Creating grid from a type

[ljmoleiro]

Hi, i want to create a full grid from a type, to clean my controller code, and my entity class code, so i want to do all related to datagrid in a ExampleDatagridType php class, like this example https://github.com/APY/APYDataGridBundle/blob/master/Resources/doc/grid.md#creating-a-grid-from-a-type.
But I don't know how to set filters, action columns, etc, in the Type class.
