Using the Type Library Editor

Go Up to Working with Type Libraries Index

Using the type library editor, you can create new type libraries or edit existing ones. Typically, an application developer uses a wizard to create the objects that are exposed in the type library, letting Delphi generate the type library automatically. Then, the automatically generated type library is opened in the Type Library editor so that the interfaces can be defined (or modified), type definitions added, and so on.

However, even if you are not using a wizard to define the objects, you can use the Type Library editor to define a new type library. In this case, you must create any implementation classes yourself, because the Type Library editor does not generate code for CoClasses that were not associated with a type library by a wizard.

The editor supports a subset of Valid Types in a type library.
