this allows you to add buttons at the bottom of your gridpanel all other button properties are allowed to use. sample code is here: bbar: [ { xtype: 'button', text: 'Button 1' }, { xtype: 'button', text: 'Button 2' } ]
It is used in the VBox and HBox layouts: This configuration option is to be applied to child items of the container managed by this layout. Each child item with a flex property will be flexed horizontally according to each item's relative flex value compared to the sum of all items with a flex value specified.
