如何在 JavaFX 中将复选框添加到 TableView

在我的 Java 桌面应用程序中，我有一个 TableView，我想在其中有一列带有复选框。

我确实找到了这样做的地方http://www.jonathangiles.net/javafx/2.0/CellFactories/ http://www.jonathangiles.net/javafx/2.0/CellFactories/但由于无法下载，而且我不知道乔纳森·贾尔斯 (Jonathan Giles) 多久会回复我的电子邮件，我想我应该问一下……

如何将复选框放入 TableView 的单元格中？

Uses javafx.scene.control.cell.CheckBoxTableCell<S,T> http://docs.oracle.com/javafx/2/api/javafx/scene/control/cell/CheckBoxTableCell.html工作完成了！

  ObservableList< TableColumn< RSSReader, ? >> columns =
     _rssStreamsView.getColumns();
  [...]
  TableColumn< RSSReader, Boolean > loadedColumn = new TableColumn<>( "Loaded" );
  loadedColumn.setCellValueFactory(
    new Callback<CellDataFeatures<RSSReader,Boolean>,ObservableValue<Boolean>>(){
        @Override public
        ObservableValue<Boolean> call( CellDataFeatures<RSSReader,Boolean> p ){
           return p.getValue().getCompleted(); }});
  loadedColumn.setCellFactory(
     new Callback<TableColumn<RSSReader,Boolean>,TableCell<RSSReader,Boolean>>(){
        @Override public
        TableCell<RSSReader,Boolean> call( TableColumn<RSSReader,Boolean> p ){
           return new CheckBoxTableCell<>(); }});
  [...]
  columns.add( loadedColumn );

UPDATE:相同的代码使用Java 8 lambda 表达式 http://docs.oracle.com/javase/tutorial/java/javaOO/lambdaexpressions.html

  ObservableList< TableColumn< RSSReader, ? >> columns =
     _rssStreamsView.getColumns();
  [...]
  TableColumn< RSSReader, Boolean > loadedColumn = new TableColumn<>( "Loaded" );
  loadedColumn.setCellValueFactory( f -> f.getValue().getCompleted());
  loadedColumn.setCellFactory( tc -> new CheckBoxTableCell<>());
  [...]
  columns.add( loadedColumn );

行数除以二！ (16==>8)

UPDATE:相同的代码使用Java 10“var”上下文单词 http://openjdk.java.net/jeps/286

  var columns = _rssStreamsView.getColumns();
  [...]
  var loadedColumn = new TableColumn<RSSReader, Boolean>( "Loaded" );
  loadedColumn.setCellValueFactory( f -> f.getValue().getCompleted());
  loadedColumn.setCellFactory( tc -> new CheckBoxTableCell<>());
  [...]
  columns.add( loadedColumn );
