The Class buttons,
, located at the top right of the Class
Relationship pane, allow you to view and edit, create, or delete a class. Note
that these icons have a similar action wherever they appear; for example, see
the Instance Buttons.
The buttons have the following actions:
![]() |
V(iew) button: Click this button to open the Class Form for the highlighted class. This allows you to view or edit the class. See Viewing a Class. |
![]() |
C(reate) button: Click this button to create a new class as a subclass of the highlighted class. See Creating a New Class. |
![]() |
Back-references button: Click this button to view all the objects that reference the highlighted class. See Viewing Back-References. |
![]() |
Delete button: Click this button to delete the highlighted class and all of its subclasses. See Deleting a Class. |
If the Create or Delete button is grayed out, this indicates
that the current class cannot be edited or deleted. Such a class always has a
gray
icon to its left. Classes cannot be edited if they either are a system class or
are included from another project.
