Detailed Description
Use QPagedPaintDevice::pageRanges() to access the collection of page ranges associated with a paged device.
Member Function Documentation
QPageRanges::QPageRanges()
Constructs an empty QPageRanges object.
QPageRanges::QPageRanges(const QPageRanges &other)
Constructs a QPageRanges object by copying other.
QPageRanges::QPageRanges(QPageRanges &&other)
Constructs a QPageRanges object by moving from other.
QPageRanges::~QPageRanges()
Destroys the page ranges.
void QPageRanges::addPage(int pageNumber)
Adds the single page pageNumber to the ranges.
Note: Page numbers start with 1. Attempts to add page numbers smaller than 1 will be ignored with a warning.
void QPageRanges::addRange(int from, int to)
Adds the range specified with from and to to the ranges.
Note: Page numbers start with 1. Attempts to add page numbers smaller than 1 will be ignored with a warning.
void QPageRanges::clear()
Removes all page ranges.
bool QPageRanges::contains(int pageNumber) const
Returns true if the ranges include the page pageNumber; otherwise returns false.
int QPageRanges::firstPage() const
Returns the index of the first page covered by the page ranges, or 0 if the page ranges are empty.
[static] QPageRanges QPageRanges::fromString(const QString &ranges)
Constructs and returns a QPageRanges object populated with the ranges from the string representation.
QPrinter printer; QPageRanges ranges = QPageRanges::fromString("1-3,6-7"); printer.setPageRanges(ranges);
In case of parsing error, returns an empty QPageRanges object.
See also isEmpty().
bool QPageRanges::isEmpty() const
Returns true if the ranges are empty; otherwise returns false.
int QPageRanges::lastPage() const
Returns the index of the last page covered by the page ranges, or 0 if the page ranges are empty.
QList<QPageRanges::Range> QPageRanges::toRangeList() const
Returns a list with the values of the ranges.
QString QPageRanges::toString() const
Returns the string representation of the page ranges.
QPageRanges &QPageRanges::operator=(const QPageRanges &other)
Assigns other to this QPageRanges object.
QPageRanges &QPageRanges::operator=(QPageRanges &&other)
Moves other into this QPageRanges object.

QDataStream &operator<<(QDataStream &stream, const QPageRanges &pageRanges)
Writes pageRanges to stream as a range string.
See also QPageRanges::toString.
QDataStream &operator>>(QDataStream &stream, QPageRanges &pageRanges)
Reads a page ranges string from stream and stores it in pageRanges.
See also QPageRanges::fromString.
