Ext.MessageBox.confirm自定义按钮

是否可以向Ext.MessageBox.confirm添加自定义按钮.按照自定义我的意思是自定义文本和自定义按钮数...

Ext.MessageBox.confirm('Delete', 'Are you sure ?', 

function(btn){
   if(btn === 'yes'){
      return true;
   }
   else{
      return false;
   }
 });

尝试设置buttonText,如:

Ext.MessageBox.show({
        title: 'Delete',
        message: 'Are you sure ?',
        width: 300,
        buttons: Ext.Msg.YESNO,
        buttonText: {
            yes: 'Yesssss!!!',
            no: 'Nooo!!!'
        }
    });
