QVariant qVariantFromValue(const T & value)
Returns a variant containing a copy of the given value with template type T.
This function is equivalent to QVariant::fromValue(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.
For example, a QObject pointer can be stored in a variant with the following code:
QObject *object = getObjectFromSomewhere(); QVariant data = QVariant::fromValue(object);
See also QVariant::fromValue().
void qVariantSetValue(QVariant & variant, const T & value)
Sets the contents of the given variant to a copy of the value with the specified template type T.
This function is equivalent to QVariant::setValue(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::setValue().
