ImageIcon Border
Hi all,
I'm looking to create a white rectangular border around my ImageIcon on a JLabel, not around the Jlabel. Any suggestions would be appreciated. Thanks.
-roger
Here's something to get you started:
ImageIcon imageIcon = new ImageIcon(getClass().getResource("myIcon.gif"));
int borderWidth = 1;
int spaceAroundIcon = 2;
Color borderColor = Color.WHITE;
BufferedImage bi = new BufferedImage(imageIcon.getIconWidth() + (2 * borderWidth + 2 * spaceAroundIcon),
imageIcon.getIconHeight() + (2 * borderWidth + 2 * spaceAroundIcon), BufferedImage.TYPE_INT_ARGB);
Graphics2D g = bi.createGraphics();
g.setColor(borderColor);
g.drawImage(imageIcon.getImage(), borderWidth + spaceAroundIcon, borderWidth + spaceAroundIcon, null);
g.drawRect(0, 0, bi.getWidth() - 1, bi.getHeight() - 1);
g.dispose();
JLabel label = new JLabel("MyText", new ImageIcon(bi), JLabel.LEFT);

How can I remove the gradient background & border from an ImageIcon?
Problem1: Hey, I have a program that randomly displays a stop sign that I'm supposed to click on as fast as I can. And I created a gif with the stop sign, with it's background transparent. But when I added it to my application using an ImageIcon, whatever's supposed to be transparent in the gif is shown up as a gradient. There's also a border around the ImageIcon. Is there any way to get rid of these? Thanks
Problem 2: I also have a background for my entire application, but it stays the same size no matter if I maximize the application or run it on a different screen size. Is there any way to scale a background (it's animated), to the full screen?
Thanks again! It's for a project due tomorrow. I'm doing final touches.
Here's some of my code. It's really long, so I took out what I think is related. JButton stopSign1 = new JButton();
this.getContentPane().add(stopSign1,null);
ImageIcon stopSign = new ImageIcon("Dead_End.gif");
stopSign1.setBounds(new Rectangle(randomX, randomY, 150, 150));
stopSign1.setIcon(stopSign);
stopSign1.setVisible(false);Try stopSign1.setBorder(null);
stopSign1.setOpaque(false);Also, in future, post Swing questions in the Swing forum. -
hi, i do a program to create "business case table", but i've a problem in the 2nd part of the table, because in my 2nd table i have a JComboBox with image, when i click the combobox the images are show, but when select some figure the cell don�t keep the image, only keep the text.
Anyone can help me???

// Returning the Class of each column will allow different
// renderers to be used based on Class
public Class getColumnClass(int column)
return getValueAt(0, column).getClass();
table.setPreferredScrollableViewportSize(table.getPreferredSize());
JScrollPane scrollPane = new JScrollPane( table );
getContentPane().add( scrollPane );
public static void main(String[] args)
TableIcon frame = new TableIcon();
frame.setDefaultCloseOperation( EXIT_ON_CLOSE );
frame.pack();
frame.setVisible(true);
}If this doesn't help then post a similiar demo program that shows the problems you are having, not your entire application. -
Hi I am having a little problem with my program that I am trying to develop.
I have created a JFrame and instead of having the background the usual grey I have used an image.
I then wanted to create some nice big buttons with nice smooth curved edges but was having trouble using the JButton so decicded to use a JLabel and attach a MouseListener to it. This seems to be working fine at the mo.
The only problem is that instead of my nice gradient filled background being displayed I get a big white border around the JLabel. The rest of the background is perfectly displayed having only a problem around the JLabel. I have tried not using a background image and it shows the JLabel correctly and the button looks nice and smooth.
I think it might be something to do with the rendering sequence maybe but I am at a loss. If any one has any ideas on how to fix it or a better way of doing it I would be most grateful.
Many thanks for your help in advance.
Matt
PS now heres my code:
public class GUI extends JFrame implements MouseListener {
ImageIcon icon;
JPanel buttonPanel = new JPanel();
public GUI(){
super("Property Works - Estate Agent Management System");
icon = new ImageIcon("images/bg.jpg");
JPanel panel = new JPanel(){
protected void paintComponent(Graphics g){
//g.drawImage(icon.getImage(), 0, 0, null);
Dimension d = getSize();
//g.drawImage(icon.getImage(), 0, 0, d.width, d.height, null);
super.paintComponent(g);
panel.setOpaque(false);
addButton();
panel.add(buttonPanel);
getContentPane().add(panel);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setExtendedState(JFrame.MAXIMIZED_BOTH);
setVisible(true);
public void addButton(){
ImageIcon icon1 = new ImageIcon("images/buttons/addProperty.gif");
JLabel addProperty = new JLabel(icon1);
addProperty.setOpaque(false);
addProperty.setToolTipText("Add a new property");
addProperty.addMouseListener(this);
JLabel tester = new JLabel("Tester");
tester.setOpaque(false);
buttonPanel.add(addProperty);
buttonPanel.add(tester);
public void mousePressed(MouseEvent arg0) {
// TODO Auto-generated method stub
System.out.println("Button Clicked");
}Swing related questions should be posted in the Swing forum.
Use the "code" tags when you post code so the formatting is retained.
The code you posted doesn't compile so we can't see the incorrect behaviour.
Using code I already have I do not see any white border around the image. I tested using a "Duke" image which is found in many of the Swing tutorial examples. Maybe your image is the problem. -
Xp: bug: jbutton: transparent + no border
hi,
we have tested our swing-application under win-xp and must see that the jbuttons doesn't be shown correctly. this problem does exist only under win-xp. in win9x, winnt, win2k it works perfectly.
we use own designed buttons with transparent gif's and no borders. here is an example:
(look+feel = system)
ivjButNext = new javax.swing.JButton();
ivjButNext.setName("ButNext");
ivjButNext.setBounds(350, 5, 103, 42);
ivjButNext.setOpaque(false);
ivjButNext.setBackground(new java.awt.Color(0,100,255));
ivjButNext.setForeground(java.awt.Color.black);
ivjButNext.setIcon(new javax.swing.ImageIcon(getClass().getResource("but_1.gif")));
ivjButNext.setPressedIcon(new javax.swing.ImageIcon(getClass().getResource("but_2.gif")));
ivjButNext.setDisabledIcon(new javax.swing.ImageIcon(getClass().getResource("but_3.gif")));
ivjButNext.setFocusPainted(false);
ivjButNext.setBorderPainted(false);
ivjButNext.setFont(new java.awt.Font("Arial", 1, 12));
ivjButNext.setHorizontalTextPosition(javax.swing.SwingConstants.CENTER);
ivjButNext.setText(resLocale.getString("next"));
ivjButNext.setSelected(true);we get the following problems
1. the buttons will not be transparent. we don't know if the gif not be shown correctly or the button-background.
2. the border is still visible. the borderpainted/focuspainted-command doesn't work correctly
thx for prof. answers
oliverIt is because XP laf doesn't have the same behavior as previous Wndows laf (skins!).
if you want to have your own design change the UI for the buttons :
JButton b = new JButton("Test");
b.setUI(new BasicButtonUI());
b.setBorder(BasicBorders.getButtonBorder()); // don't forget for buttons only
JToggleButton tb = new JToggleButton("Test");
tb.setUI(new BasicToggleButtonUI());If you want to set it for all buttons:
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
catch (Exception e) {
e.printStackTrace();
UIManager.put("ToggleButtonUI", "javax.swing.plaf.basic.BasicToggleButtonUI");
UIManager.put("ButtonUI", "javax.swing.plaf.basic.BasicButtonUI");(don't forget to set also the border for the JButtons if you want it)

ImageIcons in a JLabel get their top-most row of pixels cut off
Hello. I've added a "Loading..." screen to my application that basically consists of a JWindow with a background image. However, I've noticed something odd when adding an ImageIcon to a JLabel. It seems that any image I add gets its top row of pixels cut off. The small program below illustrates this.

import java.awt.*;

}(Obviously, replace my_image.jpg with something else if you'd like to run the code on your own machine.)
When I run the program with, say, an 800 x 600 resolution image, the output I get is:
label dimensions: 800 x 599
image icon dimensions: 800 x 600As you can see, the image gets "shortened" by one pixel when added to the JLabel. If you look at the image that is displayed, you can see that it's the top row that gets cut off. I've tried changing the layout of the JWindow that the JLabel is being added to, but that didn't change anything. I've tried using a number of different images in varying formats, and the same thing happens to all of them.
Any ideas? Thanks in advance.Have you tried to set label's preferredSize manually?
What happens when you add empty border t the label with some insets?

Hello,
I've just about finished a program I've been working on for the last few weeks. But I need some help with one more thing. What I want to do is somehow build into my If and Else statements some code that will change the ImageIcon to a certain picture depending on where the click was. For instance, in my code right now I have code in place:
if (x < 200) // if the click is below 200 on the x axis
setTitle("LEFT (" + x + ", " + y + ")");
else if (x > 440) // if the click is above 440 on the x axis
setTitle("RIGHT (" + x + ", " + y + ")");
.....And such. This is just in place until I get the code in that will change the ImageIcon. I am thinking that I will need to set up an ImageIcon arrary, then have the code be something like
"if (x > 200) and ImageIcon index = 1
set ImageIcon index (4)"
and so on for the rest of the if statements. How would I go about doing this? Is there an easier way than an arrary? Is it possible to have "and" in the "if" statement? My full code is below for more info.

Quick question - JButton containing an Image - removing the Images border?
Hi, I have a JButton with an image inside it.
I would like the JButton to have a border, but not the image when it is clicked.
It currently looks like this - here
As you can see, there are two borders (this is once the button has been clicked).
The one around the JButton is the one I wish to keep, the one around the ImageIcon is the one I would like removed.
I am sure there is a simple way to do this - I'm sure I have managed it before.
part of the code used to create:
JButton money = new JButton();
money.setBackground(buttonColor);
money.setIcon(new ImageIcon ("money.gif");That thin blue box is indicating the button has focus. It appears even if the button just shows text and has no icon. Here is an example where I get rid of it on btn1 but not btn2.
And in the future, please post Swing questions to the Swing forum.
import java.awt.*;
import javax.swing.*;
public class ButtonExample {
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable(){
public void run() {
new ButtonExample().launch();
void launch() {
JPanel cp = new JPanel();
JButton btn1 = new JButton("button 1");
btn1.setFocusPainted(false);
JButton btn2 = new JButton("button 2");
cp.add(btn1);
cp.add(btn2);
JFrame frame = new JFrame("ButtonExample");
frame.setContentPane(cp);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.pack();
frame.setLocationRelativeTo(null);
frame.setVisible(true);

</center>Hello. So, it's difficult to say, but the following line is probably the cause of the problem.:
Image sourceImage = new ImageIcon(Toolkit.getDefaultToolkit().getImage(newName));Basically, you are making an ImageIcon by passing an image, but perhaps you can just replace the line with this:
Image sourceImage = Toolkit.getDefaultToolkit().getImage(newName);I use ImageIcon when reading from files, such as:
BufferedImage image = ImageIO.read(file);
Icon icon = new ImageIcon(image);However, if you already have an Image, I don't see why you just can't just use the Image reference. Perhaps someone more wise will have a more concise answer. Good luck. -
Having some problems with ImageIcons and JLabels
I'm making a checkers game, and so far it's going pretty well.
I've got the basic game down, and you can move pieces, jump, your turn ends when you can't jump anymore, etc...
However, I've had three problems:
1.) I'm using JLabels to display my board (8 x 8.. well actually 9 x 9 for an outer row labelled A,B,C,D.. 1,2,3,4...) Anyway, I create the JLabels using something that looks like \:
JLabel square = new JLabel(new ImageIcon("pic.png"));
Now, the picture loads properly, but it seems like the picture is being cropped, and the top and bottom are getting chopped off, so my 36 x 36 pixel *.gif appears to be 36 x 30.
You can see how there is a gap created in:
http://img235.imageshack.us/img235/7765/prob13ky.jpg
Now the problem may be with the GridLayout I am using, but I set the distance between the components in the container to be 0, 0 so I don't think that GridLayout is chopping my icons. I've also tried setPreferredSize(new Dimension(36,36))
for both my ImageIcons and JLabels and for my container (which I set to size 2000,2000, just to make sure there was room). If anyone can help me, it's be appreciated.
2.) I used to be able to view my outside row/column of squares that said A,B,C,D.... and 1,2,3,4... with the square in the corner having a random pic. For some reason now (have no clue why) I now see only the pic in the corner, and then a little gray smudge diagonally under it.
Pic:
http://img347.imageshack.us/img347/8308/prob24im.jpg
I don't know what's wrong. I'm pretty sure it's none of the new methods I've written, as those are all in my static void main (String[] ar) ...... and if I comment all the methods in my main except where I first make the JFrame and set it visible, it still turns out like that. repaint() doesn't help.
3.) For some reason, when I move another window (AIM, the console window, etc...) over my Swing window, it "erases" (turns gray, just wipes clean) the part where I have my squares that have pieces.
What's weird is that:
The border pieces (err.. my one visible corner piece from my second problem) don't get wiped, and some debugging text and JLabels (in a different JPanel) are fine. I don't think the JPanel matters though; the border pieces and the playing squares (which get wiped) are in the same JPanel and same array of squares.
repaint(); also erases ALL of my playing squares, whereas moving a window over them would only erase the part that the window covered.
Also, I added a mouseListener so that whenever I move the mouse over a square, it changes the image (to a tinted version, so you know the mouse is over it) and when you move the mouse away, it returns to normal. However, if I wildly swing the mouse around the area, it seems to lock up and freeze for a few seconds. Is there anything I can do to prevent this??
Thanks in advance.It is hard to tell what your problems are without any code at all (I saw your images, but that doesn't make it easy to see what is wrong in your code). If you do post code, please use code tags (see button above posting box).
I've seen your MouseListener problem before--we had the exact same issue in our code at work. It would freeze up while it processed all of the mouse events (unbearably slow). I'm not at work right now, so I don't recall how it was fixed. Essentially, you need to only process the event periodically. You need to only update the image if the mouse switches squares. Or, only update the image if the distance from the last mouse event is more than some specified amount. We might also have checked the time difference between mouse events before processing a new one. I could look at the code at work tomorrow, if you are still having trouble. -
Image button without border !!!
Hi guys
I have created a button with an image. But, the border surrounding the button is disturbing. I have written the following code :
searchButton = new JButton ("", new ImageIcon ("c:/SEClientFiles/3sr03b.gif"));
searchButton.setMargin( new Insets(0, 0, 0, 0));
searchButton.setOpaque(false);
searchButton.setBounds(540, 60, 90, 40);
p.add(searchButton);
searchButton.addActionListener(this);I just want to remove the border and have a plain image as a button. Could anyone please help me out ?
Thanks in advance.

Hi group,
You know when you start up Mozilla you get a little picture which flashes up breathing fire? I wanna make a frame do that! I've got it so it flashes up a picture for 3 seconds and disposes of itself. From the main application it is run as a thread. I run it by calling
new showflash().
Here is the code ...
import java.awt.*;
import javax.swing.*;
import java.awt.geom.*;
public class Flashpan extends JPanel {
private ImageIcon m_icon;
public Flashpan () {
JFrame frame = new JFrame("Border Title Bar");
frame.setSize(669, 525);
Container content = frame.getContentPane();
content.add(this);
m_icon = new ImageIcon("image.jpg");
/*flash the window*/
frame.setVisible(true);
/* 3 second delay */
try {
Thread.sleep(3000);
} catch (InterruptedException e) {
/*kill the window*/
frame.setVisible(false);
frame.dispose();
public void paintComponent(Graphics g) {
super.paintComponent(g);
Graphics2D g2d = (Graphics2D) g;
m_icon.paintIcon(this, g2d, 10, 10);
public static void showflash() {
new Flashpan();
Now the question is How do I make the window borders disappear. I have only one object contained in the frame, the picture. I want everything to disappear without killing it except this picture object? How do I do it? Im sure many people must have done this!! Maybe my code sucks.. pls forgive me :P
Ive been looking at Inset() BorderLayout() etc.. etc.. but cant seem to work it out or find an example. I thought maybe it was frame.Inset(0,0,0,0) but I was wrong.Bingo, Ta for that....
Complete code is as follows (screen centers now)
import java.awt.*;
import javax.swing.*;
import java.awt.geom.*;
public class Flashpan extends JPanel {
private ImageIcon m_icon;
public Flashpan () {
JWindow frame = new JWindow();
frame.setSize(640, 480);
/* Get the size of the screen */
Dimension dim = Toolkit.getDefaultToolkit().getScreenSize();
/* Determine the new location of the window */
int w = frame.getSize().width;
int h = frame.getSize().height;
int x = (dim.width - w) / 2;
int y = (dim.height - h) / 2;
/* Move the window */
frame.setLocation(x, y);
Container content = frame.getContentPane();
content.add(this);
m_icon = new ImageIcon("image.jpg");
/*flash the window*/
frame.setVisible(true);
/* 3 second delay */
try {
Thread.sleep(3000);
} catch (InterruptedException e) {
/*kill the window*/
frame.setVisible(false);
frame.dispose();
public void paintComponent(Graphics g) {
super.paintComponent(g);
Graphics2D g2d = (Graphics2D) g;
m_icon.paintIcon(this, g2d, 0, 0);
public static void showflash() {
new Flashpan();

Jtable Header's border disappear after placing an icon on it
I tried this in java 1.4
it works fine but the border between the headers of my JTable diappear
Anyone knows why?
ImageIcon icon = new ImageIcon(pathoficon);
DefaultTableCellRenderer headerRenderer =new DefaultTableCellRenderer();
headerRenderer.setIcon(pathoficon);
TableColumnModel colmod = jtable.getColumnModel();
colmod.getColumn(col).setHeaderRenderer(headerRenderer);
jtable.getTableHeader().resizeAndRepaint();Its because DefaultTableCellRenderer isn't quite the mustard for a header renderer. Mine is shown below, the crucial line being setBorder(UIManager.getBorder("TableHeader.cellBorder"));
private class SortHeaderRenderer extends DefaultTableCellRenderer
RenderInfo r_;
SortHeaderRenderer(RenderInfo r)
r_ = r;
public Component getTableCellRendererComponent(javax.swing.JTable table,
Object value,
boolean isSelected,
boolean hasFocus,
int row,
int column)
if (table != null)
JTableHeader header = table.getTableHeader();
if (header != null)
setForeground(header.getForeground());
setBackground(header.getBackground());
setFont(header.getFont());
setText((value == null) ? "" : value.toString());
setBorder(UIManager.getBorder("TableHeader.cellBorder"));
setHorizontalAlignment(SwingConstants.CENTER);
setHorizontalTextPosition(SwingConstants.LEFT);
// Check if we are the primary sort column and if so, which
// direction the sort is in
if ((orderItems_ != null) && (orderItems_.contains(r_)))
if (sortDescending_)
setIcon(sortDescending__.getIcon());
else
setIcon(sortAscending__.getIcon());
else
setIcon(null);
return this;
}Never mind about anything else because that's specific to me. -

} Edited by: 87654321 on 07-Sep-2011 06:12Don't use a GridLayout for the content pane of the frame. The GridLayout makes all components the same size.
Use the BorderLayout which is the default layout for a frame anyway.

//add(p2);
//add(p1);

Border not rendering properly on JPanel
This is just a general question to see if I'm the only one having this problem or whether it is just a bug.
I've got a Jframe with a couple of Jpanels within it. I want a border round one of the panels but for some reason the border only shows fully around 3 edges and only partly along the edge adjacent to the other JPanel.
I thought this might be a layering problem with the panel without the border being placed on top of the border itself but I've had a similar problem with some JTextField. I've got 3 JTextFields in a JPanel each having their own border but every now and again the border will disappear from around the bottom JTextField.
I realise this may well be a problem specific to my system or OS (Win 2000) but I thought I'd just check.
Thanks, ClarkieThanks for replying so quickly. Here is a cut down version of my code. I appologise now for using NetBeans as I believe this is frowned upon by many users of these forums.

}Also, I sometimes get a diagonal line going from the top left corner of a container to the first element when the JFrame is resized or reloaded from the Taskbar.
