Question

我有一个包含Piles TableView的javaFX 8窗格。当我从TableView中选择一个桩时，它会查询数据库并使用LogExt实例填充第二个TableView。第二个TableView包含一列映射到LogExt.selected布尔属性的复选框。

当我运行应用程序时，我无法选择任何复选框。

LogExt：

public class LogExt {
    private BooleanProperty selected = new SimpleBooleanProperty();
    private Log log;

    public LogExt(Log log) {
        this.setSelected(false);
        this.log = log;
    }

    public boolean isSelected() {
        return selected.get();
    }

    public BooleanProperty selectedProperty() {
        return selected;
    }

    public void setSelected(boolean selected) {
        this.selected.set(selected);
    }

    public Log getLog() {
        return log;
    }

    public void setLog(Log log) {
        this.log = log;
    }
}

控制器：

public class CustomOrderController {
    @FXML
    private RadioButton openRadio;
    @FXML
    private ToggleGroup stageGroup;

您需要在桌面上启用编辑功能。

logTable.setEditable(true);

也可能在你的专栏上

selectedCol.setEditable(true);

为什么我不能在tableview中选中一个复选框？
