The Object Tool contains the following fields:

The Name field shows the name of the current object type. This field also has a pop-up menu that allows you to open an existing object type (Open...) or create a new one (New... and New Subtype...).

The read-only Ancestor field shows the type from which the current type is descended: by default, Object.

Each type in a modeling language is stored in a certain project in the repository. By default a newly created object type is stored to the current default project. To store it somewhere else, choose the desired project from the Project pull-down list. Please note that you can only choose from those projects that are currently open. If the project you want is not yet open, you can open it from the MetaEdit+ Launcher (Repository | Open Project...).

The project can be changed as long as the pull-down list remains enabled. As a type must always be defined or loaded from the repository before its subtype, descendants of existing types always belong to the same project as their ancestors: otherwise it would be possible to open a project containing a subtype, without having first loaded its super-type.

The Properties list is described in Section 2.1.3 above.

The Description field shows the textual description of this type. The field should contain the documentation of this type in a form usable as a help text by modeling language users, because this text appears in the help for the modeling language. Basic text formatting (bold etc.) can be applied as in other text fields in MetaEdit+ (see Section 3.3.4 in MetaEdit+ User’s Guide).
