[Java]{Lama dotaz}Nacitani matice v GUI

Cau muzete mi nekdo prosim poradit jak na nacitani matice v Jave, pri pouziti grafickeho rozhrani(trida awt)?
Zkousel jsem uz spoustu veci, tohle je moje posledni verze, ale porad to nejede(melo by to fungovat tak ze kazde zadavane cislo napisu do TextFieldu t, potvrdim ho tlacitkem a ono se ulozi do matice, ale nebranim se ani jinym navrhum reseni)

Tohle je ta nacitaci trida:

Kód:

class Nacti implements ActionListener { private int cislo; private TextField t; public Nacti(TextField t, int cislo) { this.cislo = cislo; this.t = t; } public void actionPerformed(ActionEvent e) { // try { int k = 0; for (int i = 0; i < pom.length; i++) { for (int j = 0; j < pom[i].length; j++) { System.out.println("Zadejte prvek matice: "); t.select(k,k+1); pom[i][j] = Int.parseInt(t.getSelectedText()); System.out.println(t.getSelectedText()); k++; } } show(pom);}

Toho System.out... si nevsimejte, to jeste predelam, ted musim vyresit aby fungovalo to nacitani, show je metoda pro vypis te matice, pom je dvourozmerne pole, jak uz jste si jiste vsimli :wink:
Diky vsem za rady

Nic ve zlem, ale to cos vytvoril mi pripada dost zmatene. Ve zpracovani udalosti v tom cyklu nacitat matici nemuzes - ta udalost se vztahuje k zadani jedine hodnoty. Potom bys jeste musel nejak resit, ktery je to radek a sloupec.

Zkus tohle - je to naklikane behem 5ti minut, takze si s tim muzes vyhrat lepe. Hodnoty se zadavaji do JTable, po stisku tlacitka se obsah matice vypise na konzoli. Rozmery matice jsou v konstantach na zacatku. Pokud je tam chybny vstup, doplni se nula.

Kód:

/* * Qwert.java * * Created on 9. květen 2004, 10:24 */ /** * * @author user */ public class Qwert extends javax.swing.JDialog { private static final int COLS = 5; private static final int ROWS = 10; /** Creates new form Qwert */ public Qwert(java.awt.Frame parent, boolean modal) { super(parent, modal); initComponents(); initComponents2(); } private void initComponents2() { setupTable(ROWS,COLS); } protected int[][] createArray() { try { int rows = jTable1.getRowCount(); int cols = jTable1.getColumnCount(); int[][] ret = new int[rows][cols]; for(int i=0; i<rows; i++) for(int j=0; j<cols; j++) { int value; Object oValue = jTable1.getValueAt(i,j); try { value = (oValue!=null) ? Integer.parseInt(jTable1.getValueAt(i,j).toString()) : 0; } catch (NumberFormatException nfe) { value = 0; } ret[i][j] = value; } return ret; } catch (Exception e ) { e.printStackTrace(); return null; } } protected void test() { int[][] matice = createArray(); for(int i=0; i<matice.length; i++) { int[] row = matice[i]; for(int j=0; j<row.length; j++) { System.out.print(row[j]+"|\t"); } System.out.println(""); } } protected void setupTable(int _rows, int _cols) { Object[][] aoData = new Object[_rows][_cols]; String[] aCols = new String[_cols]; for(int i=0; i<_cols; i++) aCols[i] = Integer.toString(i); jTable1.setModel(new javax.swing.table.DefaultTableModel( aoData, aCols )); } /** This method is called from within the constructor to * initialize the form. * WARNING: Do NOT modify this code. The content of this method is * always regenerated by the Form Editor. */ private void initComponents() { jPanel1 = new javax.swing.JPanel(); jButton1 = new javax.swing.JButton(); jScrollPane1 = new javax.swing.JScrollPane(); jTable1 = new javax.swing.JTable(); addWindowListener(new java.awt.event.WindowAdapter() { public void windowClosing(java.awt.event.WindowEvent evt) { closeDialog(evt); } }); jPanel1.setLayout(new java.awt.FlowLayout(java.awt.FlowLayout.RIGHT)); jButton1.setText("nacti"); jButton1.addActionListener(new java.awt.event.ActionListener() { public void actionPerformed(java.awt.event.ActionEvent evt) { jButton1ActionPerformed(evt); } }); jPanel1.add(jButton1); getContentPane().add(jPanel1, java.awt.BorderLayout.NORTH); jScrollPane1.setViewportView(jTable1); getContentPane().add(jScrollPane1, java.awt.BorderLayout.CENTER); java.awt.Dimension screenSize = java.awt.Toolkit.getDefaultToolkit().getScreenSize(); setBounds((screenSize.width-200)/2, (screenSize.height-250)/2, 200, 250); } private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) { // Add your handling code here: test(); } /** Closes the dialog */ private void closeDialog(java.awt.event.WindowEvent evt) { //setVisible(false); System.exit(0); } /** * @param args the command line arguments */ public static void main(String args[]) { new Qwert(new javax.swing.JFrame(), true).show(); } // Variables declaration - do not modify private javax.swing.JButton jButton1; private javax.swing.JPanel jPanel1; private javax.swing.JScrollPane jScrollPane1; private javax.swing.JTable jTable1; // End of variables declaration }
