Use JavaFX FileChooser to open image file, and display on ImageView

The example demonstrate how to implement JavaFX FileChooser to open image file (jpg or png), and display it in a ImageView.

            } catch (IOException ex) {
                Logger.getLogger(JavaFXPixel.class.getName()).log(Level.SEVERE, null, ex);


- Make ImageView scrollable, in ScrollPane.
- Auto fit JavaFX 2 ImageView
- Load image file as InputStream

  2. Neither it doesn't work nor it does't give an error :/

  3. Thanks a lot, this is a good example for JavaFX beginners :)

  4. Great tutorial.

    But how would one accomplish this with other file types, along with video and audio formats?

    I have built a media player that can run video and audio files, using the FileChooser.

    But your method seems to neither work or produce an error.

    I have coded two separate events for the "load" button. When I compile and run the program and open the FileChooser box, and choose the format(in this case, .JPEG), I can select a file but nothing appears on my scene, even though I explicitly added the ImageView instance to my Pane() class.

    Any ideas?

  5. How i can save this myImageView.setImage(image); on my database ?
