Study Notes
Creating Multi-Scene Java FX Applications
- To create a multi-scene application in Java FX, use NetBeans to create new fxml view files.
- Edit these files using SceneBuilder.
- Save the edited files.
- Create controllers for each of these views in NetBeans and save them to the source folder.
- Create a new "images" resource folder and save resources to that folder.
- Create a public static method or field in the initial viewController.
- The secondary viewController should have a private field that is set based on the initial viewController.
Packaging Java FX Applications
- Java FX applications can be packaged as a self-contained application JAR file.
- The JAR file will include compiled class files, application resources, and a launcher.
- The Java and Java FX runtimes are included. Java runtime version can be fully controlled by the application developer.
- JavaFX applications can be packaged in NetBeans by using the Maven FXML project type.
- Utilize the "Clean and Build" command to package the Java FX application.
- Resources should be saved in the project src/main/resources folder to be included in the JAR file.
Creating a Self-Contained Jar File
- Create a new class named "Main" that extends Application.
- This main class cannot extend any class besides Object.
- Update the maven-shade-plugin to point to the new "Main" class.
- Change the project configuration to "release-profile."
- "Clean and Build" the project.
- The packaged JAR file will be located in the project's target folder, and can be run by double clicking on the JAR file.
