Ext.form.HtmlEditor component}
+ *
+ * // Passed via xtype into a container and with custom options:
+ * Ext.tip.QuickTips.init(); // enable tooltips
+ * new Ext.panel.Panel({
+ * title: 'HTML Editor',
+ * renderTo: Ext.getBody(),
+ * width: 550,
+ * height: 250,
+ * frame: true,
+ * layout: 'fit',
+ * items: {
+ * xtype: 'htmleditor',
+ * enableColors: false,
+ * enableAlignments: false
+ * }
+ * });
+ *
+ * @constructor
+ * Create a new HtmlEditor
+ * @param {Object} config
+ * @xtype htmleditor
