Question

I’m doing a project but I have a little problem with a Frame, I have a problem with a table.

Well, I have this:

The source that have for the previous picture is:

public class Geotools04 extends JFrame {
private JMapFrame mapFrame;
static StyleFactory styleFactory = CommonFactoryFinder.getStyleFactory(null);
static FilterFactory filterFactory = CommonFactoryFinder.getFilterFactory(null);

Geotools04(File[] files) throws IOException, CQLException {


        FileDataStore store = FileDataStoreFinder.getDataStore(files[0]);
        SimpleFeatureSource featureSource = store.getFeatureSource();

        Filter filter = CQL.toFilter("MAN_COD = '01'");
        SimpleFeatureCollection features = featureSource.getFeatures(filter);
        FeatureCollectionTableModel model = new FeatureCollectionTableModel(features);


        for(int i=0;i<model.getColumnCount();i++){
            System.out.println(model.getColumnName(i));
        }

        JFrame frame = new JFrame();


        JTable table = new JTable();

        frame.setLayout(new GridLayout(6, 2)) ;

        JLabel a = new JLabel("Capas existentes:");

        JComboBox layer = new JComboBox();
        for(int i=0; i < files.length ; i++){
            layer.addItem(files[i].getName());    
        }

        JLabel c = new JLabel("Atributos de capa:");

        JComboBox d = new JComboBox();
        d.addItem ("MAN_COD");

        JCheckBox e = new JCheckBox("Where");
        JTextField f = new JTextField("= '01'");
        JCheckBox g = new JCheckBox("Where igual");

        JTextField h = new JTextField("01");
        h.setEditable(false);

        JCheckBox i = new JCheckBox("Todos los registros");
        JButton j = new JButton("Consultar");

        frame.add(a);
        frame.add(layer);
        frame.add(c);
        frame.add(d);
        frame.add(e);
        frame.add(f);
        frame.add(g);
        frame.add(h);
        frame.add(i);
        frame.add(j);

        table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
        table.setModel(new DefaultTableModel(5, 5));
        table.setPreferredScrollableViewportSize(new Dimension(500, 200));
        JScrollPane scrollPane = new JScrollPane(table);
        table.setModel(model);
        frame.add(scrollPane);

        frame.setSize(600, 600);
        frame.setVisible(true);
}
}

But I need that my frame look like this:

So, can you help me, I put all in a GridLayout but I need that the last table
be bigger… But I don’t know how to organize the element for put in the way that
I want to…

Try like this:

1. Instead of adding components directly on JFrame create separate JPanel and add all components except JScrollPane (which contains JTable) and “Salir” button.

2. Set BorderLayout for your JFrame.

3. Set GridLayout for that JPanel add components and add that JPanel to NORTH of JFrame.

   frame.add(panel, BorderLayout.NORTH);
   

4. Add JScrollPane to CENTER of your JFrame

   frame.add(scrollPane, BorderLayout.CENTER);
   

5. You can add your “Salir” button directly to SOUTH of frame or you can create one more JPanel add “Salir” button to that JPanel and finally add JPanel to SOUTH of frame:

   frame.add(salir, BorderLayout.SOUTH);
   

   or

   JPanel salirPanel = new JPanel();
   salirPanel.setLayout(new FlowLayout(FlowLayout.RIGHT,3,3));
   salirPanel.add(salirButton);
   frame.add(salirPanel);
   

P.S. Don’t forget to call frame.pack(); instead of frame.setSize(); before calling frame.setVisible(); method!

EDIT

Consider using some other layout for your upper components, like GridBagLayout
or MiG Layout instead of GridLayout.
