- class PySide6.QtCore.QVersionNumber¶
PySide6.QtCore.QVersionNumber(seg)
PySide6.QtCore.QVersionNumber(seg)
PySide6.QtCore.QVersionNumber(maj)
PySide6.QtCore.QVersionNumber(maj, min)
PySide6.QtCore.QVersionNumber(maj, min, mic)
- Parameters
seg –
maj – int
min – int
mic – int
Produces a null version.

Constructs a QVersionNumber
consisting of just the major version number maj
.
Constructs a QVersionNumber
consisting of the major and minor version numbers maj
and min
, respectively.
Constructs a QVersionNumber
consisting of the major, minor, and micro version numbers maj
, min
and mic
, respectively.
- PySide6.QtCore.QVersionNumber.enum_245¶
- static PySide6.QtCore.QVersionNumber.commonPrefix(v1, v2)¶
- Parameters
- Return type
QVersionNumber
(const QVersionNumber
&v1, const QVersionNumber
&v2)
Returns a version number that is a parent version of both v1
and v2
.
See also
- static PySide6.QtCore.QVersionNumber.compare(v1, v2)¶
- Parameters
- Return type
int
Compares v1
with v2
and returns an integer less than, equal to, or greater than zero, depending on whether v1
is less than, equal to, or greater than v2
, respectively.
Comparisons are performed by comparing the segments of v1
and v2
starting at index 0 and working towards the end of the longer list.
v1 = QVersionNumber(1, 2) v2 = QVersionNumber(1, 2, 0) compare = QVersionNumber.compare(v1, v2) # compare == -1()
- static PySide6.QtCore.QVersionNumber.fromString(string[, suffixIndex=None])¶
- Parameters
string –
QStringView
suffixIndex – int
- Return type
This is an overloaded function.
Constructs a QVersionNumber
from a specially formatted string
of non-negative decimal numbers delimited by ‘.’.
Once the numerical segments have been parsed, the remainder of the string is considered to be the suffix string. The start index of that string will be stored in suffixIndex
if it is not null.
string = QString("5.4.0-alpha") suffixIndex = int() version = QVersionNumber.fromString(string, suffixIndex) # version is 5.4.0 # suffixIndex is 5See also
- static PySide6.QtCore.QVersionNumber.fromString(string)
- Parameters
string – str
- Return type
Constructs a QVersionNumber
from a specially formatted string
of non-negative decimal numbers delimited by a period (.
).
Once the numerical segments have been parsed, the remainder of the string is considered to be the suffix string. The start index of that string will be stored in suffixIndex
if it is not null.
string = QString("5.4.0-alpha") suffixIndex = int() version = QVersionNumber.fromString(string, suffixIndex) # version is 5.4.0 # suffixIndex is 5See also
- PySide6.QtCore.QVersionNumber.isNormalized()¶
- Return type
bool
Returns true
if the version number does not contain any trailing zeros, otherwise returns false
.
See also
- PySide6.QtCore.QVersionNumber.isNull()¶
- Return type
bool
Returns true
if there are zero numerical segments, otherwise returns false
.
See also
- PySide6.QtCore.QVersionNumber.isPrefixOf(other)¶
- Parameters
other –
PySide6.QtCore.QVersionNumber
- Return type
bool
Returns true
if the current version number is contained in the other
version number, otherwise returns false
.
v1 = QVersionNumber(5, 3) v2 = QVersionNumber(5, 3, 1) value = v1.isPrefixOf(v2) # trueSee also
- PySide6.QtCore.QVersionNumber.majorVersion()¶
- Return type
int
Returns the major version number, that is, the first segment. This function is equivalent to segmentAt
(0). If this QVersionNumber
object is null, this function returns 0.
See also
- PySide6.QtCore.QVersionNumber.microVersion()¶
- Return type
int
Returns the micro version number, that is, the third segment. This function is equivalent to segmentAt
(2). If this QVersionNumber
object does not contain a micro number, this function returns 0.
See also
- PySide6.QtCore.QVersionNumber.minorVersion()¶
- Return type
int
Returns the minor version number, that is, the second segment. This function is equivalent to segmentAt
(1). If this QVersionNumber
object does not contain a minor number, this function returns 0.
See also
- PySide6.QtCore.QVersionNumber.normalized()¶
- Return type
Returns an equivalent version number but with all trailing zeros removed.
To check if two numbers are equivalent, use on both version numbers before performing the compare.
v1 = QVersionNumber(5, 4) v2 = QVersionNumber(5, 4, 0) equivalent = v1.normalized() == v2.normalized() equal = v1 == v2 # equivalent is true # equal is false

- PySide6.QtCore.QVersionNumber.segmentAt(index)¶
- Parameters

Returns the segment value at index
. If the index does not exist, returns 0.

- Return type
str
Returns a string with all of the segments delimited by a period (.
).
