The class buttons

located at the top right of the Class Browser, allow you to view and edit, view references to, create, or delete a class.

The buttons have the following actions:

• The View Class button (

  Error creating thumbnail: Unable to save thumbnail to destination
  )

     opens the Class Editor
     for the highlighted class.
     This allows you to view
     or edit the class.
  

• The View References to Class button (

  Error creating thumbnail: Unable to save thumbnail to destination
  )

     opens the References Window,
     which shows all the frames that reference the highlighted class.
     See Viewing References.
  

• The Create Class button (

  Error creating thumbnail: Unable to save thumbnail to destination
  )

     creates a new class
     as a subclass of the highlighted class.
  

• The Delete Class button (

  Error creating thumbnail: Unable to save thumbnail to destination
  )

     deletes
     the highlighted class and all of its subclasses.
  

If the Create Class or Delete Class button is grayed out, this indicates that the current class cannot be edited or deleted. A non-editable class always has a pale class icon to its left. A class cannot be edited if it is a system class or if it is included from another project.

Additional Buttons

The buttons above have the same operation wherever they appear. Additional buttons in the Protege-Frames interface allow you to add and remove the classes specified in a slot, field, or other relationship.

• The Add Class button (

  Error creating thumbnail: Unable to save thumbnail to destination
  )

     displays a dialog box that allows you
     to select one or more existing classes.
  

• The Remove Class button (

  Error creating thumbnail: Unable to save thumbnail to destination
  )

     removes the class from the current relationship
     without deleting it from the knowledge base.
