Detailed Description
QueryCtrl allows a query to be cancelled.
Constructor & Destructor Documentation
  | 
virtual | 
Destroys a QueryCtrl.
Letting a QueryCtrl go out of scope has no effect on the query, that is, the destructor does not implicitly call cancel().

Cancels an executing query.
Calling cancel() informs the scope to which a query was sent that the query should be cancelled. Calling cancel() on a query that is complete has no effect. cancel() is guaranteed to not block the caller.
