Returns true if \a v1 and \a v2 are equal; otherwise returns false.
If \a v1 and \a v2 have the same \l{QVariant::}{type()}, the
type's equality operator is used for comparison. If not, it is
attempted to \l{QVariant::}{convert()} \a v2 to the same type as
\a v1. See \l{QVariant::}{canConvert()} for a list of possible
conversions.

@ -2817,8 +2823,13 @@ bool QVariant::convert(const int type, void *ptr) const
Compares this QVariant with \a v and returns true if they are
equal; otherwise returns false.
In the case of custom types, their equalness operators are not called.
Instead the values' addresses are compared.
QVariant uses the equality operator of the type() it contains to
check for equality. QVariant will try to convert() \a v if its
type is not the same as this variant's type. See canConvert() for
a list of possible conversions.
