QVariant backward conversion. How?

[bogong]

Hello all!
I have QVariantList and I need to convert every element of this list to the pure Qt data type from QVariant automatically. Kind of backward convesion to original type from QVariant. Something like this:

if (element.isInt()) {
   ...
}
if (element.isQString()) {
   ...
}
if (element.isAnyQVariant()) {
   ...
}
...

Not casting. Casting is statically defining type. I need dynamical function. I need kind of "isType" function. Is there any?

You can do if (element.type() == qMetaTypeId<SomeType>()) { ... }.

edit sorry my bad @bogong you can can't use https://doc.qt.io/qt-5/qvariant.html#canConvert

@LeLev canConvert is not exactly useful for detecting type. It will, for example, happily return true for converting int to QString.
