Detailed Description#
Warning
This section contains snippets that were automatically translated from C++ to Python and may contain errors.
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.
str = QString() 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 from being 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.
Note
The QLocale::NumberOptions set on the locale() also affect the way the number is interpreted. For example, since QLocale::RejectGroupSeparator is not set by default, the validator will accept group separators. It is thus recommended to use QLocale::toInt() to obtain the numeric value.

- class PySide6.QtGui.QIntValidator([parent=None])#
PySide6.QtGui.QIntValidator(bottom, top[, parent=None])
- Parameters:
bottom – int
top – int
parent –
PySide6.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.
Note
Properties can be used directly when from __feature__ import true_property is used or via accessor functions otherwise.
- property PᅟySide6.QtGui.QIntValidator.bottom: int#
This property holds the validator’s lowest acceptable value.
By default, this property’s value is derived from the lowest signed integer available (-2147483648).

- property PᅟySide6.QtGui.QIntValidator.top: int#
This property holds the validator’s highest acceptable value.
By default, this property’s value is derived from the highest signed integer available (2147483647).
