TWideStrings.SetUpdateState Method

Performs internal adjustments before or after a series of updates.

Pascal
procedure SetUpdateState(Updating: Boolean); virtual;
C++
virtual __fastcall SetUpdateState(Boolean Updating);
Description

SetUpdateState is called at the beginning or end of a series of updates. When the BeginUpdate method is first called and the TWideStrings object is not already in the middle of an update, TWideStrings calls SetUpdateState internally, with Updating set to true. When the EndUpdate method is called and it cancels out the last unmatched call to BeginUpdate, TWideStrings calls SetUpdateState internally, with Updating set to false. 

As implemented in TWideStrings, SetUpdateState does nothing. Descendant classes can override this method to optimize the response to updates.
