Одна из вещей, которые мне нравится делать, - создавать опции в контекстном меню, вызываемом правой кнопкой мыши.
Код ключа:
//Use setRowFactory to set up the ContextMenu
table.setRowFactory(new Callback<TableView<Person>, TableRow<Person>>()
{
@Override
public TableRow<Person> call(TableView<Person> tableView)
{
final TableRow<Person> row = new TableRow<>();
final ContextMenu contextMenu = new ContextMenu();
final MenuItem copyItem = new MenuItem("copy index and first name");
copyItem.setOnAction(new EventHandler<ActionEvent>()
{
@Override
public void handle(ActionEvent event)
{
final Clipboard clipboard = Clipboard.getSystemClipboard();
final ClipboardContent content = new ClipboardContent();
Person tempPerson = row.getItem();
//Put the row index and first name in clipboard
content.putString(row.getIndex() + ". " + tempPerson.getFirstName());
clipboard.setContent(content);
}
});
contextMenu.getItems().add(copyItem);
// Set context menu on row, but use a binding to make it only show for non-empty rows:
row.contextMenuProperty().bind(
Bindings.when(row.emptyProperty())
.then((ContextMenu) null)
.otherwise(contextMenu)
);
return row;
}
});
