Inheritance diagram for owl::TLookupValidator:

Public Member Functions
	TLookupValidator ()
	Constructs a TLookupValidator object.

bool	IsValid (LPCTSTR str)
	IsValid overrides TValidator's virtual function and calls Lookup to find the string str in the list of valid input items.

virtual bool	Lookup (LPCTSTR str)
	Searches for the string str in the list of valid entries and returns true if it finds str; otherwise, returns false.

Public Member Functions inherited from owl::TValidator
	TValidator ()
	Constructs an abstract validator object and sets Options fields to 0.

virtual	~TValidator ()
	Destroys an abstract validator object.

virtual void	Error (TWindow *owner)
	Error is an abstract function called by Valid when it detects that the user has entered invalid information.

virtual bool	IsValidInput (TCHAR *input, bool suppressFill)
	Checks current input against validator.

virtual uint	Transfer (TCHAR text, void buffer, TTransferDirection direction)
	Allows a validator to set and read the values of its associated edit control.

virtual int	Adjust (tstring &text, int &begPos, int &endPos, int amount)
	Adjusts the 'value' of the text, given a cursor position and an amount.

bool	Valid (LPCTSTR str, TWindow *owner=0)
	Returns true if IsValid returns true.

bool	Valid (const tstring &str, TWindow *owner=0)

bool	HasOption (int option)
	Gets the Options bits. Returns true if a specified option is set.

void	SetOption (int option)
	Sets the bits for the Options data member.

void	UnsetOption (int option)
	Unsets the bits specified in the Options data member.

Detailed Description

A streamable class, TLookupValidator compares the string typed by a user with a list of acceptable values.

TLookupValidator is an abstract validator type from which you can derive useful lookup validators. You will never create an instance of TLookupValidator. When you create a lookup validator type, you need to specify a list of valid items and override the Lookup method to return true only if the user input matches an item in that list. One example of a working descendant of TLookupValidator is TStringLookupValidator.

Constructor & Destructor Documentation

◆ TLookupValidator()

owl::TLookupValidator::TLookupValidator ( )

Constructs a TLookupValidator object.

Member Function Documentation

◆ IsValid()

bool owl::TLookupValidator::IsValid ( LPCTSTR str )

virtual

IsValid overrides TValidator's virtual function and calls Lookup to find the string str in the list of valid input items.

IsValid returns true if Lookup returns true, meaning Lookup found str in its list; otherwise, it returns false.

Reimplemented from owl::TValidator.

Definition at line 35 of file lookval.cpp.

References Lookup().

◆ Lookup()

bool owl::TLookupValidator::Lookup ( LPCTSTR str )

virtual

Searches for the string str in the list of valid entries and returns true if it finds str; otherwise, returns false.

TLookupValidator's Lookup is an abstract method that always returns false. Descendant lookup validator types must override Lookup to perform a search based on the actual list of acceptable items.

Reimplemented in owl::TStringLookupValidator.
