Hi,
I have the following piece of code:
QVector<int> CompatibilityInterfaceImpl::getActionIds() const
{
return _actions.keys().toVector(); // _actions is a QHash
}
In Qt Creator this generates the following warning:
allocating an unneeded temporary container [clazy-container-anti-pattern]
How can I avoid the warning in this case?
I am using Qt 5.12, so I return a QVector instead of a QList because
using the old (Qt 5) QList is discouraged. Unfortunately many Qt API's
still use QList for nearly everything, so I am faced with a difficult
choice:
1) go back to using QList
2) deal with warnings and/or write my own conversion functions that
are probably not very efficient
Or is there another (convenient) way to solve this that I am not aware of?
Migrating to Qt 6 is not an option right now.
Thanks,
Kevin
