JavaFx 2.x - Swing : Not on FX application thread

Question

I am trying to use JavaFx 2.x and Swing application by using a JInternalFrame in which attach a JFXPanel

My code below

public class InternalFrameWith         


        

Answer 1

See the 'JavaFX in Swing' tutorial. You are performing JavaFX operations which should run on the JavaFX thread on the Swing thread (Event Dispatch Thread).

Luckily they learnt from their previous mistakes and now throw exceptions when you perform operations on the wrong thread. That is the exception you encountered.

Use the Platform#runLater as shown in that tutorial

Platform.runLater(new Runnable() {
        @Override
        public void run() {
          //javaFX operations should go here
        }
   });

The construction of the JFXPanel can remain on the EDT (which is also illustrated in that tutorial)
