Configure JavaFX Scene Builder
IntelliJ IDEA allows you to open .fxml files in JavaFX Scene Builder right from the IDE so that you can visually design JavaFX interfaces directly.
Open files in Scene Builder in the IDE
When you open an .fxml file in the editor, there are two tabs underneath the editing area: the Text tab is for developing the markup, and the Scene Builder tab is for editing the file in Scene Builder.
Open an .fxml file in the editor.
Switch to the Scene Builder tab.
If your project doesn't have JavaFX Scene Builder, you will see a notification panel prompting you to install Scene Builder Kit.
Click Download Scene Builder Kit on the panel.
After that you can view .fxml files in Scene Builder right in the IDE by switching to the dedicated tab.
