Sorting a CellTable server-side

Question

I\'m currently using a Gwt CellTable, bound to my GAE/Objectify backend via RPC calls.

All right now! :-)

Then I want to sort columns, so I read http://code.goog

Answer 1

I have used something like this as an application column object.

public class ScrollTableColumn {

    // --------------------------------------------------------------- Field(s)

    private int            sequence;
    private Column         column;
    private Header         header;
    private int            size;
    private int            calculatedSize;
    private boolean        show;
    private PartialColumn  partialColumn;
    private ColumnNameEnum columnName;

}

Now create a HashMap of the above as follows:

Map columnMap 
    = new HashMap();

Add all the columns as you create them both in the ScrollTableColumn and in the columnMap.

Finally you can get the required name as:

ColumnSortList sortList = dataTable.getColumnSortList();
Column column = sortList.get(0).getColumn();
ColumnNameEnum = columnMap.get(column);
String name = ColumnNameEnum.getName();
