QSourceLocation ¶

概要 ¶

详细描述 ¶

QSourceLocation is a simple value based class that has three properties, uri() , line() ，和 column() , that, taken together, identify a certain point in a resource, e.g., a file or an in-memory document.

line() and column() refer to character counts (not byte counts), and they both start from 1, as opposed to 0.

class QSourceLocation ¶

QSourceLocation(other)

QSourceLocation(uri[, line=-1[, column=-1]])

param uri

QUrl

param column

int

param other

QSourceLocation

param line

int

构造 QSourceLocation that doesn’t identify anything at all.

For a default constructed , isNull() 返回 true .

构造 QSourceLocation that is a copy of other .

构造 QSourceLocation with URI u , line l and column c .

PySide2.QtXmlPatterns.QSourceLocation. column ( ) ¶

返回类型

qint64

Returns the current column number. The column number refers to the count of characters, not bytes. The first column is column 1, not 0. The default value is -1, indicating the column number is unknown.

PySide2.QtXmlPatterns.QSourceLocation. isNull ( ) ¶

返回类型

bool

返回 true 若此 QSourceLocation doesn’t identify anything.

For a default constructed QSourceLocation ，此函数返回 true . The same applies for any other QSourceLocation whose uri() is invalid.

PySide2.QtXmlPatterns.QSourceLocation. line ( ) ¶

返回类型

qint64

Returns the current line number. The first line number is 1, not 0. The default value is -1, indicating the line number is unknown.

PySide2.QtXmlPatterns.QSourceLocation. __ne__ ( other ) ¶

参数

other – QSourceLocation

返回类型

bool

返回 true 若此 QSourceLocation is not equal to other ; false 否则。

PySide2.QtXmlPatterns.QSourceLocation. __eq__ ( other ) ¶

参数

other – QSourceLocation

返回类型

bool

返回 true 若此 QSourceLocation 等于 other ; false 否则。

Two QSourceLocation instances are equal if their uri() , line() and column() are equal.

QSourceLocation instances for which isNull() returns true are considered equal.

PySide2.QtXmlPatterns.QSourceLocation. setColumn ( newColumn ) ¶

参数

newColumn – qint64

Sets the column number to newColumn . 0 is an invalid column number. The first column number is 1.
