这是JavaFX2版本（使用Stage而不是Window）：
private static Pointer getWindowPointer(Stage stage) { try { TKStage tkStage = stage.impl_getPeer(); Method getPlatformWindow = tkStage.getClass().getDeclaredMethod("getPlatformWindow" ); getPlatformWindow.setAccessible(true); Object platformWindow = getPlatformWindow.invoke(tkStage); Method getNativeHandle = platformWindow.getClass().getMethod( "getNativeHandle" ); getNativeHandle.setAccessible(true); Object nativeHandle = getNativeHandle.invoke(platformWindow); return new Pointer((Long) nativeHandle); } catch (Throwable e) { System.err.println("Error getting Window Pointer"); return null; }}
