求助 qt5.02移植tslib后，为何窗口程序接收不到任何鼠标事件

现在tsilb插件是正常加载了测试也成功，但触摸屏里qt程序还是接收不到任何事件，但我加入了调试信息，qt插件应该是接收到事件了，不知为何没有成功传递到窗口程序。。谁能帮我解决下，我对触屏这块不是很熟悉
QTsLibMouseHandler "tslib" "" 1
dev= "/dev/input/event0"
connect readMouseDate()
QTsLibMouseHandler "tslib" "" 1
dev= "/dev/input/event0"
connect readMouseDate()
event 我在窗口程序里重载了事件函数，窗口启动时打印出这些信息
event
event
event
begin readMouseDate!! 我点击了触摸屏大一出下面自己加入的调试信息，但窗口没收到任何事件
