I ahve a JTable that is supposed to be 2 columns (String, JComboBox). When i initialize the table everything looks good. As soon as a I select a value in the table the JComboBox cell aquires the data type of the selected item.
I want to keep the JCOmboBox there and have it fire the events of data change and the Table ignore data changes in that column and keep the ComboBox populated.
My table has this as an override
@Override
public TableCellEditor getCellEditor(int row, int column) {
Object value = super.getValueAt(row, column);
if (value != null) {
if (value instanceof JComboBox) {
return new DefaultCellEditor((JComboBox) value);
}
return getDefaultEditor(value.getClass());
}
return super.getCellEditor(row, column);
}
Implementation
JComboBox uploadBox = new JComboBox();
uploadBox.addItem(MyPanel.UPLOAD_OPTIONS.PROMPT);
uploadBox.addItem(MyPanel.UPLOAD_OPTIONS.UPLOAD);
uploadBox.addItem(MyPanel.UPLOAD_OPTIONS.DONT_UPLOAD);
Object[][] tableData = new Object[][]{
{"Upload data on save", uploadBox}
};
table.setModel(
new DefaultTableModel(tableData, new String[]{"Description", "Options"}) {
Class[] types = new Class[]{String.class, JComboBox.class};
boolean[] canEdit = new boolean[]{false, true};
@Override
public Class getColumnClass(int columnIndex) {
return types[columnIndex];
}
@Override
public boolean isCellEditable(int rowIndex, int columnIndex) {
return canEdit[columnIndex];
}
});
table.getColumnModel().getColumn(1).setCellRenderer(new TableCellRenderer() {
@Override
public Component getTableCellRendererComponent(JTable jtable, Object o, boolean bln, boolean bln1, int i, int i1) {
return (Component)o;
}
});
