Detailed Description

TValidator forms the base class for several ObjectWindows classes that encapsulate validation objects. The following derived classes make it easy for you to add data validation to your applications.

• TFilterValidator and its derived class, TRangeValidator, check an input field as the user types data into the field in order to determine the validity of the entered data.
• TPXPictureValidator compares user input with a picture of a data format.
• TLookupValidator compares a string typed by a user with a list of acceptable values.

Enumeration Type Documentation

enum owl::TPicResult

Validation result type.

TPicResult is the result type returned by the Picture member function of TPXPictureValidator. The result type indicates whether the data entered into the edit control matches a specified format. For example, prIncomplete indicates that the data entered is missing some information that was specified in the format picture of the data.

enum owl::TValidatorOptions

Validator option flags.

Constants that represent bits in the bitmapped Options word in validator objects.

Enumerator:

voFill	option to fill in chars on IsValidInput checks Used by picture validators to indicate whether to fill in literal characters as the user types.
voTransfer	option to perform conversion & transfer The validator handles data transfer for the input line. Currently only used by range validators.
voOnAppend	option to only validate input on appending Used by picture validators to determine how to interact with edit controls.
voReserved	reserved for future use
