have idea?

you can use ext.componentquery.query find toolbar.

using xtype toolbar,it return array of objects.

 ext.componentquery.query('toolbar')[0]; 

if have more on toolbars,you can give unique itemid toolbar in config itemid:'buttontoolbar'.

 ext.componentquery.query('#buttontoolbar')[0]; 

similarly give unique name toolbar in config name:'buttontoolbar'.

ext.componentquery.query('toolbar[name=buttontoolbar]')[0];
