/**
* A specialized panel intended for use as an application window. Windows are floated, {@link #resizable}, and
* {@link #cfg-draggable} by default. Windows can be {@link #maximizable maximized} to fill the viewport, restored to
* their prior size, and can be {@link #method-minimize}d.
*
* 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.
*
* By default, Windows will be rendered to document.body. To {@link #constrain} a Window to another element specify
* {@link Ext.Component#renderTo renderTo}.
*
* **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.**
*
* @example
* Ext.create('Ext.window.Window', {
* title: 'Hello',
* height: 200,
* width: 400,
* layout: 'fit',
* items: { // Let's put an empty grid in just to illustrate fit layout
* xtype: 'grid',
* border: false,
* columns: [{header: 'World'}], // One header just for show. There's no data,
* store: Ext.create('Ext.data.ArrayStore', {}) // A dummy empty data store
* }
* }).show();
