user. They are computed by the layout manager from dimensions and locations of
the embedded components. The figure also shows the weights given to the columns
and rows. The first column gets weight 2

Figure 17.3 A sketch of the desired layout that reflects the column-row structure implicitly
used by the layout manager. The resulting 3 3 grid is shown by dashed lines. The weights

are shown at the top and left. The sums of the column and row weights are shown in
