    Default JTextField won't update

    I am fairly new to Java and am having issues getting a JTextField to update using setText.
    I can setText and then println, but it won't update in the GUI.

    The object, jTextFieldFirstName is declared within the constructor in class Panel. It uses a method in class AddressFields to obtain the String from an array.

    Any help would be greatly appreciated!

    Here is my code:
    Java Code:
    import java.awt.*;
    import java.awt.event.ActionEvent;
    import java.awt.event.ActionListener;
    
    import javax.swing.JButton;
    import javax.swing.JFrame;
    import javax.swing.JPanel;
    import javax.swing.JLabel;
    import javax.swing.JTextField;
    import javax.swing.SwingWorker;
    import javax.swing.WindowConstants;
    import javax.swing.GroupLayout;
    import javax.swing.LayoutStyle;
    import javax.swing.SwingWorker;
    
    public class Panel extends JFrame implements ActionListener 
    {
    	
    	// Initializes the variables
       	JFrame myJFrame;
       	JLabel jLabelAddressBook, jLabelFirstName, jLabelLastName, jLabelPhoneNumber, jLabelEmailAddress;
       	JLabel jLabelStreet, jLabelCityName, jLabelStateName, jLabelZipCode;
       	JPanel jPanel1, jPanel2;
       	public JTextField jTextFieldFirstName, jTextFieldLastName, jTextFieldPhoneNumber, jTextFieldEmailAddress, jTextFieldStreetNumber, jTextFieldStreetName;
       	public JTextField jTextFieldCityName, jTextFieldStateName, jTextFieldZipCode;
       	JButton jButtonSave, jButtonDelete, jButtonClear, jButtonUpdate, jButtonAdd,	jButtonForward, jButtonBack, jButtonExit;
       	String firstName, lastName, phoneNumber, emailAddress, streetNumber, streetName, cityName, stateName, zipCode;
       	int entryNumber;	
       	
       // Constructor	
       public Panel()
       { 	
                    ...
    
                    // Declares the JTextField objects
       		jTextFieldFirstName = new JTextField(10);
    
                    ...
        }   // End Constructor
    
       	public void displayCurrentEntry(AddressFields myAddressFields)  // myAddressFields object contains getters and setters
       	{
    		/* Trying to figure out why I can set 
    		 * and get the text, but it won't update 
    		 * in the display
    		 */
       		
       		jTextFieldFirstName.setText(myAddressFields.getFirstName(myAddressFields.getEntryNumber()));
    		jTextFieldLastName.setText(myAddressFields.getLastName(myAddressFields.getEntryNumber()));
       		jTextFieldPhoneNumber.setText(myAddressFields.getPhoneNumber(myAddressFields.getEntryNumber()));
       		jTextFieldEmailAddress.setText(myAddressFields.getEmailAddress(myAddressFields.getEntryNumber()));
       		jTextFieldStreetNumber.setText(myAddressFields.getStreetNumber(myAddressFields.getEntryNumber()));
       		jTextFieldStreetName.setText(myAddressFields.getStreetName(myAddressFields.getEntryNumber()));
       		jTextFieldCityName.setText(myAddressFields.getCityName(myAddressFields.getEntryNumber()));
       		jTextFieldStateName.setText(myAddressFields.getStateName(myAddressFields.getEntryNumber()));
       		jTextFieldZipCode.setText(myAddressFields.getZipCode(myAddressFields.getEntryNumber()));
       		
       		jPanel1.repaint();
       	}	// End displayEntry method
    }  // End Panel class

    Default Re: JTextField won't update

    It's a bit hard to tell from the snippet of code posted. A common mistake is to setText() on a component that is not the same as the one you added to the gui. For example by declaring another component using the same variable. Another is to set up a method like displayCurrentEntry() which never gets called: you can check that this method is called by adding a System.out.println() at the start.

    Consider writing a SSCCE that illustrates the problem. Ie, something compilable and runnable but with only a single JTextField showing the problem. I realise that this might involve stepping back from Netbeans.

    -----

    When you post code, use the "code" tags. Put [code] at the start of the code and [/code] at the end. That way the formatting will be preserved. It's also a good idea to indent with spaces rather than tabs as the latter tend to get rendered rather generously by web browsers.

    Default Re: JTextField won't update

    Thanks for heads up about the Code tags. I'm new to this forum so I wasn't aware.

    I actually only used NetBeans to build the GroupLayout. I wrote the rest of the code myself in
    Eclipse.
    It is calling the correct object. Because if I println, using getText, it gives me the correct String.

    Again to repeat what Peter stated, given what you've posted so far, we can't guess why it's not working. You'll either have to do some more debugging yourself or post more code -- best an SSCCE (again as suggested above).

    Also I fear that you're misinterpreting the results you're getting. All the println statement is telling you is that you're filling in the JTextField of some Panel object. It doesn't tell you that you're doing this for the Panel object that is currently being displayed which is what I am guessing is wrong (again, all we can do is guess at this point in time til you tell/show more).

    I don't have time to do an SSCCE today, but I will tomorrow.

    However, here's the full class code. I've also attached all classes in a zip file.


    Java Code:

     * two panels, one for the text fields and one

    Default Re: JTextField won't update

    I might be wrong as that GroupLayout stuff is hard to follow, but it looks like you're sticking all the text widgets into the contentPane and not jPanel1.
    Your redraw is called on jPanel1?
    jPanel1 is never added to the frame (and does not hold those fields).
