TakeKey, DERIVED
The TakeKey method processes an alerted keystroke for the LIST control and returns a value indicating whether the browse list display must change.
By default, all alphanumeric keys are alerted for LIST controls.
Implementation:
The TakeKey method primes the FreeElement property with the appropriate search value, then returns one (1) if a new search is required or returns zero (0) if no new search is required. A search is required only if the keystroke is a valid search character.
Return Data Type: BYTE
Example:
IF SELF.Sort.Locator.TakeKey() !process the search key
SELF.Reset(1) ! if valid, reset the view
SELF.ResetQueue( Reset:Done ) ! and the browse queue
END
