前面搞了这么久的基础，下面该来做这个界面了：
这是一个浮动窗口，可以在页面内到处拉动。

其中有两个地方需要再解释：
1、getEl（）的官方解释
Returns the Ext.Element which encapsulates this Component.
This will usually be a <DIV> element created by the class's onRender method, but that may be overridden using the autoEl config.
Note: this element will not be available until this Component has been rendered.
To add listeners for DOM events to this Component (as opposed to listeners for this Component's own Observable events), see the listeners config for a suggestion, or use a render listener directly:
new Ext.Panel({
title: 'The Clickable Panel',
listeners: {
render: function(p) {
// Append the Panel to the click handler's argument list.
p.getEl().on('click', handlePanelClick.createDelegate(null, [p], true));
},
single: true // Remove the listener after first invocation
}
});
Parameters:
None.
Returns:
Ext.Element
The Element which encapsulates this Component.
