JavaFX Scene Builder is a visual layout tool that allows developers and designers to quickly design JavaFX application user interfaces by dragging and dropping components. Since it generates .fxml files (standard XML), it separates the UI design from the application logic, adhering to the Model-View-Controller (MVC) pattern.
Go to Settings -> Languages & Frameworks -> JavaFX and set the path to the Scene Builder executable. You can then right-click any FXML file and select Open In Scene Builder .
So, if you see a tutorial from 2015 asking you to download scene_builder-2_0-windows-x64.msi , smile, nod, and then head over to Gluon’s website. Your future self—and your firewall—will thank you.
