Java table formatting

I’im programing in Java with Netbeans.

I have a table who list patients. I read the information in XML file. Here you have the code:

package digiscope;

import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import java.io.File;

/**

 * @author Daniel
 */
public class TabelaPaciente extends javax.swing.JPanel {


 String numero_processo;
    int localizador = 0;

    /** Creates new form TabelaPaciente */

    public TabelaPaciente() {
        initComponents();
        load_table();
    }

    public void setNumeroProc(String numero) {
        numero_processo = numero;
    }

    public String getNumeroProc() {
        return numero_processo;
    }

    public int getLocalizador() {
        return localizador;
    }

    String[][] concat(String[][] A, String[][] B) {
        String[][] C = new String[A.length + B.length][A.length + B.length];
        System.arraycopy(A, 0, C, 0, A.length);
        System.arraycopy(B, 0, C, A.length, B.length);

        return C;
    }

    private void load_table() {

        File dir;
        String[] filenames;

        //dir = new File(System.getProperty("user.dir")+ "/XML");
        dir = new File(System.getProperty("user.dir") + "/Processos");

        filenames = dir.list();

        String[][] table_final = new String[][]{};

        for (int i = 0; i < filenames.length; i++) {

            String n_proc = filenames[i];//filenames[i].substring(0,filenames[i].length()-4);

            //System.out.println(filenames[i]);

            Ler_XML xml = new Ler_XML(n_proc);
            String nome_utente = xml.getNome();

            String[][] line = new String[][]{
                {n_proc, nome_utente, null, "ir para formulario"}
            };

            table_final = concat(table_final, line);
        }

        tabela_pacientes.setModel(new javax.swing.table.DefaultTableModel(
                table_final,
                new String[]{
                    "Process Nº", "Name", "Date", "Form state"
                }));
    }



    void executa_accao(int column, int row) {

        if (column == 3) {
            Object numero_proc = tabela_pacientes.getValueAt(row, 0);

            localizador = 1;

            numero_processo = numero_proc.toString();

            JanelaPrincipal cont = (JanelaPrincipal) this.getParent() //    Internal Pane
                    .getParent() // ???
                    .getParent() // ???
                    .getParent() // ???
                    .getParent();   //  Frame

            cont.loadPanel(new Formulario(1));

            Preencher_FormPaciente new_xml = new Preencher_FormPaciente(numero_processo, 1);

        }

    }

I would like to know if it’s possible to increase the letter size? You can see here a preview of the table.

Thank you for your collaborati开发者_运维百科on.

Best regards.

In many cases a table will use multiple renderers to render the data. One for Strings, Numbers, Dates etc. The default renderers use the Font of the table to render the text. To change the font for all renderers you can use:

Font font = table.getFont();
table.setFont( font.deriveFont(24.0f) );
table.setRowHeight(24);

You can do this for the table header as well.

The display of a cell in a JTable is controlled by the TableCellRenderer. The default implementation extends from JLabel which has methods to control font. For example...

DefaultTableCellRenderer newRenderer = new DefaultTableCellRenderer();
Font oldFont = newRenderer.getFont();
Font bigFont = new Font(oldFont.getName(),oldFont.getStyle(),24);
newRenderer.setFont(bigFont);
table.setDefaultRenderer(Object.class,newRenderer);
