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.

注意： 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.

注意： 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

返迴 true if the ranges include the page pageNumber ；否則返迴 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 對象。

另請參閱 isEmpty ().

bool QPageRanges:: isEmpty () const

返迴 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 )

賦值 other 到此 QPageRanges 對象。

QPageRanges &QPageRanges:: operator= ( QPageRanges && other )

移動 other 到此 QPageRanges 對象。
