附上 HtmlEditor的添加示例：

var editor = 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
