bool qVariantCanConvert ( const QVariant & value )
Returns true if the given value can be converted to the template type specified; otherwise returns false.
This function is equivalent to QVariant::canConvert(value).
Note: This function was provided as a workaround for MSVC 6 which did not support member template functions. It is advised to use the other form in new code.
See also QVariant::canConvert().
T qVariantValue ( const QVariant & value )
Returns the given value converted to the template type T.
This function is equivalent to QVariant::value<T>(value).
Note: This function was provided as a workaround for MSVC 6 which did not support member template functions. It is advised to use the other form in new code.
See also QVariant::value() and qvariant_cast().
