Qt Mobility / Service Framework / complex parameters, structures

billouparis

Hello all,

I simply want to declare a service with a parameter of complex type (like a structure for example). I am working with remote services, to perform basic IPC.

When the service is called, it sends a signal in return with a parameter to the client. If this parameter is a simple type parameter like int for instance, the signal is correctly received by the client (the client is making a connection with the service signal).
If I introduce a struct parameter instead of the int parameter, then the client is never receiving the signal.

Do somebody know what I have to do so that my struct is correctly sent through the Qt Mobility Service Framework?

I even tried to declare my structure as a metatype to see if this helps, but it led to a segmentation fault!
The following code illustrate the segmentation fault case:
@struture.h
#include <QObject>
#include <QtCore/QMetaType>

struct t_monstruct {
t_monstruct() : a(0), b(0) {}
t_monstruct (const t_monstruct &other)
:
a(other.a), b(other.b)
{
}

int a;
int b;

} ;

Q_DECLARE_METATYPE(t_monstruct)

In the server.h:
#include "structure.h"
class CServer
...
void sgnInitialize(t_monstruct id)
...
in the server.cpp
CServer::CServer()
{
qRegisterMetaType<t_monstruct>("t_monstruct");
}
in the service slot method ()
{

    t_monstruct id;
    id.a = 10;
    id.b = 50;
    //returns a signal when the slot is called
    emit sgnInitialize(id);
 }

In the client.cpp
CClient::CClient()
{
qRegisterMetaType<t_monstruct>("t_monstruct");
QObject::connect(service,SIGNAL(sgnInitialize(t_monstruct)),
this,SLOT(sgnInitializelocal(t_monstruct)));
}

     CClient::sgnInitializelocal(t_monstruct id)
    {
         qDebug()<<id.a<<" "<<is.b;
    }

Thank you,
