FIGURE 11.3
Nine buttons
arranged in a 3

grid layout.
One thing to note about the buttons in Figure 11.3 is that they expanded to fill the space
available to them in each cell. This is an important difference between grid layout and
some of the other layout managers, which display components at a much smaller size.
