如何向 TableView 行中的 JavaFx 按钮添加一些操作，以便在按下按钮时删除特定的 TableRow 和填充特定行的相应数据库表？
TableView 上的每一行都有自己的删除按钮。
这是我到目前为止所拥有的:
KiwiAction.setCellValueFactory(new PropertyValueFactory<NewBeautifulKiwi, Object>("KiwiAction"));
KiwiAction.setCellFactory(new Callback<TableColumn<NewBeautifulKiwi, Object>, TableCell<NewBeautifulKiwi, Object>>() {
@Override
public TableCell<NewBeautifulKiwi, Object> call(TableColumn<NewBeautifulKiwi, Object> param) {
final Button button;
Image image = new Image(getClass().getResourceAsStream("/MediaTools/Error.png"));
final ImageView imageView = new ImageView();
imageView.setFitHeight(16);
imageView.setFitWidth(16);
imageView.setImage(image);
button = new Button("", imageView);
final TableCell<NewBeautifulKiwi, Object> cell = new TableCell<NewBeautifulKiwi, Object>() {
@Override
public void updateItem(Object item, boolean empty) {
if (item != null) {
super.updateItem(item, empty);
final VBox vbox = new VBox(0);
button.setAlignment(Pos.CENTER);
button.maxWidth(32);
button.getStyleClass().add("deleteButton");
final TableCell<NewBeautifulKiwi, Object> c = this;
button.setOnAction(new EventHandler<ActionEvent>() {
@Override
public void handle(ActionEvent event) {
TableRow tableRow = c.getTableRow();
NewBeautifulKiwi item = (NewBeautifulKiwi) tableRow.getTableView().getItems().get(tableRow.getIndex());
Session session = HibernateUtil.getSessionFactory().openSession();
session.beginTransaction();
NewBeautifulKiwi toDelete = (NewBeautifulKiwi) session.get(NewBeautifulKiwi.class, item);
session.delete(toDelete);
session.getTransaction().commit();
session.flush();
session.close();
System.out.println("Deleted");
}
});
vbox.getChildren().add(button);
setGraphic(vbox);
}
}
};
cell.setGraphic(button);
return cell;
}
});
Kiwi.setCellValueFactory(new PropertyValueFactory<NewBeautifulKiwi, String>("Kiwi"));
任何帮助将不胜感激。这两天一直在做这个。
最佳答案
最明显的方法是从 ObservableList 中删除该项目或清除 ObservableList 并重新填充它，然后再次将此列表分配给表!
这会成功的!
-干杯!
