Problems with JTable & JComboBox

[Andreas Rutvik]

Hi all.

I'm having a small problem with my GUI. I have my JTable with all the flights available. When I click on a row in the JTable another JTable appears together with a JComboBox (for choosing how many seats the user wants to book ) next to the "Book" button. The problems I have are 2 :

1. I can't see the column names for this 2:nd JTable
2. I can't see the available seats option in my JComboBox.

Here is how the GUI looks like when a row is selected in main JTable



Here is my code (important pieces ):

  
 
mainTable = new JTable ( this.tableModel );
 
mainTable.addMouseListener ( new MouseAdapter ( )
                {
                    public void mouseClicked ( MouseEvent e )
                    {
                        int row = mainTable.getSelectedRow ( );
                        int column = mainTable.getColumnCount ( );
                        String [][]values = new String[1][column];
                        String [ ] header = {
                                "ABQ", "ATL", "BOM", "DAL", "DEN", "FRA", "LAX", "SFO"
                        };
                        String [ ] seats = {
                                "1", "2", "3", "4", "5", "6", "7", "8"
                        };
                        for ( int i = 0; i < column; i++ )
                        {
                            values[0][i] = (String)tableModel.getValueAt(row,i);                    
                        }
                        selectedFlightTable.setModel(new FlightsTableModel(values,header));
                        seatsForSelectedFlight.setSelectedItem(seats);
                        seatsForSelectedFlight.setVisible(true);
                    }
                } );
 

// create the bookPanel
        JPanel bookPanel = new JPanel ( new FlowLayout ( FlowLayout.CENTER ) );
        selectedFlightTable = new JTable ( );
        seatsForSelectedFlight = new JComboBox();
        seatsForSelectedFlight.setVisible(false);
        JButton bookButton = new JButton ( "Book" );
        bookButton
                .setToolTipText ( "Please click on the button to book the selected flight" );
        bookPanel.add ( selectedFlightTable );
        bookPanel.add ( seatsForSelectedFlight );
        bookPanel.add ( bookButton );
        viewSearchBookPanel.add ( bookPanel, BorderLayout.SOUTH );
 
        outerPanel.add ( viewSearchBookPanel, BorderLayout.NORTH );
        // Add the scroll pane to this panel.
 
        add ( outerPanel, BorderLayout.CENTER );

Of course, don't care about the fact that I've hardcoded some code etc. etc. This is just for testing purposes :=)

Best regards

Ps. Maybe it's easier to help if a paste in all code for my GUI ? It's just feels as it is a bit to much Ds.

The problem was that the 2:nd JTable was NOT embedded in a JScrollPane and therefore automatically the JTableHeader is not visible. I solved this easily by adding the following lines :

 
// create the bookPanel
        JPanel bookPanel = new JPanel ( new FlowLayout ( FlowLayout.CENTER ) );
        selectedFlightTable = new JTable ( );
        selectedFlightTable.getTableHeader().setReorderingAllowed(false);
        selectedFlightTable
                .setPreferredScrollableViewportSize ( new Dimension(600,20 ));
        //        {
        //            // Override this method so that it returns the preferred
        //            // size of the JTable instead of the default fixed size
        //            public Dimension getPreferredScrollableViewportSize() {
        //                return getPreferredSize();
        //            }
        //        };
 
        JScrollPane selectedFlightPane = new JScrollPane ( selectedFlightTable );
        seatsForSelectedFlight = new JComboBox ( );
        seatsForSelectedFlight.setVisible ( false );
        bookButton = new JButton ( "Book" );
        bookButton
                .setToolTipText ( "Please click on the button to book the selected flight" );
        bookButton.setEnabled ( false );
        //bookPanel.add ( selectedFlightTable );
        bookPanel.add ( selectedFlightPane );
        bookPanel.add ( seatsForSelectedFlight );
        bookPanel.add ( bookButton );
        viewSearchBookPanel.add ( bookPanel, BorderLayout.SOUTH );
