Strings and fonts

Hello, guys, i'm new to this forum (:
Basically my situation is the following:

i wanna present a certain text on the screen, and every time i see a certain word (let's say 'cat', for this matter) i want it to be in bold. or underlined. or highlighted.

As far as i know i can't do it with a simple String variable.

I tried using a JtextArea and set it's font to a certain font, but the problem with that is the simple fact that this changes the *whole* text, and i only want some of it to be in bold.

any suggestions? thanks!

do you want this done in a JLabel? or something else?

well basically i'm hoping to do it in a JTextAea, or something like that, because i want the user to be able to copy-paste the result... wow, ur quick with the answer, lol

why would it matter if it is in bold if you wanna copy paste etc
anyway im pretty sure you can subclass JTextField and make its font bold or whatever

well, basically i'm trying to build like a mini google system
let's just say i wanna read from a txt file on my computer, show the file on the JTextArea or whatever, and every time i see a certain word (provided by the user) to make it bold. or highlighted. or anything like that.
but you know what, if you have a solution for JLabel, i'd be happy to accept that as well, i really need anything that can help.

nope we can make this work in JTextArea i am sure, give me an hour :)

Take a look at the JEditorPane class.

hey norm, i already did, but i'm having the same problem... can i change only sone of the text in the JEdidorPane? thanks!

Yes you can. Check out the tutorials.

yea ok got along! thanks, guys! :)

best I could do with JTextArea but looks like you got a solution anyhow

Code:

---

import java.awt.Font;

import javax.swing.*;
import javax.swing.text.BadLocationException;


public class HighLights {
        private JFrame myFrame;
        private String yourFileContents;
        private JTextArea yourTextToBold;
        public HighLights()
        {
                myFrame=new JFrame("highlights");
                myFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
                myFrame.setSize(500,500);
                String yourFileContents="Jimmy was here Jimmy";
                String search=yourFileContents;
                String match="Jimmy";
                if(yourFileContents.indexOf(match)!=-1)
                {
                        yourTextToBold=new JTextArea();
                        yourTextToBold.setText(search);
                        yourTextToBold.setFont(new Font("",Font.BOLD,20));
                        yourTextToBold.select(yourTextToBold.getText().indexOf(match,0),match.length());
                }
                myFrame.getContentPane().add(yourTextToBold);
                myFrame.setVisible(true);
               
        }
        public static void main(String[]args)
        {
                new HighLights();
        }
}

A JTextArea can't do it; the code snippet above sets the font for the entire text to a boldfaced font. You either need a JTextPane or JEditorPane or you have to use the html text capabilities of some other JComponents.

kind regards,

Jos

ps. maybe something acceptible can be hacked in a JTextArea using special Highlighters ...

I know what you are saying and I agree but his requirement was not limited to bold font he also would have accepted highlighted text
