Java Swing Help

Hi, I am currently using a program called JPadPro for my java source codes. I am just beginning to learn java and I have just started on Java Swing GUI codings. My problem is that the program compiles, but it doesn't run. It always give me an error saying
"Cannot find main method, Program will exit". there is nothing wrong with my source code because I can run somewhere else. I think I didn't configure my Jpadpro correctly. (but anything without GUI does work)
Thank You for your help :)

Even though you are running a swing application, you still need a main method just as in non-GUI applications. The main should create an instance of the JFrame at the base of you swing app. A simple example is as follows:
public class mySwingApp extends JFrame {
public mySwingApp(String title) {
super(title);
// GUI components, layouts, possible listeners here
public static void main(String[] args) {
JFrame mainFrame = new mySwingApp("My first swing app");
mainFrame.setSize(200, 200);
mainFrame.setVisible(true);
}Hope this helps some!

Problem with java swing button and loop

Problem with java swing button and loop
I�m using VAJ 4.0. and I�m doing normal GUI application. I have next problem.
I have in the same class two jswing buttons named start (ivjGStart) and stop (ivjGStop) and private static int field named Status where initial value is 0. This buttons should work something like this:
When I click on start button it must do next:
Start button must set disenabled and Stop button must set enabled and selected. Field status is set to 1, because this is a condition in next procedure in some loop. And then procedure named IzvajajNeprekinjeno() is invoked.
And when I click on stop button it must do next:
Start button must set enabled and selected and Stop button must set disenabled.
Field status is set to 0.
This works everything fine without loop �do .. while� inside the procedure IzvajajNeprekinjeno(). But when used this loop the start button all the time stay (like) pressed. And this means that a can�t stop my loop.
There is java code, so you can get better picture:
/** start button */
public void gStart_ActionEvents() {
try {
ivjGStart.setEnabled(false);
ivjGStop.setEnabled(true);
ivjGStop.setSelected(true);
getJTextPane1().setText("Program is running ...");
Status = 1;
} catch (Exception e) {}
/** stop button */
public void gStop_ActionEvents() {
try {
ivjGStart.setEnabled(true);
ivjGStart.setSelected(true);
ivjGStop.setEnabled(false);
getJTextPane1().setText("Program is NOT running ...");
Status = 0;
} catch (Exception e) {
/** procedure IzvajajNeprekinjeno() */
public void IzvajajNeprekinjeno() { //RunLoop
try {
int zamik = 2000; //delay
do {
Thread.sleep(zamik);
PreberiDat(); //procedure
} while (Status == 1);
} catch (Exception e) {
So, I'm asking what I have to do, that start button will not all the time stay pressed? Or some other aspect of solving this problem.
Any help will be appreciated.
Best regards,
Tomi

This is a multi thread problem. When you start the gui, it is running in one thread. Lets call that GUI_Thread so we know what we are talking about.
Since java is task-based this will happen if you do like this:
1. Button "Start" is pressed. Thread running: GUI_Thread
2. Event gStart_ActionEvents() called. Thread running: GUI_Thread
3. Method IzvajajNeprekinjeno() called. Thread running: GUI_Thread
4. Sleep in method IzvajajNeprekinjeno() on thread GUI_Thread
5. Call PreberiDat(). Thread running: GUI_Thread
6. Check status. If == 1, go tho 4. Thread running: GUI_Thread.
Since the method IzvajajNeprekinjeno() (what does that mean?) and the GUI is running in the same thread and the event that the Start button has thrown isn't done yet, the program will go on in the IzvajajNeprekinjeno() method forever and never let you press the Stop-button.
What you have to do is do put either the GUI in a thread of its own or start a new thread that will do the task of the IzvajajNeprekinjeno() method.

JAVA(Ajax + (SVG or XAML)) is better than JAVA(Swing or SWT)?

A new startup claims it has invented a process to create reusable Ajax GUI Classes that are better than Java/Swing classes.
http://cbsdf.com/misc_docs/why-gui-api.htm
http://cbsdf.com/misc_docs/gui-api-brief.htm
It has published the innovative process and many examples on the web site and challenging the software community to prove it wrong.
Any takers?
It claims the process is very simple any Java developer with some JavaScript experience can validate the process.
Imagine the implications if they are right, and if it costs less to create a graphics intensive online application than the cost of creating a comparable Java/Swing application?

Chess: Java Swing problem!! 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

I wonder if you are biting off a little more than you can chew. This seems like a big project for a beginning coder. Anyway, my suggestions can only be general since we only have general information:
1) Break the big problem down into little pieces. Get the pieces working, then put them together.
2) Make sure your program logic is separate from your GUI.
3) If still having problems, post an SSCCE. See this link to tell you how:
http://homepage1.nifty.com/algafield/sscce.html
4) And as camikr would say (and flounder just said): next time, post this in the Swing forum.
Good luck!

Problem in printing a java swing form

Hi,
Could anyone help me on how to set the page margings while I print a java swing form since it is taking a lot of space as margins in the top right top and bottom how do i do that. or is it that java can only print in the printable area or is there any way i can increase the scope of the printable area

I used PrintRequestAttributeSet and set the margins to 0.5 on all four sides by creating an instance of MediaPrintableArea. By default, the margins on all sides comes up as 1.0 inch. Default paper size is LETTER (8.5 x 11).
PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet();
aset.add(new MediaPrintableArea(0.5f,0.5f,7.5f,10.0f,MediaPrintableArea.INCH);
PrinterJob printJob = PrinterJob.getPrinterJob();
printJob.setPrintable(component);
if(printJob.printDialog(aset))
printJob.print(aset);
hope it helps.

Java Swings Vs Flex which is better?

Hi,
I do not know whether this is the right place to post this thread. We are planning to replace Java Swings client with Adobe Flex GUI. So I am in the process of analyzing the performances and advantages of Flex over Java Swings.
So, Can any one kindly let me know whether Flex supports all the features of Java Swings (like components... etc).
Actually my backend server is also Java and the communication between client and server is based on CORBA.
So, considering all these constraints please comment on this.
Regards,
Purush.

Both support object-oriented GUI development. The same core ideas apply to both, so the jump for a developer isn't too intense. Perhaps the largest difference is that Flex has XML layout files which is a nice plus (although many abuse the capability of injecting logic into it as well). JavaFX is the Java-world answer to Flex, so you may want to play around with that first since it will be more familiar.

Facing problem in Java Swing

Hi Sir,
I am using a java GUI Object for taking user name and password (in fields of user name and password) and would like to send the information to a server (in the form of Xml file) on the click of 'Ok' button. The database of registered user is stored on server. If the entered users name or passwords are not correct, the server will send a failure notification to the client (terminal where we typed user name and password). If this is successful, it gives a success notification.
I am doing this using Swings. Also I want all the communication taking place between the server and the client in the form of XML files. being a new to Swings I am facing certain difficulty.
I will appreciate your suggestions and help in this regard.
Thanks and regards,
Sarib

1. Determine what it is that you want the database to do and what you want your code to do. This does NOT involve writing code.
2. Learn JDBC
3. Write JDBC classes that does ONLY the database functionality from 1. If it has GUI (swing) code then it is wrong.
4. Unit test it.

Draggable buttons in Java Swing

Hi,
I want to develop an application in Java Swing. The application I am going to develop is an application for developing other applications. I want my application to include a button which also acts as a drag and drop UI element. For example, I want my application to include a button for adding a picture. There are 4 buttons of different pictures. If a user wants to add a picture he can either click on one of these buttons and that picture will be added somewhere on the screen or dragging this button and drop it and that picture will be added where he dropped that button.
Could anyone please tell me
1. If I can develop an application which includes Drag and Drop UI element if I develop it in Java Swing
2. If a button (or other UI element) can act as both a button and a drag and drop element if I develop my application in Java Swing
3.
Could you please tell me where I can find some screenshots of applications which has been developed in Java Swing? I am not familiar with this program and I am not that good at programming, so I would like to get some impression of how it might look like.
Thanks in advanced

1. the good thing about Swing is that it is very flexible and with clever programming you can do just about anything. The problem is that depending on your requirements, this could require a great deal of programming that can be very hard to implement such that it works properly on all popular platforms (windows, linux, mac).
2. see 1.
3. Swing applications are "skinnable", you can give them a great number of different appearances. The default is to give the application a system look and feel, so they look pretty much like any other application for that platform. This means that when you run your application on Windows, it will look like a Windows application, if you run it on a Mac it will look like a Mac application, etc.
I am not familiar with this program and I am not that good at programmingThat is quite a problem, because Swing is not the easiest API around. It requires a solid knowledge of Java and Object Oriented Programming in general as the entire API is based heavily on OOP concepts. To get a better idea of Swing, read through the Swing tutorial here:

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.

What is difference between C# Gzip and Java swing GZIPOutputStream?

Hi All,
I have a Java swing tool where i can compress file inputs and we have C# tool.
I am using GZIPOutputStream to compress the stream .
I found the difference between C# and Java Gzip compression while a compressing a file (temp.gif ) -
After Compression of temp.gif file in C# - compressed file size increased
while in java i found a 2% percentage of compression of data.
Could you please tell me , can i achieve same output in Java as compared to C# using GZIPOutputStream ?
Thank a lot in advance.

797957 wrote:
Does java provides a better compression than C#?no idea, i don't do c# programming. and, your question is most likely really: "does java default to a higher compression level than c#".
Btw what is faster compression vs. better compression?meaning, does the code spend more time/effort trying to compress the data (slower but better compression) or less time/effort trying to compress the data (faster but worse compression). most compression algorithms allow you to control this tradeoff depending on whether you care more about cpu time or disk/memory space.

PL/SQL and Java Swing interface

Everybody in this forum knows that Oracle is the best database around
with many functionalities, stability, performance, etc. We also know
that PL/SQL is a great language to manipulate information directly
in the database with many built in functions, OOP capability,
transaction control, among other features. Today an application that
manipulates information, which needs user interface, requires components
to be developed using different technologies and normally running in
different servers or machines. For example, the interface is done using
a dynamic HTML generator like JSP, PHP, PL/SQL Web Toolkit, etc.
This page is executed in an application server like Oracle iAS or
Tomcat, just to name two, which in turn access a database like Oracle to
build the HTML. Also rich clients like Java applets require an intermediate
server to access the database (through servlets for example) although
it is possible to access the database directly but with security issues.
Another problem with this is that complexity increases a lot, many
technologies, skills and places to maintain code which leads to a greater
failure probability. Also, an application is constantly evolving, new
calculations are added, new tables, changed columns. If you have an
application with product code for example and you need to increase its
size, you need to change it in the database, search for all occurrences
of it in the middle-tier code and perhaps adjust interfaces. Normally
there is no direct dependency among the tier components. On another
issue, many application interfaces today are based on HTML which doesn't
have interactive capabilities like rich-client interfaces. Although it
is possible to simulate many GUI widgets with JavaScript and DHTML, it is
far from the interactive level we can accomplish in rich clients like
Java Swing, Flash MX, Win32, etc. HTML is also a "tag-based" language
originally created to publish documents so even small pages require
many bytes to be transmitted, far beyond of what we see on the screen.
Even in fast networks you have a delay time to wait the page to be
loaded. Another issue, the database is in general the central location
for all kinds of data. Most applications relies on it for security,
transaction and availability. My proposal is to use Oracle as the
central location for interface, processing and data. With this approach
we can create not only the data manipulation procedures in the database,
but procedures that also control and manage user interfaces. Having
a Oracle database as the central location for all components has many
advantages:
- Unique point of maintenance, backup and restore
- Integrated database security
- One language for everything, PL/SQL or Java (even both if desired)
- Inherited database cache, transaction and processing optimizations
- Direct access to the database dictionary
- Application runs on Oracle which has support for many platforms.
- Transparent use of parallel processing, clusters and future
background technologies
Regarding the interface, I already created a Java applet renderer
which receives instructions from the database on how to create GUI
objects and how to respond to events. The applet is only 8kb and can
render any Swing or AWT object/event. The communication is done
through HTTP or HTTPS using Oracles's MOD_PLSQL included in the Apache
HTTP server which comes with the database or application server (iAS).
I am also creating a database framework and APIs in PL/SQL to
create and manipulate the client interface. The applet startup is
very fast because it is very small, you don't need to download large
classes with the client interface. Execution is done "on-demand"
according to instructions received from the database. The instructions
are very optimized in terms of network bandwidth and based on preliminary
tests it can be up to 1/10 of a similar HTML screen. Less network usage
means faster response and means that even low speed connections will
have a good performance (a future development can be to use this in
wireless devices like PDAs e even cell phones, just an idea for now).
The applet can also be executed standalone by using Java Web Start.
With this approach no business code, except the interface, is executed
on the client. This means that alterations in the application are
dynamically reflected in the client, no need to "re-download" the
application. Events are transmitted when required only so network
usage is minimized. It is also possible to establish triggering
events to further reduce network usage. Since the protocol used is
HTTP (which is stateless), the database framework I am creating will
be responsible to maintain the state of connections, variables, locks
and session information, so the developer don't need to worry about it.
The framework will have many layers, from communication up to
application so there will be pre-built functions to handle queries,
pagination, lock, mail, log, etc. The final objective is to have a
rich client application integrated into the database with minimum
programming and maintenance requirements, not forgetting customization
capabilities. Below is a very small example of what can de done. A
desktop with two windows, each window with two fields, a button with an
image to switch the values, and events to convert the typed text when
leaving the field or double-clicking it. The "leave" event also has an
optimization to only be triggered when the text changes. I am still
developing the framework and adjusting the renderer but I think that all
technical barriers were transposed by now. The framework is still in
the early stages, my guess is that only 5% is done so far. As a future
development even an IDE can be created so we have a graphical environment
do develop applications. I am willing to share this with the PL/SQL
community and listen to ideas and comments.

Is it sound like Oracle Portal?
But you want to save a layer 9iAS.
Basically, that was the WebDB.(Oracle changed the name to Portal when version 3.0)
Over all, I agree with you.

I would like to build 'ZOPE' inside Oracle DB as a back-end
Using Flash MX as front-end.
