DB_DataObject and Structures_DataGrid integration

Hi, I want to bind Structures_DataGrid to DB_DataObject in a more integrated manner than Structures_DataGrid_Record_DataObject. My constatation is : - DataObject can sort and limit the data - Datagrid knows how the user wants her data sorted and limited Given that, I believe DataGrid and DataObject can interact in a bilateral way : - DataObject providing data to DataGrid (which DataGrid_Record_DataObject implements for a single record) - DataGrid telling DataObject what data to retrieve according to the user wish. While implementing this for my own needs, I may turn it into reusable code. How do you think I should go : - improving DataGrid_Record_DataObject ? - creating DB_DataObject_DataGrid (my current favourite) ? - creating a driver for DB_DataObject_FormBuilder ("FormBuilder_DataGrid") ? - something else ? -- og
