在我的应用程序中，我有一个表格视图。当用户双击某行时，有关该行的某些详细信息应显示在单独的详细信息窗口中。不知何故，它不起作用。我尝试了此站点的一些建议，但对我没有任何帮助。
我得到的错误：

这是我的双击侦听器：
tvReports.setRowFactory(new Callback<TableView<Report>, TableRow<Report>>() {
@Override
public TableRow<Report> call(TableView<Report> tv) {
TableRow row = new TableRow();
row.setOnMouseClicked(new EventHandler<MouseEvent>() {
public void handle(MouseEvent event) {
if (event.getClickCount() == 2 && (!row.isEmpty())) {
try {
openReport();
} catch (IOException e) {
e.printStackTrace();
}
}
}
});
return row;
}
});
openReport方法：
void openReport() throws IOException {
Report report = tvReports.getSelectionModel().getSelectedItem();
FXMLLoader fxmlLoader = new FXMLLoader(getClass().getResource("/View/ReportPositions.fxml"));
ReportPositions_Controller controller = fxmlLoader.getController();
controller.setPathDB(pathDB);
controller.setReport(report);
Parent root =(Parent) fxmlLoader.load();
Stage stage = new Stage();
stage.initModality(Modality.WINDOW_MODAL);
stage.initStyle(StageStyle.UNDECORATED);
stage.setTitle("Reportpositions");
stage.setScene(new Scene(root));
stage.show();
}
“我的详细信息控制器”窗口
public class ReportPositions_Controller {
@FXML
private TableView tvReportPositions;
ObservableList<ObservableList> data;
private Report report;
private String pathDB;
public ReportPositions_Controller(Report report, String pathDB){
this.report = report;
this.pathDB = pathDB;
}
public void initialize() throws SQLException {
buildData(); //method that gets the the data which should be displayed afterwards
}
}
ReportPositions.fxml
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.control.TableView?>
<TableView fx:id="tvReportPositions" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="400.0" prefWidth="600.0" xmlns="http://javafx.com/javafx/8.0.141" xmlns:fx="http://javafx.com/fxml/1" fx:controller="Controller.ReportPositions_Controller" />
我想将报告传递给控制器以获取报告的详细信息。
谢谢您的帮助
