Ext JS, change grid column configs default values globally

Ext.grid.column.Column class has following configs:

• draggable (Defaults to: true)
• sortable (Defaults to: true)
• menuDisabled (Defaults to: false)

Is it possible to change default values of this configs globally for all grid columns in my application ?

Any help appreciated.

yes, using Ext.override......

http://docs.sencha.com/extjs/5.1/5.1.0-apidocs/#!/api/Ext-method-override

example...

Ext.override(Ext.grid.column.Column, {
 draggable: true,
 sortable: true,
 menuDisabled: false
});
