Я пытаюсь поместить панель стека в свой TableView и продолжаю получать ошибки.
Я подозреваю, что это мое непонимание создания Cell Value Factory.
Мой код выглядит так:
TableColumn obj = new TableColumn("Func " + i);
final int index = i;
obj.setCellValueFactory(new Callback<TableColumn.CellDataFeatures<ObservableList<String>, String>, TableCell<ObservableList<String>, String>>() {
@Override
public TableCell<ObservableList<String>, String> call(final CellDataFeatures<ObservableList<String>, String> cdf) {
if (index + 2 >= cdf.getValue().size()) {
return null;
}
//return new SimpleStringProperty(cdf.getValue().get(index + 2));
return new TableCell<ObservableList<String>, String>(){
Label funcLbl = new Label(cdf.getValue().get(index+2));
StackPane sp = new StackPane();
@Override
protected void updateItem(String item, boolean empty) {
super.updateItem(item, empty); //To change body of generated methods, choose Tools | Templates.
sp.getChildren().add(funcLbl);
setGraphic(sp);
}
};
}
});
obj.setMinWidth(100);
this.getColumns().add(obj);
И ошибка, которую я получаю,
SEVERE: javafx.scene.control.Control loadSkinClass Failed to load skin 'StringProperty [bean: PinTable[id=null, styleClass=table-view], name: skinClassName, value: com.sun.javafx.scene.control.skin.TableViewSkin]' for control PinTable[id=null, styleClass=table-view]

Я пытаюсь преобразовать использование
public ObservableValue<String> call(CellDataFeatures<ObservableList<String>, String> cdf)
и возвращает только SimpleStringProperty для возврата TableCell<ObservableList<String>, String>, который имеет StackPane в качестве своего содержимого с String, содержащимся в Label (я хочу создавать действия, основанные на нажатии на панель стека).
Любая помощь в понимании перехода была бы здорово!
