I have dragged and dropped a jTextArea from netbeans palette onto my form. But when I right clicked for Event > action > actionPerformed for implementation, I realized such was not there, unlike the jTextField component. For example, I have tried this but it didn't work:
//{
Import java.swing.*;
JTextArea txa = new JTextArea();
txa.getText(jTextArea1);
txa.setText(jTextArea1);
txa.setTextWrap(true);
//}
i have this code when i selected a node it display the attribut and value of it in JTextArea but i want it into table :
public void valueChanged( TreeSelectionEvent event )
{
if( event.getSource() == jtree ){
{
FramePrincipale.getExplorePanelll().setText(null);
TreePath path = jtree.getSelectionPath();
String a = changeString(path);
Hashtable env1 = System.getProperties();
env1.put(Context.INITIAL_CONTEXT_FACTORY,
"com.sun.jndi.ldap.LdapCtxFactory");
env1.put(Context.PROVIDER_URL, "ldap://localhost:11389/");

I need to make a simple applet, but I'm stuck with something. This is how my applet should look:
And this is how that part looks in my applet:
What I've done until now is create one JPanel which includes two other JPanels.. The first one contains only the JTextArea you can see, and the other one includes the other elements.
I just need to make the JTextArea taller, like in the example, so everything comes into place...
I am adding a JTextArea to my JPanel with this code:
commentTextArea.setLineWrap(true);
commentTextArea.setWrapStyleWord(true);
commentTextArea.setVisible(true);
this.add(commentTextArea);
commentTextArea.setBounds(0, 0, 100, 100);
//commentTextArea.setLocation(0, 0);
Whenever I use setLocation(0,0), the JTextArea never moves. It is always in the top middle of the screen, not at (0,0). The same goes for setBounds(0,0,100,100) BUT the height and width are set this way, just not the location. Why is this?

I have a problem with my code,in fact I can't output the stream from console to my jTextarea,this is my code:
public class AudioFrame extends javax.swing.JFrame {
static double[] audioFile;
static String audioToDecode;
static String audioKey;
static String outputName;
static String outAudio;
static String name;
static int command;
static String textToEncode;

I am currently working on a project that can save text from a JTextArea and also open that same saved text. The problem I am having is that when I open the saved text file it is no longer formatted.
How the file looks before saving/closing:
public class HelloWorld{
System.out.println("Hello World!");
}
How the file looks after being saved/closed then opened:
public class HelloWorld{ System.out.println("Hello World!");}
When I save the file I'm actually saving the entire thing to a single string. When I do this the String eliminates all tabbed spacing and pushes all characters to one single line.
The only ideas I had for fixing this were to either somehow use Format in the String class or record every time user tabs and add to the String.
I have a program with a main panel JPanel that implements KeyListener. I added a JTextArea to which I added as the KeyListener: this, meaning the main panel. I made the JTextArea fill the entire main panel because I want to catch a key press anywhere in the main panel.I catch the key presses and the program does what I want it to.
I added a JToolBar to the program; it is working just fine.Now that I have two components on the main panel - toolbar and panel with textarea -, the textarea must have the focus before it will send the KeyEvent and call keyPressed(). I don't want to expect the user to click on the main window to get the program to start or after each time they use the toolbar.
I have tried calling both requestFocus() and requestFocusInWindow() on the textarea; neither call worked. I put the toolbar at PAGE_END instead of PAGE_START; this worked to allow the program to start but I don't want to have the toolbar at the bottom and once I clicked on a toolbar button, the textarea lost the focus.
I need to be able to give the textarea the focus when the program starts and after the user uses a toolbar button. (I suspect that if I solve the problem when the program starts, I can use the same method after handling a button press.)
Here's a snippet of code from a program I'm making:
private void init() {
...
testInfo = new JTextArea("Progress log:
");
testInfo.setEditable(false);
testInfo.setLineWrap(true);
testInfo.setPreferredSize(new Dimension(testInfo.getPreferredSize().width, 200));
scrollPane = new JScrollPane(testInfo);
scrollPane.setHorizontalScrollBarPolicy(ScrollPaneConstants.HORIZONTAL_SCROLLBAR_NEVER);
scrollPane.setVerticalScrollBarPolicy(ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS);
...
add(scrollPane);
}
The problem is, the JTextArea that's created has a "limited" number of rows - it seems you can still enter more lines than the "limit", but they don't show. I thought it was a problem with the JScrollPane but I'm not so sure...
So, I have a program that allows me to dynamically add JTextAreas and then drag them around the screen. The problem is, when I add a new JTextArea, I call revlidate() to update the panel. This causes all of the JTextAreas to reset their positions. How can I prevent this from happening? It is happening on this code:
public void addBox() {
drag = new DragListener();
JTextArea textArea2 = new JTextArea("Some text
Some other text");
textArea2.setLineWrap(true);
textArea2.setWrapStyleWord(true);

I have small problem in GUI. I have a text area which has to display my test orders now what is happening instead of the text showing up in the JtextArea its still printing to the console so this order code (yes i did not use proper code standers) runs though my order class fine but its not loading the text in the JtextArea
Order code
public static String testCase1(){
orders ords = new orders();
System.out.println("Test Case 1: " + "
" + ords.getOrderDetails());
return " ";
My jbutton code :
txtContent.setText(new orderTester().testCase1());
txtContent.setText(new orderTester().testCase2());
txtContent.setText(new orderTester().testCase3());
I have 10 test case to load in the jTextArea
I have a swing application that gets football scores from a website using Jsoup.
When the "Get Scores" button is pressed, the scores are printed to a JTextArea with a JScrollPane.
I have also used a SwingWorker to update the scores every couple of seconds.
My problem is that every time the JTextArea updates, the JScrollPane scrolls back to the top of the text area. I wan the scroll bar to stay where the user left it.
Here is my code (The update is currently set to update every 1 second so you can see what the scroll bar is like).

ActionPerformed and ActionListener on Netbeans...If I create a ComboBox on Netbeans using GUI design, then I right click over the Combobox I can find Events - Action - ActionPerformed... but I can't find ActionListener...
Are ActionPerformed and ActionListener the same?
or...
where is ActionListener on GUI Netbeans? Do I need to manualy write the ActionListener part?
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

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; "

How do I move focus from a jcombobox to a specific component say a jtextarea.
My attempt below seems to be moving to a random component not the desired jtextarea.
takenByCombo.addKeyListener(new KeyAdapter() {
public void keyPressed(KeyEvent e) {
if (e.getKeyCode() == KeyEvent.VK_TAB ) {
e.consume();
dayJTArea.requestFocus(); // focust not moving dayJTArea
}
}
});
I applied the above logic to move focus from a specific jtextarea to another jtextarea as seen below and it works as desired.
dayJTArea.addKeyListener(new KeyAdapter() {
public void keyPressed(KeyEvent e) {
if (e.getKeyCode() == KeyEvent.VK_TAB ) {
e.consume();
monthJTArea.requestFocus();
}
}
});
I'm trying to use netbeans GUI creator to create a chessprogram. However, the default "freeflow" layout is very difficult to work with. However, when I switch the layout to gridbag or border layout, I can't figure out really how to do anything. I don't know how to resize or position elements. Any good set of tutorials for using netbeans GUI creator with non standard layouts?
(I originally used absolute layout, which I can easily add and position elements in, but which I abandoned because i want the chessboard squares to resize when the window changes size).
I am still learning how to perfectly use the netbeans palette. I just created a GUI and want to use jTable on it. I have also dragged and dropped jTable component on my GUI. What should I do thereafter? My aim is to allow user input figures into cells, sum up the figures and enter same into a database. I have not used jTable before in java.

View Replies View RelatedI am writing a ComputerBaseTest application with Netbeans. I have each question on a panel and I want the questions(panels) to be switched, viewing the previous and the next question on a single frame, but I do not know how.
I only understand frame switching if each questn is to be on a frame but each score on each question (frame) do not sum up to give the overall score at the end of the test. Using multi-frame shows a sign of bad programming.
I am trying to make a ChessBoard class composed of an array of JLabels inside a JPanel with a grid layout. I am also trying to override the getPreferredSize method so that the board will change size when I resize the main window (in another class in which I will instancize this class as part of a larger GUI). I got this kind of layout working before, but now I am trying to get it to work with multiple classes. However, after copying in the part of the previous code corresponding to the panel's layout, I am encountering some errors that I don't know how to solve. Specifically, when I try to override the getPreferredSize method, the compiler tells me "method does not override or implement a method from a super type, " and that it can't find the method "getPreferredSize"
Here's my code:
public class ChessBoard extends JPanel//the panel that this class extends is the boardHousing
{
//mental chess board piece array
Piece mentalBoard[][] = new Piece[8][8];
//actual GUI chessboard JLabel Array
static JLabel chessBoard[][] = new JLabel[8][8];
[Code] ....
I would just think that I was overriding the method incorrectly, but the weird thing is that I got that specific section of code to work before -- the only thing different now is that there are multiple classes, so my ChessBoard class itself is extending JPanel.
I've used Netbeans IDE to create a simple Swing JFrame container, class NewJFrame.
NewJFrame calls another JFrame with dialog in it. Problem is there is an endless call made to it. Here's the issue relevant piece of code:

public class NewJFrame extends javax.swing.JFrame implements ActionListener {
.........
public NewJFrame() {
initComponents(); //IDE auto generated code for binding
