Passing a pointer in Signal/Slot Connection

[momesana]

maybe you should try dynamic_cast<> and only access the data if the pointer to the casted object is valid. At least, that is the safest way to do a cast.

void DMXTable::SLOT_AllDMXPropsReceived( unsigned long u4member, void* pData )
{
    CDMXGateway* pNode = dynamic_cast<CDMXGateway*>( pData );
    if (pNode) {
            // Access data & crash
           SetDeviceName( pNode->GetDeviceName() );
           SetIPAddr( pNode->GetIPAddr() );
           ...
}

void DMXTable::SLOT_AllDMXPropsReceived( unsigned long u4member, void* pData )
{
    CDMXGateway* pNode = dynamic_cast<CDMXGateway*>( pData );
    if (pNode) {
            // Access data & crash
           SetDeviceName( pNode->GetDeviceName() );
           SetIPAddr( pNode->GetIPAddr() );
           ...
}
