Detailed Description

provides a view for displaying relations between database tables.

It is currently used for two purposes:

  • displaying global database relations
  • displaying relations defined for a database query

The class is for displaying only - retrieving data and updating data on the backend side is implemented in KexiRelationWidget, and more specifically in: Kexi Relation Part and Kexi Query Part.
