JTable with JToolBar inegrated

Hello.
My requirement: A swing component (JPanel, JTable...) consisting of a table and a tool bar with buttons for inserting/removing rows in the table. This component must be visually configurable in NetBeans vía 'Table contents...' dialog.
If I extend JPanel I won't be able to visually edit the table inside; if I extend JTable I don't know how to integrate the toolbar inside of it.
Any hint?
Thank you.
Antonio.

Solution:
1. Extend JPanel, e.g. JTablePanel, with BorderLayout, and add a tool bar (north) and a container (center) where the table will be placed, e.g., private JPanel tablePanel;.
2. Create a public method that returns that container where the table will be placed, e.g.: public JPanel getTablePanel();3. Create a BeanInfo for your table panel: JTablePanelBeanInfo. You can return the defaults for all of the methods but getBeanDescriptor should look like this:
    @Override
    public BeanDescriptor getBeanDescriptor() {
        BeanDescriptor beanDescriptor = new BeanDescriptor(com.yourpackage.JTablePanel.class, null );
        beanDescriptor.setValue("containerDelegate", "getTablePanel");
        return beanDescriptor;
    }The point here is setting the value "containerDelegate".
4. Compile everything and create a new BeanForm based on JTablePanel and put your table instance inside the form by dragging it from the palette.
5. Now you can visually customize your table, improving reusability and productivity in your project.

  • JTable with JCheckbox problems

    Ok so I have a couple of questions. I have a JTable with a column represented as a checkbox.
    1. If I put the checkbox column as the first in the table, the rest of the cells are blank/null. Any idea what the reason is?
    2. What is the best workaround to having draggable columns, meaning icons/checkboxes don't render if you move the columns around?
    3. Does anyone have some links to good resources on JTables and things like custom components in them. I have googled but don't get many good links so would appreciate any help
    Code snippet as follows:
    public class ClobberTableCellRenderer implements TableCellRenderer
    private JPanel renderPanel = new JPanel(new BorderLayout());
    private JLabel renderLbl = new JLabel("");
    private JCheckBox checked = new JCheckBox();
    private Icon successIcon;
    private Icon errorIcon;
    public Component getTableCellRendererComponent(JTable table,
    Object value,
    boolean isSelected,
    boolean hasFocus,
    int row,
    int column)
    String columnName = table.getModel().getColumnName(column);
    if (value == null)
    return null;
    else if ("Status".equals(columnName) && "ok".equals(value))
    renderLbl.setIcon(successIcon);
    renderLbl.setText("");
    renderPanel.remove(checked);
    else if ("Status".equals(columnName) && "error".equals(value))
    renderLbl.setIcon(errorIcon);
    renderLbl.setText("");
    renderPanel.remove(checked);
    else if ("Active".equals(columnName))
    renderLbl.setText("");
    renderPanel.add(checked);
    renderPanel.setBackground(Color.white);
    else
    renderLbl.setHorizontalAlignment(value instanceof Date || value instanceof Number ? JLabel.RIGHT : JLabel.LEFT);
    renderLbl.setIcon(null);
    renderLbl.setText(value instanceof Date ? df.format((Date)value) : value.toString());
    renderLbl.setToolTipText(null);
    renderPanel.setToolTipText(null);
    renderPanel.remove(checked);
    if (isSelected)
    renderPanel.setBackground((Color)UIManager.getDefaults().get("Table.selectionBackground"));
    else
    renderPanel.setBackground((Color)UIManager.getDefaults().get("Table.background"));
    return renderPanel;
    }

    Hi :) I have also worked on JTables and JCheckBoxes before. This article

  • JTable with JComboBox/JSpinner problem

    The following code has a JTable with 2 columns.The lst column has JComboBoxes, the 2nd column has JSpinners.I want to set the spinner range of values based on the selection of JComboBox. The JComboBox selections are "small" and "large". For "small" the spinner should range from 0..49, for "large" from 50..99. When a selection is made, MyTable.itemStateChanged() is called, which in turn calls SpinnerEditor.setValueRange(). This sets an array with the desired values and then sets the model with this array. However, it sets the range not only for the row in which the combo box was clicked, but all rows.
    So in MyTable.setCellComponents(), there is this:
    spinnerEditor = new SpinnerEditor(this, defaultTableModel);
    modelColumn.setCellEditor(spinnerEditor);
    If the table has n rows, are n SpinnerEditors created, or just 1?
    If 1, do n need to be created and if so, how?

    However, it sets the range not only for the row in which the combo box was clicked, but all rows. Yes, because a single editor is used by the column.
    One solution is to create two editors, then you override the getCellEditor(...) method to return the appropriated editor. Something like:
    If (column == ?)
        if (smallOrLarge)
          return the small or large spinner editor
        else
           return the large spinner editor
    else
        return super.getCellEditor(...);

    - it's not the JTable's business to compute its headers size (and it doesn't, the header's the culprit.) *> - the header should never come up with a zero (or near-to) height: even if there is no title shown, it's still needed as grab to resize/move the columns. So I would consider this sizing behaviour a bug.*
    - furthermore, the "really zero" height is a longstanding issue with MetalBorder.TableHeaderBorder (other LAFs size with the top/bottom of their default header cell border) which extends AbstractBorder incorrectly. That's easy to do because AbstractBorder itself is badly implemented

  • Need help serializing an AbstractTableModel for a JTable with cell editing.

    Fun times are ahead. Here we go!
    I have a JTable that contains data I'd like to serialize out to a file to be restored and viewed later.
    So I tried saving the AbstractTableModel subclass out to a file. Whenever I do this, I get the following error message:
    java.io.NotSerializableException: javax.swing.JTable$CellEditorRemover
    Now I know for fact that serializing an AbstractTableModel that was installed in a JTable without cell editing works just fine (my old code did exactly that). As a result, I think that the code that handles events in the AbstractTableModel contains references back out to the JTable, which causes the JTable to be saved no matter what (even though I'm just interested in saving the TableModel only). It causes a bigger file than normal, but file size is not an issue. The only issue I have is that CellEditorRemover (an undocumented inner class of JTable), which is automatically installed for JTables with editable cells, is not serializable.
    This leads to the following questions:
    1. Is there a way to avoid serialization/deserialization of the CellEditorRemover inner class of JTable?
    2. Is there a way to save an AbstractTableModel without saving all of the event listeners associated with it?
    I think an answer to either of these questions would go a long way towards solving my problem. Otherwise, I'll resign myself to weeping silently in the corner of my office.
    Thanks!

    I would suggest that if you can you only save the
    data... but i would do this by using the
    externalizable interface.
    What you will need to do is have the
    writeExternal(ObjectOutputStream out) and
    readExternal(ObjectOutputStream out) methods in your
    class. These will be responsiable for saving the
    data.
    Here's an example of what you can do in these
    methods... this is just a little tidbit from a program
    i've written.public void writeExternal(ObjectOutput out) throws
    IOException {
              out.writeInt(size);
              out.writeObject(drawName);
              out.writeInt(playersLength);
    for(int i = 0; i < playersLength; i++)
    ) out.writeObject(players);
              out.writeInt(seedsLength);
    for(int i = 0; i < seedsLength; i++)
    ) out.writeObject(seeds[i]);
              out.writeInt(drawLength);
    for(int i = 0; i < drawLength; i++)
    ) out.writeObject(draw[i]);
    public void readExternal(ObjectInput in) throws
    IOException, ClassNotFoundException {
              size = in.readInt();
              drawName = (String)in.readObject();
              playersLength = in.readInt();
    for(int i = 0; i < playersLength; i++) players[i] =
    = (String)in.readObject();
              seedsLength = in.readInt();
    for(int i = 0; i < seedsLength; i++) seeds[i] =
    = (String)in.readObject();
              drawLength = in.readInt();
    for(int i = 0; i < drawLength; i++) draw[i] =
    = (String)in.readObject();
    You can now use your class as you would a Serializable
    class, but it will only save the data
    Hope this helped

    I forgot to add some critical information in my original post. My apologies. :(
    I've thought about using Externalizable, but am hesitant to use it because the application would no longer be able to read in files using the old save format (ie, AbstractTableModels for JTables without CellEditorRemovers ).  I want to preserve the ability to read the old saved AbstractTableModel formats if possible. 
    Do you know of a way to revert to the default deserialization mechanism from readExternal?  This way, during deserialization, I could do a quick test on the object being read and have the ability to default to the regular deserialization mechanism if the object is of the old type or continue with the new Externalizable stuff if the object is one of the new type.  Maintaining file compatibility is key.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                       

  • Can we create JTable with multiple rows with varying number of columns ?

    Hi All,
    I came across a very typical problem related to JTable. My requirement is that cells should be added dynamically to the JTable. I create a JTable with initial size of 1,7 (row, columns) size. Once the 7 columns are filled with data, a new row should be created. But the requirement is, the new row i.e. second row should have only one cell in it initially. The number of cells should increase dynamically as the data is entered. The table is automatically taking the size of its previous row when new row is added. I tried by using setColumnCount() to change the number of columns to '1' for the second row but the same is getting applied to the first row also.
    So can you please help me out in this regard ? Is it possible to create a JTable of uneven size i.e. multiple rows with varying number of columns in each row ?
    Thanks in Advance.

    Well a JTable is always going to paint the same number of columns for each row. Anything is possible if you want to rewrite the JTable UI to do this, but I wouldn't recommend it. (I certainly don't know how to do it).
    A simpler solution might be to override the isCellEditable(...) method of JTable and prevent editing of column 2 until data in column 1 has been entered etc., etc. You may also want to provide a custom renderer that renderers the empty column differently, maybe with a grey color instead of a white color.

  • Mouse motion listener for JTable with JScrollpane

    Hi All,
    I have added mouse motion listener for JTable which is added in JScrollPane. But if i move the mouse, over the vertical/horizontal scroll bars, mouse motion listener doesn't works.
    So it it required to add mousemotionlistener for JTable, JScrollPane, JScrollBar and etc.
    Thanks in advance.
    Regards,
    Tamizhan

    I am having one popup window which shows address information. This window contains JTable with JScrollPane and JButton components to show the details. While showing this information window, if the mouse cursor is over popupwindow, it should show the window otherwise it should hide the window after 30 seconds.
    To achieve this, i have added mouse listener to JPanel, JTable, JButton and JScrollPane. so if the cursor is in any one of the component, it will not hide the window.
    but for this i need to add listener to all the components in the JPanel. For JScrollPane i have to add horizontal, vertical and all the top corner buttons of Scroll bar.
    Is this the only way to do this?

    hi again,
    To print pdf in a swing application you don't need servlet.jar.
    You'll only need itext.jar and a printer connected to your pc.
    Download the iText source code and unzip it. See the following classes:
    com.lowagie.tools.LPR and com.lowagie.tools.BuildTutorial. This latter is the main class of a swing tool that you can run.
    Silent Print:
    You have only to embed this javascript code in your pdf:
    writer.addJavaScript("this.print(false);", false);
                        document.add(new Chunk("Silent Auto Print"));Then, you have to send the document to the printer.
    Google : java print pdf
    http://forum.java.sun.com/thread.jspa?threadID=523898 or
    http://www.exampledepot.com/egs/javax.print/pkg.html for printing task.
    Under unix system, I used this:
                           String PRINTER = ...;
                   try {
                        String cmd = "lp -d " + PRINTER + " " + PDF_PATH;
                        Runtime.getRuntime().exec(new String[] { "sh", "-c", cmd });
                   } catch (Exception e) {
                                 //handle the exception
                                 e.printStackTrace();
                   }hth

  • Print Jtable with multiline header?

    i want to print jtable with multi-lines header and footer
    using the print function that takes MessageFormat as header and footer
    i used MessageFormat header = new MessageFormat("hello\r\nworld");and i used '\n' only
    but it was printed all in the same line
    thnx in advance

    You can try something on the below lines. Set your custom renderer for the tableheader.
    public class MultiLineHeaderRenderer extends DefaultTableCellRenderer{
            public Component getTableCellRendererComponent(JTable table, Object value,
                             boolean isSelected, boolean hasFocus, int row, int column) {
                         JLabel label = (JLabel) super.getTableCellRendererComponent( table,  value,
                              isSelected,  hasFocus,  row,  column);
                        label.setText("<html>a<br>b</html>");
                        return label;
        }Not the best way to do it. And might need to some modifications too to set the font position etc.

    I have two Icons display on 2 JButtons (2 different ToolTipText for buttons). The Buttons are display on a JPanel. The Panel is display on one of the cell inside JTable. Is it possible that when I move the mouse over each Icon it will displays the ToolTipText of each of the JButton (I am try to replace the ToolTipText of the JTable with the ToolTipText of the JButton when mouse over and when I move the mouse to the next JButton I get a different ToolTipText). The reason I am using the JButton is that in the future I will add actionListener() to do something when the user click on it.
    I have try working with glassPane, addMouseMotionListener, MouseEvent.getPoint(), SwingUtilities.convertPoint, SwingUtilities.getDeepestComponentAt.
    Thank you in advance.
    Note: I am getting the Icons from Object [].

    Hello, the following is one ugly piece of code but I guess that's pretty much what you were after. Just test the tooltip and you'll see that it depends both on the cell and on which of the two buttons is hovered.import javax.swing.*;
    import javax.swing.table.TableCellRenderer;
    import java.awt.*;
    import java.awt.event.MouseEvent;
    public class TestTooltipTable {
         private static class CustomTableCellRenderer implements TableCellRenderer {
              private JButton theLeftButton;
              private JButton theRightButton;
              private JPanel thePanel;
              public CustomTableCellRenderer() {
                   theLeftButton = new JButton("left action");
                   theRightButton = new JButton("right action");
                   thePanel = new JPanel(new GridLayout(1, 2)) {
                        public String getToolTipText(MouseEvent e) {
                             Point p = e.getPoint();
                             Rectangle leftRect = theLeftButton.getBounds();
                             Rectangle rightRect = theRightButton.getBounds();
                             if (leftRect.contains(p)) {
                                  return theLeftButton.getToolTipText();
                             } else if (rightRect.contains(p)) {
                                  return theRightButton.getToolTipText();
                             return " ";
                   thePanel.add(theLeftButton);
                   thePanel.add(theRightButton);
              public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected,
                                                                        boolean hasFocus, int row, int column) {
                   String text = (String)value;
                   theLeftButton.setToolTipText("left action " + text);
                   theRightButton.setToolTipText("right action " + text);
                   return thePanel;
         public static void main(String[] args) {
              final JFrame frame = new JFrame(TestTooltipTable.class.getName());
              frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
              Object[][] data = {{"1", "A"}, {"2", "B"}, {"3", "C"}};
              String[] columnNames = {"Number", "Letter"};
              JTable table = new JTable(data, columnNames) {
                   public String getToolTipText(MouseEvent event) {
                        return super.getToolTipText(event);
              table.setDefaultRenderer(Object.class, new CustomTableCellRenderer());
              ToolTipManager.sharedInstance().registerComponent(table);
              frame.getContentPane().add(new JScrollPane(table));
              SwingUtilities.invokeLater(new Runnable() {
                   public void run() {
                        frame.pack();
                        frame.show();
    }

  • How can I print a JTable with varying sized rows?

    How can I print a JTable with varying sized rows?
    I am using java 1.5, and have made a cell renderer to display multiple lines in rows and it works well, however when I use the new print method it doesn't separate the cells onto the next page, it cuts them and will print the rest of the row on the next page. Does anyone know how I might go about making this happen?
    cheers

    I finally found out the reason, The column heights were being set through my renderer. If I hadn't viewed them in the scrollpane the row heights were set to the default height of 16 therefore when the print method was called it clipped all the rows wrong, what is weird though is that the row height printed out correctly but the clipping area was set wrong because it was getting the default value of 16 from rowHeight(row).

  • JTable with custom combobox

    Hi
    I been trying to create a JTable with a custom combobox, that is in a column the lists contained within each combobox is unique. I tried using a renderer, even though the combo appears I cannot select the combo for editing. Any suggestions on how to get the combo working properly would be appreciated thanks.

    It's been a few years since I did something like this, but my recollection is that you should implement the TableCellEditor interface and have the getTableCellEditor method return your custom combo box. Then, either override getCellEditor in your JTable to return your custom TableCellEditor or (better) call tableColumn.setCellEditor for the column you're interested in, passing an instance of your TableCellEditor. I suggest you return the same JComboBox from your implementation of getTableCellEditor every time, and either replace the underlying model or have a custom model in which you can easily switch the contents on-the-fly.
    Having done this in the past, I remember that it's quite easy to leak stuff - I wouldn't advise making a new JComboBox every time.

  • JTable with AUTO_RESIZE_OFF not resizing at all!

    I tried to find solution in other posts, but no success.
    I created a JTable with
    table.setAutoResizeMode(javax.swing.JTable.AUTO_RESIZE_OFF);That�s fine, but now I can�t resize it at all while interacting with it.
    That�s the main code of the table.
    I�d appreciate any any help.
    Thanks in advice.
            int preferredWidth = 0;
            int preferredSizeSum = 0;
            //Rebuild TableColumnModel with correct number of columns
            ((AbstractTableModel)getTable().getModel()).fireTableStructureChanged();
            //Set the columns widths based on the field data
            TableColumnModel columnModel = getTable().getColumnModel();
            for (int i = 0; i <= multiProperties.size(); i++) {                       
                TableColumn column = columnModel.getColumn(i);
                //Start with the reported column width
                preferredWidth = column.getWidth();
                //Enforce minimum width needed to display column header text
                preferredWidth = Math.max(preferredWidth, ((AbstractTableModel)getTable().getModel()).getColumnName(i).length() * 10);
                //Enforce maximum width so long fields get truncated
                preferredWidth = Math.min(preferredWidth, 200);
                //Set the column width
                column.setPreferredWidth( preferredWidth );
                column.setMinWidth( 5 );
                column.setMaxWidth( 500 );
                preferredSizeSum += preferredWidth;
            getTable().setMaximumSize( new Dimension( 500*multiProperties.size(), tableHeight ) );
            getTable().setMinimumSize( new Dimension( 5*multiProperties.size(), tableHeight ) );
            getTable().setPreferredSize( new Dimension( preferredSizeSum, tableHeight ) );       
            getTable().setSize( new Dimension( preferredSizeSum, tableHeight ) );

    Works fine for me:

    If you need further help then you need to create a [url http://homepage1.nifty.com/algafield/sscce.html]Short, Self Contained, Compilable and Executable, Example Program (SSCCE) that demonstrates the incorrect behaviour, because I can't guess exactly what you are doing based on the information provided.
    And don't forget to use the [url http://forum.java.sun.com/help.jspa?sec=formatting]Code Formatting Tags so the code retains its original formatting.
