The Extended Widgets subsystem uses a pool dictionary called EwConstants to provide pool variables for constant values that are used as arguments to Extended Widgets methods. These pool variable names should be used instead of directly using their constant values. Classes that require pool variable names must include the EwConstants pool dictionary in their class definition.

Many constants are also defined in the CwConstants pool dictionary. The CwConstants pool dictionary should also be included in the class definition of classes that require these pool variable names.
