With the constraints for the buttons as before, the window looks as shown in Figure 17-32 .
FIGURE 17-32
Both the Push and the Press button occupy the same space in the container, but because fill is set to
NONE they are not expanded to fill the space in either direction. The ipadx and ipady constraints specify
by how much the buttons are to be expanded from their preferred size — by 30 pixels on the left and
right and 10 pixels on the top and bottom. The overall arrangement remains the same.
