i have created a simple app in java to show a tray icon and from there show a list of JIRA issues that are assigned to me.
what i have at the moment is a tray icon that when you right click on it brungs up a popup message with the last 10 open issues assigned to me, when you click a menu item it directs you to the desired issue in your browser of choice.
What i would now like it to do is display a badge over the top of the tray icon that shows how many open issues i have. i have the code to find the number of issues but i cant for the life of me work out how to add the badge to the tray icon.
im using :
java.awt.MenuItem;
java.awt.PopupMenu;
java.awt.SystemTray;
java.awt.TrayIcon;
to create the tray icon and popup menu.
any help would be greatly appreciated
Thanks
Okay so i figured it out,
first i select the original icon:
BufferedImage im = ImageIO.read(Systray.class.getResource("icon.gif"));
then i use Graphics2D to draw ontop of the image:
Graphics2D g2 = im.createGraphics();
g2.setColor(Color.BLACK);
g2.drawString("10", 2, 10);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
ImageIO.write(im, "png", baos);
byte[] b = baos.toByteArray();
then i create a new image icon from the byte array:
ImageIcon imgTmp = new ImageIcon(b);
finally i set the tray icon:
_icon.setImage(imgTmp.getImage());
(_icon is an instance of TrayIcon)
i hope that this helps someone else and if you have a better solution id love to see it

I'm doing a program to create a die (cube) with different image textures based on the input of the user (user choose images on a SWT GUI).
Once the user choose the images, it can visualize the dice on a separate dialog, and perform some rotate operations over it (see, after perform a small rotation to see three faces in the screenshots).
See screenshots: http://pastebin.com/XqJfXL6i
And my problem starts here: I want to save the content of the canvas (the dice with the background in its current form, after being rotated). I've been searching for several codes and I think that my problem is because my current canvas is an "on-screen" canvas and I need an off-screen canvas, which will allow to save the content.
My current code is the following:
http://pastebin.com/ZAv0ATJN
And.. here starts the problem. It throws this exception:
java.lang.IllegalStateException: Canvas3D: Not in off-screen mode
Concretely it fails in this line:
ImageComponent2D ic2d = canvas.getOffScreenBuffer();
As you can see there are several lines commented that I tried before, but they didn't work neither.
Any clue about how to do it?
Thanks!
Based on the comment provided by gouessej (thanks!) finally I use this code, which works fine for my doubt:
private void saveImage(String img) throws Exception {
FileOutputStream fileOut = new FileOutputStream(img);
Robot r = new Robot();
BufferedImage bi = r.createScreenCapture(new java.awt.Rectangle(
(int) frame.getLocationOnScreen().getX(), (int) frame
.getLocationOnScreen().getY(), frame.getBounds().width,
frame.getBounds().height));
ImageIO.write(bi, "jpeg", fileOut);
fileOut.flush();
fileOut.close();
}
I need to change the Jdialog box title bar icon. By default it uses a java coffee image.
I have searched in internet and used many codes
1. Image im = Toolkit.getDefaultToolkit().getImage("/org/qmon/generate/Images/JDialog -2.ico");
dialog.setIconImage(im);
2. Toolkit kit = Toolkit.getDefaultToolkit ();
Image img = kit.getImage ("/org/qmon/generate/Images/Create File Tag-16x16.png");
dialog.setIconImage(img);
nothing works properly.. Kindly help me.. Thanks in Advance
Firtsly, ico is not a support image format for Java.
The likely reason you're having issues with the second approach is that getImage is expecting a file reference and the image you seem to referencing looks like it's embedded (stored within your application)
Try using something more like...
Image img = kit.getImage (getClass().getResource("/org/qmon/generate/Images/Create File Tag-16x16.png"));
Instead.
Personally, I prefer ImageIO.read as it throws a IOException when something goes wrong...
Image img = ImageIO.read(getClass().getResource("/org/qmon/generate/Images/Create File Tag-16x16.png"));
But that's me...
You should also consider taking a look at Convert List<BufferedImage> to Image which demonstrates the use of ico file (from a 3rd party API) and setIconImages method
Image image = ImageIO.read(new URL(
"http://www.gravatar.com/avatar/f1d58f7932b6ae8027c4e1d84f440ffe?s=128&d=identicon&r=PG"));
dialog.setIconImage( image );
dialog.setVisible(true);
I am using this in my application and working fine
java.net.URL url = ClassLoader.getSystemResource("res/java.png");
ImageIcon icon = new ImageIcon(url);
JOptionPane.showMessageDialog(null, jep, "UroSync",JOptionPane.INFORMATION_MESSAGE, icon);
To improve what MadProgrammer has said, I met the problem and I solved it instantiating a JDialog but using the static class Toolkit method getDefaultToolkit().getImage(Image img).
JDialog dialog = new JDialog();
dialog.setIconImage(Toolkit.getDefaultToolkit().getImage(MyMainClass.class.getResource("/myIcon.png")));
To do that you need to add before the image into the build path of the Project.
I am using GifDecoder to read an animated .gif file and AnimGifEncoder to write it. (link)
If I display the original frames read by GifDecoder they display correctly and are transparent, but if I display the frames created by AnimatedGifEncoder the transparency is all wrong.
GifDecoder gif = new GifDecoder();
gif.read("image.gif");
AnimatedGifEncoder e = new AnimatedGifEncoder();
e.start("newimage.gif");
e.setTransparent(Color.BLACK);
for (int i=0;i<gif.getFrameCount();i++) {
anim.addFrame(gif.getFrame(i));
anim.setDelay(gif.getDelay(i));
}
anim.finish();
In this example I set the transparent color to black. But actually I want to get the transparent color information from the GifDecoder but I don't know how.
I'm using the following solution, although there are still some gif files that
are a mess after scaling... :
(At least it seems to get along with most non-transparent gifs)
Color transparentColor = null;
BufferedImage firstFrameImage = ImageIO.read([sourceFileHere]);
if (firstFrameImage.getColorModel() instanceof IndexColorModel) {
IndexColorModel cm = (IndexColorModel) firstFrameImage.getColorModel();
int transparentPixel = cm.getTransparentPixel();
transparentColor = new Color(cm.getRGB(transparentPixel), true);
}
e.setTransparent(transparentColor);
This was all a long time ago, but I did manage to get it working at the time. Without digging out the code again... I got it working by:
Scan the original image and set the transparent areas to a colour that does not exist inside the original image.
Set the transparent colour inside the AnimGifEncoder to the colour that was previously assigned to the transparent areas.
I have the following code to make a custom looking JButton
ImageIcon icon = createImageIcon(
CommonUtils.class.getClassLoader().getResource("images/wright.png")
);
RightSlide.setIcon( icon );
ImageIcon icon2 = createImageIcon(
CommonUtils.class.getClassLoader().getResource("images/right_selected.png")
);
RightSlide.setPressedIcon( icon2);
RightSlide.setSelectedIcon(icon2);
RightSlide.setRolloverEnabled(true); // turn on before rollovers work
RightSlide.setRolloverIcon(icon2);
RightSlide.setBorderPainted(false);
RightSlide.setFocusPainted(false);
RightSlide.addActionListener(new ActionListener(){
The code generates a custom button. The button behaves as expected when hover over, pressed, clicked, and selected. This works on MacOS and Linux (Ubuntu). But the same code has a light blue background on Windows. Where does this come from and how do I get rid of it ?
Thanks
I think that you missing JButton#setContentAreaFilled(false); example here
I cannot get this to work so I thought it might be a wise idea posting over here...
I have a context menu in SWT (actually its an Eclipse plugin). It's a cascaded menu, so it expands as soon as you hover over a certain entry...
My problem is, that I want to attach a small icon to the menu but I struggle with that!
Code:
....
manager.add(new Separator());
// icon for the "change color" menu
ImageDescriptor icon = ImageDescriptor.createFromFile(null,
"icons/palette_brush.png");
// submenu
MenuManager colorMenu = new MenuManager("Menu", icon, null);
// Actions
colorMenu.add(someAction);
// add the action to the submenu
manager.add(colorMenu);
....
My problem is, that the new MenuManager can either be called with 2 Arguments (no attached image) or 3 (with attached image). The image should be passed along as ImageDescriptor.
The question basically is:
"How can I get an Imagedescriptor off an image?"
Maybe it's an stupid mistake - but I cannot get an ImageDescriptor from an image file. I have an *.png icon ready to use, but I struggle incorporating this.
If anyone could help out with a snippet, that would get me an ImageDescriptor from an image file this would be soo awesome!
Best regards!

Bundle bundle = Platform.getBundle(pluginId);
URL fullPathString = BundleUtility.find(bundle, "icons/palette_brush.png");
ImageDescriptor.createFromURL(fullPathString);
pluginId is the id of the plugin where you put your icon.
Bundle bundle= org.eclipse.core.runtime.Platform.getBundle(pluginId);
URL fullPathString = bundle.getEntry("icons/palette_brush.png");
desc= ImageDescriptor.createFromURL(fullPathString);
desc.createImage();
