我想单独用Xlib 里面的XSendEvent()接口做一个linux下的一个用java做的软键盘大家都来看看

[t355402]

我到http://tronche.com/gui/x/xlib/event-handling/XSendEvent.html网上面看了下有关XSendEvent()的说明，可我就是不能得到我想要模拟键盘的效果,我把代码发给大家看看.软键盘的界面是我用java swt做的，现在它功能要用低层C来实现。我原来的想法是从java里面得到哪个按键被触发，然后我在把该key对应在linux下的key value(比如XK_1)扔到这个方法里面，然后再把要发送的焦点windowID也扔进去。这样就可以模拟键盘的输入效果。可我都试了好几天没怎么用。哪个能指点我下哦。
这是C文件里面的代码：
