Finding Strings, booleans and Integers

**Pez** · 07-19-2009, 09:26 AM

Hello,

I'm new to java (have been teaching myself for around 3 months) and at the moment i am trying to make a GUI using a subclass basically i need to return values to the main class for :
boolean useFood = false; // needs to be true (in the main class) when the tickbox is selected
static String foodType; // to be determined by a jtextfield (in the main class)
int withdrawAmmount // to be determined by a jtextfield (in the main class)

here is the code i have upto now, i couldnt find action listeners on jigloo but did find an abstract action not sure if thats the same thing for jigloo... any help would be much appreciated. Paul

here is the code

Java Code:

public class GUI extends javax.swing.JFrame {
	private JButton runButton;
	private JTextField foodName;
	private AbstractAction useFoodBoolean;
	private AbstractAction startAction;
	private JLabel withdrawLabel;
	private JTextField jTextField1;
	private JLabel FoodLabel;
	private JCheckBox useFood;

	/**
	* Auto-generated main method to display this JFrame
	*/
	public static void main(String[] args) {
		SwingUtilities.invokeLater(new Runnable() {
			public void run() {
				NewJFrame inst = new NewJFrame();
				inst.setLocationRelativeTo(null);
				inst.setVisible(true);
			}
		});
	}

	public GUI() {
		super();
		initGUI();
	}

	private void initGUI() {
		try {
			GroupLayout thisLayout = new GroupLayout((JComponent)getContentPane());
			getContentPane().setLayout(thisLayout);
			setDefaultCloseOperation(WindowConstants.DISPOSE_ON_CLOSE);
			{
				runButton = new JButton();
				runButton.setText("Start");
				runButton.setAction(getStartAction());
			}
			{
				foodName = new JTextField();
			}
			{
				useFood = new JCheckBox();
				useFood.setText("Use Food?");
				useFood.setAction(getUseFoodBoolean());
			}
			{
				FoodLabel = new JLabel();
				FoodLabel.setText("Food Name");
			}
			{
				jTextField1 = new JTextField();
			}
			{
				withdrawLabel = new JLabel();
				withdrawLabel.setText("withdraw X ?");
			}
			thisLayout.setVerticalGroup(thisLayout.createSequentialGroup()
