EXT 关于控件焦点问题

1：某个控件获取焦点：

wxerp.baseinfo.cashaccount.viewwindow.superclass.constructor.call(this, { id: wxerp.baseinfo.cashaccount.constants.this_window_view_id, buttonAlign: 'center', autoHeight: true, width:350, resizable:false, plain:true, modal:true, autoScroll:true, buttons:[ { text:common_button_close_text, iconCls: button_close_class, handler:this.destroy, scope:this } ], defaultButton: 0, items: [this.viewCashAccountForm] });
