How can we add components to JPanel so that they can be resizeable

Is it possible to add components to JPanel so that we can resize them or drag them.

You could try searching the forums, but I'll save you the trouble. tjacobs has oft posted code which does what you want, both dragging and resizing.
You can find an example here or here.

Can not add a picture to the JFrame from an ActionListener class

As topic says, I can not add a picture to the JFrame from an ActionListener class which is a class inside the JFrame class.
I have a Map.java class where I load an image with ImageIcon chosen with JFileChooser.
I my window class (main class), I have following:
class OpenImage_Listener implements ActionListener
     public void actionPerformed(ActionEvent e)
          int ans = open.showOpenDialog(MainProgram.this);     // "open" is the JFileChooser reference
          if(ans == open.APPROVE_OPTION)
               File file = open.getSelectedFile();
               MainProgram.this.add(new Map(file.getName()), BorderLayout.CENTER);     // this line does not work - it does not add the choosen picture on the window,
                        //but if I add the picture outside this listener class and inside the MainProgram constructor, the picture apperas, but then I cannot use the JFileChooser.
                        showMessageDialog(MainProgram.this, fil.getName() ,"It works", INFORMATION_MESSAGE); // this popup works, and thereby the ActionListener also works.
}So why can�t I add a picture to the window from the above listener class?

The SSCCE:
Ok, I think I solved it with the picture, but now I cannot add new components after adding the picture.
Look at the comment in the actionlistener class:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.io.*;
public class Test extends JFrame{
     JButton b = new JButton("Open");
     JFileChooser jfc = new JFileChooser(System.getProperty("user.dir"));
     Picture pane;
     Test(){
          super("Main Program");
          setLayout(new BorderLayout());
          JPanel north = new JPanel();
          add(north, BorderLayout.NORTH);
          north.add(b);
          b.addActionListener(new Listener());
          setVisible(true);
          setSize(500,500);
          pane = new Picture("");
          add(pane, BorderLayout.CENTER);
     class Listener implements ActionListener {
          public void actionPerformed(ActionEvent e){
               int ans = jfc.showOpenDialog(Test.this);
               if(ans == jfc.APPROVE_OPTION)
                    File file = jfc.getSelectedFile();
                    Test.this.add(new Picture(file.getName()), BorderLayout.CENTER);
                    pane.add(new JButton("NEW BUTTON")); // Why does this button not appear on the window???
                    pane.repaint();
                    pane.revalidate();
     public static void main(String[] args)
          Test t = new Test();
class Picture extends JPanel
     Image pic;
     String filename;
     Picture(String filename)
          setLayout(null);
          this.filename = filename;
          pic = Toolkit.getDefaultToolkit().getImage(filename);
        protected void paintComponent(Graphics g)
            super.paintComponent(g);
            g.drawImage(pic,0,0,getWidth(),getHeight(),this);
            revalidate();

Don't know exactly what you mean but this is how I add a JPanel to a JScrollPane.
public class Scroll extends JFrame{
JScrollPane jsp;
JPanel panel;
public Scroll(){
jsp = new JScrollPane();
panel = new JPanel();
jsp.getViewPort().add(panel);
getContentPane().add(jsp, BorderLayout.CENTER)
}

Can I add a JPanel in JScrollPane?

Can I add a JPanel in JScrollPane?
If I added,components in the JPanel can effect the JScrollPane?
thanks!

Can I add a JPanel in JScrollPane?yes you can - it is meant for this.
If I added,components in the JPanel can effect the
JScrollPane?if you mean affect like focusing and scrolling to a certain place - the answer is yes, you have to look the right functions in each component you insert to the panel.

}Now the problem I'm having is changing that class to a JFrame, it seems simple but I keep having problems like when it runs from another JFrame nothing pops up. I can do it like this:
FinalTest ft = new FinalTest();
ft.setVisible(false);
JPanel example = ft.contentPanehowever I will probably be marked down on this for bad code. I'm not asking for the work to be done for me, but I'm really stuck on this and just need some pointers so I can carry on with the project. Thanks,

You can maybe explore button and forms feature in InDesign. It was added in CS6.

Best recommendataion to work with one JFrame & Multiple Jpanels(or Windows)

Hi all,
I am a bit new(bie) to Java and Gui but not new to programming.
I need to write an application in using Java. The Current editor I use is Netbeans.
I have a rough idea on how to write this apps, but I would like to confirm if my idea is applicable to such application (from a performance and feasibility standpoint).
The main idea for this application is to have multiple forms that users would populate, and the values entered will be stored in a Database.
I had plan to use only one main Window (JFrame), and no MDI, no multiple Java windows.
My plan was:
-     Create the main form (JFrame) with menus, once the application is loaded, I will check if a database connection is available otherwise open a Jpanel to input database settings (which can be started from the menu).
-     All menus and application/company settings would be set in the main form
-     All features available in the Jpanel would be in a separate class for clarity/lisibility of my code. For instance : user settings would be a separate jpanel class; database settings is a new jpanel class
-     Each Jpanel class would be stored in a separate java/class file.
Here is my test example for now (file MainForm.java) :
import javax.swing.*;
public class MainForm extends JFrame {
    /* Initializing a few variables */
    String databaseServer = null;
    String databaseUserName = null;
    String databasePassword = null;
    /** Creates new form MainForm */
    public MainForm() {
        /* Initializing menus */
        initComponents();
       /* starting a new instance of database configuration */
        DbPanel test = new DbPanel();
    /* Initialization menu and graphical components */
    private void initComponents () {
        JMenuBar BarMenu;
        JMenu MenuConfiguration;
/* �.*/
     BarMenu.add(MenuConfiguration);
     setJMenuBar(BarMenu);
     pack();
     * @param args the command line arguments
    public static void main(String args[]) {
        java.awt.EventQueue.invokeLater(new Runnable() {
            public void run() {
                new MainForm().setVisible(true);
} Here is my DBpanel class (file MainForm.java) :
public class DbPanel extends javax.swing.JPanel {
    /** Creates new form DbPanel */
    public DbPanel() {
        initComponents();
// <editor-fold defaultstate="collapsed" desc=" Generated Code ">
    private void initComponents() {
        java.awt.Button buttonClose;
        java.awt.Button buttonSave;
        java.awt.TextField dbName;
/* � */
       gridBagConstraints.ipadx = 100;
        gridBagConstraints.insets = new java.awt.Insets(0, 21, 0, 21);
        add(dbPassword, gridBagConstraints);
// </editor-fold>
}Here are then my questions:
-     Would you think that is a practical plan to write such application?
-     Once I display a Jpanel form and I close it (for instance myJpanel.setVisible=false), will the memory be freed?
-     Is there any other way to remove entire a JPanel from RAM?
-     How can I call my �external� Jpanel ? I have designed one Jpanel class for testing but I was not able to display it when I created the new instance of that class.
-     Is there any other alternative to Jpanel for this application? I was thinking about opening a new window within my Jframe. But, ideally it would be best that multiple windows are not opened simultaneously.
Thanks for your input

I was thinking about this but requirements are the
application development cost should be reduced to the
minimum.
thus one desktop application and one database
server.Application development cost? If you are being paid to do this, the bulk of the cost will be your hourly rate times the number of hours it takes you to do it. Thus you want to minimize the number of hours it takes you to do it. Assuming that the cost of your learning Java is going to be charged to this project, it might well be a good idea for you to do it in a language you already know. Or one where it's easy to develop this sort of application.

Change jFrame to JPanel

I have a gui that uses Jframe how easy would it be to change it to use jPanel instead? would it just be a few tweeks or would i be basically writting my code again?
Also kind of off topic but if any one could give there view i'd be very happy
The class file that uses the GUI is for entering names and DOB's, the same class can also be used for reading it back in again (data gets saved to a file) in your opinion which would look best
if i split the gui in half so the left side was for entering and the right hand side was for reading in or
if i just had it so there was one lot of text fields which could be used to enter data and if you read in the file would show the data from the file?

I have a gui that uses Jframe how easy would it be to change it to use jPanel instead?You already are already using panels most likely.
All GUI's need a top level container (JFrame, JDialog or JWindow). To the top level container you add Swing components (JPanel, JButton, JTextField, JTable etc...).
So your question doesn't make any sense.
Take a look at the Swing tutorial which has a [url http://java.sun.com/docs/books/tutorial/uiswing/components/components.html]Visual Index of Swing Componentsurl. Click on each component and you will find example programs that use the component and you can see how the program is structured and use that approach in your design.

Inserting a Gui program using JFrames and JPanel

I'm trying to insert a chat program into a game that I've created! The chat program is using JFrames and JPanels. I want to insert this into a GridLayout and Panel. How can I go about doing this?

whatever is in the frame's contentPane now, you add to a separate JPanel.
you also add your chat stuff to the separate panel
the separate panel is added to the frame as the content pane

JFram or Jpanel maximum size

How should I set maximum and minimum size of JFrame (or JPanel using BorderLayout) ? Please note setPreferredSize() and setMaximumSize() are not effective.
Thanks

You can't set the min/max size of a JPanel in a BorderLayout.
You can't directly set the min/max size of a JFrame, but you can add a ComponentListener the the JFrame and resize the JFrame when it exceeds you specified sizes.
Search the forum using "+maximum +addcomponentlistener".
Of course since this is a Swing question, you should be searching the Swing forum.

How can i refresh JFrame at regular intervals to display in intervals

I have a query which is :
String query = "select FIRSTNAME, MIDDLEINITIAL, LASTNAME from user" ;
now i have executed the above query
ResultSet rs = stmt.executeQuery(query) ;
Suppose i get 2000 rows in my resultset after execution.
If i want to display all the contents of my query inside a JFrame, then i can say
JFrame myFrame = new JFrame() ;
myFrame.setSize(500, 500) ;
while(rs.next()){
add the results to myFrame
myFrame.pack() ;
myFrame.setVisible() ;
but this may take a long time to show my frame, because first it has to either add components to my JFrame if use JLabels or if i use graphics then it has to wait till complete all of my drawString's to display the JFrame.
and this may take time.
I would like to know, how can make my JFrame intelligent enough so that if first display an empty frame, refresh at regular intervals and see how many i have fetched from the result set and add those to my JFrame, and do this opration untill i am done fetching all the results.
Thanks
Arun

Any reason why you aren't displaying the results in a table? Both labels and drawString do not seem like a good alternative.
Now to your question, you could use a thread and force painting after so many from the resultset. You could display a fixed number and implement your own scrolling scheme. Say paint first 50 and scrolling forward and back.

Can I add multiple swing elements on a single line.

Im adding a number of labels to the JPanel -- is there a way to add them all on one line as opposed to:
c.add(top1);
c.add(top2); etc. etc.?

Im adding a number of labels to the JPanel -- is
there a way to add them all on one line as opposed
to:
c.add(top1);
c.add(top2); etc. etc.?well you can do
c.add(top1); c.add(top2);
but basically no, you can't add them all together at the same time

Can we add JFrame to JPanel?
