• FXCanvasEx provides workarounds for the following issues: • JDK-8143596: Forward touch gestures to FXCanvas embedded scene.

• JDK-8161282: FXCanvas does not forward horizontal mouse scroll events to the embedded scene.

• JDK-8088147: Image cursors not supported.

• JDK-8159227: KeyEvent.doit should be forwarded to KeyEvent.consumed().

• JDK-8161587: FXCanvas does not update SWT display.

• JDK-8088862: Provide possibility to traverse focus out of FX scene.

• Fixes for those requiring access to JDK-internals have been contributed to OpenJFX 9 directly.

• FXCanvasEx can now transparently be used for Java 8 and 9.
