刚接触Qt，做个全局热键时，按照网上的资料照抄，可是一直出错，请教！
两个错误：
1. no mach for 'operateor==' (operand types are 'const QByteArray' and const char [20]')
2. invalid operand to binary expression ( 'const QByteArray' and const char [20]')
bool MyWinEventFilter::nativeEventFilter(const QByteArray &eventType, void *message, long *){if(eventType == "windows_generic_MSG"){
}return false;}
