// Create left column of radio buttons
Box left = Box.createVerticalBox();
ButtonGroup radioGroup = new ButtonGroup(); // Create button group
JRadioButton rbutton; // Stores a button
radioGroup.add(rbutton = new JRadioButton("Red")); // Add to group
left.add(rbutton); // Add to Box
radioGroup.add(rbutton = new JRadioButton("Green"));
left.add(rbutton);
radioGroup.add(rbutton = new JRadioButton("Blue"));
left.add(rbutton);
radioGroup.add(rbutton = new JRadioButton("Yellow"));
left.add(rbutton);
// Create right columns of checkboxes
Box right = Box.createVerticalBox();
right.add(new JCheckBox("Dashed"));
right.add(new JCheckBox("Thick"));
right.add(new JCheckBox("Rounded"));
// Create top row to hold left and right
Box top = Box.createHorizontalBox();
top.add(left);
top.add(right);
// Create bottom row of buttons
JPanel bottomPanel = new JPanel();
Border edge = BorderFactory.createRaisedBevelBorder(); // Button border
JButton button;
Dimension size = new Dimension(80,20);
bottomPanel.add(button = new JButton("Defaults"));
button.setBorder(edge);
button.setPreferredSize(size);
bottomPanel.add(button = new JButton("OK"));
button.setBorder(edge);
button.setPreferredSize(size);
bottomPanel.add(button = new JButton("Cancel"));
button.setBorder(edge);
button.setPreferredSize(size);
// Add top and bottom panel to content pane
Container content = aWindow.getContentPane(); // Get content pane
content.setLayout(new BorderLayout()); // Set border layout manager
content.add(top, BorderLayout.CENTER);
content.add(bottomPanel, BorderLayout.SOUTH);
aWindow.setVisible(true); // Display the window
}
}
When you run this example and try out the radio buttons and checkboxes, it should produce a window
something like that shown overleaf.
