Qt出现错误QObject::connect: Cannot queue arguments of type 'QUuid'(Make sure 'string' is reg //QObject::connect: Cannot queue arguments of type 'UINT64'

转自CSDN:https://blog.csdn.net/qq575787460/article/details/8469240

例如以C++标准库中string做参数,则会出现:

QObject::connect: Cannot queue arguments of type 'string'

(Make sure 'string' is registed using qRegisterMetaType().)

 

解决方案:

可以再main中加入:

qRegisterMetaType<string>("string");注册该类型
