This validator checks whether user input is a double in the pre-defined range.


Member Function Documentation

double Wt::WDoubleValidator::bottom (  )  const [inline]

Return the bottom of the valid double range.

The default value is -stdnumeric_limits<int>::max().

void Wt::WDoubleValidator::setTop ( double  top  ) 

Set the top of the valid double range.

The default value is std::numeric_limits<int>::max().

WValidator::State Wt::WDoubleValidator::validate ( WString input,
int &  pos 
) const [virtual]

Validate the given input.

The input is considered valid only when it is blank for a non-mandatory field, or represents a double within the valid range.

Reimplemented from Wt::WValidator.

void Wt::WDoubleValidator::setInvalidNotANumberText ( const WString text  ) 

Set the message to display when the input is not a number.

The default value is "Must be a number."

WString Wt::WDoubleValidator::invalidNotANumberText (  )  const

Returns the message displayed when the input is not a number.

See also:
setInvalidNotANumberText(const WString&)

void Wt::WDoubleValidator::setInvalidTooSmallText ( const WString text  ) 

Set message to display when the number is too small.

Depending on whether bottom() and top() are real bounds, the default message is "The number must be between {1} and {2}" or "The number must be larger than {1}".

WString Wt::WDoubleValidator::invalidTooSmallText (  )  const

Returns the message displayed when the number is too small.

See also:
setInvalidTooSmallText(const WString&)

void Wt::WDoubleValidator::setInvalidTooLargeText ( const WString text  ) 

Set message to display when the number is too large.

Depending on whether bottom() and top() are real bounds, the default message is "The number must be between {1} and {2}" or "The number must be smaller than {2}".

WString Wt::WDoubleValidator::invalidTooLargeText (  )  const

Returns the message displayed when the number is too large.

See also:
setInvalidTooLargeText(const WString&)

std::string Wt::WDoubleValidator::javaScriptValidate ( const std::string &  jsRef  )  const [protected, virtual]

Creates a Javascript expression that validates the input.

The JavaScript expression should evaluate to an object with two fields: a boolean valid, and a message that indicates the problem if not valid.

Return an empty string if you are not provide the client-side validation.
