Thread: Combo/TextField Help

Hi, I've created a Swing program that uses content pane to display components. I have two problems - My zipCombo is supposed to be editable but it isn't and I need to know how to align my TextFields so they're even (at runtime). Any help would be greatly appreciated.

 
public class PersonalData extends JFrame implements ActionListener
{
	        //Initialize Array
	        String zipCode[] = {"38001", "38006", "38343", "38305", "38301"};
	        String states[] = {"AL", "AK","AZ","AR","CA","CO","CT","DE","FL","GA","GU","HI","ID","IL","IN","IA","KS","KY","LA","MA","MD","MS","MI","MN","MI","MO","MT","NE","NV","NH","NJ","NM","NY","NC","ND","OH","OK","OR","PA","PR","RI","SC","SD","TN","TX","UT","VT","VI","VA","WA","WV","WI","WY"};
 
 
	                     //Construct a panel for each row
	        	JPanel firstRow = new JPanel();
	        	JPanel secondRow = new JPanel();
	        	JPanel thirdRow = new JPanel();
	        	JPanel fourthRow = new JPanel();
	        	JPanel fifthRow = new JPanel();
	        	JPanel sixthRow = new JPanel();
 
	        	//Construct Components
		JComboBox zipCombo = new JComboBox(zipCode);
		JComboBox stateCombo = new JComboBox(states);
 
	        	//Construct a panel for the fields and buttons
	        	JPanel fieldPanel = new JPanel();
 
	        	//Construct labels and text boxes
	        	JLabel firstNameLabel = new JLabel("First Name:");
	            	     JTextField firstName = new JTextField(20);
	        	JLabel lastNameLabel = new JLabel("Last Name:");
	            	     JTextField lastName= new JTextField(20);
	        	JLabel addressLabel = new JLabel("Address:");
	                          JTextField address = new JTextField(30);
	        	JLabel cityLabel = new JLabel("City:");
	            	     JTextField city = new JTextField(10);
	        	JLabel stateLabel = new JLabel("State:");
	            	     JTextField state = new JTextField(2);
	        	JLabel zipLabel = new JLabel("Zip:");
	            	     JTextField zip = new JTextField(9);
 
 
	        	//Construct Button
	        	JButton submitButton = new JButton("Submit");
 
	    	//Create Content Pane
	   	public void createContentPane()
	   	{
	    	        //Populate the JComboBox
	       	        stateCombo.addActionListener(this);
	       	        zipCombo.addActionListener(this);
	        	        [B]zipCombo.setEditable(true);[/B]
		}
 
		public static void main(String args[])
	        	{
	            	     PersonalData f= new PersonalData();

	                	          fieldPanel.setLayout(new GridLayout(8,1));

	                	     firstRow.add(firstNameLabel);

		     fourthRow.add(cityLabel);
		     fourthRow.add(city);
		     fourthRow.add(stateLabel);
		     fourthRow.add(stateCombo);
		     fourthRow.add(zipLabel);
	                          fourthRow.add(zipCombo);
 
	                	     fifthRow.add(submitButton);
 
	                	      //Add rows to panel
	                	      fieldPanel.add(firstRow);
	                	      fieldPanel.add(secondRow);
	                	      fieldPanel.add(thirdRow);

		     //Add panels to frame
	                	     c.add(fieldPanel, BorderLayout.CENTER);
 
 
	                	      //Add functionality to button
	        	      submitButton.addActionListener(this);
	    	}
 
	    	   public void actionPerformed(ActionEvent e)
	    	   {
	        	         //user clicks the combo box
	        	         if (e.getSource() == stateCombo);
 
	        	         if (e.getSource() == zipCombo);
	    	   }
}

That helped. Thanks!! :-)
