static final javax.swing.JFrame getJFrame(final PSurface surf) {
  return
    (javax.swing.JFrame)
    ((processing.awt.PSurfaceAWT.SmoothCanvas)surf.getNative()).getFrame();
}

this bit of code in particular doesnt work with FX2D, is there any workaround?

static final javax.swing.JFrame getJFrame(final PSurface surf) {
  return
    (javax.swing.JFrame)
    ((processing.awt.PSurfaceAWT.SmoothCanvas)surf.getNative()).getFrame();
}

fixed,

saw another post about this exact thing on the forum, here is the complete code. Works in P2D AND FX2D, not sure about other renderers.
