Q_RETURN_ARG and void problem

[SABROG]

I want call slot after return to event loop like this:

QMetaObject::invokeMethod(this, "filterChanged", Qt::QueuedConnection
                                      , Q_RETURN_ARG(void, 0)
                                      , Q_ARG(QString, regexp));

QMetaObject::invokeMethod(this, "filterChanged", Qt::QueuedConnection
                                      , Q_RETURN_ARG(void, 0)
                                      , Q_ARG(QString, regexp));

To copy to clipboard, switch view to plain text mode 

But Q_RETURN_ARG don't accept arguments.

How to write a right?

Sorry, i found how this work, just need remove return argument:

QMetaObject::invokeMethod(this, "filterChanged", Qt::QueuedConnection
                                      , Q_ARG(QString, regexp));

QMetaObject::invokeMethod(this, "filterChanged", Qt::QueuedConnection
                                      , Q_ARG(QString, regexp));
