How to print a JTable in Java Swing ?

Hi,
I have an application written in java swing.Now I want to write a print module that prints some details.The details includes the JTextArea and JTable that changes in size dynamically.One solution i found is to put them in a panel and print that panel.But it is static.The size of JTable and JTextArea changes, according to the given input.Please give me a solution for this.

Printing is a bit of a nightmare, actually. Most of the trouble is layout. Basically a Printable is passed a page number and a graphics context and has to work out what components go on that page and where. It can't depend on the pages being requested in sequence.
You can call getPrintable from a JTable, and you can call that through your own Printable in order to add extra pages. However you can't ask a Printable how many pages it's going to produce, you just have to invoke it and see if it returns a code to say that the page is out of range.
And the Printable JTable generates is very limited, the table has to occupy full pages, you can't tell it to start in a different place on the first page, or find out how much space it's used on the last page. The headers and footers generate JTable's own idea of a page number, not yours.
You can call print() on most Swing components, but you'll need to set their size and location first, and/or mess with the transformation in the graphics context.

How to play flash files in java swings

Hi All ,
I have a requirement in java swings , i want to play advertisements ( flash files in swings )
can any one provide any example for the above requirement .
Thank you all for sharing knowledge in this great forum .

I have a java desktop application which is actually a
kiosk application. I have to run some promotion
videos in my application when no user is using the
kiosk.Will the kiosks all be running the same OS?
The reason I ask is that JMF is available in both
standard and performance pack versions. The PP
provides a wider variety of formats, but runs only
on Win. and *nix.
videos can be any avi or neother which can easily be
played in java applications.That is handy. The JMF standard pack provides
support for a number of flavors of AVI, but not all.
What is the best way for me to play video files in a
java application??I would suggest checking if the 'standard' version
of the JMF can play* the current AVI's. If it can, use
the standard JMF for the project, if not, look to
converting the AVI's to something the JMF can
deal with, this might involve storing the video or
audio of the AVI's in a different format - you
might have to experiment to get the right
combination, but the JMF 'supported formats'
is a good guide.
http://java.sun.com/products/java-media/jmf/2.1.1/formats.html
* To check if JMF can play them, install it and
try loading the AVI's in JMStudio - the default
player.

How to invoke a JAR from Java Swing application?

Hi,
I am trying to start a jar file from the swings application.
I am trying the following code,
String cmd[] = new String[]{"cmd", "java -jar TestJFreeChart.jar"};
try
Process run = Runtime.getRuntime().exec(cmd);
catch(Exception e)
{}Is anything wrong in the usage?

First try:
"cmd /c java -jar app.jar" or cmd start, because it can't jsut run java.exe, it needs to be
passed to the cmd interpretor witch further calls java.exe, etc
Also read what stevejluke suggested. Its important to know if .waitFor or not.
You wont understand these until you read the tutorial.

Take the input and see if it's "state", "city" or "area". Then read another input for its name. Then go through all the items you have and check whether there's a match.

How to display XML file in java swing

now i do my M.Sc., project on data maining.this time i have one problem,thats i can't display XML file in swing frame.so any one know this plz give me that idea or code.
Thanks to all.
RSK

One way of doing that is to use JDOM...
u create an xml tree, and then output using XMLOutputter class...it will be displayed in text...im not sure if thats what u want...however, if u do want to represent it visually then u may need to draw a tree...u may use the Graphics2D for that...there are alot of ways to do such thing, and the 2 possibilities arent the best...depends on what u want...elaborate more pls.

Sure: see below!
WARNING: this code will not compile as is because it uses some other classes from my personal code library (FileUtil & StringUtil). The particular methods of those classes which are used below are trivial methods that anyone can write, which is is why I have not posted them as well. So, to get the code below to compile, you can
a) write your own versions of these classes or
b) simply add the necessary methods to this class or
c) simply comment out their usage (in the case of StringUtil, which is just used for arg checking)
But if you still want me to post them, then I can post the relevant fragments of those classes.

* Class which supports taking screen shots of the entire desktop, AWT Components, or Swing JComponents.
* This functionality is implemented in a series of <code>take</code> methods, each of which returns a BufferedImage.
* This class also offers convenience <code>write</code> methods for storing BufferedImages to files.
* 
* The images taken by this class should be the precise images seen on the screen.
* However, the images written to files may deviate from the originals.
* One obvious cause is limitations of the chosen file format (especially with lossy formats like jpeg).
* A subtle issue can occur, however, even when using lossless formats like png:
* if the file is subsequently opened by another application,
* that application may rescale the image, which can often cause visible artifacts.
* <blockquote>
* To see this last problem on Windows XP,
* call {@link #take()} which returns an image of the entire desktop and write it to a file,
* and then open the file with XP's default graphics file viewer ("Windows Picture And Fax Viewer").
* This program shrinks the desktop image in order to fit it inside the program's window,
* and rescaling artifacts are readily seen, especially if the desktop image has any kind of text in it.
* If "Windows Picture And Fax Viewer" instead cropped the image or had a scroll pane, then this should not happen.
* </blockquote>
* 
* Acknowledgement: this class was inspired by the program
* <a href="http://www.discoverteenergy.com/files/ScreenImage.java">ScreenImage</a>.
* Differences from the above program:
* <ol>
* <li>this class uses {@link BufferedImage#TYPE_INT_ARGB} instead of {@link BufferedImage#TYPE_INT_RGB} in order to preserve alpha</li>
* <li>this class's {@link #formatNameDefault default image file format} is PNG instead of JPEG</li>
* <li>this class's <code>take</code> methods simply take snapshots and never have the side effect of writing image files</li>
* <li>this class added a version of <code>take</code> which can get a snapshot of a region of a Component</li>
* <li>
* when taking a snapshot of a region of a Component or JComponent,
* the Rectangle that specifies the region always has coordinates relative to the origin of the item
* </li>
* </ol>
* See also:
* <a href="http://forum.java.sun.com/thread.jspa?forumID=57&threadID=597936">forum discussion #1 on screen shots</a>

* 
* It might appear that this class is multithread safe
* because it is immutable (both its immediate state, as well as the deep state of its fields).
* However, typical Java gui code is not multithread safe, in particular, once a component has been realized
* it should only be accessed by the event dispatch thread
* (see <a href="http://java.sun.com/developer/JDCTechTips/2003/tt1208.html#1">Multithreading In Swing</a>
* and <a href="http://java.sun.com/developer/JDCTechTips/2004/tt0611.html#1">More Multithreading In Swing</a>).
* So, in order to enforce that requirement, all methods of this class which deal with components
* require the calling thread to be the event dispatch thread.
* See the javadocs of each method for its thread requirements.

public class ScreenShot {

 * The current value is {@link BufferedImage#TYPE_INT_ARGB}, which was chosen because
 * <ol>

 * <li>the "_INT" types are the fastest types (the "BYTE" types are slower)

How to create the digital clock in java swing application ?

I want to create the running digital clock in my java swing application. Can someone throw some light on this how to do this ? Or If someone has done it then can someone pl. paste the code ?
Thanks.

hi prah_Rich,
I have created a digital clock you can use. You will most likely have to change some things to use it in another app although that shouldn't be too hard. A least it can give you some ideas on how to create one of your own. There are three classes.One that creates the numbers. a gui class and frame class.
cheers:)
