qobject_cast and sender()

[ksrarc]

Hello,

Lets set this:

using namespace srps;
bool SRPSMain::initialize()
{
    QObject * obj = new Species;
    Species * sp = qobject_cast<Species*>( obj );
    sp->setObjectName("sp");
    qDebug() << obj << sp;
    connect( sp, SIGNAL(destroyed()), this, SLOT(deleted()) );
    sp->deleteLater();
    return true;
}
 
void SRPSMain::deleted()
{
    qDebug() << Q_FUNC_INFO << sender() << qobject_cast<Species*>( sender() );
}

using namespace srps;
bool SRPSMain::initialize()
{
    QObject * obj = new Species;
    Species * sp = qobject_cast<Species*>( obj );
    sp->setObjectName("sp");
    qDebug() << obj << sp;
    connect( sp, SIGNAL(destroyed()), this, SLOT(deleted()) );
    sp->deleteLater();
    return true;
}

void SRPSMain::deleted()
{
    qDebug() << Q_FUNC_INFO << sender() << qobject_cast<Species*>( sender() );
}

To copy to clipboard, switch view to plain text mode 

both classes are QObject direct subclases and have Q_OBJECT macro.

the output is:

srps::Species(0x82ab00, name = "sp") srps::Species(0x82ab00, name = "sp")
void srps::SRPSMain::deleted() QObject(0x82ab00, name = "sp") QObject(0x0)

srps::Species(0x82ab00, name = "sp") srps::Species(0x82ab00, name = "sp")
void srps::SRPSMain::deleted() QObject(0x82ab00, name = "sp") QObject(0x0)

To copy to clipboard, switch view to plain text mode 

so, why the second qobject_cast does not work?

Thanks.
