Detailed Description

Describes the size, orientation and margins of a page. The QPageLayout class defines the layout of a page in a paged document, with the page size, orientation and margins able to be set and the full page and paintable page rectangles defined by those attributes able to be queried in a variety of units.

The page size is defined by the QPageSize class which can be queried for page size attributes. Note that the QPageSize itself is always defined in a Portrait orientation.

The minimum margins can be defined for the layout but normally default to 0. When used in conjunction with printing support the minimum margins will reflect the minimum printable area defined by the printer.

In the default StandardMode the current margins and minimum margins are always taken into account. The paintable rectangle is the full page rectangle less the current margins, and the current margins can only be set to values between the minimum margins and the maximum margins allowed by the full page size.

In FullPageMode the current margins and minimum margins are not taken into account. The paintable rectangle is the full page rectangle, and the current margins can be set to any values regardless of the minimum margins and page size.

Member Enumeration Documentation

enum QPageLayout::Mode

Defines the page layout mode.

Constant	Value	Description
`QPageLayout::StandardMode`	`0`	Paint rectangle includes margins, margins must fall between the minimum and maximum
`QPageLayout::FullPageMode`	`1`	Paint rectangle excludes margins, margins can be any value and must be managed manually

enum QPageLayout::Orientation

This enum type is used to specify each page's orientation. This type interacts with QPrinter::PaperSize and QPrinter::setFullPage() to determine the final size of the page available to the application.

Constant	Value	Description
`QPageLayout::Portrait`	`0`	Page height is greater than width
`QPageLayout::Landscape`	`1`	Page width is greater than height

Constructor & Destructor Documentation

QPageLayout::QPageLayout ( )

Creates an invalid QPageLayout.

QPageLayout::QPageLayout	(	const QPageSize &	pageSize,
		Orientation	orientation,
		const QMarginsF &	margins,
		Unit	units = `QPageSize::Unit::Point`,
		const QMarginsF &	minMargins = `QMarginsF(0, 0, 0, 0)`
	)

Creates a QPageLayout with the given pageSize, orientation and margins in the given units. The constructed QPageLayout will be in StandardMode.

Optionally the minimum allowed margins minMargins can be defined. These are the minimum margins supported by the physical print device. The margins given will be clamped to the minimum margins and the maximum margins allowed by the page size.

QPageLayout::QPageLayout ( const QPageLayout & other )

Copy constructs a new QPageLayout from other.

QPageLayout::~QPageLayout ( )

Destroys the page layout.

QMarginsF QPageLayout::maximumMargins ( ) const

Returns the maximum margins that would be applied if the page layout was in StandardMode.

The maximum margins allowed are calculated as the full size of the page minus the minimum margins set. For example, if the page width is 100 points and the minimum right margin is 10 points, then the maximum left margin will be 90 points.

See also: setMinimumMargins(), minimumMargins()

QMarginsF QPageLayout::minimumMargins ( ) const

Orientation QPageLayout::orientation ( ) const

Returns the page orientation of the page layout.

See also: setOrientation()

QPageSize QPageLayout::pageSize ( ) const

Returns the page size of the page layout.

Note that the QPageSize is always defined in a Portrait orientation. To obtain a size that takes the set orientation into account you must use fullRect().

See also: setPageSize()

QRectF QPageLayout::paintRect ( ) const

Returns the page rectangle in the current layout units.

The paintable rectangle takes into account the page size, orientation and margins.

If the FullPageMode mode is set then the fullRect() is returned and the margins must be manually managed.

QRectF QPageLayout::paintRect ( Unit units ) const

Returns the page rectangle in the required units.

The paintable rectangle takes into account the page size, orientation and margins. If the FullPageMode mode is set then the fullRect() is returned and the margins must be manually managed.

QRect QPageLayout::paintRectPixels ( int resolution ) const

Returns the paintable rectangle in rounded device pixels for the given resolution.
