Class QVariant

java.lang.Object

io.qt.core.QVariant

public final class QVariant
extends Object

The QVariant class contains a set of static methods to convert between datatypes.

You can check with this class whether a datatype can be converted to another. This is datatypes which cannot simply be cast to each other, but requires processing to convert, i.e., you cannot use the instanceof operator as you would for classes with the same super class.
