I'm trying to build a GUI which has submenus and may return to main menu and options, so far I've created a main menu but when I try to click the boxes nothing opens also only 4 items are showing when I have coded 5 items. Does anyone know a way around this? Also If anyone knows how to create different boxes not check boxes. Many thanks
public class CoinSorterGUI {
public static void main(String[] args) {
final JFrame frame=new JFrame("CoinSorterGUI");
class MyItemListener implements ItemListener{
public void itemStateChanged(ItemEvent ev) {
boolean selected = (ev.getStateChange()== ItemEvent.SELECTED);
AbstractButton button =(AbstractButton) ev.getItemSelectable();
String command = button.getActionCommand();
if (selected) {
int messageType = -1;
String message = "";
if (command.equals("CoinCalculator")) {
messageType = JOptionPane.INFORMATION_MESSAGE;
message = "Welcome to the CoinCalculator";
}else if (command.equals("Multiple CoinCalculator")) {
messageType = JOptionPane.INFORMATION_MESSAGE;
message = "Welcome to the Multiple CoinCalculator";
}else if (command.equals("Print Coin List")) {
messageType = JOptionPane.INFORMATION_MESSAGE;
message = "Current coin denominations are; £2, £1, 50p. 20p and 10p";
}else if (command.equals("Set details")) {
messageType = JOptionPane.INFORMATION_MESSAGE;
message = " ** Set details Sub Menu ** "
+ " 1 - Set Currency "
+ " 2 - Set minimum input value"
+ " 3 - Set Maximum input value"
+ " 4 - Return to main menu";
}else if (command.equals("Display program configuarations")) {
messageType = JOptionPane.INFORMATION_MESSAGE;
message = "The current currency is £, the minimum input value is 0 and the maximum input value is 10000";
}
JOptionPane.showMessageDialog(frame,
message,
"CoinSorter",
messageType);
}
}
}
JRadioButton r1 = new JRadioButton("CoinCalculator");
r1.setActionCommand("Welcome to the CoinCalculator");
JRadioButton r2 = new JRadioButton("Multiple CoinCalculator");
r2.setActionCommand("Welcome to the Multiple CoinCalculator");
JRadioButton r3 = new JRadioButton("Print Coin List");
r3.setActionCommand("Current coin denominations are; £2, £1, 50p. 20p and 10p");
JRadioButton r4 = new JRadioButton("Set details");
r4.setActionCommand(" ** Set details Sub Menu ** "
+ " 1 - Set Currency "
+ " 2 - Set minimum input value"
+ " 3 - Set Maximum input value"
+ " 4 - Return to main menu");
JRadioButton r5 = new JRadioButton("Display program configuarations");
r5.setActionCommand("The current currency is £, the minimum input value is 0 and the maximum input value is 10000");
final ButtonGroup group = new ButtonGroup();
group.add(r1);
group.add(r2);
group.add(r3);
group.add(r4);
group.add(r5);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(300, 200);
Container cont = frame.getContentPane();
cont.setLayout(new GridLayout(0, 1));
cont.add(new JLabel("Please choose from the options: "));
cont.add(r1);
cont.add(r2);
cont.add(r3);
cont.add(r4);
frame.setVisible(true);
}
}
only 4 items are showing when I have coded 5 items
cont.add(r4);
frame.setVisible(true);
Should be:
cont.add(r4);
cont.add(r5); // add ALL the buttons!
frame.setVisible(true);
