Declaration and documentation text for this Property |
Notice that other Data objects (XFolders and XObjects) can be declared as data types. This allows a single Property to control the whole functionality of an object, so that library maintenance becomes easier.
Editing this object has the same graphical resources and options available for Screen edition. Users can insert XControls on any Screen or even inside another XControl by right-clicking a destination Screen or XControl and then selecting the Insert option.
From this moment on, this XControl contains a name inside a Screen, and it is considered a copy of its original definition. Thus, users can define, if needed, values or Links that this specific copy has in the context it is used.
