问题描述
我想创建一个 TableView 。在我的 .fxml 控制器中,我有以下两列:
I would like to create a TableView. In my .fxml controller, I have these two columns:
@FXML private TableColumn<Log, String> planeRegistrationColumn; @FXML private TableColumn<Log, String> planeTypeColumn;日志类的属性为 Plane 是一个Plane实例。但 setCellValueFactory 似乎不喜欢它:
The log class has an attribute Plane which is a Plane instance. But the setCellValueFactory doesn't seem to like it:
planeRegistrationColumn.setCellValueFactory(cellData -> cellData.getValue().planeProperty().get().getRegistration());getRegistration()返回一个字符串,但是它需要 ObservableValue< String> 。这是一个概念问题吗?如果没有,我该怎么做?
getRegistration() returns a String, but it needs an ObservableValue<String>. Is it a conception problem? And if not, how to can I do this?
推荐答案只需将你得到的字符串包装成某种可观察值:
Just wrap the string you get in some kind of observable value:
planeRegistrationColumn.setCellValueFactory(cellData -> new SimpleStringProperty(cellData.getValue().planeProperty().get().getRegistration()));更多推荐
将String转换为ObservableValue< String>
