Are widget pools static or dynamic objects?

It may strike you as you read through this discussion that there is a bit of an inconsistency in how Progress manages widget pools as opposed to other kinds of objects. A widget pool seems to be a dynamic object in its own right, but it doesn’t have a handle. You use a CREATE statement to create a pool and a DELETE statement to get rid of it, but you reference it only by name and never by a handle. This is a valid observation, and one that you simply need to accept. A widget pool is definitely a dynamic object. It is created only when the CREATE statement is executed, just like other dynamic objects. It has no definition that the compiler is aware of as true static objects do. But it is true that you refer to it by name and not by a handle.
