Summary

Responds when Count or Items changes.

Pascal

 procedureChanged;

Description

Changed is called automatically when Items change or when the EndUpdate method signals that an update is complete. It checks the value of UpdateCount, and if it is 0, calls the UpdateAll method, which performs any necessary updates.
When writing a viewer descendant, there is no need to call Changed. Instead, bracket any changes by calls to BeginUpdate and EndUpdate.
