PrF UG inst instance icons
The Instance Icons
The icons in the Instances Browser give information about the instances.
These icons give information about a slot. When a class inherits a class from a superclass, icons in the Template Slots pane give information related to the inheritance and overrides; these icons are not shown anywhere else.
A solid icon means that the instance is part of this project.
A pale icon indicates an instance that has been included from another project. These instances cannot be edited.
