New in Qt 6.1: std::hash Support for QHash
In the previous blog post of this series, we discussed KDToolBox::QtHasher, a helper class that allows us to use unordered associative containers datatypes which have a qHash() overload but not a std::hash specialization. The majority of Qt value classes indeed are lacking such a specialization, even if they do provide a qHash() overload. For our […]

That post covered defining suitable geometry to draw a part of a circle, known also as a ‘sector’, efficiently, since such sectors occur commonly in instrument and vehicle interfaces. I started writing the second part, about […]
