InApp Purchasing C++ not working in Qt 5.11.1 on Mac OS 10.13.6

Nando

Hi,
i try to implement an In-App-Purchase on Mac OS (10.13.6) with the qt purchase module.

I do the following:

    m_iapStore = new QInAppStore(this);

    connect(m_iapStore, SIGNAL(productRegistered(QInAppProduct*)),
            this, SLOT(markProductAvailable(QInAppProduct*)));
    connect(m_iapStore, SIGNAL(productUnknown(QInAppProduct::ProductType, const QString &)),
            this, SLOT(handleErrorGracefully(QInAppProduct::ProductType, const QString &)));
    connect(m_iapStore, SIGNAL(transactionReady(QInAppTransaction*)),
            this, SLOT(handleTransaction(QInAppTransaction*)));


void InAppPurchaseManager::markProductAvailable(QInAppProduct *product)
{
    m_inAppFullVersionProduct = product;
    qInfo() << "InAppPurchaseManager::markProductAvailable: product: " << m_inAppFullVersionProduct;

}

void InAppPurchaseManager::handleErrorGracefully(QInAppProduct::ProductType productType, const QString &identifier)
{
    qInfo() << "InAppPurchaseManager::handleErrorGracefully: productType:" << productType << " id: " << identifier;

}

void InAppPurchaseManager::handleTransaction(QInAppTransaction *transaction)
{
    qInfo() << "InAppPurchaseManager::handleTransaction: transaction: " << transaction;

}

    qInfo() << "InAppPurchaseManager::call registerProduct";
    m_iapStore->registerProduct(QInAppProduct::Consumable, QStringLiteral("de.myproduct.inapp-id"));

Documentation says:
Registering a product is asynchronous, and will at some point yield one of the following two signals: 1. productRegistered() if the product was found in the external store with a matching type. 2. productUnknown() if the product was not found in the external store with the type you specified.

But i do not get any answer / slot called after calling the registerProduct method.
I would expect that either the productUnknown or the productRegistered slot gets called, but nothing happens...

Any ideas, what the problem could be?

Greetings

Hi
first step is to check return of the connects to see they all return true .

Hi and thank you.
I chekced connect calls and all look good:

if(!connect(m_iapStore, SIGNAL(productRegistered(QInAppProduct*)),
            this, SLOT(markProductAvailable(QInAppProduct*))))
    {
        qCritical() << "connect failed: productRegistered";
    }
    else {
        qInfo() << "connect OK: productRegistered";
    }

    if(!connect(m_iapStore, SIGNAL(productUnknown(QInAppProduct::ProductType, const QString &)),
            this, SLOT(handleErrorGracefully(QInAppProduct::ProductType, const QString &))))
    {
        qCritical() << "connect failed: productUnknown";
    }
    else {
        qInfo() << "connect OK: productUnknown";
    }


    if(!connect(m_iapStore, SIGNAL(transactionReady(QInAppTransaction*)),
            this, SLOT(handleTransaction(QInAppTransaction*))))
    {
        qCritical() << "connect failed: transactionReady";
    }
    else {
        qInfo() << "connect OK: transactionReady";
    }

Any other ideas why the slots get not called?
I call this code from my MainWindow constructor.

Puuh, i can not get it working in my project :-(

Somehow no signals are emitted from the QInAppStore module on MacOS.
I checked it the signals are connected correctly.

Maybe i need to add something extra in Info.plist?

Same code in a mini test-project runs fine (but without app bundle, just normal app)
Something in my app seems to block the QInAppStore class to emit signals.
But i use signals slots all over my app and all work perfectly. Only QInAppStore seems not to emit the signals productUnknown(QInAppProduct::ProductType, const QString &)

@Nando
sadly i have no idea.
Do you use commercial version of Qt ?

SGaist

Hi,

Can you provide a minimal buildable example that shows that behaviour ?

version of Qt ?

Hi, for my tests i use the open source version.
