Linking gui's

how do i get a button, that when pressed will display another gui?
need help urgent.....
thanks

Hi,
If your class files are below the code base and your package setup
reflects this then it should work. If you put your code in one file
representing several classes then this will work also without
setting any package names.
Look at the demo code under the JDK install directory
demo/applets this should help you or take a look
at the tutorial this walks you through an example.

New help on java swing GUI.....

k, im new to java. Just started learning a month ago. Anyway, I was wondering how one can link gui together using buttons. For example, when i press enter on a registration gui, it'll take me to the confirmation gui. What's the best way to do this? anyone has any idea or can point me to a website with info. Thanks A lots folks.

Well, bascially you would add a Button (e.g. "Next" or "Submit") to your Window/Panel (whatever you prefer). This add has an ActionListener assigned which will open up the next Window/Panel.
Then you define this button to be your default button on that window (check JRootPane.setDefaultButton() for this) so that Enter will fire the button.
Check the Swing online tutorial for an introduction to Swing and how Buttons (and their associated ActionListener) work.

Linking "ant" project with GUI

Hello,
I have an "ant" project (is a speech recognition system) that I want to link to a GUI. I did not make the "ant" project but I know how to use it; I have no experience working with "ant" projects or files.
Does anyone have any ideas? or, Does anyone have a link where I can learn more about "ant"? I'm using netbeans for my application. I googled ant but have not found anything that can help; I'll keep googling but suggestions are appreciated.

Making clickable links in GUI?

Hi,
Well, I'm making an GUI application and I wanted to have a clickable link to my website, I thought using HTML would be a good bet, but it doesn't work, I was thinking of using util but I'm not exactly sure..

Swing related questions should be posted in the Swing forum.
JEditorPane provide some basic support for loading HTML pages. Read the API for more info.
You can invoke IE as follows:
** Here is a pure Windows solution
** Run the code and you will be taken to a tutorial that may provide
** a more generic solution
public class WindowsFileProtocolHandler
     public static void main(String[] args)
          throws Exception
          String[] cmd = new String[4];
          cmd[0] = "cmd.exe";
          cmd[1] = "/C";
          cmd[2] = "start";
          cmd[3] = "http://www.javaworld.com/javaworld/javatips/jw-javatip66.html";
//          cmd[3] = "will.xls";
//          cmd[3] = "mailto:";
//          cmd[3] = "a.html";
//          cmd[3] = "file:/c:/java/temp/a.html";
          Process process = Runtime.getRuntime().exec( cmd );

Linking output to gui

Im trying to link the output text terminals contents to be displayed within the gui, is using a JtextArea the correct way to do this, and also is there a shortcut such as copying the contents straight into the gui window? ive checked the APi but have either overlooked or cant find an item to do this.
thanks!

If I understand you, there is no shot cut to using setText or append. One
handy method that is often overlooked is
read(Reader , Object )
Which would help copy from a file, but not from the console, unless stdin is
being redirected from a file :-)

It is simple and very annoying.
I think you should try to do it yourself to learn how Java works, it is a good exercise for you.
The forum is used to work together on different problems, giving tips and ideas but not coding for other people.
About your problem, two things : you should rewrite all the code (not trying to link these two classes) and you will have serious problems wityh the different setLayout you use !

Saving to text file from GUI within linked list

can anyone help me with saving to a text file from a GUI text area and text fields??
then reading back into the labels and textfields from the text file??
It's currently just saving in a linked list and creating a new item inside of it. but i have to now make a text file for each item, this is what i currently have
i need to turn this into something that with save to text file with buffered reader or something, can anyone help???
public void saveToFile()
        while(listIterator.hasNext())
            item = (Item)listIterator.next();
            saving.save(item);
    }//END SAVETOFILE
    public Object save(Item item)
        if (last == 1)
            itemList.set( listIterator.nextIndex() , item);
        else
            itemList.set(listIterator.previousIndex(), item);
        itemList.set(listIterator.previousIndex(), item);
        listIterator = itemList.listIterator(0);
        return itemList.getFirst();
    }//END SAVE

thank you sztyopek, i am still having trouble getting it to save to text file. I have to do it through a client and server so i have a protocol class. in the protocol class i have
if (o instanceof String)
                    //System.out.println(o);
                    if (o.equals("next"))
                        newo = database.getNextItem();
                       // some how send newo
                    if (o.equals("prev"))
                        newo = database.getPrevItem();
                        //some how send newo
                    if (o.equals("save"))
                        database.saveToFile();
                    if (o.equals("exit"))
                        System.exit(1);
                }//END IF STRING
         if (o instanceof Item)
           newo = database.save((Item)o);
        return newo;
    }When i save what i have entered in the textfields for each record it doesn't create a textfile. and it still getting retrieved from how i set it up before by going to the database.save((Item)o)...the last if statement above but i can't change that to the saveToFile method that u helped me with it says incompatible types or something.
this is the method it is going to, i assume i have to get rid of this so i stop getting the information from the list and start getting it from the text file.
public Object save(Item item)
        if (last == 1)
            itemList.set( listIterator.nextIndex() , item);
        else
            itemList.set(listIterator.previousIndex(), item);
        itemList.set(listIterator.previousIndex(), item);
        listIterator = itemList.listIterator(0);
        return itemList.getFirst();
    }//END SAVEif this makes any sense can u give me a hand.

GUI Linking

I have been set an assignment to connect a java program to an oracle database. I wanted to put a GUI interface on top of the program. I was wondering how you can connect the GUI together for example on my code i have a read in from database button and when it is pressed i want it to read in data from the database and then i want it to go to a separate GUI that can display the data. How would i display the data would it have to be put into a large text box or is there a more appropriate way of doing this. Also how would i simply link two GUI interfaces together so that when one is pressed with for example a button to say to next it would go to another menu. Sorry if this is very wordy. I'm not sure if you would just use a extends or something like that.
import javax.swing.*;
import java.awt.*;

public class LeagueGUI extends JFrame implements ActionListener{
     private JPanel pnlPanel;
     private JButton btnRead, btnUpdate, btnReadDatabase, btnDisplayUpdated;
     private JFrame frmFrame;
    private JLabel lblpicture;
     public LeagueGUI(){
          setTitle("League Table");
          setSize(900,600);
        pnlPanel = new JPanel();
          pnlPanel.setLayout(null);
        pnlPanel.setBackground(Color.blue);
        ImageIcon LeagueGUI = new ImageIcon("Premier.jpg");
        lblpicture = new JLabel(LeagueGUI);
        lblpicture.setBounds(430, 10, 100, 500);
        pnlPanel.add(lblpicture);
        btnRead = new JButton("Match Results");
          btnRead.setBounds(50, 450, 200, 100);
          btnRead.addActionListener(this);
          pnlPanel.add(btnRead);
          btnUpdate = new JButton("Update");
          btnUpdate.setBounds(250, 450, 200, 100);
          btnUpdate.addActionListener(this);
          pnlPanel.add(btnUpdate);
        btnReadDatabase = new JButton("Read Database");
          btnReadDatabase.setBounds(450, 450, 200, 100);
          btnReadDatabase.addActionListener(this);
          pnlPanel.add(btnReadDatabase);
        btnDisplayUpdated = new JButton("Display Updated");
          btnDisplayUpdated.setBounds(650, 450, 200, 100);
          btnDisplayUpdated.addActionListener(this);

          getContentPane().add(pnlPanel);
          setVisible(true);
        public void actionPerformed(ActionEvent event) {
          Object source = event.getSource();
          if (source == btnRead)     {
          else if (source == btnUpdate) {
         public static void main(String[] args)     {
          LeagueGUI League = new LeagueGUI();
}thank you in advance for your help please let me know if u need more specific information.

if i were doing this i would first write a bunch of functions that will handle connecting to the database and getting back the values formatted the way you will want them displayed.
after that i would start working on the GUI and linking it all together. you can easily add listeners to buttons (and other things) that can detect when they have been clicked -- once you detect the click you can call any functions / do anything you'd like (in this case you would call the database code you wrote).
if you google around you should be able to find some basic JDBC examples of java connecting to oracle databases.
let me know if you need anything else.
