JTable Header corrupted

I'm having a problem with the JTable headers, in that I am trying to use
a function that sets the initial column sizes for each of the columns,
using a AbstractTableModel derivative. But the headers, once rendered,
after column 10, seem to have the first row data in them. It literally
looks like the first row is duplicated over top of the headers, since
both are visible if not completely legible.
IF I take out the function and the call to it that sets the initial
column sizes, it works perfectly, but as most of you know, the size
defaults to about 12-15 width, which barely, if at all, shows the first
character of the header.

  • How do i change the cursor on a jtable header when clicked for sorting?

    here is my question, how do i change the cursor on a jtable header when I click the header for sorting?
    I think it is suppose to be in the fragment of code where the header listener is implemented for sorting, but I'm not quite sure what is the exact component that holds everything so that i can change the cursor...
    below is what I've tried, but it doesn't seem to work... thank you
    public void addMouseListenerToHeaderInTable(JTable table) {
    final TableSorter sorter = this;
    final JTable tableView = table;
    tableView.setColumnSelectionAllowed(false);

    Try setting the cursor for the table header.
    table.getHeader().setCursor(Wait_Cursor);

  • How to add  ComboBox in Jtable Header

    Hello everyone,
    I want to add a Combox box in JTable Header .Basically it works as central access to whole table e.g. by selecting delete row in combo box then it should delete the current selected row.If somebody has any idea please share it.
    Thanks in advance.

    The individual headers are not Swing components and therefore do not respond to mouse events in the same way as Swing components. Why don't you just have a popup menu that is positioned over the currently selected row? If you want to apply an action to all selected rows then have a set of buttons placed above the table header.

  • JComboBox in the JTable Header - TableCellEditor problem

    Hi,
    I have added JComboBox into the JTableHeader. But I can't Edit that combobox. It is looking like an icon. I have added JPanel into the JTable Header Row. In JPanel i have added one JLable and JComboBox.
    Please any one of you give me the solution.
    Thanks,
    Shrini V.

    The table will display what ever value it has in its model. When you add the row, there is no data in the second column. You'll have to supply it.
    public void insertMyRowCombo (Object [] r,
                                      JComboBox c,
                                      JTable t) {
           // {"rut", "puntaje cas", "beneficio", "fecha inicio", "fecha termino", "monto"};
            DefaultTableModel tm = (DefaultTableModel) t.getModel();
            tm.addRow(r);
            TableColumn col = t.getColumnModel().getColumn(2);
            col.setCellEditor(new DefaultCellEditor(c));
            tm.setValueAt( c.getItemAt(0), 0, 2); //manually supply the value to col 2
        }ICE

  • Multiple Icon on Jtable header

    Hi All:
    Any one had used multiple icons on JTable header ? According to the user's clicking positon under one column, one of these icons should change such as changing from sorting up arrows to sorting down arrows.
    I got the mouse clicking position on the header and column, then depend on the location, I wanted to perfrom different things. But I have not figured out if I should call header renderer to perform the repaint or not ? If I use JTable header render, how should I confine the one column that change should happen? I don't want to have all columns repainted. If I treat each column indivisually, should I reconstruct the JTable ? I used SortableTableModel to create the JTable.
    Any help is appreciated.
    Regards

    Here's the idea. I didn't test thisclass JComponentCellRenderer extends JButton implements TableCellRenderer {
        public JComponentCellRenderer (ImageIcon ii) { super("",ii); }
        public Component getTableCellRendererComponent(JTable table, Object value,
            boolean isSelected, boolean hasFocus, int row, int column) {
            setText(value.toString());
            return this;
    }and thentblChanges.getColumnModel().getColumn(0).setHeaderRenderer(new JComponentCellRenderer(new ImageIcon( "CheckBoxHeaderImage" )));

  • How to set height of JTable Header ?

    How to set height of JTable Header and set the text to another size ?

    You can set the font of the header as you can for any component. The font will dictate the preferred height of the header. If you don't like the preferred height, you can set that as well.
    // add table to a scroll pane or the header will not appear
    JTable table = new JTable(...);
    container.add(new JScrollPane(table));
    // get a reference to the header, set the font
    JTableHeader header = table.getTableHeader();
    header.setFont(new Font(...));
    // set the preferred height of the header to 50 pixels.
    // the width is ignored by the scroll pane.
    header.setPreferredSize(new Dimension(1, 50));Mitch Goldstein

  • Changing jtable header when moving down

    Hi,
    I would need changing Jtable header, when the cursor switches between lines
    How to do this ???
    Best Regards
    S.Ancelot

    1) You could create a second table header and replace the old one using scrollPane.setColumnHeaderView(...)
    2) Or, you could simply change the values in each TableColumn and then repaint the header.

  • How to remove JTable header from JScrollPane?

    Hi!
    Does anyone know how to remove the JTable header from the JScrollPane the table is placed in? I tried calling
    scrollpane.setColumnHeader( null ) and
    scrollpane.setColumnHeaderView( null )
    but none of the above worked...
    Thanks!
    Fil

    Hi,
    The easiest way to do this is to put an extra layer between the table and the scrollpane as follows:-
    JPanel p = new JPanel(new BorderLayout());
    // Add it to the north rather than center so that the table background color
    // won't cover the empty part of the view port.
    p.add(table, BorderLayout.NORTH);
    JViewport v = tableScroll.getViewport();
    v.setView(p);
    where table is your JTable and tableScroll is your JScrollPane.
    Hope this helps,
    Ian
