Description
Consider a simple example:
const auto tryType = [](int targetTypeId)
{
auto v = QVariant::fromValue(123);
Q_ASSERT(v.convert(targetTypeId));
qDebug() << v << "can convert to string:" << v.canConvert(QMetaType::QString);
};
tryType(QMetaType::Short);
tryType(QMetaType::UShort);
tryType(QMetaType::Int);
tryType(QMetaType::UInt);
tryType(QMetaType::Long);
tryType(QMetaType::ULong);
tryType(QMetaType::LongLong);
tryType(QMetaType::ULongLong);
We can expect to see true for all types but instead we see:
QVariant(short, 123) can convert to string: true
QVariant(ushort, 123) can convert to string: true
QVariant(int, 123) can convert to string: true
QVariant(uint, 123) can convert to string: true
QVariant(long, 123) can convert to string: false
QVariant(ulong, 123) can convert to string: false
QVariant(qlonglong, 123) can convert to string: true
QVariant(qulonglong, 123) can convert to string: true
