Detailed Description

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

Example of use:

validator = QIntValidator(100, 999, self)
edit = QLineEdit(self)

# 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.

pos = 0
v = QIntValidator(100, 900, self)

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 PySide.QtGui.QIntValidator.setRange() , or individually with PySide.QtGui.QIntValidator.setBottom() and PySide.QtGui.QIntValidator.setTop() .

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

class PySide.QtGui.QIntValidator([parent=None])

class PySide.QtGui.QIntValidator(bottom, top[, parent=None])

Parameters:

• bottom – PySide.QtCore.int
• parent – PySide.QtCore.QObject

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

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

PySide.QtGui.QIntValidator.bottom()

Return type:PySide.QtCore.int

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).
