How to do the multiple-line String at JList? help!

i need some code to multiple-line String at JList.
i know that it is can be done by html code.
example:
<p>line1</p><p>line2</p>
but if i use that html code...
i face another problem to my JList..
it cannot set the font use the ListCellRenderer..
like:
public Component getListCellRendererComponent(
JList list,
Object value,
int index,
boolean isSelected,
boolean cellHasFocus)
Color newColor = new Color(230, 230, 230);
setIcon(((DisplayItem)value).getIcon());
setText(((DisplayItem)value).getChat());
setFont(((DisplayItem)value).getFont());
setBackground(isSelected ? newColor : Color.white);
setForeground(isSelected ? Color.black : Color.black);
if (isSelected) {
setBorder(
BorderFactory.createLineBorder(
Color.red, 2));
} else {
setBorder(
BorderFactory.createLineBorder(
list.getBackground(), 2));
return this;
all my JList will be html type...
i don't want that happen..can be another method to do that multiple-line String in JList??
i also need to set a icon image between string in the JList. anyone get idea??
i need ur help!
thank you.

I think you should create/override several methods like setText(String), setIcons(Icon[]), paintComponent(Graphics), getMinimumSize(), getPreferredSize(), etc.
I would like to code like below...:class MultilineLabel extends JLabel {
    private String[] text = null;
    private ImageIcon[] icons = null;
    public void setText( String newText ) {
        // It overrides JLabel.setText( String )
        // Tokenize newText with line-separator
        // and put each text into the 'text' array.
    public void setIcons( Icon[] newIcon ) {
        // It is similar to JLabel.setIcon( Icon ) method,
        // but it receives an array of Icon-s. Set these icons to 'icons' variable.
    public void paintComponent( Graphics g ) {
        // It overrides JComponent.paintComponent( Graphics ) method.
        super.paintComponent( g );
        if ( text != null && icons != null ) {
            int icon_x = 0;
            int text_x = 0;
            int y = 0;
            // draw customized content..
            for ( int i=0; i<text.length; i++ ) {
                // compute x and y locations
                // icon_x = ...
                // text_x = ...
                // y = ...
                // and draw it!
                g.drawString( text[ i ], text_x, y );
                icon[ i ].paintIcon( this, g, icon_x, y );
    public Dimension getMinimumSize() {
        int width = super.getMinimumSize().width;
        int height = ... // I think you must compute it with 'text' and 'icons'' arrays.
        return new Dimension( width, height );
    public Dimension getPreferredSize() {
        int width = super.getPreferredSize().width;
        int height = ...
        return new Dimension( width, height );
}I think that code-structure above is the minimum to implement your requirements. (Of course if you want to implement it :)
Good luck and let me know it works or not. :)

How to delete the logical lines in JTextArea

Hi all,
Now that I know how to find the logical line count in JTextArea as
I found the following in the forum.
public static int getLineCount (JTextArea _textArea)
boolean lineWrapHolder = _textArea.getLineWrap();
_textArea.setLineWrap(false);
double height = _textArea.getPreferredSize().getHeight();
_textArea.setLineWrap(lineWrapHolder);
double rowSize = height/_textArea.getLineCount();
return (int) (_textArea.getPreferredSize().getHeight() / rowSize);
I want to delete the 4th line to the last line and append ... at the 4th, if the getLineCount exceeds 3. Does any body know how to do so?
The intention is for the multiline tooltip as I just want to show
the first three logical line and ... if the string is too long.
Thanks
Pin

The code looks good to me. The only thought I have is that the y coordinate for the rowThree point is wrong and is referencing row four.
I've been playing around with using a JTextArea as a renderer for a JTable. I have it working so that "..." appear when the text exceeds 2 rows. Try clicking on "B" in the letter column and then the update cell button a few times to add text. My code is slightly different than yours.

How to delete the specified line in file?

How to delete the specified line in file? In case of deleting a specified line in a file, how to do?
Line 1
Line 2
Line 3
Line 4
Line 5
The case is a file including the above content. Now I wanna to delete the "Line 3" and how to realize the action in Java?

An alternative solution can be :
import java.io.LineNumberReader;
import java.io.IOException;
import java.io.File;
import java.io.FileReader;
import java.io.BufferedWriter;
import java.io.FileWriter;
import java.io.PrintWriter;
public class LineDeleter {
public static void main(String args[]){
try {
//suppose you want to delete line 3
     int lineToBeDeleted = 3;
     File f = new File("line.txt");
     long fileSize = f.length();
//Wrap the FileReader with a LineNumberReader. It will help you
//identify the lines.
LineNumberReader lnr = new LineNumberReader( new FileReader(f));
//Wrap the FileWriter object with BufferedWriter object. Create it with the buffersize
//equal to the file size.
     BufferedWriter bw = new BufferedWriter(new FileWriter(new File("line1.txt")),(int)fileSize);
//Wrap BufferedWriter object with PrintWriter so that it allows you
//to print line by line
PrintWriter pw = new PrintWriter(bw);
     String s=null;
     while ( (s=lnr.readLine())!=null ){
          System.out.println(s);
          int lineNumber = lnr.getLineNumber();
//match the line number
          if(! (lineNumber==lineToBeDeleted)){
               pw.println(s);
          pw.flush();
          lnr.close();
          pw.close();
     catch(Exception e){System.out.println(e);}
If you want you can rename the line1.txt to the original file name.
I hope this helps.Good luck!!!!!!

How to make the diagonal line in the swing table cell?

Hi all,
How to make the diagonal line in the swing table cell just like the link below?
http://61.132.17.188/webber/table.gif

One improvement.. To get a line that is neat, use a bit of Graphics2D
    public void paintComponent(java.awt.Graphics g)
        int w = getSize().width;
        int h = getSize().height;
        // draw a line between (0,0) and (w,h)
        g.setColor(getForeground());
        if (strTop == null)
            strTop = " ";
        if (strBottom == null)
            strBottom = " ";
            java.awt.Graphics2D g2 = (java.awt.Graphics2D)g;
          g2.setRenderingHint(java.awt.RenderingHints.KEY_ANTIALIASING,java.awt.RenderingHints.VALUE_ANTIALIAS_ON);
          //g2.setStroke(new java.awt.BasicStroke(14.0f));
        g.drawLine(0, 0, w, h);
        //the following lines will draw the two strings,
        //one above the top of the line and the above below it.
        g2.drawString(strTop, (w/2)+2, (h/2)-2);
        g2.drawString(strBottom, 2, (h / 2) + 2);
        //the x,y for drawString are only based on assumption.   //do necessary changes to suit ur needs.
    }Then create a TableCellRenderer and set it to the Table Header for ur table's 1st row.....
Cheers

How To Parse The Command Line?

Hello,dear. When I writing a C/S mode application,which performing download and upload files between the FTP server and the clients, I encountered the problem of parsing the command line.
I intend to download file from the server side ,using this following format ,which is composed by four arguments:
ftp>receive server's IPaddress portnumber filename
The problem is I don't know how to parse the command line and store them to some objects and using it.
I'm right here waiting for the nice problem-shooter.
Thanks for reading my poor expression.

In your console application main class
public static void main(String[] args)
// code
args is a sting array with the command
line itemsI think you missed the point or forgot the ":-)". This is the "Socket", not the "New to Java" forum.

Hi,
A possible method is:
Get all fields of the form
    CALL METHOD request->get_form_fields
      CHANGING
        fields = table_fields.
loop over the fields
    LOOP AT table_fields INTO wa_fields.
test the name of the field
      CASE wa_fields-name.
        WHEN 'test'.
retrieve the value of the field
          test = wa_fields-value.
endcase
endloop.
