Overlapping ListItems in JList

Hi,
is it possible to overlap the listitems in a JList ? Want to use a JList as an layout edit there overlapping items can occur as fault design. Is that possible ? Haven't found a way.
Greetings
Oli

I dont know "overlop" meaning...Could you tell it clearly??
If you want to overlop one JList on the other, I have some means to do that work, I have a project resolve this work just in time. You can communicate with me: [email protected]

  • Overlapping elements in JList

    Hi,
    I want to develop a design tool which allows the editing and visualization of elements which are ordered linear. Each element has a start and end address so it is possible that elements overlap. This is an error case an should be visualized. First I thought to use JList to display the elements. But I think its quite difficult to realize the overlapping elements (JList entries). Is it possible with JList or it's better to draw gui representation myself ?
    Thanks
    Oli

    Thanks for your post....I have already my own list cell renderer by implementing ListCellRenderer interface. In the getListCellRendererComponent I return a JLabel for each list item with different height (to visualize sizes). I can't see the possibility in this method to realize the overlapping. I get only the index no positions.

  • Empty JList box

    Hi all,
    I want to add a JList box that is empty at compile time and also that has an actionselectionlistener on it to check for changes to the list (once there are items in the list of course). For some reason the technique isnt the same for creating a blank JList as it is for creating a blank JComboBox.
    This is what I have for my JComboBox
    myCmb = new JComboBox()    //globalVariable
    myCmb.addActionListener(this);
    JPanel inputPane = new JPanel();
    inputPane.add(myCmb);
    getContentPane().add(inputPane);
    show();That works perfectly. However the code below doesnt.
    myList = new JList()    //globalVariable
    myList.addListSelectionListener(this);
    JPanel inputPane = new JPanel();
    inputPane.add(myList);
    getContentPane().add(inputPane);
    show();I have no idea why it isnt working.
    I want the blank list box big enough to show 7 items in it (even though it is blank) and also about the same width as it is in length.
    Thanks :)

    Hi
    thanks for the reply :)
    The problem I believe is with the addListSelectionListener. When I try to compile it I get an error saying:
    Error(49,9): method addListSelectionListener(client.GUI) not found in class javax.swing.JList
    These are my imports:
    import java.awt.*;
    import java.awt.event.*;
    import javax.swing.*;
    import javax.swing.event.*;
    import java.util.*;I appreciate you being willing to test my short code, here it is below:
    package client;
    import javax.swing.*;
    import java.awt.*;
    import java.awt.event.ActionEvent;
    import java.awt.event.ActionListener;
    import javax.swing.event.*;
    import java.util.*;
    public class GUI extends JFrame implements ActionListener{
    JList listItems;
        public GUI() {
            super("my GUI");
            setSize(450,300);
            setDefaultCloseOperation(EXIT_ON_CLOSE);
            getContentPane().setLayout(new GridLayout(4,1));
            listItems = new JList();
            listItems.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
            listItems.setSelectedIndex(0);
            listItems.addListSelectionListener(this);
            JScrollPane listScrollPane = new JScrollPane(listItems);
            JPanel inputPane = new JPanel();
            inputPane.add(listItems);
            inputPane.add(listScrollPane);
            getContentPane().add(inputPane);
            show();   
        public void actionPerformed(ActionEvent event){
        Object source = event.getSource();
        public static void main(String[] args) {
            GUI gUI = new GUI();  
    }The above code is only supposed to display a blank list box, but it doesnt comile due to the error message written above.
    I know it seems strange to want to display a blank listbox but the reason why is because there will also be a populated combobox and depending on what the user select from the combobox the list box will then get populated. This is why I want a blank list box to start with :)
    Thanks again for your help mate

  • How can i change the order of  elements in a JList ?

    Hi,
    i would like to know if it is possible to change the order of elements in a JList ? Maybe i could use drag and drop to do this ?
    Thanks for answering.

    The simplest way is probably to implement ur own listmodel and then supply the listitems in the order u want. Example:
    class MyListModel
              extends AbstractListModel
              implements ContactListListener {
    public int getSize() {
    return listitemcount;
    public Object getElementAt(int index) {
    //here u return the item for the index at the list
    //if u for example have an array of strings
    //which u wanna have listed in reversed order (reversed to
    //the order in the array, u could do
         return myarray[getSize()-index];
    }

  • Diferent font in JList

    hi is there a way to make each element in a JList to a different font. i am making a FontDialog and i would like each font name in the list to be the font of that font... like in MS word.
    many thanks
    David

    Use a customized ListCellRenderer. The following outlines one possible way of doing it:
        // Use instances of this class as items in your list:
        class FontListItem {
            private Font    font;
            public FontListItem(Font font) {
                this.font = font;
            public String toString() {
                return font.getName();
            public Font getFont() {
                return font;
        // The ListCellRenderer for your JList:
        class FontListRenderer extends DefaultListCellRenderer {
            public Component getListCellRendererComponent(JList list,
                                                          Object value,
                                                          int index,
                                                          boolean isSelected,
                                                          boolean cellHasFocus) {
                JLabel renderer = (JLabel)super.getListCellRendererComponent(
                        list, value, index, isSelected, cellHasFocus);
                if( value instanceof FontListItem ) {
                    renderer.setFont( ((FontListItem)value).getFont() );
                return renderer;
        // Example of use:
        FontListItem[] listItems = ...
        JList list = new JList(listItems);
        list.setCellRenderer(new FontListRenderer());

            for(int i = 0; i < images.length; i++)
                try
                    String path = "images/" + fileNames + ".gif";
    URL url = getClass().getResource(path);
    images[i] = ImageIO.read(url);
    catch(MalformedURLException mue)

    catch(IOException ioe)
    System.out.println("read: " + ioe.getMessage());
    public static void main(String[] args)
    JFrame f = new JFrame();
    f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    f.getContentPane().add(new JScrollPane(new ImageList().list));
    f.setSize(400,400);
    f.setLocation(200,200);
    f.setVisible(true);
    class ImageRenderer extends DefaultListCellRenderer
    public Component getListCellRendererComponent(JList list,
    Object value,
    int index,
    boolean isSelected,
    boolean cellHasFocus)
    // for default cell renderer behavior
    Component c = super.getListCellRendererComponent(list, value,
    index, isSelected, cellHasFocus);
    // set icon for cell image
    ((JLabel)c).setIcon(new ImageIcon((BufferedImage)value));
    ((JLabel)c).setText("");
    return c;
    Here is netbeans project:
    [http://www.mediafire.com/?nl29dl4tteu]
    Note: If you check image 2.gif inside the src/images dir you will found that it is an animated gif but JList is displaying it as static image.
    Bedla if you want both image and text then create a class like thisclass ListItem {
    private BufferedImage image;
    private String value;
    public ListItem(
    BufferedImage c, String s) {..}
    public Color getImage() {..}
    public String getValue() {..}

  • Images like items of Jlist.

    Salut,
    I would like to make a Jlist who will have images(small size) like items instead of the usual string.
    All of your help and advices are welcome.Thanks.

    In The API for JList check out:
    public void setCellRenderer(ListCellRenderer cellRenderer)also check out
    javax.swing
    Interface ListCellRenderer
    here is a rather dud one I was using:
    public class PicListCellRenderer extends JLabel implements ListCellRenderer
         final ImageIcon picIcon = new ImageIcon(this.getClass().getResource("images/Pic16.jpg"));
         final ImageIcon selectedIcon = new ImageIcon(this.getClass().getResource("images/GirlD16.jpg"));
         public Component getListCellRendererComponent( JList list,
                                       Object value,            // value to display
                                       int index,               // cell index
                                       boolean isSelected,      // is the cell selected
                                       boolean cellHasFocus         // the list and the cell have the focus
              String s = value.toString();
              setText(s);
              if( isSelected )
                   this.setIcon( selectedIcon );
              else
                   this.setIcon( picIcon );
              if (isSelected)
                   setBackground(list.getSelectionBackground());
                     setForeground(list.getSelectionForeground());
              else
                   setBackground(list.getBackground());
                   setForeground(list.getForeground());
              setEnabled(list.isEnabled());
              setFont(list.getFont());
              setOpaque(true);
              return this;          
    }Kind of Dud only has 2 Pics, but I guess it shows the idea
    then have:
    JList Fred = new JList();
    Fred.setCellRenderer(new MyListCellRenderer());You can do all sorts of things with these.
    I don't think you could just set the ListItems to Images, but here I set them to a JLabel with an ImageIcon on it...

    I have a jList where i represent an image and a text, using my own ListCellRenderer . It looks like the following
    public class JListImageRenderer extends JLabel implements ListCellRenderer{
    public Component getListCellRendererComponent(JList list, Object value, int index, boolean isSelected, boolean cellHasFocus){
            String text = "";
            ImageIcon icon = null;
             //.....some code here.....//
    //       and finally
            setText(text);
            setIcon(icon);
            setCursor(new Cursor(Cursor.HAND_CURSOR));
    //        addMouseListener(new MouseListe(){
            return this;
        }My questions are:
    i)is there any way of adding a second image? I need my list to display two images and the text at every row ,
    instead of a single image + text. Obviously i need a different implementation of ListCellRenderer but
    which would be that implementation?
    ii) why setCursor(new Cursor(Cursor.HAND_CURSOR)); hasn't got any effect on the mouse pointer when i hover over the list rows?
    thanks in advance

    As you can see the text of each JLabel is not being highlighted when you click on the corresponding row

  • JList - CellRendering

    hi,
    i want to design my list item with background image,font faces and sizes when it selected by using Html tags.
    for example,
    // Contacts(userName, userIcon)
    Contacts contacts[] =
    new Contacts("<html> <table width= '75%' height='57' border='1'><tr> <td align='center' background='resources/id.gif'><img src='resources/id.gif' width='22' height='20'>Username", resources/id.gif"),
    JList contactsList = new JList(contacts);
    i got partially.. i got table data but i couldn't see the images in that.. instaed of images, it shows image broken link. but the same image, i can assign for the userIcon.
    why i am including table here means, i want to display the contactitems with all information like Name, image, place when it selected.
    and another one, how i implement this to display at Listitem selected.
    if anyone know this, pls tell me
    regards,
    Gokulakrishnan

    <img src='resources/id.gif' ..... >First, this URL syntax may be wrong for your local file.
    You should call:
    contactList.setCellRenderer(new MyJEditorPaneRenderer());
    As the name suggest, you should write a ListCellRenderer whose method returns a
    JEditorPane component which has called its setPage() for your html string which,
    in turn, is contacts[index].

  • How can I fix left pane text overlap in iCal Day view?

    In "Day" view, the items in the left hand (list) pane in iCal are overlapping, obscuring the bottom 1/3 of each line of text. It is as if the table cells are too close together vertically. How do I fix this?

    Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
    *Don't make any changes on the Safe mode start window.

  • Awesome systray is not showing all icons, perhaps overlapping widgets?

    I have a problem with my Awesome configuration that results in some of the icons being missing or partially missing from my systray. I suspect this is because of some overlapping, since they are partially hidden. You can see the problem in the top right corner.

    First of all, did you check the wiki and forums? We'll help you, but you have to try to fix it yourself first.
    You will need to provide more info if you want help.
    Did you set up Gnome to force fallback mode?
    Did you look at the Gnome wiki article? There's a few sections that sound like what your looking to do, but the examples are USING OTHER WM's. They still might be able to point you in the right direction.

  • MDI JTable Overlap Area Repaint Problem

    Hi all,
    I have a problem for my application in MDI mode.
    I open many windows (JInternalFrame contain JTable) under JDesktopPane. Some of the windows are overlapping and when they receive update in the table, it seems repaint all of the overlapping windows, not only itself. This make my application performance become poor, slow respond for drap & drop an existing window or open a new window.
    To prove this, i make a simple example for open many simple table and have a thread to update the table's value for every 200 mill second. After i open about 20 windows, the performance become poor again.
    If anyone face the same problem with me and any suggestions to solve the problem ?
    Please help !!!!!

  • Unity Connection 7 with overlapping extension

    Hello everybody,
    I'm deploying a CUCM 7.1.3 + Unity Connecion 7.1.3 to a customer, and I have a doubt when using overlapping extension. As it's a large environment, he has overlapping extension number in his multiple sites. For example, both SiteA and SiteB have the extension range 8XXX. In CUCM I have configured some translations patterns, so that an user from SiteA should dial 118XXX in order to reach SiteB, and an user in SiteB should dial 218XXX in order to reach site A. And each site has its own line partition to extension numbers. And everything works fine...
    But these users are all in the same Unity Connection Server. So I would have users from SiteA and SiteB with the same extension in Unity Connection, and I can't do that. What I know can do is to configure some partitions from SiteA and SiteB in CUC, and put each subscriber in one partition, right?
    But when a user wants to reach the voice mail to get his messages, how Unity Connection knows from which location is he?
    Please, anyone could advise me how can I proceed with this configuration?
    Thank you!!!

    Hello,
    I workarounded my problem creating multiple VM Profiles, and assigning a diferent Voice Mail Box Mask for each. And in Unity connection I created a alternate extension for each user.
    For example... the extension 6000 from SiteA has the VM Profile VM_SiteA, which has the voicemail box mask 11XXXX. And this user in Connection has the alternate extension 116000. And the extension 6000 from SiteB has the VM Profile VM_SiteB, which has the voicemail box mask 21XXXX, and this user has this number as alternate extension as well (216000)... It works fine like this.
    But actually I haven't tested the MWI... If I have a translation pattern in CUCM that translates 11XXXX to XXXX (in partition from SiteA), and another 21XXXX to XXXX (in partition from SiteB), and configure the MWI extension in Connection to be 11XXXX and 21XXXX, will it work? Have anyone already tested this?
    Thank you very much!!!
