An object in object-oriented programming (OOP) is a data structure that holds values that you can manipulate. Each OpenROAD component—such as a frame, form, or menu item—is an object.

You also can plug external objects into your OpenROAD application. External objects are external controls such as charts, grid controls, HTML controls, and web browsers from independent software vendors.
