Depending on the current view style, the control display different types of {{UBIK}} classes. Each major class type is by default associated with an unique icon, in order to provide a visual distinction of the class types. However, these icons can be replaced by more specific ones during the customization process, which means that it is not a reliable indicator if an object is of a certain type.
The coloring of an icon indicates another object status: if the icon appears grey instead of its regular coloring, the respective object is considered as a [[System Objectobjects| system object]].
A blue triangle in the upper left corner of an icon indicates that the object is an instance of another object in the same view.
