:: Reference :: Groups ::

Column and row groups are used to specifiy that a set of columns or rows will get the same width or height. This is an essential feature to implement symmetric, and more generally, balanced design.

Example

In the following example it is ensured that columns 2 and 4 get the same width, rows 1 and 4 get the same height as well as rows 2 and 3:

FormLayout layout = new FormLayout("p, d, p, d", "p, p, p, p");       
layout.setColumnGroups(new int[][]{ {2, 4} });
layout.setRowGroups   (new int[][]{ {1, 4}, {2, 3} });
