I see that you and I are a little confused. I thought this is what you wanted.

class InsetSection {
public:
        void setShortTitle(InsetText const & inset)
        {
                ist_ = inset;
        }

        void drawShortTitle() const
        {
                ist_.draw();
        }
private:
        /** A holder of the short title data. This InsetSection class
             tells it when to draw, hide etc. See InsetCollapsable for an inset
                 that controls how a Button and an InsetText are displayed.
        */
        InsetShortTitle ist_;
};

class InsetShortTitle {
public:
        InsetShortTitle(InsetText const & inset)
        {
                // does whatever it needs to create from InsetText 
                ...
        }
        void draw() const;
}
