A View uses different ViewItem`s to evaluate Querys, Relations or References between MetaClasses per hierarchy level. The result is e.g. displayed in in the View Test Environment.
- Navigate to the Namspace Custom.View.Item's via the Class Browser
- There are three different ViewItem`s
- Create a new instance of a QueryViewItem using the Bulk Editor
- Assign a query instance of the QueryViewItem to the QUERY attribute either by
- Drag and drop a query object onto the cell
- Select the desired Query from the dialog appearing after double-clicking the cell
- Create a new instance of a ReferenceViewItem using the Bulk Editor
- Set the name of the reference property in the REFERENCE cell
- Set the REVERSE checkbox if the ReferenceViewItem should be evaluated from right to left instead of left to right
- Assign a query instance of the ReferenceViewItem to the REVERSEREFTYPE attribute either by
- dragging and dropping a metaclass object onto the cell
- selecting the desired MetaClass from the dialog appearing after double-clicking the cell
- Create a new instance of a RelationViewItem using the Bulk Editor
- Set the REVERSE checkbox if the RelationViewItem should be evaluated from right to left instead of left to right
- Assign a query instance of the RelationViewItem to the RELATION attribute either by
- dragging and dropping a relation object onto the cell
- selecting the desired Relation from the dialog appearing after double-clicking the cell
- Create a new instance of a QueryViewItem using the Bulk Editor
- Set at least name and description
- The required ViewItem's must be added to the view with the Relation Editor.
- Save the changes with Ctrl+S or the save command
