将T的集合转换为Qt中的QVariant的集合

Question

In Qt, how can I convert a typed collection of objects such as a QList<T> into a QList<QVariant> ? I suppose I could construct a new list and copy the elements over, converting each to a QVariant along the way, but is there a shortcut?

Answer 1

Thanks to the Qt IRC chat room. It was staring me right in the face.

QList<MyClass> source = ...;
QVariant variant = QVariant::fromValue(source);

The variant here is a QList<QVariant> .
