ReplyDeleteThanks)))
ReplyDeleteNeither it doesn't work nor it does't give an error :/
ReplyDeleteRe-test on Ubuntu GNOME 15.10/NetBeans 8.1.
DeleteThanks a lot, this is a good example for JavaFX beginners :)
ReplyDeleteGreat tutorial.
ReplyDeleteBut 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?
thanks :)
ReplyDeleteHow i can save this myImageView.setImage(image); on my database ?
