Questions tagged [javafx]

The JavaFX platform enables developers to create and deploy Graphical User Interface (GUI) applications that behave consistently across multiple platforms. It is built on java technology and was part of the Oracle JDK from JDK 8 until Java 10. Since JDK 11, JavaFX is shipped as a library, independent of most JDK and JRE distributions.
