Method Detail

render

void render(java.lang.Object row,
            int rowIndex,
            int columnIndex,
            TableView tableView,
            java.lang.String columnName,

            boolean highlighted,
            boolean disabled)

columnIndex - The index of the column being rendered.

tableView - The host component.

columnName - The name of the column being rendered.

selected - If true, the row is selected.

highlighted - If true, the row is highlighted.

disabled - If true, the row is disabled.

toString

java.lang.String toString(java.lang.Object row,
                          java.lang.String columnName)

Converts table view cell data to a string representation.

Parameters:

row - The row object.

columnName - The name of the column.

Returns:

The cell data's string representation, or null if the data does not have a string representation.

Note that this method may be called often during keyboard navigation, so implementations should avoid unnecessary string allocations.
