I made this program for discord. This program takes your text and puts it in this 'format' that allows discord to convert it to fancy letters. My problem is that while typing the text lags behind by 1 character. I am only a beginner and I don't know what to do to fix it.
Ps. I do not feel like using a button to convert the text!
My Code :
textField = new JTextField();
textField.addKeyListener(new KeyAdapter() {
#Override
public void keyTyped(KeyEvent e) {
textArea.setText("");
separatedText = textField.getText().toLowerCase().toCharArray();
for(int i = 0; i < separatedText.length; i++) {
textArea.append(separate ? ":regional_indicator_" + separatedText[i] + ":\n" : ":regional_indicator_" + separatedText[i] + ":");
}
}
});
You can achieve this by adding a Document Listener to your JTextField. You don't give us what the "separate" boolean is, so i made the example in case this boolean is always true.

I am new in java swing unfortunately when i want to set action listener to one of the button that it has to get the textArea content and send that to another class it doesn't work in a way that i expect and instead it works when i change the text area's content, i don't know What's happened?
first button i named Button and the same problem happened when i use another action listener inside the Button's action listener named Clac
here is my code:
import java.awt.BorderLayout;
import java.awt.FlowLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JOptionPane;
public class FFT_Main_Frame extends JFrame {
JLabel label;
JButton button;
TextPanel txtPanel;
JButton Button;
JLabel label1;
// JTextArea[] BoxArray;
makePolynomial mp;
JButton Calc;
Complex[] Nums;
Complex[] Result;
int input;
FFT_Main fft_main;
ShowResult shr;
public FFT_Main_Frame() {
Button.addActionListener(new ActionListener() {
// Test t;
// Integer content;
#Override
public void actionPerformed(ActionEvent arg0) {
try {
Integer content = new Integer(Integer.parseInt(txtPanel.getTextArea()));
input = content;
System.out.println(input);
// inputt=input;
mp = new makePolynomial(content);
setLayout(new FlowLayout());
add(mp);
// setLayout(new BorderLayout());
add(Calc);
Nums = new Complex[input + 1];
Calc.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent arg0) {
for (int i = input; i >= 0; i--) {
Nums[i] = new Complex(Double.parseDouble(mp.BoxArray[2 * (i + 1) - 1].getText()),
Double.parseDouble(mp.BoxArray[2 * i].getText()));
}
for (int i = 0; i <= input; i++) {
System.out.println(Nums[i]);
}
fft_main = new FFT_Main();
Result = new Complex[input];
Result = fft_main.Recursive_FFT(Nums);
shr = new ShowResult(Result);
setLayout(new BorderLayout());
add(shr, BorderLayout.CENTER);
System.out.println("Result\n\n");
for (int i = 0; i <= input; i++) {
System.out.println(Result[i]);
}
}
});
} catch (NumberFormatException exception) {
JOptionPane.showMessageDialog(null, "Please Enter Just Numbers! ", "Wrong Value",
JOptionPane.ERROR_MESSAGE);
}
}
});
}
}
thanks for your help
You are using action listener wrong way here is an example how to use it
public FFT_Main_Frame() {
JButton Button = new JButton("Button");
Button.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent arg0) {
try {
// Code Here
}catch(Exception e) {
// Code Here
}
});
JButton Calc = new JButton("Calc");
Calc.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent arg0) {
// Code Here
}
});
}
}

My goal is to create a filtered combobox.
I create an editable combobox. When the user enters text, the code searches matching items in the model. When the user leaves the combobox, the code selects the selected item from the list. Further, the text from the editor component gets the value of the selected item.
When the focus goes back to the combobox via shift + tab, the editor component gets the text of the selected element. After releasing the shift key, the keylistener runs. In this case, the editor component contains the text entered previously, e.g., the value set when the focus is lost.
How can I set the text of the editorComponent to make it persist?

I am trying to get this SwingWorker to function correctly. However,the variables that need to be accessed seem to be not global. What do I do? I tried adding static but it creates more errors and complications later about accessing static from non static. The variables that are not working in the SwingWorker are the LOCAL_FILE and URL_LOCATION variables.

Your program is mostly a huge static main method. You're kind of getting the cart in front of the horse trying to do advanced programming such as with SwingWorker before first creating clean OOP code. In other words -- start over and do it right. Then the connections between classes will be much more natural and it will be much easier to get things to work right. The main method should only concern itself with starting the Swing event thread, creating a GUI object in that thread, and displaying it. Everything else should be in classes that create objects.
Also, on a more practical level, you have yet to tell us what variables are causing you trouble or what errors you might be seeing. Also, where are you trying to create and execute the SwingWorker?
Edit
One tip that will likely help: Give your SwingWorker class a constructor, and pass important parameters into your SwingWorker object via constructor parameters. Then use those parameters to initialize class fields that will be used in the SwingWorker's doInBackground method.
e.g.,
class DownloadWorker extends SwingWorker<Integer, Integer>
{
private String urlLocation;
private String localFile;
public DownLoadWorker(String urlLocation, String localFile) {
this.urlLocation = urlLocation;
this.localFile = localFile;
}
protected Integer doInBackground() throws Exception
{
try {
URL website = new URL(urlLocation);
ReadableByteChannel rbc = Channels.newChannel(website.openStream());
FileOutputStream fos = new FileOutputStream(localFile +"\\ProfessorPhys.iso\\");
fos.getChannel().transferFrom(rbc, 0, Long.MAX_VALUE);
System.out.println("--------\nDone Downloading\n---------");
} catch (Exception e) {
System.err.println(e);
}
return 42;
}
protected void done()
{
try
{
System.out.println("done");
}
catch (Exception e)
{
e.printStackTrace();
}
}
}

A few tricks to help others read and understand your code:
Use coherent and appropriate indentation (I personnally try to stick to default Sun Java conventions)
Follow the Java coding conventions (constants are in upper-case, class name starts with an upper-case, variables and methods start with a lower case, use camel case)
Use meaningful variable and method names
class member should be declared one by one (don't use int i, j, k; )
Use a single instruction per line (avoid stuffs like if(something) doSomething(); else {doSomethingElse1(); doSomethingElse2();} on a single line)
Avoid unnecessary usage of the static keyword (to the exception of constants)
Try to avoid coupling your code so much (try to make the minimum assumptions on how the rest of the code performs)
Add javadoc and comments in your code, this is always a good practice and it is of great help for you and others.
Your main cause for concern is that you not doing the updates related to JTextPane on the Event Dispatch Thread.
For a situation like this, when you really wanted to update a certain thingy from another Thread, always use EventQueue.invokeLater(...) or EvenQueue.invokeAndWait(), which can asynchronously (former)/synchronously (latter) update your request on the EDT, though care must be taken, as invokeAndWait() might can lead to deadlocks/run conditions if not used in the right sense.
Here is your updated code, that might work for your expectations. Hope you can modify the code, as per your liking.

Having been the one who answered your 2 previous questions on a similar task:
highlighting words in java
highlighting the word in java
and others not agreeing on my close vote, I decided to work on this a bit.
I have taken my latest example and edited to simplify where possible etc to make things more readable for you to understand, which in turn should help you understand how to go about simplifying your own.
I dont understand why you start a new thread to make words highlight slowly. Simply use my other examples and supply single letters rather than multiple letters and their timings to highlight, thus they will be highlighted individually. Or just make a method to do this work for you and iterate through those arrays as the letters and timings.
The below example uses an array of integers which hold the timings for words to be highlighted. It also contains an array for each individual word/letters we would like to highlight:
private int[] timingsArray = {1000, 900, 300, 1500};//word/letters timings
private String[] individualWordsToHighlight = {"Tes", " hiiii", " what", " happpn"};//each individual word/letters to highlight
In our start button we have a method to convert the above to single timings/letters for each individual letter for a letter by letter highlight:
//create Arrays of individual letters and their timings
final ArrayList<String> chars = new ArrayList<>();
final ArrayList<Integer> charsTiming = new ArrayList<>();
for (String s : individualWordsToHighlight) {
for (int i = 0; i < s.length(); i++) {
chars.add(String.valueOf(s.charAt(i)));
System.out.println(String.valueOf(s.charAt(i)));
}
}
for (int x = 0; x < timingsArray.length; x++) {
for (int i = 0; i < individualWordsToHighlight[x].length(); i++) {
charsTiming.add(timingsArray[x] / individualWordsToHighlight[x].length());
System.out.println(timingsArray[x] / individualWordsToHighlight[x].length());
}
}
Next there is a single Timer which will be started when start button is pressed which will highlight words/letters and restart itself with a new delay each time until all words/letters have been highlighted:
new Timer(1, new AbstractAction() {
#Override
public void actionPerformed(ActionEvent ae) {
if (count < charsTiming.size()) {
highlightNextWord();
//restart timer with new timings
((Timer) ae.getSource()).setInitialDelay(charsTiming.get(count));
((Timer) ae.getSource()).restart();
} else {//we are at the end of the array
reset();
((Timer) ae.getSource()).stop();//stop the timer
}
count++;//increment counter
}
}).start();
Hope this helps.

UPDATE
In response to your edited question.
Again the code complies fine for me, which brings me to the conclusion our java Runtimes differ and might be causing a problem. Mine is:
java version "1.7.0_10" Java(TM) SE Runtime Environment (build
1.7.0_10-b18) Java HotSpot(TM) 64-Bit Server VM (build 23.6-b04, mixed mode)
UPDATE 2:
As per your comment on your java version:
JDK 6, NetBeans 6.5.1
Have you tried:
final ArrayList<String> chars = new ArrayList<String>();
final ArrayList<Integer> charsTiming = new ArrayList<Integer>();
note i dont use <> anymore as Java 6 does not support the Diamond operator it would have to have the data type included i.e <Integer>.
I've been wondering if for example:
JTextPane chatTextArea = new JTextPane();
s.replaceAll(":\\)", emoticon());
public String emoticon(){
chatTextArea.insertIcon(new ImageIcon(ChatFrame.class.getResource("/smile.png")));
return "`";
}
can put a picture and a "`" everywhere ":)" is found. When I run it like this if s contains a ":)" then the whole s gets replaced just by the icon.
Is there a way to do it?
Here is a small example I made (+1 to #StanislavL for the original), simply uses DocumentListener and checks when a matching sequence for an emoticon is entered and replaces it with appropriate image:
NB: SPACE must be pressed or another character/emoticon typed to show image
