This example illustrates the use of the GridRows objects to create the rows of a grid. This example is makes the same GUI as Example10, but a little bit less verbose, due to the use of GridRows. This example creates the GUI proposed as a challenge problem for layout managers. Note that the use of the GridRows class makes the construction of the grid much easier than the other possibilities that entail the use of one of the other (createCellGrid(Cell[][] cellArray) and createCellGrid(Component[][] cellArray)) methods for creation of a grid.
