Detailed Description

Base class for Viewable Objects.

Data objects can have callback functions that are fired when their value is changed. Data parents can also be notified when data value are modified by using the UOn::dataChange condition (see below).

see an example in class UStr. The only difference is that UOn::dataChange must be used instead of UOn::strChange for specifing callbacks in parents.
