JTable disappears

Hi All,
I am using a JTable on a JPanel which is on a JTabbedPane. I also have JLists on the JPanel where users make certain selections, I filter the data displayed on the JTable based on the selection made by the users on the JList and redisplay the JTable. This the code i use to clear the JPanel and readd the new Table
     private void addTableToGUI(ITableModel aTableModel) {
          //this is the panel that has the JTable
          panelWithScroll.removeAll();
     if (aTableModel != null) {
          GUITableSorter sorter = new GUITableSorter(aTableModel);
          //create the JTable (view) with the model
          JTable aTable = new JTable(sorter);
          aTable.setPreferredScrollableViewportSize(new Dimension(350, 120));
          aTable.setAutoResizeMode(JTable.AUTO_RESIZE_ALL_COLUMNS);
          sorter.addMouseListenerToHeaderInTable(aTable);
          //create the JScrollPane
          scrollPane = new JScrollPane(aTable,
                    JScrollPane.VERTICAL_SCROLLBAR_ALWAYS,
                    JScrollPane.HORIZONTAL_SCROLLBAR_AS_NEEDED);
          panelWithScroll.add(scrollPane);
          panelWithScroll.repaint();
          mainFrame.repaint();Even though i repaint the frame and the panel the JTable doesnt show, but when i slightly resize the Frame the JTable shows up...
Any suggestions to solve this issue?
Thanks,

This the code i use to clear the JPanel and readd the new TableDon't create a new JTable. Just replace the TableModel.
TableModel model = .... // create your table model with new data here
table.setModel( model );

  • Vertical ScrollBar for JTable disappears when trying to scroll!

    Hi!
    I have 2 JTables and these are in a JScrollPane. I need to add a Vertical ScrollBar in such a way that when the number of rows increases, the scrollbar will scroll both the table's data.
    I am not using the Vertical ScrollBar of the ScrollPane instead i have added a JScrollBar to the two Panes( i.e. scrollPane.setVerticalScrollBar() ). This works fine.
    But when I remove the columns from the right JTable , i.e. I have only one JTable left, the Vertical scrollbar disappears inspite of the number of rows being the same.
    I have tried setting ViewPortView etc. but nothing works.
    Please help!

    Remember that was a test. It tells us the iPhoto is essentially sound and the issue is within that main Library.
    Next move is to try repair that library.
    Option 1
    Back Up and try rebuild the library: hold down the command and option (or alt) keys while launching iPhoto. Use the resulting dialogue to rebuild. Choose to Repair Database. If that doesn't help, then try again, this time using Rebuild Database.
    If that fails:
    Option 2
    Download iPhoto Library Manager and use its rebuild function. (In early versions of Library Manager it's the File -> Rebuild command. In later versions it's under the Library menu.)
    This will create an entirely new library. It will then copy (or try to) your photos and all the associated metadata and versions to this new Library, and arrange it as close as it can to what you had in the damaged Library. It does this based on information it finds in the iPhoto sharing mechanism - but that means that things not shared won't be there, so no slideshows, books or calendars, for instance - but it should get all your events, albums and keywords, faces and places back.
    Because this process creates an entirely new library and leaves your old one untouched, it is non-destructive, and if you're not happy with the results you can simply return to your old one.

  • How to design multi screen application?

    Hello Everybody,
    I am building a BI application(AIR) that will run on desktop(resolution is not fixed) as well as on device like ipad and variety of mobile phones.
    But I am having trouble in making its design cross resolution. Please suggest me a proper way to build the app flexible to fit to any screen.
    Thanks in advance

    When a user clicks in a row in the JTable, I want that the JTable
    disappears and shows all the info of the row selected. Once my user
    finish the edition of this row the will return to the jtable and will show
    the information updated.A more common design would be to display a modal dialog with the row information and then update the table when the dialog is closed.

  • Help with JTable - content of cell disappears when selected

    Hello,
    I have a jTable and I have created a custom cell renderer. It does what it's supposed to do (which is set the background color of all cells with null or "" value to red - as an indication to the user that b4 proceeding he/she has to fill in this cells). The problem is that when I select a red cell, it becomes white and the text value it contains disappears. When I double click I can start typing in a new value.
    I would appreciate any hint why this happens? Ideally I would like the cell to keep its color when clicked or double-clicked and its value, and only when i'm done editing its content and it's not null or empty string to become white.
    I'm including majority of my code (some automatically generated code from Netbeans is not included).
    Thank you very much,

    Ideally I would like the cell to keep its color when clicked or double-clicked Not sure why is changes color when you click on the cell.
    But when you double click the editor is invoked, which is a JTextField and its background is white by default.
    The code you posted doesn't help because its not executable.
    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.
    And don't post NetBeans generated code, because we don't use IDE to write GUI code.
    Also, why did you create a custom TableModel. The DefaultTableModel will store your data for you.

  • When resizing columns in JTable the last columns disappear

    I have a problem. I created a JTable and I set the AutoResizeMode to AUTO_RESIZE_NEXT_COLUMN in order for the columns to fill the whole panel. I added the table to a JScrollPane. when I resize the columns, the other columns start to adjust in size to fit the data grid, but it gets to a point where the columns scroll out view. is there a way to stop the other columns from moving when I resize one of the columns. I dont want the horizontal bars to show.

    When your mouse pointer is over a movable area, the mouse pointer should turn into a double-arrow. If you notice that after dragging and releasing the mouse, the mouse pointer ''stays'' a double arrow, try positioning the mouse pointer where you want the new boundary and click again. The mouse pointer should change back to a standard pointer.
    Does that work?
    (This suggestion is based on behavior I've seen with some Infragistics ASP.Net controls in IE8.)

  • Last few Columns disappear in JTable

    Hi Guys,
    I have put a JTable inside a JScrollPane. This table has 14 cols. When the page is displayed, it displays only 8 cols. If I resize a column width, then the next cols is displayed. My code goes like this :
    <CODE>
    this.m_tableModel = new DefaultTableModel(data, headers);
    this.jTableDriversInfo = new JTable(this.m_tableModel);
    this.jTableDriversInfo.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
    this.jTableDriversInfo.getTableHeader().resizeAndRepaint();
    <CODE>
    Please help.

    If you turn AutoResize off then you have to manually set the size of your columns in order to get a correct look.

  • Jtable Header's border disappear  after placing an icon on it

    I tried this in java 1.4
    it works fine but the border between the headers of my JTable diappear
    Anyone knows why?
    ImageIcon icon = new ImageIcon(pathoficon);
    DefaultTableCellRenderer headerRenderer =new DefaultTableCellRenderer();
    headerRenderer.setIcon(pathoficon);
    TableColumnModel colmod = jtable.getColumnModel();
    colmod.getColumn(col).setHeaderRenderer(headerRenderer);
    jtable.getTableHeader().resizeAndRepaint();

    Its because DefaultTableCellRenderer isn't quite the mustard for a header renderer. Mine is shown below, the crucial line being setBorder(UIManager.getBorder("TableHeader.cellBorder"));
    private class SortHeaderRenderer extends    DefaultTableCellRenderer
        RenderInfo r_;
        SortHeaderRenderer(RenderInfo r)
          r_ = r;
      public Component getTableCellRendererComponent(javax.swing.JTable table,

          setHorizontalAlignment(SwingConstants.CENTER);
          setHorizontalTextPosition(SwingConstants.LEFT);
          // Check if we are the primary sort column and if so, which
          // direction the sort is in
          if ((orderItems_ != null) && (orderItems_.contains(r_)))
            if (sortDescending_)
              setIcon(sortDescending__.getIcon());
            else
              setIcon(sortAscending__.getIcon());
          else
            setIcon(null);
          return this;
    }Never mind about anything else because that's specific to me.

  • Refresh jTable after inserting new data into the Database

    Hey all,
    I'm using Netbeans 6.5 to create a Desktop Application which is connected to a Java DB (Derby).
    The first simple steps were all very successfull:
    Create the jTable and bind it to the Database => everything works fine. When the application starts it correctly shows all data from the database.
    The problem starts when I try to insert new data to the database.
    For that reason I've created textfields and a button "Save". When I press the button it successfully inserts the data to the database but they are not displayed in the jTable (when the application starts they are all there, they are not updated at runtime) . I've tried table.invalidate() and table.repaint() but they just don't work.
    Any help will be GREATLY appreciated. But please have in mind that most of the code is Netbeans-generated and most of it not editable.
    Many thanks in advance.
    George

    Once again you are right my friend. I jumped to conclusion way too fast, when I shouldn't. (Give me a break, I've been busting my head with this well over a week). The response I saw when I did that was that indeed a line is added to the jTable. Because I falsly set the index of the object to be added to be second to last the row appeared on the table, what I didn't see at the time was that the last one disappeared. Hmm...
    A new adventure begins...
    So after a few hours of messing around with it here are my observations:
    1) It was not an observable list. When I add the new element with employeesList.add(newEmp); , the table gets notified but a get a bunch of exceptions:

    ... and a lot morewhich from my poor understanding means that the jTable succesfully notices the change but it is not able (??) to adjust to the new change. What is more interesting is that when I plainly add the element to the end of the list (without an idex that is), a blank row appears at the end of my Table. The weird thing is that I've bound the table to some text fields below it, and when I select that empty row all the data appear correctly to the text fields.
    I tried going through:
                    org.jdesktop.observablecollections.ObservableCollections.observableList(employeesList).add(newEmp);as well as
                    help = org.jdesktop.observablecollections.ObservableCollections.observableListHelper(employeesList);
                    help.getObservableList().add(newEmp);
                    help.fireElementChanged(employeesList.lastIndexOf(newEmp));and
                    obsemployeesList = org.jdesktop.observablecollections.ObservableCollections.observableList(employeesList);
                    obsemployeesList.add(newEmp);and I still get the same results (both the exeptions and the mysterious empty row at the end of the table
    So, I'm again in terrible need of your advice. I can't thank you enough for the effort you put into this.
    Best regards,
    George

  • Problem printing the JTable

    Hi all,
    I have a problem with printing JTable.
    My application has a submit button,JTable and Print Button.
    As I click on the Submit button, the data is retrieved from the Database(MS Access) and displayed on the JTable.
    Now when I click on the Print button, the printer properties dialog box is displayed. But when I click on the print button in the dialog box, nothing is printed on the paper.
    I checked the printers and faxes in the control panel, It showed Java printing under the Document name and Printing under the Status. It is displayed for sometime and then disappeared after some time. But nothing is printed on the paper(not even the blank paper).
    I tried a lot but couldn't understand the problem.
    I have used the following files:

  • How to outline selected cells during drag and drop in the jtable

    Hi,
    I have spent a lot of time to find out how to outline selected cells during drag in the jtable, but I did not find the answer.
    Can anybody give me a tip, where to read more about this problem or even better, give an example...
    I have the following situation:
    1.Table has 10 rows and 10 columns
    2.setSelectionMode(ListSelectionModel.SINGLE_INTERVAL_SELECTION) and setCellSelectionEnabled(true)
    3.user select 5 cells in 4th row (for example cell45,cell46,cell47,cell48 and cell49)
    4.user starts dragging. During dragging an outline should be drawn. Outline should be a rectangular with width of 5 cells and height of one cell. Outline should move according to the mouse position.
    5.rectangular disappears when dropped
    Regards,
    Primoz

    In "createTransferable" you can create a drag image
    which you can paint in "dragOver" and clear in "drop" method of DropTarget :

  • Please help me..JTable trouble

    Hi all java guru,
    i've have a JTable in which i want to insert some styled text (e.g. bold,underline,italic).... i use a JEditorPane as CellEditor and JEditorPane as renderer. In each JEditorPane i have registered a StyledEditorKit that is used for styles.
    I've noted that when i insert styled text, initially cell maintains text style, but when i click on other cell,style of text disappears....i want to specify that i don't want to add style to entire cell, but i wish to add style at a portion of text.....
    notbold bold | not styled text
    Cell0 ----------------------- Cell1
    Is this behavior normally ???
    Then i've implemented a CustomTableModel that maintains information about text style, in such way that when renderer cell, i can rebuild exact text with its style....same method is adopted for CellEditor.
    It is possible to have more than one JTable in my application....then to correctly handle all JTables ' put the in a vector and during editing and rendering i find current focusable JTable and edit/render it.
    It seems a right solution ???
    I insert style on text using a toolbar and menubar in a dynamically way.
    Please, give to me an advice...Is right this solution??Or exist another way to resolve this proble in a more elegant way??
    Tnx in advance
    regards,
    anti-shock

    That's correct.
    Try to set HTMLEditorKit for your editor/renderer JTextPane. In the TableModel you can save text from textPane.getText() and set the text in the renderer component in the appropriate renderer's method.
    regards,
    Stas

  • Deleting a row from a JTable using a custom TableModel

    Before I waste any of your time I would like to go ahead and just say that I have searched through the forum using "delete row from Jtable" as the search keywords and while I have found very closely related issues, they have not solved my problem. I have found code postings by carmickr and his arguments as to why we should use DefaultTableModel instead of having created our own custom TableModel, and while I do agree, I just am not quite confident enough in applying it to my scenario. See I am reading from a file a bunch of Contractor objects and I am stuffing it into an arraylist which I am using in the following code posting to populate my TableModel which the JTable object in the gui then uses.
    My problem is that everything works except when I delete and when I delete I understand that the index is changing because I just removed a row from the arraylist object. Suppose I have 33 rows displaying in the GUI. Now after I delete say row #23, the delete function works and dutifuly the row disappears from the table, but if I try to delete a row say...the last row, it does not work and throws me an IndexOutOfBoundsException which totally makes sense. My question is how do I go about fixing it? Do I have to do something with the setRowCount method?
    Any help is appreciated.
    Cheers,
    Surya

    Wow that was a very quick response. Thanks camickr. I am only trying to delete a single row. I do not know how to go about posting a test program for the code I have posted above because honestly the gui itself is 800 lines of code, and then the file reading class is quite funky in itself. I can maybe email you the entire Netbeans project including code so if you are using Netbeans 5 RC2 you can run the code and see for yourself, but that would not be considerate of me.
    See I am trying to delete any row at any time...but only one at a time not multiple rows...so if a user decides to delete row 23 and then tries to delete the last row which happens to be row 33 in my case, my setup should be smart enough to still allow to delete the row.

  • JTable will not refresh with new data from database

    Hi,
    I have a JTable that does not recoginzed when the data has changed. The table is dynmaically populated with data from the database using a table model.
    Please help!!
    public JTable getUpdateContractTable() {
    QueryTableModel model;
    String [] dlrs = getSelectedDealers();
    String [] stats = getSelectedStatuses();
    String sql = buildContractQuery(dlrs, stats);
    try {
    if(isContractSet) {
    model = new QueryTableModel();
    model.setQuery(sql);
    table.setModel(model);
    table.setColumnModel(new UpdtCtrctColumnModel());
    table.invalidate();
    table.repaint();
    //model.fireTableChanged(new TableModelEvent(model));
    else {
    model = new QueryTableModel();
    UpdtCtrctColumnModel column = new UpdtCtrctColumnModel();
    model.setQuery(sql);
    table = new JTable(model, column);
    table.createDefaultColumnsFromModel();
    table.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
    table.setPreferredScrollableViewportSize(new Dimension(500, 70));
    model.fireTableChanged(null);
    isContractSet = true;
    catch (Exception e) {
    System.out.println(e.getMessage());
    //JOptionPane.show
    //.showMessageDialog("Error: " + e.getMessage(),
    // "Click Ok",
    // JOptionPane.INFORMATION_MESSAGE);
    return table;
    }

    thank you for your help. i finally got it to refresh. i have a follow-up question if you don't mind answering it. i have 2 jtables where one depends on the other. when i do a refresh i want the other table to disappear, so i call the getContentPane().remove(component), but the table doesn't disappear. what should i do.

  • 2 JScrollPanes and 1 JTable

    I have searched for about an hour and I can't find anything related to this. I apologize in advance if this is a repeat post.
    I have a JTable that is being displayed in a JScrollPane that is nestled into a JFrame. I am attempting to build another Scroll Pane with the same table in it, using the following code.:
    JScrollPane scrollPane = new JScrollPane(this.table);
    int width = this.table.getPreferredSize().width + 5;
    int height = this.table.getPreferredSize().height + 5 +
                         this.table.getTableHeader().getHeight();
    Dimension ps = new Dimension( width, height );
    scrollPane.setPreferredSize(ps);
    JWindow window = new JWindow();
    window.setSize(ps);
    window.getContentPane().add(scrollPane);
    window.pack();
    window.show();The new window displays fine and the table shows up, but the original table disappears as soon as the JFrame it is in redraws?! Can anybody provide an explanation of why this is happening and hopefully how to fix it?

    A Swing component can only belong to one container. Thanks, that was the small but very important piece of information I didn't know. I already had implemented something similar to what you suggested, but it was a little more complicated due to the nature of the table. I was hoping to get away with being lazy. Oh well...
