Detailed Description

Base abstract class for observers registered in ProgressStatus.

Subclasses must redefined virtual functions ChangedValue() and Completed(). User-defined observers must be registered in the progress status object with the help of ProgressStatus.Register().

By default the observer will only be notified in the same thread it was created. This is to minimize a risk of data race in multi-threaded applications if the user-defined observer is not thread-safe. To enable notifications from other threads use SetAllNotifyingThreads() to allow notifications from any thread or different syntaxes of SetNotifyingThread() to enable notifications from single thread.
