通过FXML的JavaFX ImageView不起作用 [英] JavaFX ImageView via FXML does not work

问题描述

我在FXML上使用ImageView加载图像时遇到问题.

I have a problem with loading Images with ImageView on FXML.

我的控制器类:

public class BoxViewController {
    @FXML
    private Label label_boxID;

    @FXML
    private ImageView boximage;

    public void initData(ObservableList<BoxProperty> observableList,
                         BoxService sBox, 
                         TableView tableview) {
        this.label_boxID.setText(
            String.valueOf(this.boxproperty.getPboxid()));

        Image image = new Image("boximage.jpg");
        this.boximage = new ImageView();
        this.boximage.setImage(image);
    }
}

因此，使用文本设置标签是可行的，但是图像不会出现在我的ImageView中. 对于ImageView，我向FXML文件添加了一个ID:

So, setting the label with a text works, but the image won't appear in my ImageView. For the ImageView, I added an ID to the FXML file:

 <ImageView fx:id="boximage" 
            disable="false" 
            fitHeight="150.0" fitWidth="200.0"
            layoutX="69.0" layoutY="322.0" 
            pickOnBounds="true" 
            preserveRatio="true" />

我很困惑为什么这不能正常工作，因为标签可以工作，但是图像无法加载.
我还检查了boximage是否不为null，但不是.也没有例外.

I'm confused why this is not working because the label works, but the image won't load.
I also checked whether boximage isn't null, but it isn't. There are also no Exceptions.

推荐答案

这有效:

BufferedImage bufferedImage;
bufferedImage = ImageIO.read(new File(this.path));
Image image = SwingFXUtils.toFXImage(bufferedImage, null);
this.boximage.setImage(image);
