Execution Of Swing Application On Another PC
Apr 6, 2014
I am writing a Java Swing GUI application on my pc. I have to give this application to my cousin with another pc, where he is not aware of programming. then how can he execute that application? are there any ways of skipping the "javac" and "java" procedures while executing the app on his computer?
I am using win7 x86 and same at my cousin's place. I am also using eclipse-kepler sr1 ide for app development.
Are there any easy ways of automating this "javac" and "java" process(compilation and execution)? something like...scripting?

I wish to use args passed to main(String[]) during application execution to a Swing component.
In a simple example, assume args passed are: a b c d
And here is the result I look for:
package argsinswing;
import javax.swing.JOptionPane;
public class ArgsInSwing {
public static void main(String[] args) {
String str1 = args[0];
[Code] ....

public class StringTest
{
public static void main(String args[])
{
String s1="hello";
s1=s1.concat("me");
String s2="hellome";
if(s1==s2) System.out.println("s1 and s2 has same referance");
if(s1.equals(s2)) System.out.println("s1 and s2 has same content");
}
}
Output is : s1 and s2 has same content
if after concatenation both string is stored in string pool it will refer to same memory location and other confusion is after any string operation like (concatenation , replace , substring) jvm creates a new string in which memory area..?? Heap or String pool.

I need to put a Web Page in my JFrame application , I got a lot codes on the internet and could implement without problems , but the problem is that this code has an ugly page as hell, with colored all wrong and with a very poor quality , one of code I used was this :
* import javax.swing . ;
{ public class SwingWebPage
public static void main ( String args [ ] ) throws Exception {
JEditorPane website = new JEditorPane ( " http://www.google.com/ " ) ;
website.setEditable ( false) ;
[code]...
If you test , you'll see that the page is displayed in the JFrame is horrible.

I lately started using "advanced" Swing-Components, like JTabbedPane and JComboBox, but I dont get the ComboBox working/This is the code I use:
public class PreferencesPanel extends JPanel
{
public PreferencesPanel (MapEditWindow window)
{
super ();
setLayout (new FlowLayout ());
String[] resolutions =
{
"1024x768", "1280x800"
[code]...
The TabbedPane is placed in another JPanel, which is placed in an Fullscreen-Window.
Now, the problem is, that when I start the application and open the "Preferences"-Tab, everything seems normal, I can see the ComboBox and the first entry is selected. But when I click it, instead of opening and offering me more choices, the program crashes and my screen turns black (I'm using OS X, on Windows it would possibly turn white, but I didnt test this out).

I'm developing a java swing application in which i need to show the map of some area and allow user to put markers on it. I've goggled a lot on the topic but unfortunately i haven't got any how i can do it.
I came across some ideas like displaying a web browser in swing just like JXBrowser (i can't afford JXBrowser). And I'm also not sure if this way will allow me adding markers.

I have a method "doSomething" which can take a while to be fully executed.
...
boolean bResult = false;
bResult = doSomething();
System.out.println("Result:" + bResult);
...
I would like to be able to stop the method execution after 10 seconds and continue the normal execution of my class. This means:
- If doSomething() is executed in 3 seconds for example, the System.out.println() statement shows the result of the method
- If doSomething() is executed in more than 10 seconds, after 10 seconds the method is stopped and the System.out.println() will always have false as result.

I have to create a Swing application for which i haved a set of requirements as,
1. there will be two JPanels ,left and right, on the main JFrame , left frame would contain a JTextField and a submit JButton ,user can enter values 1,2,3 ,in the JTextField and presses the JButton
a. if user enters 1, a JTextField will be shown on right JPanel
b. if user enters 2, a JTextField and a JRadioButton will be shown on right JPanel
c. if user enters 3, a JTextField and a JComboBox will be shown on right JPanel
So I have done that but when my boss sees the code behind this application he told me to make it more extensible i.e. if there is going to be an additional requirement for values 4 or 5 or 6 and so on , then i have to make minimal changes in my code or no change in my code and it should work . how this can be done ? is it possible make such software design ?
public class DesktopApp extends JFrame {
private static final long serialVersionUID = 1L;
private static final Logger logger = Logger.getLogger(DesktopApp.class);
private JPanel jp, jp2, mainPanel;
private JLabel jl, jl1, jl2, jl3, jl4, jl5;
private JTextField jText, jText2, jText3, jText4;
[Code] ....
What wrong am i doing here in this code which in not considered to be an extensible design ?

I am learning Java on my own and I am taking on very small project by myself for fun, and I'm just stuck on this small part of the project.
So I have created a text file that contains a small list of toy names and prices, like:
Barbie, 12.95
Lego, 15.99
Hot Wheels, 5.00
Power Rangers, 6.49
And what I would like is my application to read the contents of the file and store the toy names in a list component. And then I want to be able to select a toy name from the list and add it to a shopping cart that is a list component as well. I want to the application to have menu items and buttons to allow me to remove items from the shopping cart, clear the shopping cart of all selections, and check out. When I check out, the application should calculate and display the subtotal of all the toy names in the shopping cart, the sales tax (which can just be 8 percent of the subtotal), and the total.

I'm having trouble with this program. In my textbook it says "Write an application that displays a frame containing two panels. Each panel should contain two images (use four unique images - your choice). Fix the size of the first panel so that both of its images remain side by side. Allow the other panel to change size as needed. Experiment with the size of the window to see the images change orientation. Make sure you understand why the application behaves as it does". I successfully imported the images, but I can't find out anywhere how to allow the second panel to change size with the window.
import java.awt.*;
import javax.swing.*;
public class TwoPanels
{
public static void main(String[] args)
{
JFrame frame = new JFrame ("Embedded Images");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
ImageIcon iconOne = new ImageIcon ("glove.jpg");
ImageIcon iconTwo = new ImageIcon ("cleats.jpg");
ImageIcon iconThr = new ImageIcon ("bat.jpg");
ImageIcon iconFou = new ImageIcon ("baseball.jpg");
[code]...

I installed Windowsbuilder in Eclipse as described in this video:URL....
To get starated I now want to create a simple JFrame application that works in the following way. On the opening screen I want to present 4 buttons. Based on the selection I want the JFrame to change layout and components so that the same JFrame behind the scenes contains 5 layouts but only one visible at any time. What is the best way to accomplish this? Or should I do this in another way using multiple JFrames or similar?

My code runs and compiles just fine when I insert 3 values, however, if I add anymore values NOTHING happens. When I hit the compile button, my mouse pointer turns into that loading circle thing and after 3 seconds it disappears and nothing happens. No error or anything in the console, just BLANK. This problem occurs on line 12 in my main method, and my insert method is on line 41 in the third class..Here is my main method
public class TestAVLTree {
public static void main(String[] args) {
/*test at least 2 diff data types*/
//AVL of ints
AVLTree<Integer> avlInt = new AVLTree<Integer>();
avlInt.insert(100);
avlInt.insert(50);
avlInt.insert(200);
//avlInt.insert(3); fails here. could it be my insert method?
//avlInt.insert(17);
[code]....

I developed a swing application using group layout. It resizes when I resize the frame but when I change the screen resolution or when I run the application in a laptop which has small sized screen, the components over lap each other. I need my application to fit according to the screen resolution
The code is as follows
private void initComponents() {
jComboBox1 = new javax.swing.JComboBox();
jButton1 = new javax.swing.JButton();
jButton2 = new javax.swing.JButton();
jLabel1 = new javax.swing.JLabel();
jLabel2 = new javax.swing.JLabel();
jLabel3 = new javax.swing.JLabel();
[Code]...
According to the list item selected, an internal frame will appear in the desktop pane. I use group layout for that internal frame too.

I have my paint application, i use the following mouse event to draw my shapes (mousePressed, mouseReleased, mouseDragged). Now after the user paint a circle for example, he must be able to drag the shape; to be able to do this. i think i must again implement the different mouse Events. I have done it and the drag is not working. How can i achieve this. can we implement multiple (mousePressed, mouseReleased, mouseDragged) in the same java class??

I have a tree-based data structure that looks somewhat like this:image1.png..Every tree always has a height of no more then 3, and each of these classes has a very specific use, generalization is not possible between them.Now, I want to display my data structure with a JTree in a Swing application. A JTree needs a TreeModel and so I created a custom TreeModel for my classes, it looks like this:
public class CustomTreeModel implements TreeModel {
private Root root;
public Object getRoot() {
return root;
[code]....
But then I would introduce this interface to my Model classes just for the purpose of writing the View. So my data model has to be altered to make the View work, this sounds completely against MVC to me and also like something I dont really like.On the other hand, the CustomTreeModel would be much simpler, easier to understand, easier to maintain and just in general more pleasing to the eye.Should I change my Model to improve the View? Is instanceof okay to be used in View classes?

I try to create Java Swing Desktop application which show Road map of some area in JFrame. But pc not connected to internet it will be in LAN. Map should be like if we scroll the mouse we go down from height in map. Like zooming the area.
I try to find out by google i get lots of forum links but each showing me.
1. I have to do web application.
2. Google not support 'without internet' map facility.
3. I should use lots of jpgs which store in folder for showing map from various height so it look like when we see any map in Google Earth application.
I found goworldwind.org but not clear understanding right now.

I have a Single Frame Application and I simply want to prompt the user with a dialog confirming they really want to close before they actually close the program, specifically when they click the X in the upper right. I THOUGHT it was like any other java application, with the slight added complexity of having to target the program-created-JFrame with: ".getApplication().getMainFrame()".
MyApp.getApplication().getMainFrame().setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);
With that code, DO_NOTHING_ON_CLOSE is set on the JFrame, yet the program closes anyways. Which I don't understand.So I did some reading and found this: URL....That lead me to the configureWindow override, where I successfully tried this:
root.addWindowListener(new WindowAdapter() {
@Override
public void windowClosing(WindowEvent e) {
// write your code here
System.out.println("Window Closing");
}
});
But as far as I can tell that will only let me react to the window closing, not to the command to close it, where I could then kill the command in the dialog if they so "no I'm not ready to quit yet", if that makes sense. So, how to give a prompt before closing?I am using netbeans IDE to create this app - not sure if that is relevant, since maybe it is an oddity with the IDE and not Single Frame Applications.
