public static void layoutToGrid(Container parent,
                                int numRow,
                                int numColumn,
                                int weightedRow,
                                int weightedColumn)

Parameters:

parent -

rowWeights -

columnWeights -

layoutToGrid

public static void layoutToGrid(Container parent,
                                List<Double> rowWeights,
                                List<Double> columnWeights)

Parameters:
