I would like to share my learning journey with JavaFX by demonstrating a small project in the form of a 'dock'. The goal of this project is to create a bar at the bottom of the screen where program icons can be placed and launched directly.
I came across this project as part of the Udemy course 'JavaFX - Creating Java programs with interfaces / GUIs'.
I developed my own interpretation and expanded and improved the project according to my ideas.
Creating a JavaFX project in IntelliJ is easy.
I'm following the MVC architecture, with separate packages for the model, view, and controller.
public class App extends Application { public void start(Stage stage) throws IOException { //MVC MyView view = new MyView(); MyController controller = new MyController(view); //JavaFX Scene scene = new Scene(view.getRoot(), 520, 240); stage.setTitle("Hello World!"); stage.setScene(scene); stage.show(); } public static void main(String[] args) { launch(); } }
public class MyView { private Group root = new Group(); private ImageView imageViewDock; private final String[] icons = {"Browser.png", "IDE.png", "Mail.png", "Text.png" }; private ArrayList iconsList = new ArrayList<>(); public MyView() { Image image = new Image(getClass().getResourceAsStream("/images/Dock.png")); //Dock imageViewDock = new ImageView(image); imageViewDock.setTranslateX(12); imageViewDock.setTranslateY(100); root.getChildren().add(imageViewDock); for(int i = 0; i < icons.length; i++){ IconImageView icon = new IconImageView(icons[i]); icon.setTranslateX(90+80 * i); icon.setTranslateY(100); icon.setEffect(new Reflection()); root.getChildren().add(icon); iconsList.add(icon); } }
I use the Group layout as the root element for my scene. Then I create an ImageView that contains my image for the dock.
Using a for loop, I created the icons and added them to the dock.
public class IconImageView extends ImageView { String path = ""; public IconImageView(String path) { this.path = path; Image image = new Image(getClass().getResourceAsStream("/images/" + this.path +"")); this.setImage(image); this.setScaleY(0.8); this.setScaleX(0.8);
For the icons, I created a custom IconImageView class where I defined default values and zoom in/out effects.
public class MyController { private MyView view; public MyController(MyView view) { this.view = view; DockHandler dockHandler = new DockHandler(); //Add Event Handler, exit by 2 clicks this.view.getImageViewDock().setOnMouseClicked(dockHandler.getMouseEventEventHandler()); //Add Event Handler Icons ArrayList iconsList = view.getIconsList(); for ( int i = 0; i < iconsList.size(); i++){ iconsList.get(i).setOnMouseClicked(new IconHandler(iconsList.get(i).getPath()).getEventHandler()); } } }
The controller connects my view with the model classes. The dockHandler terminates the program when you double-click on the dock.
public IconHandler(String path) { eventHandler = new EventHandler() { @Override public void handle(MouseEvent mouseEvent) { //Query operating system String os = System.getProperty("os.name").toLowerCase(); if (path.equals("Browser.png")){ System.out.println("Browser"); if(os.contains("win")){ String path = "C:\\Program Files\\Mozilla Firefox\\firefox.exe" ; startProgramm(path); }else if (os.contains("mac")) { String path = "open /Applications/Firefox.app" ; startProgramm(path); }else { System.out.println("Unsupported operating system"); } } else if
In IconHandler, check which operating system is used and then open the application for Mac or Windows.
//Transparent scene.setFill(Color.TRANSPARENT); stage.initStyle(StageStyle.TRANSPARENT); stage.show(); //Position //Screen Size Rectangle2D screenSize = Screen.getPrimary().getVisualBounds(); double x = (screenSize.getWidth() - stage.getWidth()) / 2; double y = screenSize.getHeight() - stage.getHeight() - 40; stage.setX(x); stage.setY(y); }
Finally, I implemented transparency and positioned the dock correctly on the screen.
Currently, some elements, such as paths and images, are still hard-coded. I plan to improve these areas to allow new icons to be added dynamically.
Thank you for reading this far! I'm still new to writing articles and have a lot to learn. I appreciate any feedback you may have. May the Force be with you. ?
