/**
+ * @class Ext.window.Window
+ * @extends Ext.panel.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.
- * 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.
- * By default, Windows will be rendered to document.body. To {@link #constrain} a Window to another element
- * specify {@link Ext.Component#renderTo renderTo}.
- * Note: By default, the {@link #closable close} header tool destroys the Window resulting in
- * destruction of any child Components. This makes the Window object, and all its descendants unusable. To enable
- * re-use of a Window, use {@link #closeAction closeAction: 'hide'}.
+ * restored to their prior size, and can be {@link #minimize}d.</p>
+ * <p>Windows can also be linked to a {@link Ext.ZIndexManager} or managed by the {@link Ext.WindowManager} 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>As with all {@link Ext.container.Container Container}s, it is important to consider how you want the Window
+ * to size and arrange any child Components. Choose an appropriate {@link #layout} configuration which lays out
+ * child Components in the required manner.</b></p>
