Detailed Description

The QIntValidator class provides a validator that ensures 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, 900, this);

str = "1";

v.validate(str, pos); // returns Intermediate

str = "012";

v.validate(str, pos); // returns Intermediate

str = "123";

v.validate(str, pos); // returns Acceptable

str = "678";

v.validate(str, pos); // returns Acceptable

str = "999";

v.validate(str, pos); // returns Intermediate

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

Notice that the value 999 returns Intermediate. Values consisting of a number of digits equal to or less than the max value are considered intermediate. This is intended because the digit that prevents a number to be in range is not necessarily the last digit typed. This also means that an intermediate number can have leading zeros.

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

QIntValidator uses its locale() to interpret the number. For example, in Arabic locales, QIntValidator will accept Arabic digits. In addition, QIntValidator is always guaranteed to accept a number formatted according to the "C" locale.

Constructor & Destructor Documentation

QtGui.QIntValidator.QIntValidator ( System.Type  dummy)
protected
QtGui.QIntValidator.QIntValidator ( QObject  parent = null)

Constructs a validator with a parent object that accepts all integers.

QtGui.QIntValidator.QIntValidator ( int  bottom,
int  top,
QObject  parent = null 
)

Constructs a validator with a parent, that accepts integers from minimum to maximum inclusive.

Sets the range of the validator to only accept integers between bottom and top inclusive.

string  c,
int  n 
)
static
override QValidator.State QtGui.QIntValidator.Validate ( string  input,
ref int  pos 
)
virtual

Reimplemented from QValidator::validate().

Returns Acceptable if the input is an integer within the valid range, Intermediate if the input is a prefix of an integer in the valid range, and Invalid otherwise.

If the valid range consists of just positive integers (e.g., 32 to 100) and input is a negative integer, then Invalid is returned. (On the other hand, if the range consists of negative integers (e.g., -100 to -32) and input is a positive integer, then Intermediate is returned, because the user might be just about to type the minus (especially for right-to-left languages).

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 Acceptable

By default, the pos parameter is not used by this validator.

Implements QtGui.QValidator.

Property Documentation

new int QtGui.QIntValidator.Bottom
getset

This property holds the validator's lowest acceptable value.

By default, this property's value is derived from the lowest signed integer available (typically -2147483647).

new IQIntValidatorSignals QtGui.QIntValidator.Emit
getprotected
new QMetaObject QtGui.QIntValidator.StaticMetaObject
staticget
new int QtGui.QIntValidator.Top
getset

This property holds the validator's highest acceptable value.

By default, this property's value is derived from the highest signed integer available (typically 2147483647).
