JavaFX的TableView中分页程序(JavaFX TableView Paginator)

在TableView中paginator.?.For如何使用这exmple ...

public class SampleController implements Initializable {

    @FXML private TableView<Student> table;
    @FXML private TableColumn<Student, Integer> id;
    @FXML private TableColumn<Student, String> name;
    @FXML private ObservableList<Student> list = FXCollections.observableArrayList();
    //  @FXML private Pagination pagination;
    // 
    private StudentSQL ssql = new StudentSQL();
    private Stage stage = new Stage();
    private String row;

    @Override
    public void initialize(URL url, ResourceBundle rb) {
        id.setCellValueFactory(new PropertyValueFactory<Student, Integer>("id"));
        name.setCellValueFactory(new PropertyValueFactory<Student, String>("name"));
        list = ssql.students();
        table.setItems(list);
    }
}

Answer 1:

你必须使用分页控制和实现网页的工厂。工厂要求应显示，你可以使用它的参数，该PageIndex的，提供项目到TableView中的子表的每一页：

TableView table = ...

private Node createPage(int pageIndex) {

    int fromIndex = pageIndex * rowsPerPage;
    int toIndex = Math.min(fromIndex + rowsPerPage, data.size());
    table.setItems(FXCollections.observableArrayList(data.subList(fromIndex, toIndex)));

    return new BorderPane(table);
}


@Override
public void start(final Stage stage) throws Exception {

    Pagination pagination = new Pagination((data.size() / rowsPerPage + 1), 0);
    pagination.setPageFactory(this::createPage);
    ...
}

下面是用于与分页控制集成的TableView一些示例代码。

代码来自沙基尔Quasaroff的回答了一个Oracle的JavaFX论坛请求PaginatedTableView控制。示例代码是纯Java解决方案，而不是一个Java代码/ FXML混合如在原来的问题。

Answer 3:

测试出在此线程产生的分页代码时，我发现了一个小问题。当数据==到一个在页面设置的行数的大小，会出现混乱（内页）。在这种情况下，创建一个额外的（空白）页面和数据拒绝出现在任何网页。我相信，下面的代码片段应该解决这个问题（其他人是否遇到相同的问题，因为我）。这段代码应该来声明分页变量之前。

int numOfPages = 1;
if (data.size() % rowsPerPage == 0) {
  numOfPages = data.size() / rowsPerPage;
} else if (data.size() > rowsPerPage) {
  numOfPages = data.size() / rowsPerPage + 1;
}
Pagination pagination = new Pagination((numOfPages), 0);
pagination.setPageFactory(this::createPage);

希望能帮助到你！
