- * @class Ext.Window
- * @extends Ext.Panel
- * <p>A specialized panel intended for use as an application window. Windows are floated, {@link #resizable}, and
- * {@link #draggable} by default. Windows can be {@link #maximizable maximized} to fill the viewport,
- * restored to their prior size, and can be {@link #minimize}d.</p>
- * <p>Windows can also be linked to a {@link Ext.WindowGroup} or managed by the {@link Ext.WindowMgr} to provide
- * grouping, activation, to front, to back and other application-specific behavior.</p>
- * <p>By default, Windows will be rendered to document.body. To {@link #constrain} a Window to another element
- * specify {@link Ext.Component#renderTo renderTo}.</p>
- * <p><b>Note:</b> By default, the <code>{@link #closable close}</code> header tool <i>destroys</i> the Window resulting in
- * destruction of any child Components. This makes the Window object, and all its descendants <b>unusable</b>. To enable
- * re-use of a Window, use <b><code>{@link #closeAction closeAction: 'hide'}</code></b>.</p>
- * @constructor
- * @param {Object} config The config object
