Flexible graphic element objects in a process plant are configurable both in a run-time operating environment in which a process is being controlled and in a configuration environment. An instantiated flexible graphic element object may be a display view or may be another graphic element included on a display view. A graphic element object may be linked to and/or derived from another graphic element object, and changes to a particular graphic element object may be propagated to its derivations, e.g., according to a distribution policy. Changes to definitions corresponding to a particular graphic element object (e.g., to the definition of a graphic element attribute such as a shape, animation, event handler or property) may be overridden or modified in another object derived from the particular graphic element object. The modified derived object may be renamed and saved separately from the particular graphic element object. |
