## 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.

### `[noexcept]` QPageRanges::QPageRanges(const QPageRanges &other)

Constructs a QPageRanges object by copying other.

### `[constexpr noexcept default]` QPageRanges::QPageRanges(QPageRanges &&other)

Constructs a QPageRanges object by moving from other.

### `[noexcept]` 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.

### `[noexcept]` QPageRanges &QPageRanges::operator=(QPageRanges &&other)

Moves other into this QPageRanges object.

### `[noexcept]` QPageRanges &QPageRanges::operator=(const QPageRanges &other)

Assigns other to this QPageRanges object.

## Related Non-Members

### 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.
