Locking the JText Area

class UserInterface extends JFrame { 
 
private JTextArea txtWallArcher;
 
// constructor

 
UserInterface() {
 
WallInterface =  new JPanel();
txtWallArcher = new JTextArea ("  Archer  ");
WallInterface.add (txtWallArcher);
this.add (WallInterface);
this.setLayout (new GridLayout (1,3,4,5));
   

   
}

How can I lock the j text area so that the user cannot edit the text?
Also how can I make "Archers" in bold?


Thank you very much for your help!

ta.setEditable(false);
(where ta = your textArea)

> Also how can I make "Archers" in bold?
ta.setFont(ta.getFont().deriveFont(Font.BOLD));
note: this will change the font for all the text in the textArea

Thank you very much for your help.

I have another question. Would it be possible to set the size of a JTextArea? Like a set size of number of characters

For example if it was set to size 5 then it would looks like the the following examples [_____] <-- that is the JTextArea

[1____]
[23___]
[422__]
[42444]

you can:
set line wrap
change the font to monospaced
use FontMetrics to set the preferredSize

something like this

import javax.swing.*;
import java.awt.*;
class Testing extends JFrame
{
  public Testing()
  {
    setLocation(300,200);
    setDefaultCloseOperation(EXIT_ON_CLOSE);
    JTextArea ta = new JTextArea("12345");
    ta.setFont(new Font("monospaced",Font.PLAIN,12));
    ta.setLineWrap(true);
    JPanel p = new JPanel();
    p.add(ta);
    getContentPane().add(p);
    setVisible(true);
    FontMetrics fm = ta.getGraphics().getFontMetrics();
    ta.setPreferredSize(new Dimension(fm.stringWidth(ta.getText()),fm.getHeight()*3));
    pack();
  }
  public static void main(String[] args){new Testing();}
}

this will give you 3 rows.
I don't know whether you want a scrollpane, if so, it will cause problems
when the vertical scrollbar kicks in.
if you want to restrict it to e.g. 3 rows, you can add set the 'document' so
that it only accepts 15 characters (5 * 3 rows)
