Hi All,
i trying to create base controller - for visual inheritance with events.
What was done:
Ext.define('Default.Window', extend:'Ext.Window'.....
with toolbar and tabpanel for two items (by xtype)
Ext.define('Default.Form'........
Ext.define('Default.Grid'........

What stops me:
how to define in base controller : (for example) button for change tabpanel active item grid<>form...for inheritance?
Ext.define('My.Form' extends : 'Default.Form'......
Ext.define('My.Grid' extends : 'Default.Grid'......
Ext.define('My.Window', extends : 'Default.Window' // with tollbar and tabpanel:items{grid,form}

How in
Ext.define('Default.Controller'......
create events (components dependencies) and make them available (work) in
Ext.define('My.Controller', extends : 'Default.Controller'
?

is it possible to perform?
