如何正确处理SWT / JavaFX FXCanvas

Question

I have an SWT/JavaFX FXCanvas that uses a WebView as root (to its Scene) instance embedded into a custom Composite:

class MyComposite extends Composite {
   FXCanvas canvas = createFXCanvasWithWebView();

   dispose() {
      webView.load(null);
      canvas = null;
      super.dispose();
   }
}

Is this sufficient to clean up all used resources (especially loaded images in the used WebView instance)?

Answer 1

webView.getEngine().load(null); is more than enough.

canvas = null is redundant.
