  1. to transfer data from a C++ variable or own storage to and from a control; -
  2. to validate data in a control, and show an appropriate error message; -
  3. to filter events (such as keystrokes), thereby changing the behaviour of the associated control. -

Validators can be plugged into controls dynamically. - - -""" - - - -if __name__ == '__main__': - import sys,os - import run - run.main(['', os.path.basename(sys.argv[0])] + sys.argv[1:]) -
