Detailed Description¶

Use pageRanges() to access the collection of page ranges associated with a paged device.

__init__()¶

Constructs an empty QPageRanges object.

__init__(other)

Parameters:: other – QPageRanges

Constructs a QPageRanges object by copying other.

addPage(pageNumber)¶

Parameters:: pageNumber – int

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.

Parameters:

from – int
to – int

firstPage()¶

Return type:: int

Returns the index of the first page covered by the page ranges, or 0 if the page ranges are empty.

static fromString(ranges)¶

Parameters:: ranges – str
Return type:: QPageRanges

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);
