Sometimes it is easier to grasp the concepts of a language or library such as JavaFX by seeing it in action. I’ve put together a JavaFX image converter application. This JavaFX app allows you to drag GIF’s, JPEG’s, BMP’s, or PNG’s onto the ImageView and then convert them and save them quickly as any of the other formats mentioned above.
This JavaFX app is a double-clickable JAR file. That means that if you want to run it from the JAR file, just make sure you have Java installed and double-click the JavaFX JAR named image-converter.jar.
If you deal with files in your JavaFX app, then you need to have drag and drop integration. You’ll be amazed at how easy drag-and-drop is in JavaFX.
The following JavaFX image drag-and-drop example only takes three files. You can just copy them into your JavaFX project, and run them if you’d like.
The resulting application allows you to drag an image file onto your window. As the image file moves over the window, it will change in a OS specific way, indicating that you can drop the file onto the open window. Once you drop the image file on to the window, the image will be displayed in the window. Continue reading “JavaFX Drag and Drop Images”
