- //! This widget implements a collapsable group with a configurable framerate
- /*! This class is a group with a button 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 dynamically collapsable group similar to those available in
- other GUI toolkits.
- The callback is invoked whenever the button is pressed to open/close the group.
