Hallo ich habe folgenden Code in meiner JTable integriert und wollte jetzt gerne wissen wie man die Radiobuttons aus einer Methode setzen kann. Probiere schon ne weile rum aber ich bin noch zu frisch in Java um das ganze 100%ig nachzuvollziehen.
Dankeschön

class RadioButtonRenderer implements TableCellRenderer {
public Component getTableCellRendererComponent(JTable table, Object value,
boolean isSelected, boolean hasFocus, int row, int column) {
if (value==null) return null;
return (Component)value;
}
}

private JRadioButton button;

super(checkBox);
}
public Component getTableCellEditorComponent(JTable table, Object value,

button = (JRadioButton)value;
button.addItemListener(this);
return (Component)value;

button.removeItemListener(this);
return button;

super.fireEditingStopped();

public JRadioButtonTableExample(){
super( "JRadioButtonTable Example" );

UIManager.put("RadioButton.focus", ui.getColor("control"));
DefaultTableModel dm = new DefaultTableModel();
dm.setDataVector(
new Object[][]{
{"Group 1",new JRadioButton("A")},
{"Group 1",new JRadioButton("B")},
{"Group 1",new JRadioButton("C")},
{"Group 2",new JRadioButton("a")},

new Object[]{"String","JRadioButton"});
JTable table = new JTable(dm) {
public void tableChanged(TableModelEvent e) {
super.tableChanged(e);
repaint();
}
};
ButtonGroup group1 = new ButtonGroup();
group1.add((JRadioButton)dm.getValueAt(0,1));
group1.add((JRadioButton)dm.getValueAt(1,1));
group1.add((JRadioButton)dm.getValueAt(2,1));
ButtonGroup group2 = new ButtonGroup();
group2.add((JRadioButton)dm.getValueAt(3,1));
group2.add((JRadioButton)dm.getValueAt(4,1));
table.getColumn("JRadioButton").setCellRenderer(new RadioButtonRenderer());
table.getColumn("JRadioButton").setCellEditor(new RadioButtonEditor(new JCheckBox()));
JScrollPane scroll = new JScrollPane(table);
getContentPane().add( scroll );
setSize( 200, 140 );
setVisible(true);
}
public static void main(String[] args) {
JRadioButtonTableExample frame = new JRadioButtonTableExample();
frame.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
System.exit(0);
}
});
}
}
Dankeschön
