SetLogFinger

Sets the log finger to a particular Cyberdog item.

void SetLogFinger (in CyberItem item);

item

A CyberItem object representing a location just visited by the user.

DISCUSSION

This method sets the log finger to point to the Cyberdog item that the user visited most recently. Your Cyberdog display part should call this method when its window acquires the selection focus or, more generally, when your part determines that the Cyberdog item whose referenced content it displays is the current item.

This method assumes that the Cyberdog item has already been added to the log; if the item is not in the log, this method does nothing. Typically, you call this method after adding a Cyberdog item to the log (AddCyberItemToLog) or determining that a Cyberdog item is already in the log (LogContainsCyberItem).

Do not subclass this class.
