Constructor Detail

ColumnLayout

public ColumnLayout(int columns,
                    int cellexpn,
                    int cellpos,
                    int rubbercolumn,
                    int rubberrow)

Creates a column layout with default insets

Parameters:

columns - the number of columns

cellexpn - expand the component within cell (NONE, ALL, HORZ, VERT)

cellpos - position of component within cell (NW, N, NE, E, SE, S, SW, W, C)

rubbercolumn - specify column to expand if parent larger as needed (NONE, ALL, )

rubberrow - specify row to expand if parent larger as needed (NONE, ALL, )
