I am creating an address book, and I have a lot of the functionality in place. However, the actual table cannot be seen. The data is there. I can save it and load it, but I can't actually see any data. I have tried lots of things, the setContentPane()
is being one. I have also spent time on the Oracle website, but to no avail. I have the sample table which shows the table, and tried to copy some code, but again, no avail.
public AddressBookGUI()
{
/*

addresses = new ArrayList<Person>();
Person a = new Person("Kathy", "Smith", "1 mith Sqaoiudh", "Lonodn", "London", "BN76 8QQ", "01980472", "LKSJ@kied.con");
addresses.add(a);
addressBook = new AddressBook(addresses, columnNames);
// JTable addressTable = new JTable(new TableModel());
//addressTable.setModel(new addressTable.TableModel());

createEditAddressFrame();

Comment-in this statement so that a TableModel
is set for the JTable
myTable
//myTable.setModel(addressBook);
Ensure that AddressBook
is indeed a functioning custom TableModel
