How to get layout type from base class?

SPlatten

I am supporting all the layouts by storing an instance of the base class, is there a way to determine the type of layout from the base class?

This is so I know if I can cast the base back to for example QFormLayout to allow use of the form related functions.

You can always try to cast, if the type is wrong you'll get nullptr.

@jsulm , I like that idea:

            QFormLayout* pobjForm(qobject_cast<QFormLayout*>(pobjLayout));
            QGridLayout* pobjGrid(qobject_cast<QGridLayout*>(pobjLayout));
            QHBoxLayout* pobjHBox(qobject_cast<QHBoxLayout*>(pobjLayout));
            QVBoxLayout* pobjVBox(qobject_cast<QVBoxLayout*>(pobjLayout));

Simple and elegant.
