Coordinates on jlabel

hi, was wondering how to return the coordinates of a mouse click event on an image on jLabel. well, my code does do that, but when i change the window size, the coordinates change as well, i need to know the coordiantes of the pixel of the image in the jLabel inside a panel :o(

thanks, that looks mighty helpful, but even after reading the API, i couldn't figure out what the "destination" would be, the source would be the JPanel components, but for destination what I want is for it to be the exact size as that of the image, if you know what i mean

Setting absolute coordinates of a JLabel

Is it possible to set absolute (x,y) coordinates using JLabel? Thanks a bunch!

Positioning problems

Is there anyway to specify the coordinates for JLabels and buttons? Here is some code I am working on right now:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
public class Tutorials extends JApplet implements ActionListener
FlowLayout flow = new FlowLayout();
private Button but1, but2, but3, but4;
JLabel titleBar = new JLabel("Tutorials");
Font defFont = new Font("Verdana", Font.PLAIN, 14);
public void init()
Container con = getContentPane();
con.setLayout (new FlowLayout());
titleBar.setFont(defFont);
con.add(titleBar);
con.add(greet);
but1 = new Button("Tutorial 1");
con.add(but1);
but2 = new Button("Tutorial 2");
con.add(but2);
but3 = new Button("Tutorial 3");
con.add(but3);
but4 = new Button("Exit HTML Tutorials");
con.add(but4);
etc...
I would like to specify where everything goes, labels, buttons, textfields, etc...
Also, how would I open new "windows" using these buttons? And how would I close them using a button in the newly opened windows? Would I need different classes for each of the different windows or could I use methods inside my class file?
(Sorry if this seems remedial, but I am not good with programming in general and I am hoping this is my last programming class.)
Thanks a bunch,
Eros

import ...
class ... extends JFrame {
setBounds(12, 34, 234, 432);
getContentpane().setLayout(null);
JButton jb = new JButton("jbutton");
jb.steBounds(11, 22, 33, 22);
getContentpane().add(jb);
setVisible(true);
BTW, that question has been covered in this forum allready some time ago. google for absolutlayout

I just want to set my Jlabels coordinates, how hard can that be???? HELP

Please help

hey, basically this is the first time ive ever
touched java therefore bear with me. Basically all i

i want it to be. i want the image to stay there
permently.Two options.
Option A:
Use a null LayoutManager for your JFrame and explicitly set the bounds of the JLabel:
frame.setLayout(null);
image.setBounds(x,y,w,h); // x,y,w,h are calculated by you somewhere else
frame.add(image);Option B:
Paint the image on the JFrame directly by overriding its painting code.
Neither option is a good idea. What exactly are you trying to create?

How to get coordinates of components. PLEASE HELP ME URGENT!

Hi, I am trying to get the coordinates of my components that are tabbed pane buttons, buttons, text fields etc so I can place an image of a pointer under it that points to it and then under the image of the pointer I would put a label describing the button for example "press the tab to start". Then when I press tab1 the image of pointer image points to the next component and has a label under pointer.
Now I have tried using componenet.getX() and getY() and then set the values of the the image panel to use then the label panel so they be placed under the component, these panels are not using layout manager but absolute positioning. If the window is resized then the labels and image of pointer should also adjust. I have tried putting the label and arrow into a glasspane and now layerdpane as some people here suggested which when I do then add it to contentpane the main panel with the components is not there but the layerd pane is.
I am having huge difficulties with this and if someone can Please just tell me or even better give me an example code how to find out the coordinates of components so I can place my image of pointers and labels underneath them I will be very grateful of you. I am on a verge of giving up accomplish what I am doing and I am new to the swing framework. My progress to solve this has been very slow and frustrating. I just hope someone here can help.

I tried the both of codes given. But the code given by both the person i have not understand. And what they there code is doing. This is the code form my side if this example help u.

Set location for the JLabel

Hello!
I've got an interesting effect and I don't have a list idea why it happens. I set layout to null in the panel and created some JLabels in this panel. Then I saved locations of the labels in a data base, exited from the window and tried to create the panel and labels again using information saved in the data base. All labels appeared in the panel but their locations were slightly different in spite of the coordinates were the same as befor. The top left corner of each label slightly displacemnts to the up and left. I used setLocation method in the JLabel and also tried to use setBound but result was the same.
Does anybody know what the matter is?
TIA

you can use HelpBroker.setLocation and HelpBroker.setSize, but both are new methods introduced in JavaHelp 2.0 beta release only.

Setting JLabels to be on top.

I'm making a Deck Card that shuttle and sorts the card. I was able to display the images using a JLabel with ImageIcon. I can get to display the images and everything, but my only problem is when i'm display the image that the first image is on top of the second and the second is on top of the third.
I want it to display the opposite order so I want the first one to be under the second and the second to be under the third.
Is there a way that I can get the a label to be on top of the other?
I forgot to mentioned that they have different X and Y Coordinates.

Actually in any panel etc you have a layout which layouts the componsnts in his own way. So you need a layout that displays components as they are.
Try running following code:
import java.awt.*;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.border.LineBorder;
public class LayoutPanel extends JPanel {
   public LayoutPanel() {
      setLayout( new EmptyLayout( new Dimension( 400, 300 ) ) );
      JLabel[] labels = new JLabel[10];
      for( int i = 0; i < 10; i++ ) {
         labels[i] = new JLabel( "Label " + i );
         labels.setVerticalAlignment( JLabel.TOP ); // show text at top position
labels[i].setLocation( 13 * i, 13 * i ); // set location
labels[i].setSize( new Dimension( 100, 100 ) ); // set size
int colour = i + 10;
labels[i].setBackground( new Color( 9 * colour, 10 * colour, 11 * colour ) );
labels[i].setBorder( new LineBorder( Color.black, 1, true ) ); // set border
labels[i].setOpaque( true ); // set to draw its all pixels
add( labels[i], 0 ); // set at top means last on top, otherwise use add(labels[i]) to set first on top
public static void main( String argv[] ) {
JFrame frame = new JFrame( "Polygon Demo" );
LayoutPanel layout = new LayoutPanel();
frame.setContentPane( new JScrollPane( layout ) );
frame.pack();
frame.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
frame.setVisible( true );
class EmptyLayout implements LayoutManager {
private Dimension size = null;
EmptyLayout( Dimension size ) {
this.size = size;
public void addLayoutComponent( String name, Component comp ) {}
public void removeLayoutComponent( Component comp ) {}
public Dimension preferredLayoutSize( Container parent ) {
return size;
public Dimension minimumLayoutSize( Container parent ) {
return size;
public void layoutContainer( Container parent ) {}

ImageIcon Array and a JLabel

Hey,
I have an ImageIcon arrary and JLabel called ImageLabel on which the ImageIcon is. Bascically I want it to do this: if the ImageIcon on the ImageLabel is a certain icon, say [0] and the click was < 200, then set the ImageIcon to [1] (in effect changing what image is shown on the ImageLabel). And vice versa, as demonstrated by the following code:
if (x < 200) and (ImageIcon theIcon = [0]) // if the click is below 200 on the x axis and theIcon is [0]
setImageLabel.setIcon(ImageIcon[1]);if (x > 200) and (ImageIcon theIcon = [1]) // if the click is above 200 on the x axis and theIcon is [1]
imageLabel.setIcon(ImageIcon[2);
However that code doesn't work. What code would work?

Thank you for your reply. I tried using the code, however, I am unsure as to how to use a 2D array.
I think it may help if I elaborate on what I need to do:
I have 80 images, and would like each image to be assigned to a coordinate, such as 1,1 on a coordinate
plane that is 16 wide by 23 high. My first idea would be that you will need (16 * 23) = 368 images, not 80.
By having each image as an integer, I could then set it to load another image when clicked.
For instance I want the program to load with the image set to 1,1 (this image
would be "images/1-1.gif".)
Now, since you are on 1,1 and click on a certain area of the image, it loads 2,1 (that co ordinate having the image "images/2-1.gif". If you click on a different part of the 1,1 image, it would load 3,1 ("images/3-1.gif). etc.
Sorry to say it, but you're still unclear on your goal: will you be only displaying one image at a time ? Do you expect 1 image
to represent each of the (16 * 23) coordinates ? Do you mean that the label will change location depending on the mouse clicks ?
Whatever your objective is, I don't see what is incompatible with the code I suggested in my previous reply.

Map coordinates in MapViewer

Hi,
I have a Java application that submit requests to MapViewer. MapViewer4s response is a XML document, something like:
<?xml version="1.0" encoding="UTF-8" ?>
<map_response>
<map_image>
<map_content url="http://map.oracle.com/output/map029763.gif" />
<box srsName="default">
<coordinates>-122.260443,37.531621 -120.345,39.543</coordinates>
</box>
<WMTException version="1.0.0" error_code="SUCCESS"/>
</map_image>
</map_response>
Thus, what I do is using a JLabel to show the image in the URL returned by MapViewer.
All of this is working fine. Now I4m trying to make something more complicated.
What I want to do is caught the user4s mouse click in the image and translate the point in which the user clicked (pixels) to a point in the map coordinates (longitude, latitude).
How can I do this ? What API may I use ?
Thanks,
Rodrigo

The <BOX> element in the XML map response gives you the bounding box of the returned map image, in user's coordinate space.
Now you can get the mouse click's x,y in terms of pixels, and you also know the map image's width/height in terms of pixels. It should be easy to translate the click's position into user space.

Image coordinates in JPanel

Hi everyone,
I need help in getting coordinates of a image that I have loaded in a JPanel using JFileChooser. The file is on my computer and that it can be any image. With the just loaded image, i have positioned it at 0,0 using the g.draw(). I will be dragging the image around the panel and I have seen some other people using certain methods to drag the image around the panel. Lets say the image img = null;
I have tried img.getX(), img.getY() or
img.getLocation.x, img.getLocation.y, or
img.x, img.y or
but the compiler give me "Cannot resolved symbol" for all the above methods or maybe some of the methods but the point is, none of the above methods work. Did miss out something or do i have to include some class or something?
The reason i need to get the x,y for my image is to allow me to drag it around the panel. What i am looking for is to get the image coordinates x,y on the panel. As in the location of the image in the panel.
Thanks in advance for the help.

looking for is to get the image coordinates x,y on the
panel. As in the location of the image in the panel.There are two common ways to do this:
1. Your custom panel directly drawing the image, so it has the job of knowing the image's position.
Why not make imageX and imageY fields of your panel class?
2. You custom panel class works like a Container, withe the image(s) being managed by a JLabel.
Then your panel will use a null LayoutManager or perhaps will be a JLayeredPane and the JLabel's
location is the location of the image.

Getting coordinates

Hello group,
I have a Container, containing various JComponents, and one of them is a JScrollPane containing a JLabel, and the JLabel contains an Image.
When I click on the image, how to get the (x,y) relative to the origin of the image ?
I make the JLabel listening to MouseClicks, but I that way I get translated coordinates.
Sorry, the question is elementary, but my various attempts failed.
Many thanks

Problem setting ImageIcon onto JLabel

Hi guys I am currently writing a Pente board game.
Now I have two classes called Stone and GameStatus.
In the GameStatus constructor it basically generates a JPanel and I try to fill it with 19 x 19 JLabel and add a mouselistener to each of them. This way when the label gets clicked, I can change the Image of it to represents empty spot, with white stone or with black stone.
Here is the code of Stone class
package pente;
import javax.swing.*;
public class Stone extends JLabel
// the color of the Stone object
private String color;
private int x, y; // the location of current Stone
boolean occupied; // see if the spot is occupied
// the location of each image file
private final String EMPTY = "c:/empty.jpg";
private final String BLACK = "c:/black.jpg";
private final String WHITE = "c:/white.jpg";
// private JLabel label = new JLabel();
* The default constructor that initializes a
* Stone object with a given color.
public Stone(int x, int y, boolean o, String c)
      this.x = x;
      this.y = y;
      this.occupied = o;
      this.color = "empty"; // the color has not yet been set
      this.setIcon(new ImageIcon(EMPTY));
    // assign the given color to the Stone
   * This method sets the image of the current object depends on
   * the given variable c.
   * @return the Stone object with an appropriate image on it
public Stone setColor(String c)
      // swtich the image of the Panel depends on the c given
      if ((c.equals("w")) || (c.equals("white")))
        this.color = "white";
        this.setIcon(new ImageIcon(WHITE));
      else if ((c.equals("b")) || (c.equals("black")))
          this.color = "black";
          this.setIcon(new ImageIcon(BLACK));
      return this;
   * This method replaces the current image with the empty image
   * @return the Stone object with empty image on it
public Stone setEmpty()
      this.color = "empty";
      this.setIcon(new ImageIcon(EMPTY));
      return this;
   * This method gets the x coordinate of Stone
   * @return the x coordinate
public int getX()
      return this.x;
   * This method gets the y coordinate of Stone
   * @return the y coordinate
public int getY()
      return this.y;
   * This method tests if the current Stone has been set to a color
   * @return if the Stone has been set to a color
public boolean isOccupied()
      return (!(this.color).equals("empty"));
}Here is the part where GameStatus calls Stone class
public GameStatus(int size)
        this.setTitle("PENTE");
        this.setLocation(100,30);
        this.setSize(747,695);
        this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        JPanel p = new JPanel();
        p.setLayout(new GridLayout(0, size, 0, 0));
        // initializes the array and starts inserting labels
        for (int i = 0; i < size ; i++)
            for (int j = 0; j < size ; j++)
                array[i][j] = new infoArray(i, j, false, EMPTY);
                Stone s = new Stone(i, j, false, EMPTY);
                s.addMouseListener(new MousePressListener());
                p.add(s);
        this.setResizable(false);
        this.getContentPane().add(p);
        this.setVisible(true);
        System.out.print("hello");
    }The problem is, there is only one Stone object can be shown on the JPanel.
This is weird since it works fine when I tried to call JLabel object instead of Stone object and fill them into JPanel.
Since Stone class extends JLabel, I just dont see why JLabel works while Stone doesn't.
I need to know the reason badly, so I appreciate any suggestions.
Thanks.

Code looks reasonable. Only comment I have is that icons can be shared by multiple components. So you only need to create 3 icons, one for each state of the stone. Then you just use setIcon to change the state. No need to recreate the icon every time.

Painting coordinates problem

hi,
i have noticed that when i put a picture like a JLabel in Jpanel the coordinates for the picture start from the left upper corner meaning:
(0,0)
-------------->x
|
| picture
|
v
y
how can i rotate the coordinates so it will b that y is facing up and x remain as it is?
thx.

thx, but that wasn't what i meant,
when im painting in a picture using the repaint() method,
if for example i want to draw an oval in (0,0),
the oval will b shown in the upper left corner of the picture but i want it to b drawn in the lower left side of the picture with the same coordinates (0,0),and 4 that i need to rotate the picture coordinates somehow,
the g.rotate() wont help because even if i rotate i will never b able to rotate it like i want in my first post(or i could b wrong?),
thx anyway.

Display priority for JLabel

Hi.. I have a program that will be displaying a lot of JLabels with ImageIcons.
In many cases throughout the program, JLabels will overlap or take the same coordinates as another JLabel. At any given coordinate, my intention is to give a specific JLabel priority for display over another - displaying its contents and underneath it, the other JLabel(s) would display theirs.
I was wondering if there was some way of determining and setting which JLabel had priority for display. I noticed that by default it depends on the order in which they are added to a container. Is there another way of changing this, especially if they are already inside a container?

In JDK1.5 and later versions I believe a new method to set the Z-order has been added.
Prior to JDK1.5 you would need to use a JLayeredPane.
