Problem with JFrame and JPanel
Okay, well I'm busy doing a lodge management program for a project and I have programmed this JFrame
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class FinalTest extends JFrame
public JPanel contentPane;
public JImagePanel imgPanel;
private JLabel[] cottageIcon;
private boolean keepMoving;
private int selectedCottage;
public FinalTest()
super();
initializeComponent();
addActionListeners();
this.setVisible(true);
private void initializeComponent()
contentPane = (JPanel)getContentPane();
contentPane.setLayout(null);
imgPanel = new JImagePanel("back.png");
imgPanel.setLayout(null);
imgPanel.setBackground(new Color(1, 0, 0));
addComponent(contentPane, imgPanel, 10,10,imgPanel.getImageWidth(),imgPanel.getImageHeight());
cottageIcon = new JLabel[6];
keepMoving = true;
selectedCottage = 0;
cottageIcon[0] = new JLabel();
//This component will never be added or shown, but needs to be there to cover for no cottage selected
for(int a = 1; a < cottageIcon.length; a++)
cottageIcon[a] = new JLabel("C" + (a));
cottageIcon[a].setBackground(new Color(255, 0, 0));
cottageIcon[a].setHorizontalAlignment(SwingConstants.CENTER);
cottageIcon[a].setHorizontalTextPosition(SwingConstants.LEADING);
cottageIcon[a].setForeground(new Color(255, 255, 255));
cottageIcon[a].setOpaque(true);
addComponent(imgPanel,cottageIcon[a],12,(a-1)*35 + 12,30,30);
this.setTitle("Cottage Chooser");
this.setLocationRelativeTo(null);
this.setSize(new Dimension(540, 430));
private void addActionListeners()
imgPanel.addMouseListener(new MouseAdapter()
public void mousePressed(MouseEvent e)
imgPanel_mousePressed(e);
public void mouseReleased(MouseEvent e)
imgPanel_mouseReleased(e);
public void mouseEntered(MouseEvent e)
imgPanel_mouseEntered(e);
imgPanel.addMouseMotionListener(new MouseMotionAdapter()
public void mouseDragged(MouseEvent e)
imgPanel_mouseDragged(e);
private void addComponent(Container container,Component c,int x,int y,int width,int height)
c.setBounds(x,y,width,height);
container.add(c);
private void imgPanel_mousePressed(MouseEvent e)
for(int a = 1; a < cottageIcon.length; a++)
if(withinBounds(e.getX(),e.getY(),cottageIcon[a].getBounds()))
System.out.println("B" + withinBounds(e.getX(),e.getY(),cottageIcon[a].getBounds()));
selectedCottage = a;
keepMoving = true;
private void imgPanel_mouseReleased(MouseEvent e)
System.out.println("called");
selectedCottage = 0;
keepMoving = false;
private void imgPanel_mouseDragged(MouseEvent e)
System.out.println("XXX" + Math.random() * 100);
if(keepMoving)
int x = e.getX();
int y = e.getY();
if(selectedCottage!= 0)
cottageIcon[selectedCottage].setBounds(x-(30/2),y-(30/2),30,30);
if(!legalBounds(imgPanel,cottageIcon[selectedCottage]))
keepMoving = false;
cottageIcon[selectedCottage].setBounds(imgPanel.getWidth()/2,imgPanel.getHeight()/2,30,30);
System.out.println(cottageIcon[selectedCottage].getBounds());
private void imgPanel_mouseEntered(MouseEvent e)
System.out.println("entered");
private void but1_actionPerformed(ActionEvent e)
String input = JOptionPane.showInputDialog(null,"Enter selected cottage");
selectedCottage = Integer.parseInt(input) - 1;
public boolean legalBounds(Component containerComponent, Component subComponent)
int contWidth = containerComponent.getWidth();
int contHeight = containerComponent.getHeight();
int subComponentX = subComponent.getX();
int subComponentY = subComponent.getY();
int subComponentWidth = subComponent.getWidth();
int subComponentHeight = subComponent.getHeight();
if((subComponentX < 0) || (subComponentY < 0) || (subComponentX > contWidth) || (subComponentY > contHeight))
return false;
return true;
public boolean withinBounds(int mouseX, int mouseY, Rectangle componentRectangle)
int componentX = (int)componentRectangle.getX();
int componentY = (int)componentRectangle.getY();
int componentHeight = (int)componentRectangle.getHeight();
int componentWidth = (int)componentRectangle.getWidth();
if((mouseX >= componentX) && (mouseX <= (componentX + componentWidth)) && (mouseY >= componentY) && (mouseY <= (componentY + componentWidth)))
return true;
return false;
public static void main(String[] args)
JFrame.setDefaultLookAndFeelDecorated(true);
//JDialog.setDefaultLookAndFeelDecorated(true);
try
UIManager.setLookAndFeel("com.sun.java.swing.plaf.windows.WindowsLookAndFeel");
catch (Exception ex)
System.out.println("Failed loading L&F: ");
System.out.println(ex);
FinalTest ft = new FinalTest();
import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.Image;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class JImagePanel extends JPanel
private Image image;
public JImagePanel(String imgFileName)
image = new ImageIcon(imgFileName).getImage();
setLayout(null);
public void paintComponent(Graphics g)
g.drawImage(image, 0, 0, null);
public Dimension getImageSize()
Dimension size = new Dimension(image.getWidth(null), image.getHeight(null));
return size;
public int getImageWidth()
int width = image.getWidth(null);
return width;
public int getImageHeight()
int height = image.getHeight(null);
return height;
}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,
Steve

I'd actually consider your GUI being a JPanel instead of a JFrame quite good design - makes it easy to put the stuff into an applet when necessary...
Anyway, you should set setVisible() to true to make it appear, not to false. Otherwise, I don't seem to understand your problem.That is actually my problem. I am trying to convert this JFrame to a JPanel

Advance level drawing problem with Jframe and JPanel need optimize sol?
Dear Experts,
I m trying to create a GUI for puzzle game following some kind of "game GUI template", but i have problems in that,so i tried to implement that in various ways after looking on internet and discussions about drawing gui in swing, but i have problem with both of these, may be i m doing some silly mistake, which is still out of my consideration. please have a look at these two and recommend me one of them, which is running without problems (flickring and when you enlarge window the board draw copies (tiled) everywhere,

Problem with JFrame and busy/wait Cursor
Hi -- I'm trying to set a JFrame's cursor to be the busy cursor,
for the duration of some operation (usually just a few seconds).
I can get it to work in some situations, but not others.
Timing does seem to be an issue.
There are thousands of posts on the BugParade, but
in general Sun indicates this is not a bug. I just need
a work-around.
I've written a test program below to demonstrate the problem.
I have the problem on Solaris, running with both J2SE 1.3 and 1.4.
I have not tested on Windows yet.
When you run the following code, three JFrames will be opened,
each with the same 5 buttons. The first "F1" listens to its own
buttons, and works fine. The other two (F2 and F3) listen
to each other's buttons.
The "BUSY" button simply sets the cursor on its listener
to the busy cursor. The "DONE" button sets it to the
default cursor. These work fine.
The "SLEEP" button sets the cursor, sleeps for 3 seconds,
and sets it back. This does not work.
The "INVOKE LATER" button does the same thing,
except is uses invokeLater to sleep and set the
cursor back. This also does not work.
The "DELAY" button sleeps for 3 seconds (giving you
time to move the mouse into the other (listerner's)
window, and then it behaves just like the "SLEEP"
button. This works.
Any ideas would be appreciated, thanks.

I still believe you would need a thread for the time consuming task, and that invokeLater is something you only need to use in a thread different from the event thread. -
Problem with JTable and JPanel
Hi,
I'm having problems with a JTable in a JPanel. The code is basicly as follows:
public class mainFrame extends JFrame
public mainFrame()
//A menu is implemeted giving rise to the following actions:
public void actionPerformed(ActionEvent evt)
String arg = evt.getActionCommand();
if(arg.equals("Sit1"))
//cells, columnNames are initiated correctly
JTable table = new JTable(cells,columnNames);
JPanel holdingPanel = new JPanel();
holdingPanel.setLayout( new BorderLayout() );
JScrollPane scrollPane = new JScrollPane(holdingPanel);
holdingPanel.setBackground(Color.white);
holdingPanel.add(table,BorderLayout.CENTER);
add(scrollPane, "Center");
if(arg.equals("Sit2"))
if(scrollPane !=null)
remove(scrollPane);validate();System.out.println("ScrollPane");
if(holdingPanel !=null)
remove(holdingPanel);
if(table !=null)
remove(table);table.setVisible(false);System.out.println("table");
//Put other things on the holdingPanel....
private JScrollPane scrollPane;
private JPanel holdingPanel;
private JTable table;
}The problem is that the table isn't removed. When you choose another situation ( say Sit2), at first the table apparently is gone, but when you press with the mouse in the area it appeared earlier, it appears again. How do I succesfully remove the table from the panel? Removing the panel doesn't seem to be enough. Help is much appreciated...
Best regards
SchwartzIf you reuse the panel and scroll pane throughout the application,
instantiate them in the constructor, not in an often-called event
handler. In the event handler, you only do add/remove of the table
on to the panel. You can't remove the table from the container
which does not directly contain it.
if (arg.equals("Sit2")){
holdingPanel.remove(table);
holdingPanel.revalidate();
holdingPanel.repaint(); //sometimes necessary
} -
Is there a problem with JFrame and window listeners?

Swing layout/size problem with JFrame and JApplet.
I have a class that extends a JFrame, the classes layout is BorderLayout. I then have a class that extend JApplet, this classes layout is GridBagLayout (this class has a JTabbedPane - which contains JPanels). The problem I'm having is no matter how big I make the size of the applet or frame (using setSize), the applet/frame stays the same size - no matter how large I make it.
Can anyone please help?

Problem with Graphics and JPanel...
I would like to draw a rectangle on a JPanel. Here is my code:
JPanel panel = new JPanel();
Graphics g = panel.getGraphics();
g.drawRect(20,20,20,20);
When I run my program, I have a NullPointerException...
Do you any suggestions to fix the problem??
thanks

Problem with writing and reading using serialization
I am having a problem with writing and reading an object that has another object in it. The purpose of the class is to write a order that has multiple items in it. And there will be several orders. This is for an IB project, where one of the requirements is to utilize a hierarchical composite data structure. That is, it is "one that contains more than one element and at least one of the elements is a composite data structure. Examples are, an array or linked list of records, a record that has one field that is another record, or an array". The code is shown below:
The error produced is
java.lang.NullPointerException

Problem with PropertyChangeListener and JTextField
I'm having a problem with PropertyChangeListener and JTextField.
I can not seem to get the propertychange event to fire.
Anyone have any idea why the code below doesn't work?

}If you want to listen to changes in the textfield's contents you should use a DocumentListener and not a PropertyChangeListener:

Problem with JFrame's dispose();
Hello everyone,
I'm having a problem with JFrame's dispose() method. In my program I have 2 classes which go into full screen. On each screen there is a button to switch to the other screen. The first time I push the button on both of them the other screen closes, which is what I want. However, if I push the same button more than twice - like by going from Screen1 to Screen2 and Screen2 to Screen1 and then Screen1 to Screen2 - I get 2 screens. If I keep doing that I eventually get 10+ screens up, which is bad. How do I prevent that?There's a lot of code, so I'll just post up the part that does it.
backButton.addActionListener(new ActionListener()
public void actionPerformed(ActionEvent e)
soundManagerM.close();
new MenuScreen().setVisible(true);
dispose();
});I don't think it opens up 2 at once, because it would play multiple music right? -
Problems with SwingWorker and classes in my new job, ;), can you help me?
Hi all, ;)
First of all, sorry about my poor English.
I have a problem with Swing and Threads, I hope you help me (because I'm in the firsts two weeks in my new job)
I have two classes:
Form1: Its a JPanel class with JProgressBar and JLabel inside.
FormularioApplet: (the main) Its a JPanel class with a form1 inside.
I have to download a file from a server and show the progress of the download in the JProgressBar. To make it I do this:
In Form1 I make a Thread that update the progress bar and gets the fole from the server.
In FormularioApplet (the main) I call to the method getDownloadedFile from Form1 to get the File.
THE PROBLEM:
The execution of FormularioApplet finishes before the Thread of Form1 (with download the file) download the file. Then, when I call in FormularioApplet the variable with the file an Exception: Exception in thread "AWT-EventQueue-1" java.lang.NullPointerException is generated.
First main begins his execution, then call to Form1 (a thread) then continues his execution and when the execution is finished ends the execution os Form1 and his thread.
How can I do for main class call the function and the Thread download his file after main class assign the file of return method?
How can I pass information froma class include an a main class. Form1 can't send to main (because main class made a Form1 f1 = new Form1()) any information from his end of the execution. I think if Form1 can say to main class that he finishes is job, then main class can gets the file.
I put in bold the important lines.
Note: My level of JAVA, you can see, is not elevated.
THANKS A LOT

Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
Change the channel on your wireless router. Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
Another thing to try - Go into your router security settings and change from WEP to WPA with AES.

Problems with MemoryImageSource and createImage
Hi!
As my headline says it, I have a problem with MemoryImageSource and createImage. Whenever I create an image from a memory buffer I get an image that has the wrong dimensions: the width and height are swapped, but the image seems to be all right. I tried to create the image ov top of a JPanel using the Container methods. Any suggestions as of how to solve this problem would be greatly appreciated.
Here is the code that I am using:
public class ImageCanvas extends JPanel
private Dimension SD;
private Image Img;
byte [][] ImageBuffer=new [150][100];
public ImageCanvas()
this(100,150,ImgBuffer);
public ImageCanvas(int sx,int sy,byte[][] buff)
D=new Dimension(sx,sy);
SD=new Dimension(sx,sy);
setSize(D);
setCursor(new Cursor(Cursor.DEFAULT_CURSOR));
setVisible(true);
int [] ipix=new int[sx*sy];
if(buff.equals(ImgBuffer)==false){
ImgBuffer=new byte[sy][sx];
for(int j=0;j<sy;j++){
System.arraycopy(buff[j],0,ImgBuffer[j],0,sx);
/* ARGB */
for(int j=0;j<sy;j++){
for(int i=0;i<sx;i++){
ipix[j*sx + i]=(0xFF000000 |
((ImgBuffer[j] << 16) & 0x00FF0000) |
((ImgBuffer[j][i] << 8) & 0x0000FF00) |
(ImgBuffer[j][i] & 0x000000FF));
Img = createImage(new MemoryImageSource(sx,sy,ipix,0,sx));
private void SetImage(byte[][] pixels)
int sx=pixels[0].length;
int sy=pixels.length;
SD.width=sx;
SD.height=sy;
if(ImgBuffer[0].length != sx && ImgBuffer.length != sy){
ImgBuffer = new byte[sy][sx];
for(int j=0;j<sy;j++){
System.arraycopy(pixels[j],0,ImgBuffer[j],0,sx);
int [] ipix=new int[sx*sy];
for(int i=0;i<sx;i++){
for(int j=0;j<sy;j++){
/* ARGB */
ipix[j*sx + i]=(0xFF000000 |
((ImgBuffer[j][i] << 16) & 0x00FF0000) |
((ImgBuffer[j][i] << 8) & 0x0000FF00) |
(ImgBuffer[j][i] & 0x000000FF));
Img = createImage(new MemoryImageSource(sx,sy,ipix,0,sx));
protected void paintComponent(Graphics g)
paint(g);
public void paint(Graphics g)
g.drawImage(Img,0,0,SD.height,SD.width,null);If you are going to ask question about your code, at least post a working code.
The code you posted contains so many syntactic and semantic errors that nobody would bother to fix. -
Resizing JFrames and JPanels !!!
Hi Experts,
I had one JFrame in which there are three objects, these objects are of those classes which extends JPanel. So, in short in one JFrame there are three JPanels.
My all JPanels using GridBagLayout and JFrame also using same. When I resize my JFrame ,it also resize my all objects.
My Problem is how should i allow user to resize JPanels in JFrame also?? and if user is resizing one JPanel than other should adjust according to new size ...
Plese guide me, how should i do this ...
Thanknig Java Community,
Dhwanit ShahHey there, thanx for your kind intereset.
Here is sample code .
In which there is JFrame, JPanel and in JPanel ther is one JButton.Jpanel is added to JFrame.
I want to resize JPanel within JFrame,I am able to do resize JFrame and JPanel sets accroding to it.
import java.awt.*;
import javax.swing.*;
import com.borland.jbcl.layout.*;
public class FramePanel extends JFrame {
JPanel contentPane;
GridBagLayout gridBagLayout1 = new GridBagLayout();
public FramePanel() {
try {
jbInit();
catch(Exception e) {
e.printStackTrace();
public static void main(String[] args) {
FramePanel framePanel = new FramePanel();
private void jbInit() throws Exception {
contentPane = (JPanel) this.getContentPane();
contentPane.setLayout(gridBagLayout1);
this.setSize(new Dimension(296, 284));
this.setTitle("Frame and Panel Together");
MyPanel myPanel = new MyPanel();
this.getContentPane().add(myPanel);
this.setVisible(true);
class MyPanel extends JPanel {
public MyPanel() {
this.setSize(200,200);
this.setLayout(new FlowLayout());
this.setBackground(Color.black);
this.setVisible(true);
this.add(new JButton("Dhwanit Shah"));
I think i might explained my problem

Problem with installing and running some applications or drivers
When installing and installing some items, towards the end of the installation I get this message:
/System/Library/Extensions/comcy_driver_USBDevice.kext
*was installed improperly and cannot be used. Please try reinstalling it or contact product's vendor for update*
The end result is that some things do not seem to work properly, such as my HP printer. Would anybody have any ideas on how to fix this problem?Thank you for your response. Originally, I had a problem with Airport and ended up reinstalling Snow Leopard. Since then, when downloading upgrades etc, such as HP printer drivers, iTunes etc., towards the end of the download when its running the script, I get this message: /System/Library/Extensions/comcy_driver_USBDevice.kext
+was installed improperly and cannot be used. Please try reinstalling it or contact product's vendor for update+
Sometimes, the download hangs and is unable to complete. The main problem I've encountered so far with an application is when I use the printer to scan an image via Preview, it's blank: there's nothing there. -
Problems with outlook and address book contacts: my outlook contacts had around 3,000 entries. Outlook duplicated entries and have now 340,000. I reinstalled microsoft office and, thus, outlook, and reinstalled mac OS X system and applications. While I managed to delete outlook contacts so that I can re-sync with my blackberry, the contacts at Mac Address Book were not deleted and still have over 340,000 entries. I do not mind deleting all contacts since I have back up, but I have not been able to delete them. Also, when I go at Address Book and try to delete or merge duplicated entries, the system takes forever and never ends because of such large amount of entries. Worse, when I do so I run out of RAM memory.
My Macbook pro is just 2 months old.
What should I do? Is there a way to delete my Mac Address Book without having the problem above?
Many thanks
