Java Swing and windows listview control

Hi,
many programming languages have the listview control, to which you can define diferents kinds of data's organizers as Icon, Detail, List, etc.
Somebody knows if java swing have a component as the listview ?
thanks

Yes. It's called JList. Have a look at the tutorial:

Java Swing and WIndows User Localles

HI,
We need to develop a java applet/application which can be switchable at run time to accept and display characters in multilanaguages. This java applet will run on a windows 2000 server with multilanguage pack installed. Is it possible to dynamically switch languages at run time. The machines default localle and operating system installation is US English.
We have tried some tests with traditional chinese and UI components in Swing but with no success in displaying or inputing valid chinese characters. Has anyone attempted a simliar thing and have any insights that may help.
Thanks in Advance,
Jono

Performance issue Java Swing under Windows 7

Hello,
we have MDI Java Swing application running under Window7. We got a big problem with performance in MDI Windows using AERO.
Exist any way for Java to tell Win7 that it should not use Aero??
Thank you,
David.
Edited by: 969767 on 6.11.2012 3:33

If you try to open properties dialog for application (or app shortcut) there you can see "Compatibility" tab and there is check box "Disable visual themes". If we disable this theme our java swing app is very better performance under Windows 7. We need to disable visual theme via java code, if it is possible...
Thanks.

Swing and windows system tray

could anyone please tell me whether it is possible to have a java swing application running on a windows machine, minimise into the system tray?
Thank-you.

AFAIK no. This is because the system tray is rather platform specific. I believe it is possible to have your app tuck itself neatly away in a corner of your desktop, and obviously you can minimise to the task bar. However without soem kind of native addition (maybe a custom launcher?) you can't minimise to the system tray.
Sorry
:-(

Java Swing and Flash

Is it possible to create flash components (swf files) and include them in a Swing JFrame and be able to post data from and to it.
For example, if the swf gui is showing a list of items, the list is coming from the Java application and then the SWF file gets included in a Swing JFrame. When user chooses an item from the list and clicks a button then the results is passed back to the Java application.
Has anyone done something similar to this? How is this possible? Code samples would be appreciated.

May be you can try out JFlash ...
https://jflash.dev.java.net/
They support only upto Flash 2 player... and it is still under development i guess...

Java Swing and Socket Programming

I am making a Messenger like yahoo Messenger using Swing and Socket Programming ,Multithreading .
Is this techology feasible or i should try something else.
I want to display my messenger icon on task bar as it comes when i install and run Yahoo Messenger.
Which class i should use.

I don't really have an answer to what you are asking. But I am developing the same kind of application. I am using RMI for client-server and server-server (i have distributed servers) communication and TCP/IP for client-client. So may be we might be able to help each other out. My email id is [email protected]
Are you opening a new socket for every conversation? I was wondering how to multithread a socket to reuse it for different connections, if it is possible at all.

Java swing and threading issue

i am trying to update swing components from some thread. at my first try, i noticed this was a disaster. upon further research, i found out about the single-threaded model of swing events (i.e. event dispatching thread).
i did more research and could NOT find a good example on how to update swing components from other threads. many examples were showing too much.
can someone post a simple example on here? i just want to see how to properly update a swing component from a non-swing class using threading.

I think its a simple example:

Let us know what you think.

Wrong image refresh in java applet AND Windows 7

I'm managing since few days a java applet that takes an image from an industrial product and shows it in a browser (simple web server).
There is following issue: the image is not correctly loaded and refreshed in its own window if just opened but only if the applet is running on Windows 7. The issue is solved as soon as I reduce the window to icon (minimize) and then resize it. I'm looking into java documentation on how to manage the image rendering, maybe I have to override some update or redraw method more, but it is taking time and I'm still learning. NOTE that the window opened does show the issue only when the windows size is not completely shown in the monitor.
Meanwhile I'm wandering if some of you faced and solved similar problem.
Thank you in advance,
Elena

Thank you Nitin for your quick reply!
These are the calling of the functions in the code. As you can see, before to show the image, we are managing a zoom/unzoom by mouse wheel and an addition of writings data on the image itself. All is working fine except on W7:
public void paint(Graphics g)
     //System.out.println("[ImageFrame::paint my paint!!!]");
     this.PaintImage(g);
public void update(Graphics g)
     // System.out.println("[ImageFrame::update]");
     this.repaint();
public void PaintImage(ImageInfo imageInfo, float fps)
     if (imageInfo != null)
          if (this.getImageInfoRef() == null){
               this.setVisible(true);
          this.setTitle("Image Viewer (" + imageInfo.bufferedImage.getWidth() + "x" + imageInfo.bufferedImage.getHeight() + ") ");
          this.resizeImageFrame((int) (imageInfo.bufferedImage.getWidth() * zoomFactor), (int) (imageInfo.bufferedImage.getHeight() * zoomFactor));
          this.lastFps = fps;
          this.setImageInfoRef(imageInfo);
          //System.out.println("this.getWidth(): " + this.getWidth() + " this.getHeight(): " + this.getHeight() + " zoomFactor: " + zoomFactor);////
          this.PaintImage(this.getGraphics());
public synchronized void PaintImage(Graphics g)
     ImageInfo locImageInfo = getImageInfoRef();
     if (locImageInfo != null)
          try
               this.resizeImageFrame((int) (locImageInfo.bufferedImage.getWidth() * zoomFactor), (int) (locImageInfo.bufferedImage.getHeight() * zoomFactor));
               BufferedImage bufferedImage = this.resizeBufferedImage(locImageInfo.bufferedImage, zoomFactor);
               this.overlayCodeInfo(bufferedImage, locImageInfo.decInfoStruct, zoomFactor);
               this.overlayPointerInfo(bufferedImage, locImageInfo.scaling, zoomFactor, this.crossX, this.crossY);
               this.overlayFrameRateInfo(bufferedImage, this.lastFps);
               Image img = Toolkit.getDefaultToolkit().createImage(bufferedImage.getSource());
               boolean retdraw;
               retdraw = g.drawImage(img, frameUpperBondarySizeX, frameUpperBondarySizeY, this);

Java, Cygwin, and Windows.... oh my.

So the problem can be summarized as follows. I have a call out to the operating system from Java to obtain the value of vmstat which returns a value from every x seconds based on the refresh rate. To do This I use a command similar to this
Runtime rt = Runtime.getRuntime();
String[] comm = new String[] {"vmstat","1"};
Process proc = rt.exec(comm);
I can then loop around capturing the output and parsing it. Simple.... This approach works on Linux, Mac OS, HP-UX, AIX and Solaris however it fails under Windows. It sits there and simply waits. Now this appears to be a common problem based on the number of postings on it. This article(http://www.javaworld.com/javaworld/jw-12-2000/jw-1229-traps.html) suggests a number of approaches to solve the problem. Ive tried them all and the good news is that they appear to work for a single atomic call that returns all of its output then exits. However commands such as vmstat/iostat/sar etc. return output periodically based on their refresh rates and dont seem to work at all.
There are plenty of hits in google but no one really seems to suggest a solution. Now Im sure this worked in the past and Im almost certain that I havent changed the code.
Ive tried calling
java myexec cmd /c "c:\\cygwin\\bin\\ls.exe"
Which returns the first line of the directory and then exits.
java myexec cmd /c "c:\\cygwin\\bin\\ls.exe"
simply hangs.... whilst
java myexec cmd /c dir
Works fine.... So my believe its the combination of java and cygwin and the way io is redirected. If anyone has a chance to look at it.... Ill be very grateful. Code for simple testcase below.

Apologies for the code tags.... now included below

+Which returns the first line of the directory and then exits.+
+java myexec cmd /c "c:\\cygwin\\bin\\ls.exe"+

should read

*java myexec cmd /c "c:\\cygwin\\bin\\vmstat.exe*"

I agree with the comments about the quality of the example.... it was a quick and dirty hack. It dosen't take away from the issue that it works on every combination except windows and cygwin....
Any other thoughts?

Java Swing and Microsoft Excel

How do you open a Microsoft Excel file from swing?
please give a example.

Hi,
try these APIs:
[http://poi.apache.org/]
[http://jexcelapi.sourceforge.net/]
Once you get the content of the files, it's up to you how you display it in your swing application.
Demos and tutorials can be found on these sites as well.

Flash Player 10.3 and Windows 7 control panel

Hello,
I have installed flash player 10.3 in my system Windows 7 Prof. 32 with classic design but the text in the control panel is incomplete
http://www.picfront.de/d/8chS
I have read that with aero design the text is complete.

Yes, unfortunately there is an issue with the Native Control Panel under the Classic theme. If you use the standard Windows XP theme or the Aero-based themes, the Native Control Panel text should not be truncated.

Java Swing/AWT and FX is so old school! Give me HTML and CSS for GUI!

Dear Java,
I am a seasoned programmer and I feel it's time JAVA implements a GUI system where it uses HTML and CSS for the GUI. For the love of god just look at the interfaces you can make using HTML and CSS alone. I am a big fan of Java Swing and the recent GUI designer for FX is quite cool. But they are just not as simple as HTML and CSS. And JavaFX has some interesting requirements for the graphics.
I know it is possible to use JavaFX and implement the WebView/WebDriver and make it load a HTML page, etc... but why go through all the trouble?
Just imagine... if you make Java where it has powerful back-end to do what it does best and the HTML/CSS powered GUI on the front-end. It will make the lives of many developers much much easier.
I am not sure whether a Swing designed GUI will be faster than a HTML designed GUI... but if you look at a traditional browser and how fast it renders HTML/CSS, I am sure if Java had a native Form where it uses HTML and CSS to render the GUI, Java will make the dreams of many programmers a reality.
Make it happen!!!!

Chess: java swing help need

Hi, I have just learn java swing and now creating a chess game. I have sucessfully create a board and able to display chess pieces on the board. By using JLayeredPane, I am able to use drag and drop for the piece. However, there is a problem which is that I can drop the chess piece off the board and the piece would disappear. I have try to solve this problem by trying to find the location that the chess piece is on, store it somewhere and check if the chess piece have been drop off bound. However, I could not manage to solve it. Also, I am very confuse with all these layer thing.
Any suggestion would be very helpful. Thanks in advance
