Paired User Interface Object

This operator is loaded simultaneously with a user interface object. The user interface object can be moved to another page, and would normally be displayed in the end-user application. The operator and this user interface object can never be separated. If you delete the operator, the user interface is deleted automatically as well. Note that you cannot delete the user interface, only the operator symbol!

This viewer will only show the real part of an input vector.

User Interface Object on Printable Pages

The user interface of this component will be printed on a report, if it is put on a Printable Page (see "Page").

This means that if this object has the same SyncID as the object that changes the Data Cursor, then this object will change its state accordingly.
