Doubts about breaking Model View separation

[user13]

If i have a Model like the following

class Model : public QAbstractListModel {
private:
  QList<Base*> _data;
public:
  //virtual functions of the base class : insertRow(), data(), etc...

  void insertObject(Base* ptr) { _data.push_back(ptr) };
};

where Base is the base class of a hierarchy :

class Base {};
class Derived1 : public Base {};
class Derived2 : public Base {};

Is it possible to call Derived1 constructor in a slot of a QWidget to create a new object to insert in model::_data?
Any help would be highly appreciated!

Link to the repo with a working example (see AddDialog class)

Sure, why not?
What is the problem?

Thank you for the reply!
I was doubtful since I tought that a call to the constructor of an object, which is "managed" by the Model, from a slot in a QWidget would "break" the separation between Model and View.
