qt pass custom structure parameters in different threads

If the functions of the qt program are all in the main thread, the custom structure can be passed.
eg

struct Student{QString name;int ID;}//Assume from form a to form b, all in the main threadconnect(a,&A::sSendStudent,b,&B::receiverStudent);//This can be passed.

But when different threads can not pass.
This problem occurs

QObject::connect: Cannot queuearguments of type 'Student'

Solution
Include in the file that sends the signal

#include 

Then add in the constructor:

qRegisterMetaType<Student>("Student");

For the record only.
