IntelliJ IDEA 2024.1 Help

Create a new JavaFX project

JavaFX is a software platform that is used for developing desktop applications that can run across a wide variety of devices.

JavaFX support in IntelliJ IDEA includes code completion, search, navigation and refactoring in JavaFX-specific source files (including .fxml and JavaFX .css files), integration with JavaFX Scene Builder, JavaFX application packaging capabilities, and more.

Make sure the JavaFX plugin is enabled

To be able to work with JavaFX in IntelliJ IDEA, the JavaFX bundled plugin must be enabled:

  1. In the Settings dialog (Ctrl+Alt+S) , select Plugins.

  2. Switch to the Installed tab and make sure that the JavaFX plugin is enabled.

    If the plugin is disabled, select the checkbox next to it.

  3. Apply the changes and close the dialog. Restart the IDE if prompted.

Create a new project

When you create a new JavaFX project, IntelliJ IDEA generates a fully configured sample application.

  1. Launch IntelliJ IDEA.

    If the Welcome screen opens, click New Project. Otherwise, go to File | New | Project in the main menu.

  2. From the Generators list on the left, select JavaFX.

  3. Name the new project, change its location if necessary, and select a language, and a build system.

  4. In the Group field, specify the name of the package that will be created together with the project.

  5. From the JDK list, select the JDK that you want to use in your project.

    If the JDK is installed on your computer, but not defined in the IDE, select Add JDK and specify the path to the JDK home directory.

    If you don't have the necessary JDK on your computer, select Download JDK.

    Click Next.

Run the application

  1. Open the class, click the Run application icon in the gutter, and select Run 'HelloApplication.main()'.

    The IDE starts compiling your code.

  2. When the compilation is complete, the application window appears.

    This means that the project is configured correctly and everything works as it should.

When you clicked Run, IntelliJ IDEA created a temporary run configuration named after the HelloApplication class. You can view and edit this configuration: in the main menu, go to Run | Edit Configurations.
