PySide2.QtCore.QVersionNumber.enum_271
static PySide2.QtCore.QVersionNumber.commonPrefix(v1, v2)
Parameters
Return type

QVersionNumber

QVersionNumber (const QVersionNumber &v1, const QVersionNumber &v2)

Returns a version number that is a parent version of both v1 and v2 .

isPrefixOf()

static PySide2.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.

QVersionNumber v1(1, 2);
QVersionNumber v2(1, 2, 0);
int compare = QVersionNumber::compare(v1, v2); // compare == -1
static PySide2.QtCore.QVersionNumber.fromString(string)
Parameters

string – unicode

Return type

QVersionNumber

PySide2.QtCore.QVersionNumber.isNormalized()
Return type

bool

Returns true if the version number does not contain any trailing zeros, otherwise returns false .

normalized()

PySide2.QtCore.QVersionNumber.isNull()
Return type

bool

Returns true if there are zero numerical segments, otherwise returns false .

segments()

PySide2.QtCore.QVersionNumber.isPrefixOf(other)
Parameters

otherQVersionNumber

Return type

bool

Returns true if the current version number is contained in the other version number, otherwise returns false .

QVersionNumber v1(5, 3);
QVersionNumber v2(5, 3, 1);
bool value = v1.isPrefixOf(v2); // true

PySide2.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.

PySide2.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.

PySide2.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.

PySide2.QtCore.QVersionNumber.normalized()
Return type

QVersionNumber

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.

QVersionNumber v1(5, 4);
QVersionNumber v2(5, 4, 0);
bool equivalent = v1.normalized() == v2.normalized();
bool equal = v1 == v2;
// equivalent is true
// equal is false
