How to center JList items

Hi,
I want to center my Jlist item instead of leave them in the left like usual. My List contains pictures and for the beauty of the design it's better to have the image in the center of each cells. How to do it?
thanks.

Do you know how to make a JLabel which contains a centred icon? Now make a ListCellRenderer that uses one of those to render your images in the JList.

How to save JList items!

hello,
i m creating a class that has three JList components.
My problem is how to save the each JList items into a seperate logfile(ie. text file).

More info required:
What are in the JList? Strings? Custom objects?
Do you know basic file IO?
http://java.sun.com/docs/books/tutorial/essential/io/index.html
What you will need to do is get the model, ilterate over each element, then write that element out. If the element is a string, then that is easy, just create a FileWriter, and write the string, followed by a new line.
If it is a custom object, then the task is harder, and you need to decide how that object should be represented.
If you are after a computer readable view of the model, rather than a human readable, which can easily be read by Java back into a ListModel, then you want to look at XMLEncoder and XMLDecode, or the Serializing Objects tutorial.

I don't even know how to center one item in one wiondow. HELP!

OK, I can't even do the simplest layout in the whole Universe work with Java:
Centering one component like a button or a label centered vertically and horizontally.
Can somebody show me how to accomplish what I want with the follwing program?
import java.awt.*;
import java.awt.event.*;
import java.applet.*;
public class Sheep000a extends Applet
implements ActionListener {
    int sheepNum;
    Button button1;
    Panel panel1;
    public void init() {
        panel1 = new Panel();
        panel1.setBackground(new Color(0,255,255));
        setBackground(new Color(0,255,255));
        button1= new Button("Hi, I'm a Java Button. Do you see me?");
        panel1.add(button1);
        add(panel1);
        button1.addActionListener(this);
        resize(500,300);;
        setVisible(true);
    public void actionPerformed(ActionEvent e) {
}As it is, the button is centered horizontally, but not vertically. I want it centered even when the window is resized.

panel1.setLayout(new BorderLayout());
you'd have to read some articles about layout
management in swingHmm . . . I've browsed through sections on layout. I just can't get things work.
I cahnged my program to the following per your sugestion:
import java.awt.*;
import java.awt.event.*;
import java.applet.*;
public class Sheep000b extends Applet
implements ActionListener {
    int sheepNum;
    Button button1;
    Panel panel1;
    public void init() {
        panel1 = new Panel();
        panel1.setLayout(new BorderLayout());
        panel1.setBackground(new Color(0,255,255));
        setBackground(new Color(0,255,255));
        button1= new Button("Hi, I'm a Java Button. Do you see me?");
        panel1.add(button1);
//      panel1.add(button1, BorderLayout.CENTER);
        add(panel1);
        button1.addActionListener(this);
        resize(500,300);
        setVisible(true);
    public void actionPerformed(ActionEvent e) {
}It compiles but the button is still at the top.
Changing panel1.add(button1);
to the one below doesn't make any difference.
resize(500,300) does not work anymore either.
Is this my computer specific problem?

Rendering JList items instantly

hi friends
I wanna know how to rendering JList items instantly without selecting any item,so the rendering of the item has to be automatically.
thank you very much

Well how does the icon change? Normally changes to the data are done by updating the model, in which case the list will get painted automatically.
If you need further help then you need to create a [Short, Self Contained, Compilable and Executable, Example Program (SSCCE)|http://homepage1.nifty.com/algafield/sscce.html], that demonstrates the incorrect behaviour.
Don't forget to use the Code Formatting Tags so the posted code retains its original formatting. That is done by selecting the code and then clicking on the "Code" button above the question input area.

How to center the text displayed in a JList

Hi,
The width of the JList display area is wider than the text displayed. I tried to center the text displayed to make it look nicer. I had tried using "setAlignmentX(Component.CENTER_ALIGNMENT)" in my own ListCellRenderer class but did not work. Any idea how to center the text?
Fai.

Yes, I am using JLabels in my renderer and the following is the code:
public class MyCellRenderer extends JLabel implements ListCellRenderer {
     private static final Color HIGHLIGHT_COLOR = new Color(0, 0, 128);
     public MyCellRenderer() {
          setOpaque(true);
          setIconTextGap(12);
     public Component getListCellRendererComponent(
          JList list,
          Object value,
          int index,
          boolean isSelected,
          boolean cellHasFocus)
          String entry = (String)value;
          setText(entry);
          setFont(new Font("Ariel", Font.BOLD, 18));
          setAlignmentX(Component.CENTER_ALIGNMENT);
          if(isSelected) {
               setBackground(HIGHLIGHT_COLOR);
               setForeground(Color.white);
          } else {
               setBackground(Color.white);
               setForeground(Color.black);
          return this;
Can you point out where to implement the centering logic?
Thanks,

Profit center line item report

Hello All,
A sales order is created with reference to a service order, now when I see Profit center line items, the function area available in Service order is differ from the function area displaying with sales document number in profit center line item report. Can anyone please tell me where could be the problem.
Full points will be awarded for the answer.
Thanks & Regards
Srini

Hi,
what SAP release do you have ?
Normally the derivation of the functional area is made with the following logic:
1) manually entered
2) FI-Substitution (calling point 5 or 6 since ERP2004)
3) cost center
4) cost element
Please see also SAP note 106180 of how to correct wrong functional areas in PCA.

Profit center line items KE5Z - order missing - GLPCA-AUFNR

Hi folks,
could anybody give me an advice how to arrange that the order will be displayed in the KE5Z report?
Field GLPCA-AUFNR
Thanks a lot.
Regards
Edited by: Peter Jankech on Jun 4, 2008 1:41 PM

Sorry for unclear set question.
I know how to edit a layout.
The problem is, that the field GLPCA-AUFNR is initial, therefore in KE5Z-Profit center line items the field order is empty.
Is there any customizing setting or SAP-Note, which ensures that the field GLPCA-AUFNR is filled?
Thanks

How to do Commitment item carryforward (Fund Management) ?

Dear experts,
Please guide me how to do commitment item carryforward.
I've read thought SAP help, it said I need to do commitment item carryforward.
But I have no idea, what's the transaction code, what parameter to fill in..
Kindly guide me or send me related document...please....
[FM Newbie]

T code : CJCF - Carry Forward Commitment
Parameters: - Carrying Forward Commitments
To carry forward a commitment to the first period of the following fiscal year, proceed as follows:
Choose Accounting ® Controlling ® Cost Center Accounting ® Year-end closing ® Commitment carried forward.
Enter the relevant cost center(s).
Select or deselect the following indicators:
Test run
If you select Test run, the system carried forward the commitment, but does not update the results.
Detail lists
If you activate Detail list, the system displays the results of the commitment carried forward. The results list shows which values were carried forward.
You should activate the Detail list together with the Test run. This ensures that you can check the results of the test run.
Reversal
The Reversal indicator controls whether data that has already been carried forward should be reversed again or not.
If you have large amounts of data to process, it is advisable to execute the commitment carry-forward using background processing. This means you can process data at times of minimal system usage.
Choose Program Execute in background.

FM to get Fund/Fund Center/Commitment Item- Item level total (FMBB)

Hi,
1. How to get line item level total of of document created in Fund Management with FMBB tcode? Is there a Function Module for the same? The data stored in FMBH/FMBL are period wise.
2. Is there any way we can change Prepost amount of a FM document on fund/fund center/commitment item level ?

Hi Naveen,
check the following tables
1. FMIFIHD - FM Header table in Fund management
2. FMIFIIT - FM Line item Table in Fund management
3. FMIT - Totals table for fund management
4. FMIA- Actual Line item table for Fund management
For the second point, i think you need to reverse the origin document and repost it with correct amount. There is no other option.

Dynamically changing size of JList items?

Hello!
I'm working on an application which kind of revolves around a JList with a custom ListCellRenderer. Now, it all works rather good as it is, but I want the selected JList item to show more detailed information about the selected value, and thus I need it to be bigger then the not selected items. The thing is that no matter what I do I can't seem to make the JList adopt to the new size of the selected item, which results in only half of the stuff in the selected item being shown.
Is there any way to do this it would be great! (I bet there is some really simple way which I have simply overlooked.)
And, fyi: The component returned by getListCellRendererComponent is a JPanel which consists of three JLabels using a GridLayout. The selected component is generally the same, but with an extra row in the GridLayout.
Any help/suggestions will be greatly appreceated!
Yours, Jiddo.

I have tried with a couple of different layout managers, and none of them (except for this one) seems to offer me the layout I need. Also, I have tried making it return different instances depending on if it is selected or not. The non-selected one has only one row in the layout while the selected has two. Here is a screenshot of how it looks:

How to center menu and add spacing between buttons?

Here is my site: http://lauraportfolio.hostoi.com/index.html (If you are using Google Chrome you can right click and select "view page source" to see the html of the page)
See how the menu button are justified the left of the light pink menu bar? How can I put them in the center?
I would like to know how to center the menu, and then add spacing between the buttons.
At one point I added spacing between the buttons using CSS padding, but when I did that the last menu button, "Graphics" ran off the pink menu bar and became invisible and all kinds of crazy ugly stuff!
Below is what I beleive to be all of the CSS styling for the menu:
#menubar
          width: 900px;
          height: 72px;
          padding: 0;
          background-color: transparent;
          background-image: url(transparentpink.png);
          background-repeat: repeat;
ul#menu, ul#menu li
{ float: left;
margin: 0;
padding: 0;}
ul#menu li
          list-style: none;
          padding-right: 0px;
          padding-left: 0px;
          margin-right: auto;
          margin-left: auto;
ul#menu li a
          letter-spacing: 0.1em;
          display: block;
          float: left;
          height: 37px;
          text-align: center;
          color: #f0dbca;
          text-transform: none;
          text-decoration: none;
          background: transparent;
          font-family: bonvenoCF, verdana, Geneva, sans-serif;
          font-size: 150%;
          font-style: normal;
          font-weight: normal;
          font-variant: normal;
          padding-top: 29px;
          padding-right: 26px;
          padding-bottom: 6px;
          padding-left: 26px;
ul#menu li a:hover, ul#menu li.selected a, ul#menu li.selected a:hover
          color: #F0DBCA;
          background-color: #F1836A;

PART 1
So as long as the width of the buttons plus the padding doesn't go over 900px it won't run off the page?
Right.   The "box model" in CSS works like this:
width + padding + border = actual visible/rendered width of box
height + padding + border = actual visible/rendered height of box.
PART 2
And do you know how I can center the whole thin instead of it being left-aligned on the menu bar?
You can't center floated menu items. The best you can do is make your menu fit the entire width of the container (or as close as you can) as described in PART 1 above.
To center your #menu container, use margin:0 auto;
To center text, use text-align:center on the #menu li a.

Double click for JList items selection

I would like to select JList items only by double clicking on them. I can write a mouse listener for detecting double clicks by my own (and handle it afterwards), by please tell me how to turn the default behavior off (selecting items by clicking one time).
Thanks in advance
Marek

I would like to select JList items only by double clicking on them. Well the standard is to select or highlight on a mouseClick or by using the arrow keys on the keyboard.
Then once you have a selected item you can perform and Action on the item by double clicking or by using the enter key. Remember you should always be able to use either the keyboard or the mouse to perform any given function.
This posting shows my solution for the above scenario:

Highlight a word within a JList Item

I would like to highlight a word red within a JList item. For example, a user has a number of words to select from such as can or will. I would like them to select that word and any entries within the list I would like highlighted. I ONLY want the word within a JList item though and not the whole JList item. I know how to do this with a TextField but am having trouble doing this within a JList. Any help would be greatly appreciated.

Use html syntax to set color/size of a list item. Try this simple example:
import java.awt.*;
import javax.swing.*;
class Testing extends JFrame {
public Testing() {
 String [] list = {
 "<html><body>Black Black Black",
 "<html><body>Red Red Red ",
 "<html><body>Blue Blue Blue"
 setDefaultCloseOperation(EXIT_ON_CLOSE);
 JPanel panel = new JPanel(new BorderLayout());
 JList jlist = new JList(list);
 JScrollPane spane = new JScrollPane(jlist);
 panel.add(spane);
 getContentPane().add(panel);
 setSize(200,200);
public static void main(String[] args){
 new Testing().setVisible(true);
}
