SYNOPSIS

       Inherits QValidator.

       QIntValidator ( QObject * parent, const char * name = 0 )
       QIntValidator ( int minimum, int maximum, QObject * parent, const char * name = 0 )
       ~QIntValidator ()
       virtual QValidator::State validate ( QString & input, int & ) const
       void setBottom ( int )
       void setTop ( int )
       virtual void setRange ( int bottom, int top )
       int bottom () const
       int top () const

   Properties
       int bottom - the validator's lowest acceptable value
       int top - the validator's highest acceptable value

DESCRIPTION

       The QIntValidator class provides a validator which ensures that a string contains a valid integer within a specified range.

       Example of use:

	   QValidator* validator = new QIntValidator( 100, 999, this );
	   QLineEdit* edit = new QLineEdit( this );
	   // the edit lineedit will only accept integers between 100 and 999
	   edit->setValidator( validator );

       Below we present some examples of validators. In practice they would normally be associated with a widget as in the example above.

	   QString str;
	   int pos = 0;
	   QIntValidator v( 100, 999, this );
	   str = "1";
	   v.validate( str, pos );     // returns Intermediate
	   str = "12";
	   v.validate( str, pos );     // returns Intermediate
	   str = "123";
	   v.validate( str, pos );     // returns Acceptable
	   str = "678";
	   v.validate( str, pos );     // returns Acceptable
	   str = "1234";
	   v.validate( str, pos );     // returns Invalid
	   str = "-123";
	   v.validate( str, pos );     // returns Invalid
	   str = "abc";
	   v.validate( str, pos );     // returns Invalid
	   str = "12cm";
	   v.validate( str, pos );     // returns Invalid

       The minimum and maximum values are set in one call with setRange() or individually with setBottom() and setTop().

MEMBER FUNCTION DOCUMENTATION

QIntValidator::QIntValidator ( QObject * parent, const char * name = 0 )
       Constructs a validator called name with parent parent, that accepts all integers.

QIntValidator::QIntValidator ( int minimum, int maximum, QObject * parent, const char * name = 0 )
       Constructs a validator called name with parent parent, that accepts integers from minimum to maximum inclusive.

QIntValidator::~QIntValidator ()
       Destroys the validator, freeing any resources allocated.

int QIntValidator::bottom () const
       Returns the validator's lowest acceptable value. See the "bottom" property for details.

void QIntValidator::setBottom ( int )
       Sets the validator's lowest acceptable value. See the "bottom" property for details.

void QIntValidator::setRange ( int bottom, int top ) [virtual]
       Sets the range of the validator to only accept integers between bottom and top inclusive.

void QIntValidator::setTop ( int )
       Sets the validator's highest acceptable value. See the "top" property for details.

int QIntValidator::top () const
       Returns the validator's highest acceptable value. See the "top" property for details.

QValidator::State QIntValidator::validate ( QString & input, int & ) const [virtual]
       Returns Acceptable if the input is an integer within the valid range, Intermediate if the input is an integer outside the valid range and
       Invalid if the input is not an integer.

       Note: If the valid range consists of just positive integers (e.g. 32 - 100) and input is a negative integer then Invalid is returned.

	   int pos = 0;
	   s = "abc";
	   v.validate( s, pos ); // returns Invalid
	   s = "5";
	   v.validate( s, pos ); // returns Intermediate
	   s = "50";
	   v.validate( s, pos ); // returns Valid

       Reimplemented from QValidator.

   Property Documentation
int bottom
       This property holds the validator's lowest acceptable value.

       Set this property's value with setBottom() and get this property's value with bottom().

       See also setRange().

int top
       This property holds the validator's highest acceptable value.

       Set this property's value with setTop() and get this property's value with top().

       See also setRange().
