Default Widget Types
The Form Editor displays a widget for each slot in the class. In the Instance Editor, these widgets are displayed as fields where users can enter the information for that slot. The possible display and options for the widget depend on the type of information that is included in the slot. For more information on the different types of slots and fields, see the Instances Table of Contents.
When Protege-Frames generates a default layout, it creates a default widget for each slot. These widgets are described below. Protege-Frames provides widgets for both Single and Multiple cardinality. For simplicity, only the Single cardinality is shown. For a description of the Multiple cardinality widget, see the topic for the corresponding field.
Note: These topics describe the default widgets only. You can select different formats for the widgets using the Widget Type menu.
