Q_DECLARE_METATYPE(T); error

[SentaVera]

source file

#include "message.h"

Message::Message()
{
}

Message::Message(const Message &other)
{
name_=other.name_;
}

Message::~Message()
{

}

Message::Message(const QString &name)
{
setName(name);
}

QString Message::getName() const
{
return name_;
}

void Message::setName(const QString &name)
{
name_ = name;
}

After some search on google, I had found the solution in other similar issue.. link

it seems that i need to include a header file of QMetaType, which the tutorial didnt mention about it. Strange thing macro is still defined without the header file..

thank anyway!

Strange thing macro is still defined without the header file..

It is not. Which is the error you got.

Because the compiler saw a function declaration, function name Q_DECLARE_METATYPE, one argument of type Message, but missing return type.
So it complained about the missing return type, said it would assume it and warning you that this is not specified standard behavior.

Cheers,
