swt.win32.extension的问题,高手进

swt.win32.extension.hook的高级钩子效果不错,但是低级钩子就不懂了,首先试了JournalPlaybackHook,编译通过,但运行显示WIN7不支持,是的么?接着就是Keyboard_LLHook低级键盘钩子失灵,看了包的源代码,感觉不可能写错了,有人知道怎么解决么?//        Keyboard_LLHookInterceptor kllh = new Keyboard_LLHookInterceptor() {
//
//            @Override
//            public InterceptorFlag intercept(Keyboard_LLHookData kllhd) {
//                switch (kllhd.getWParam()) {
//                    case Keyboard_LLHookData.WM_SYSKEYDOWN:
//                    case Keyboard_LLHookData.WM_SYSKEYUP:
//                        return InterceptorFlag.FALSE;
//                    case Keyboard_LLHookData.WM_KEYDOWN:
//                    case Keyboard_LLHookData.WM_KEYUP:
//                        return InterceptorFlag.TRUE;
//                }
//                return InterceptorFlag.FALSE;
//            }
//        };
//        Keyboard_LLHook.addHookInterceptor(kllh);
//        Keyboard_LLHook.installHook();因为运行没效果,这些都注释了,求高手
