Netbeans JComboBox java.lang.ClassCastException
Bojour,
je suis confronté à une erreur avec JTable, JComboBox.
J'ai crées un JTable basée sur une table operation (MYSQL).
Par défaut Netbeans n'utilise que des JTextField. Je veux mettre à la place d'un d'un JtextField un JComboxBox car certains éléments doivent être selectionnés et non saisis par l'utilisation (ces éléments proviennent des tables paramètres)
alors voici le code:
Code:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
| comboBox = new javax.swing.JComboBox();
comboBox.setName("comboBox"); // NOI18N
org.jdesktop.swingbinding.JComboBoxBinding jComboBoxBinding1 = org.jdesktop.swingbinding.SwingBindings.createJComboBoxBinding(org.jdesktop.beansbinding.AutoBinding.UpdateStrategy.READ_WRITE, structureList, comboBox);
bindingGroup.addBinding(jComboBoxBinding1);
// Code adding the component to the parent container - not shown here
comboBox.setRenderer(new DefaultListCellRenderer() {
@Override
public Component getListCellRendererComponent(
JList list, Object value, int index, boolean isSelected, boolean cellHasFocus) {
super.getListCellRendererComponent(list, value, index, isSelected, cellHasFocus);
if (value instanceof Structure) {
Structure s = (Structure)value;
setText(s.getCode());
}
return this;
}
});
masterTable.getColumnModel().getColumn(0).setCellEditor(new DefaultCellEditor(comboBox));
masterScrollPane.setViewportView(masterTable); |
A l'exécution j'ai l'erreur suivante quand je sélectionne un élément dans la JComboBox :
