- //! This class provides an alternative to Fl_Group that automatically arranges the children either left to right and top to bottom (for type() == c FL_VERTICAL), or top to bottom and left to right (for type() == c FL_HORIZONTAL), within the available size of the group, with a scrollbar turning on if they don't all fit
- /*! This class is a group with a scrollbar and an b Fl_Group inside (both publicly exposed). The b Fl_Group
- contains the actual child widgets of this group.
- Most of the b Fl_Group member functions are reimplemented here in a pass-through fashion to the
- internal group. This means that casual use of a descendent instance will be almost exactly the same
- as for a regular b Fl_Group, with any additional access provided directly through member b group.
- The goal of this class is to provide a group that dynamically and evenly distributes its children within
- a fixed space, similar to those available in other GUI toolkits.
