Getting an integer from a vector-CodePudding

    Customer c = data.getCustomer(index.row());
    QString assetId = QString::fromStdString(c.getAssetId());
    QString name = QString::fromStdString(c.getName());
    QString price = QString::fromStdString(c.getPrice());
    QString quantity = QString::fromStdString(c.getQuantity());
    QString category = QString::fromStdString(c.getCategory());
    QString roomNumber = QString::fromStdString(c.getRoomNumber());

I am trying to get an integer from assetId, price, quantity, roomNumber.

I'm unsure what syntax to use to get the int from Qstring.

CodePudding user response：

You can use toInt member function of QString class

QString str = "10";
int i = str.toInt(); // now i is 10.

If you need to check if conversion was successful, you can also use additional bool to indicate success.

QString str = "not a number";
bool success;
int i = str.toInt(&success); // success is false, because conversion failed, i holds value 0.
