Hi there,
I can create a valid QVariant that contains a MyObject pointer with
just the class name (ie, QString("MyObject")) and no access to the
class declaration. MyObject is derived from QObject.
This QVariant has the following properties:
- type() == QVariant::UserType
- userType() == QMetaType::type("MyObject*")
The consumer of this variant, which has access to the original class
declaration, can obtain a valid pointer with
variant.value<MyObject*>()
Now I need to create a QVariant that contains a QList<MyObject*> with
just the class name (ie, QString("MyObject")) and no access to the
class declaration.
Again the resulting variant needs to have the following properties:
- type() == QVariant::UserType
- userType() == QMetaType::type("QList<MyObject*>")
My question is how do I create and "populate" such a variant without
using template involving MyObject*?
QSequentialIterable allows one to iterate on such a variant, but only
provide a const access, so it is useless in my case.
I seem to have found a solution, but i'm not sure it is correct and safe:
QList<QObject*> list;
// populate the list with MyObject* items
int desiredMetaTypeId = QMetaType::type("QList<MyObject*>")
return QVariant(desiredMetaTypeId, &list);
Does anyone know a "proper" solution for this? Or is my approach
correct and safe?
Thanks in advance,
Chris
