  com.arsdigita.toolbox.ui.DataTable.GlobalizedHeaderCellRenderer

All Implemented Interfaces:

TableCellRenderer

Enclosing class:

DataTable

protected static class DataTable.GlobalizedHeaderCellRenderer

extends Object

Always renders the table header as a link. Thus, it becomes possible to sort up and down by clicking the table column over and over.

Also, globalizes the column labels if possible.

getComponent

public Component getComponent(Table table,
                              PageState state,
                              Object value,

                              int column)

Description copied from interface: TableCellRenderer

Return a component with the visual representation for the passed in key and value.

The table sets the control event prior to calling this method, so that any control link returned as the component will, when clicked, cause the table to fire a TableActionEvent whose getRowKey() and getColumn() return the values of key and column. A simple cell renderer that achieves this would implement this method in the following way:

   public Component getComponent(Table table, PageState state, Object value,
              boolean isSelected, Object key,
              int row, int column) {
     return new ControlLink(value.toString());
   }
 

The column refers to a column in the table's TableColumnModel, i.e. the visual column on the screen, and not the table's representation of the underlying data in the TableModel.

Specified by:

getComponent in interface TableCellRenderer

Parameters:

table - the table requesting the rendering.

state - represents the state of the current request.

value - the data element to render as returned by the table model's getElementAt(column).

isSelected - true if this item is selected.

key - the key identifying this row (and possibly column) as returned by the table model's getKeyAt(column)

row - the number of the row in the table, the first row has number 0.

column - the number of the table column.

Returns:

the component that should be used to render the value.
