Help with JTextField

Hi all,
If I have the text content is longer than the JTextField, by default, it show me the last part of the text content on the JTextField. How can I make it to show the left (first) part of the content. Thanks for you help.

I forgot the code:

    }the only problem now is about how it should display the right info about the person whenever i click its name on the list.. something about file reading or something, i just cant figure it out.
    and also about how to make it scroll once it exceeds the list.. i cant make it work, maybe something about wrong declaration..
    thanks in advance..
    Edited by: syder on Mar 14, 2008 2:26 AM

    Like said before, do one thing at a time. At startup, something like:
    //put all the content in a list
    ArrayList<String> lines = new ArrayList<String>();
    while(String line=rand.readLine()!=null) {
        lines.add(line);
    }If you follow the good advice to create a class to encapsulate the entries, you could populate a list of such entries like this:
    static final int ENTRY_SIZE = 3;//you have 3 fields now, better to have a constant if that changes
    ArrayList<Entry> entries = new ArrayList<Entry>();
    for(int i=0; i<lines.size(); i+=ENTRY_SIZE) {
        Entry entry = new Entry(lines.get(i), lines.get(i+1), lines.get(i+2);
        entries.add(newEntry);
    }You could also do both of the above in one run, but I think you will understand better what's happening if you do one thing at a time.
    If you don't want to put the entries in an encapsulating class, you can still access this without looping:
    int listStartIdx = <desired_entry_index>*ENTRY_SIZE;
    String att1 = lines.get(listStartIdx).substring(1);
    String att2 = lines.get(listStartIdx+1).substring(1);
    String att3 = lines.get(listStartIdx+2).substring(1);

  • Need Help with a getText method

    Gday all,
    I need help with a getText method, i need to extract text from a JTextField. Although this text then needs to converted to a double so that i can multiply a number that i have already specified. As you may of guessed that the text i need to extract already will be in a double format.e.g 0.1 or 0.0000004 etc
    Thanks for your help
    ps heres what i have already done its not very good though
    ToBeConverted.getText();
    ( need help here)
    double amount = (and here)
    total = (amount*.621371192);
    Converted.setText("= " + total);

    Double.parseDouble( textField.getText() );

  • Need Help With D&D Program

    Hi, I'm not sure if I'm allowed to post questions on this forum but I can't find anywhere to talk to helpful people about programming.
    I'm making a dnd interface for JComponents. So far I've made a simple program that has a Component that can be lifted from a container and braught to the glass pane then later moved to anywhere on the screen and dropped into the container below it. Here's where my problems come:
    1) Rite now my 'Movable Component' is a JPanel which is just colored in. I want to either take a Graphic2d from a JComponent/Component and draw it on the JPanel or change the JPanel to the component I want to paint and disable the component.
    The problem with getting the Graphics2d is that if the component isn't on the screen it doesn't make a graphic object. I tried messing with the ui delicate and overriding parental methods for paintComponent, repaint, and that repaintChildren(forget name) but I haven't had luck getting a good graphics object. I was thinking of, at the beginning of running the program, putting 1 of each component onto the screen for a second then removing it but I'd rather not. I'd also like to change the graphics dynamicly if someone stretches the component there dropping and what not.
    The problem with disabling is that it changes some of the visual features of Components. I want to be able to update the Component myself to change how it looks and I don't want disabling to gray out components.
    I mainly just dont want the components to do any of there normal fuctions. This is for a page builder, by the way.
    Another problem I'm having is that mouseMotionListener is allowing me to select 2 components that are on top of one another when there edges are near each other. I don't know if theres a fix to this other than changing the Java Class.
    My next problem is a drop layout manager, but I'm doing pretty good with that rite now. It'll problem just move components out of the way of the falling component.
    One last thing I need help with is that I don't want the object that's being carried to go across the menu bar and certain areas. When I'm having the object being carried I have it braught up to the glass pane which allows it to move anywhere. Does anyone have any idea how I could prevent the component from being over the menu bars and other objects? I might have to make 1 panel is the movable area that can then be broken down into the 'component bank', 'building page' and whatever else I'm gonna need.
    This is all just test code to get together for when I make the real program but I need to make sure it'll be possible without a lot of hacking of code.
    Sorry for the length. Thanks for any help you can give.

    The trick to making viewable components that have no behaviour, is to render them onto an image of some sort (eg a BufferedImage). You can then display the Image on a JLabel that can be dragged around the desktop.
    Here is a piece of code that does the component rendering for you. This particular example uses a fixed component size, but you can modify that as you choose of course...public class JComponentImage
         private static GraphicsConfiguration gConfig;
         private static Dimension compSize = new Dimension(80, 22);
         private static Image image = null;
         public static Image getImage(Class objectClass)
              if (gConfig == null)
                   GraphicsEnvironment gEnv = GraphicsEnvironment.getLocalGraphicsEnvironment();
                   GraphicsDevice gDevice = gEnv.getDefaultScreenDevice();
                   gConfig = gDevice.getDefaultConfiguration();
              image = gConfig.createCompatibleImage(compSize.width, compSize.height);
              JComponent jc = (JComponent) ObjectFactory.instantiate(objectClass);
              jc.setSize(compSize);
              Graphics g = image.getGraphics();
              g.setColor(Color.LIGHT_GRAY);
              g.fillRect(0, 0, compSize.width, compSize.height);
              g.setColor(Color.BLACK);
              jc.paint(g);
              return image;
    }And here is the class that makes the dragable JLabel using the class above...public class Dragable extends JLabel
         private static DragSource dragSource = DragSource.getDefaultDragSource();
         private static DragGestureListener dgl = new DragMoveGestureListener();
         private static TransferHandler th = new ObjectTransferHandler();
         private Class compClass;
         private Image image;
         Dragable(Class compClass)
              this.compClass = compClass;
              image = JComponentImage.getImage(compClass);
              setIcon(new ImageIcon(image));
              setTransferHandler(th);
              dragSource.createDefaultDragGestureRecognizer(this,
                                                          DnDConstants.ACTION_COPY,
                                                          dgl);
         public Class getCompClass()
              return compClass;
    }Oh and here is ObjectFactory which simply instantiates Objects of a given class and sets their text to their classname (very crudely)...public class ObjectFactory
         public static Object instantiate(Class objectClass)
              Object o = null;
              try
                   o = objectClass.newInstance();
              catch (Exception e)
                   System.out.println("ObjectFactory#instantiate: " + e);
              String name = objectClass.getName();
              int lastDot = name.lastIndexOf('.');
              name = name.substring(lastDot + 1);
              if (o instanceof JLabel)
                   ((JLabel)o).setText(name);
              if (o instanceof JButton)
                   ((JButton)o).setText(name);
              if (o instanceof JTextComponent)
                   ((JTextComponent)o).setText(name);
              return o;
    }Two more classes required by this codepublic class ObjectTransferHandler extends TransferHandler {
         private static DataFlavor df;
          * Constructor for ObjectTransferHandler.
         public ObjectTransferHandler() {

  • Need help with basic program.....!

    I've to write a program that generates a random number, which the user has to try and guess, after each guess they're told whether it's too high or too low etc., I've gotten this far, however, the user has only 10 guesses.... In my program I've used a while loop and the user gets an infinite number of guesses, I know I'm supposed to use a for loop, but can't seem to get it to work properly. Also, when the user guesses the number, the program then has to print out how many guesses it took, and I have no idea how to get it to do this AT ALL!!! I'd really appreciate some help with this, thanks v. much!!!!

    help with this, thanks v. much!!!!Hey not every book covers every aspect of Java (if you haven't got a book and don't want to buy 1 i recommend an online tutorial) If u want the user to have an infinate number of guesses, use an infinate while loop. Put this in a file called app.java:
    import java.applet.Applet;
    import java.awt.*;
    import java.awt.event.*;
    import javax.swing.*;
    public class app extends Applet implements ActionListener
         JLabel lbl=new JLabel("Guess a number between 0 and 10:");
         JTextField txtfield=new JTextField(20);
         JButton button=new JButton("Guess...");
         JLabel lbl2=new JLabel();
         int randomnumber=Math.round((float)Math.random()*10);
         public void init()
              add(lbl);
              add(txtfield);
              add(button);
              button.addActionListener(this);
         public void actionPerformed (ActionEvent e)
              String s=new String("");
              s+=randomnumber;
              if (e.getSource().equals(button) && txtfield.getText().equals(s))
                   setBackground(Color.white);
                   setForeground(Color.black);
                   lbl2.setText("Got it!");
                   add(lbl2);
                   validate();
              else
                   setBackground(Color.white);
                   setForeground(Color.black);
                   if (Integer.parseInt(txtfield.getText())>randomnumber)
                   lbl2.setText("Too High!");
                   else
                   lbl2.setText("Too Low!");
                   add(lbl2);
                   validate();
    Then create a HTML document in the classes folder:
    <HTML>
    <HEAD>
    <TITLE>APPLET</TITLE>
    </HEAD>
    <BODY>
    <HR>
    <CENTER>
    <APPLET
         CODE=app.class
         WIDTH=400
         HEIGHT=200 >
    </APPLET>
    </CENTER>
    <HR>
    </BODY>
    </HTML>
    It will do what you wish. If you want to have more then 10 numbers to guess, for example 100, do this:
    int randomnumber=Math.round((float)Math.random()*100);
    Does that answer your question?

  • Need Help for -  JTextField outputs

    Hello everyone im back =P
    Just finished a code...and now i'd like to print the output using the JTextField , but it seems im having some problems :) ....don't know how to print the String.
    for JOptionPane its easy , we use JOptionPane.showMessag....etc
    we have also System.out...but i want to print this string with the JTextField, does anyone can help with that? thnks
                double m = complexo.module(r,i);
                double a = complexo.angle(r,i);
         String text = "Module: "+ Double.toString(m) + "\nAngle: " + Double.toString(a); 
    // I want to print  that String -> text
         JTextField  output = new JTextField(100);
         JPanel p = new JPanel();
         p.add(output);
         output.setText(text);
         output.setEditable(false);
    /** Is that ok ? do i have to use the JPanel or the JFrame ?  , well i just 
    *   want to print  that string  (text)  using the JTextField */ thnks

    In the future, Swing related questions should be posted in the Swing forum.
    and now i'd like to print the output using the JTextFieldLets get some terminoligy correct first. "Print" means you want to send the text to a printer so it can be printed on paper. I don't think thats what you want to do.
    You want to display the text on your monitor using a GUI. In that case you need to create a GUI container that contains a JTextField that will display the text.
    Start by read the Swing tutorial on [url http://java.sun.com/docs/books/tutorial/uiswing/components/toplevel.html]How to Use Top Level Containers. The tutorial also has a section on using text components which shows you how to use a text field.

  • Help with dropdown menu in JCombo box,Pleaseeeeeee

    Hi,
    I posted earlier but I`II try again. Someone must know how to do this. I have a JComboBox and I want the drop down menu to be a bit wider then the comboBox.
    I tried using this method
    public void setPreferredSize()
              Dimension d = jcbo.getPreferredSize(d);
              jcbo.setPreferredSize(new Dimension(20, d.height));
              jcbo.setPopupWidth(d.width);
    but I recieved a couldn`t resolve symbol error for the last line.
    I imported these into the program]
    import java.awt.*;
    import java.awt.event.*;
    import javax.swing.*;
    Is there something else I should of imported as well to make this work, or is it another problem all together.Any help would be greatly appreciated.

  • Need Help with Listener on JInternalFrame

    Below is the code as it is currently.
    public class addCustomer extends JInternalFrame implements ActionListener{
    //Variable declarations here
    private JPanel panel = new JPanel();
    private JLabel label1,label2,label3,label4,label5,label6,label7,label8,label9,icon1;
    private JTextField CustNum,CFName,CSName,Address1,Address2,City,PostCode,Tel,Cell;
    private JButton Cancel, Add;
    private ImageIcon pic,FrmPic;
    addCustomer() {
    super ("Add New Customer",true,true,true,true);
    setSize(350,370);
    setResizable(false);
    On the Frame I have a textfield that I would like to add a listener to. When text is typed into the textfield it should enable a JButton on the frame. My problem is that as soon as I implement KeyListener or EventListener on the above code I get an error of the class is not defined as abstract. If I define it as abstract my main declaration that looks like this gives me an error :
    public static void main(String args[]){
    new Video().show();
    Can anyone help me with a work around.

    I have the following cursor and and want to use if else statement to get the output. The cursor is working fine. What i need help with is how to use and if else statement to only get the folderrsn that have not been updated in the last 30 days. If you look at the talbe below my select statement is showing folderrs 291631 was updated only 4 days ago and folderrsn 322160 was also updated 4 days ago.
    I do not want these two to appear in my result set. So i need to use if else so that my result only shows all folderrsn that havenot been updated in the last 30 days.
    Here is my cursor:
    /*Cursor for Email procedure. It is working Shows userid and the string
    You need to update these folders*/
    DECLARE
    a_user varchar2(200) := null;
    v_assigneduser varchar2(20);
    v_folderrsn varchar2(200);
    v_emailaddress varchar2(60);
    v_subject varchar2(200);
    Cursor c IS
    SELECT assigneduser, vu.emailaddress, f.folderrsn, trunc(f.indate) AS "IN DATE",
    MAX (trunc(fpa.attemptdate)) AS "LAST UPDATE",
    trunc(sysdate) - MAX (trunc(fpa.attemptdate)) AS "DAYS PAST"
    --MAX (TRUNC (fpa.attemptdate)) - TRUNC (f.indate) AS "NUMBER OF DAYS"
    FROM folder f, folderprocess fp, validuser vu, folderprocessattempt fpa
    WHERE f.foldertype = 'HJ'
    AND f.statuscode NOT IN (20, 40)
    AND f.folderrsn = fp.folderrsn
    AND fp.processrsn = fpa.processrsn
    AND vu.userid = fp.assigneduser
    AND vu.statuscode = 1
    GROUP BY assigneduser, vu.emailaddress, f.folderrsn, f.indate
    ORDER BY fp.assigneduser;
    BEGIN
    FOR c1 IN c LOOP
    IF (c1.assigneduser = v_assigneduser) THEN
    dbms_output.put_line(' ' || c1.folderrsn);
    else
    dbms_output.put(c1.assigneduser ||': ' || 'Overdue Folders:You need to update these folders: Folderrsn: '||c1.folderrsn);
    END IF;
    a_user := c1.assigneduser;
    v_assigneduser := c1.assigneduser;
    v_folderrsn := c1.folderrsn;
    v_emailaddress := c1.emailaddress;
    v_subject := 'Subject: Project for';
    END LOOP;
    END;
    The reason I have included the folowing table is that I want you to see the output from the select statement. that way you can help me do the if statement in the above cursor so that the result will look like this:
    emailaddress
    Subject: 'Project for ' || V_email || 'not updated in the last 30 days'
    v_folderrsn
    v_folderrsn
    etc

    How do I incorporate a if else statement in the above cursor so the two days less than 30 days since last update are not returned. I do not want to send email if the project have been updated within the last 30 days.

    Hoping for some help with a very frustrating issue!
    I have been syncing calendar and contacts on my iPhone 5 and Outlook 2007 using iCloud  2.1.3 (my PC is running Vista). All was well until the events I entered on the phone were showing up in Outlook, but not the other way around. I’ve tried the usual recommended steps: deselecting calendar and contacts in the iCloud control panel and then re-selecting, signing out of the panel and back in, and repairing the Outlook installation in control panel.  I even uninstalled iCloud on the PC and downloaded it again (same version). 
    The furthest I’ve gotten is step 2 (and once, step 3) of 7 while performing “Outlook Setup For iCloud.” At that point I get, “Your setup couldn’t be started because of an unexpected error.”  After the first attempt at all this, all my calendar events disappeared from Outlook, although they are still in iCloud calendar and on my phone.
    Sound familiar?  Any ideas on how to solve this iCloud/Outlook issue?  Thanks much in advance!
