附上 HtmlEditor的添加示例：
vareditor = new Ext.form.HtmlEditor({
//内容略
});
editor.getToolbar().add('-', {
tooltip : '选择表情',
iconCls : 'temote',
menu : new Ext.menu.EmoteMenu({
allowReselect : true,
focus : Ext.emptyFn,
plain : true,
selectHandler : function(cm, emote) {
var emimg = "<img src='images/emote/emote_"
+ emote + ".gif' />";
editor.insertAtCursor(emimg);
},
scope : this,
clickEvent : 'mousedown'
})
})；
此代码不全，请在form 或者 win 被show 或者 render的时候 添加此内容
