Question

我有一个TilePane，列出了我硬盘上不同目录的图像。我想，当点击TilePane上的图像时：

要打开包含图像的文件夹，
要打开图像，例如，使用默认程序设置打开该类型的图像文件。

到目前为止，我点击图片时只给了ImageResources/faviicon.png这样的内容。

我有什么方法可以使用，例如ImageResources/faviicon.png来做1.和2.上面？谢谢大家。

这是我所拥有的课程：

public class TilePaneExample extends Application {

    @Override
    public void start(Stage primaryStage) {
        VBox root = new VBox(30);

        String[] imageResources = new String[]{
            //loading images
            "ImageResources/facebook.png",
            "ImageResources/faviicon.png",
            "ImageResources/jquery-logo.png",
            "ImageResources/linkedin_32.png",
            "ImageResources/loading1.png",
            "ImageResources/twitter.png",
            "ImageResources/twitter_32.png",
            "ImageResources/wp.png",};

        VBox vb = new VBox(20);
        Text text4Tile = new Text("Images in TilePane");
        text4Tile.setFont(Font.font("Calibri", FontWeight.BOLD, 30));
        text4Tile.setUnderline(true);
        VBox.setMargin(text4Tile, new Insets(10, 0, 0, 10));

        //creating Flow Pane
        TilePane tilePane = new TilePane();
        tilePane.setHgap(5);
        tilePane.setVgap(5);

        for (final String imageResource : imageResources) {
            Image image = new Image(getClass().getResourceAsStream(imageResource));
            ImageView imageView = new ImageView(image);
            imageView.setOnMouseClicked(new EventHandler<MouseEvent>() {
                @Override
                public void handle(MouseEvent event) {
                    System.out.println("You clicked: " + imageResource);
                }
            });
            tilePane.getChildren().add(imageView);
        }

        vb.getChildren().addAll(text4Tile, tilePane);

        root.getChildren().addAll(vb);
        primaryStage.setTitle("TilePane Example");
        Scene scene = new Scene(root, 300, 150);
        primaryStage.setScene(scene);
        primaryStage.show();
    }

    public static void main(String[] args) {
        launch(args);
    }
}

更新

根据 DarkDarker的 建议，我这样做了：

imageView.setOnMouseClicked(new EventHandler<MouseEvent>() {
                @Override
                public void handle(MouseEvent event) {
                    try {
                        System.out.println("You clicked: " + imageResource);

                        File f = new File(imageResource);
                        System.out.println(f.getAbsolutePath());

                        Desktop.getDesktop().open(f.getParentFile());
                    } catch (IOException ex) {
                        Logger.getLogger(TilePaneExample.class.getName()).log(Level.SEVERE, null, ex);
                    }
                }
            });

java.lang.IllegalArgumentException: The file: ImageResources doesn't exist.

Answer 1

for (final String imageResource : imageResources) {
    String imagePath = getClass().getResource(imageResource).toExternalForm();
    ImageView imageView = new ImageView(new Image(imagePath));

    imageView.setOnMouseClicked(new EventHandler<MouseEvent>() {
        @Override
        public void handle(MouseEvent event) {
            System.out.println("You clicked: " + imagePath);
            File imageFile = new File(imagePath);
            Desktop.getDesktop().open(imageFile.getParentFile()); // open a folder in explorer 
            Desktop.getDesktop().open(imageFile); // open file with system preferred program
        }
    });
    tilePane.getChildren().add(imageView);
}
