Method Detail

calculateColumnWidths

public static DataRow calculateColumnWidths(ResultSet rs,
                                            float fontSize,
                                            boolean calculateAllRows,
                                            boolean useLabel)

Calculates the column widths

Parameters:

rs - the result set which contains representative data rows

fontSize - the font size that is used to calculate the column width

calculateAllRows - indicator if the perfect column width should be calculated for all rows in the result set

useLabel - indicates if the label instead of the field name should be used

Returns:

returns a data row which contains the width for each column (data field)
