The Properties tab uses a tree structure to display the subjects, metaclasses, and properties.
In the left column, the subjects are listed in boldface font; expand the plus sign to view the metaclasses for a particular subject. When you expand a metaclass, the corresponding properties are listed in the left column, with their current values (if any) listed in the right column.
Items are typically in alphabetic order; however, metaclasses that are of the same type as the context are "pushed up" to be first. For example, if you are viewing the properties of a selected class, the first metaclass displayed is CG::Class.
In general, a subject is displayed for an element if it contains a metaclass that matches the metaclass of the element. The following table lists the exceptions to this rule.
| Subjects Visible Only Under the Project | Subjects Visible Under Diagrams and the Project | Subjects Visible Under Only the Configuration/Component and the Project |
|---|---|---|
Selecting a property displays the definition for the property in the bottom pane of the window. Each time a new property is selected, the definition is updated in the bottom pane. Definitions are displayed for all three of the property levels: subject, metaclass, and the individual property.
