Emulator Using Java Swing
Apr 22, 2014
I desired to produce a GUI in Java swing which should be look like mobile phone, as rendered under. test.jpg...So now the user should press the buttons and he can see the operation on the given phone screen, like if user press button "1" then it should display on the screen.
public class SimulatorPanel extends JPanel
{
public static BufferedImage image;
public SimulatorPanel ()
{
super();
try

Basically, I wanted to develop a mobile simulator, but I having problem with GUI only. Or any open source simulator in Java?

I'm just starting to learn Java GUI. I'm trying to make a simple GUI that will update dynamically but having trouble ending the loop correctly.The Currently I've got the GUI updating and stopping, but the Test class method loop does not terminate correctly, it continues to count.

I am trying to get my MouseListener to change the foreground and background on hovering over and once the menu is clicked, unfortunately only mouseEntered & mouseExit works but once I click on the menu I loose the selected colours so I am trying to use mousePressed but it does not have any affect.
mnuFile.addMouseListener(new MouseAdapter() {
public void mouseEntered(MouseEvent evt) {
mnuFile.setForeground(Properties.ORANGE);
mnuFile.setBackground(Properties.BLACK);
}
public void mouseExited(MouseEvent evt) {
mnuFile.setForeground(Properties.WHITE);
mnuFile.setBackground(Properties.BLACK);

I am trying to save a state of a big GUI Swing app. I am trying to save the containers (ArrayLists and JPanels too ). But I am recieving an exceptions:
Java Code:
ilian.Quiz.MainApp$5
at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1183)
at java.io.ObjectOutputStream.defaultWriteFields(ObjectOutputStream.java:1547)
at java.io.ObjectOutputStream.writeSerialData(ObjectOutputStream.java:1508)
at java.io.ObjectOutputStream.writeOrdinaryObject(ObjectOutputStream.java:1431)
at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1177)
at java.io.ObjectOutputStream.writeArray(ObjectOutputStream.java:1377)
at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1173)
at java.io.ObjectOutputStream.access$300(ObjectOutputStream.java:162)
[code]...
What is causing it? I guess anonymous classes like new Thread(new Runnable(...) will cause errors.

I have a GUI with several buttons and I'm using NetBeans GUI Builder to do. At the click of one of these I would like for it to open another frame containing a picture. So I associate a listener (actionPerformed) the button and when clicked it opens actually post the new frame.
In the new frame I waxed a JLabel and then I associate the image of the label. I saw that to do that NetBeans generates this code:
label.setIcon(new javax.swing.ImageIcon(getClass().getResource("/img/tree.png")));
My problem is that the picture is overwritten several times during the execution of the program is not changed yet in the frame. That is, in the new frame is always displayed an old version of the image.
I have an image that is created every time I click on the button (it always has the same name and same path). Basically I have a generic tree on which I perform the operations (add, remove, etc..). When I click on the button I call a method that generates the image of the tree (using Graphviz). So I have one image that changes over the time...
How can I do so that the image is always up to date?
The Code:
package View;
import javax.swing.Icon;
import javax.swing.ImageIcon;
import javax.swing.JLabel;
public class AlberoIpotesi extends javax.swing.JFrame {

I would like a small box to be able to enter a contacts information and I started with building it thru netbeans. Now I am thinking I should start from scratch so I understand everything. What should I do? I am having trouble making the buttons at the bottom work. All I would like to be able to do is setFrameVisible(false); but I can't seem to be able to do that without loosing the whole project not just the frame I am working on.
The buttons I am referencing are the Cancel & Accept
public class pa4GUI extends javax.swing.JFrame
{
String ph;
String ln;
String fn;
String em;
String or;

I am a beginner with Java. I have never used SWING before but I have to use it now and I am clueless. I don't know if what I am doing is right.I need to create a simple calculator. My problem is getting the buttons the user clicks to appear in a text field. I know I haven't added the =/*- buttons yet.
I have left actionPerformed practically blank, what to put in ?

I'm trying to implement CSS in Java via a JEditorPane and an HTMLEditorKit. The CSS is included below. It *should* create a container with one on the left, small, and one on the right, large. It works flawlessly on JSFiddle [URL] ...., but on Java, it won't put the two divs next to each other. Is this a problem in Java/Netbeans or is it my problem? It creates the divs, but beneath each other. The JEditorPane is wide enough for all of them to fit.
Coding:
Java:
private void loadBulletins() {
//<editor-fold defaultstate="collapsed" desc="HTML/CSS Script">
String eBullStyles = "#divMsgs{ "
+ "height: 99px; "
+ "margin: auto; "
+ "background-color: #3399FF; "

So i'm using Netbeans and have created this template for the program i want to create. Basically what I want to do is enter a time and date in 24hr format including seconds and the date of start and end time and have the program calculate the time difference between Tool launch and tool Receive that takes into factor the Launch and Receive Dates for a total of hh:mm:ss duration. I don't know how to combine both those factors output one number in a total number of hours Duration. I'm also having problems linking the ODO (odometer) which the formula would basically be time/ODO (or distance in feet) = x.x ft/sec format.

I am in the progress of updating my code and re-testing after switching from Java 6 to Java 7. When I open multiple JInternalFrames in my application under java 6 I am used to closing the top most internal frame and having the frame immediately under it become the next active frame. When I run the same code under Java 7 I see a different behaviour in as much as when I close the last frame I opened, the next one to become active is the first one.
To illustrate this another way, lets say I open 5 internal frames, 1,2,3,4 & 5
In java 6 when I close frame 5, frame 4 becomes the active frame.
In java 7 when I close frame 5, frame 1 becomes the active frame.

Here is an example of a GUI. Is it possible to make this kind of a thing using Java Swing? Is it possible to have a picture on the entire background of the JFrame, and then other Swing components like buttons, labels etc. sitting on it?Is it possible to have action listeners behind pictures? In other words, they will behave like buttons: the user clicks on them and they do something.

With a simple "Hello World" application, once the println is executed the application exits and the process goes away.
If a simple Frame application is executed, the Frame is displayed, the println is executed but the application does not exit.
public class Frame3 extends JFrame
{
Frame3() {
setBounds(100,100,300,100);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setVisible(true);
}
public static void main(String args[]) {
new Frame3();
System.out.println("You are here");
}
}
It isn't that Java is aware an object exists because if I create a basic non-swing, non-gui object it will exit right after the println.
Q1. What is it that causes Java NOT to exit after creating the JFrame?
Q2. What type of object(s) when created will cause the application to continue running?
Q3. What would I do if I wanted the println statement to be executed only after the JFrame was closed?

I got a project at my university , and we are working with JBoss with the free version WildFly .And also with Java EE.
Now the application is a simple game of Battle Ships or sinking ships to be honest i am not sure as to how the game is actually called.
Registering a user and saving his or her information is not hard using a Stateless java bean , to save the data in the database.
I have a Stateful java bean for every user , the bean is created on the server side after the user succeeds in logging in to the game.
This bean is used mainly for sending an invite from one user to another , to log out the user and everything else that is needed for the user.
The main problem that i encountered here is that JBoss dose not let me have a reference on my frame inside of the bean.
This makes things hard because i would need to use a Timer to ask the bean every second or so if there is an invite from someone , and i would need to save all of the invites .
This was the only thing i could think of .And also implementing the game it self , the communication between users would be complicated more so than i think its needed.
Then my professor said that i could make a service on the clients side in witch i would have a reference of the JFrame , and i could send this service to the java bean and using this service i could get access to the JFrame making things faster.
This would make things a lot easier.For the invite and for the game itself too.
My professor explained that JBoss or WildFly is based on RMI , and he said also that i would need to set up the registry on the server side .But i got lost because i was not sure as to what should i search for .
We are using an older version of WildFly not the newest but one version older , CR1 i think.
And we are also using JPA in the Dynamic web project , server .
