With these code changes, the window is as shown in Figure 17-31 .

You could also see the effect of padding the components out from their preferred size by altering the but-
ton constraints a little:

// Set constraints and add first button
constraints.weightx = constraints.weighty = 10.0;
constraints.fill = GridBagConstraints.NONE;
constraints.ipadx = 30; // Pad 30 in x
constraints.ipady = 10; // Pad 10 in y
addButton("Press", constraints, gridbag, aWindow); // Add button to
content pane

// Set constraints and add second button
constraints.weightx = 5.0; // Weight half of
first
constraints.fill = GridBagConstraints.BOTH; // Expand to fill

space
constraints.ipadx = constraints.ipady = 0; // No padding
constraints.insets = new Insets(10, 30, 10, 20); // Left 30 &
