This VSCode extension provides support for FXML controllers in JavaFX projects.

fx:id errors.

Limitations
This plugin does not support references to event handlers using @FXML, and there are no plans to support them.
Please reference the element using fx:id and set the event handler in the controller class.
Requirements
- Java and FXML files must be located within the
src directory. For example, place Java files in src/main/java/com/example/FooController.java and FXML files in src/main/resources/com/example/foo.fxml.
fx:controller must be specified in the FXML file. FXMLLoader.setController() is not supported.- This extension will not function correctly unless there is a class in the project that extends
javafx.application.Application.
Restriction
This extension does not support FXML files that are loaded using fx:include.
