Working with RibbonBar – PB Docs 2019

A RibbonBar control enables you to create ribbons which are a modern
way of organizing user commands in user interfaces. A ribbon can replace
the traditional menu bar and toolbars with tabbed pages (called Category);
and each Category splits into Panels that contain individual or groups of
LargeButton (with or without RibbonMenu), SmallButton (with or without
RibbonMenu), CheckBox, ComboBox, TabButton (with or without RibbonMenu),
and Spin (currently unsupported).
