The EditCheckClass creates a CHECK control, accepts input from the end user, then returns the input to the variable specified by the Init method, typically the variable associated with a specific LIST cell'a field in the LIST control's data source QUEUE. The EditCheckClass also signals the calling procedure whenever significant edit-in-place events occur, such as tabbing to a new column, cancelling the edit, or completing the edit (moving to a new record or row). The EditCheckClass provides a virtual TakeEvent method to let you take control of significant edit-in-place events.
