Strings and fonts

[TheGoodGuy]

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?

[TheGoodGuy]

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

[al_Marshy_1981]

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

[TheGoodGuy]

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.

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

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,

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
