主要代码:

Ext.onReady(function () {
    Ext.override(Ext.TabPanel, {
        initEvents: function () {
            Ext.TabPanel.superclass.initEvents.call(this);
            this.on('add', this.onAdd, this, {
                target: this
            });
            this.on('remove', this.onRemove, this, {
                target: this
            });
            this.mon(this.strip, 'mousedown', this.onStripMouseDown, this);
            this.mon(this.strip, 'contextmenu', this.onStripContextMenu, this);
            if (this.enableTabScroll) {
                this.mon(this.strip, 'mousewheel', this.onWheel, this);
            }
            //ADD:monitor title dbclick   
            this.mon(this.strip, 'dblclick', this.onTitleDblClick, this);
        }
    });
