QPageLayout::QPageLayout()

Creates an invalid QPageLayout.

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

Creates a QPageLayout with the given pageSize, orientation and margins in the given units.

Optionally define the minimum allowed margins minMargins, e.g. the minimum margins able to be printed by a physical print device.

The constructed QPageLayout will be in StandardMode.

The margins given will be clamped to the minimum margins and the maximum margins allowed by the page size.

Copy constructor, copies other to this.

QPageLayout::~QPageLayout()

Destroys the page layout.

QRectF QPageLayout::fullRect() const

Returns the full page rectangle in the current layout units.

The page rectangle takes into account the page size and page orientation, but not the page margins.

See also paintRect() and units().

QRectF QPageLayout::fullRect(QPageLayout::Unit units) const

Returns the full page rectangle in the required units.

The page rectangle takes into account the page size and page orientation, but not the page margins.

See also paintRect().

QRect QPageLayout::fullRectPixels(int resolution) const

Returns the full page rectangle in device pixels for the given resolution.

The page rectangle takes into account the page size and page orientation, but not the page margins.

See also paintRect().

QRect QPageLayout::fullRectPoints() const

Returns the full page rectangle in Postscript Points (1/72 of an inch).

bool QPageLayout::isEquivalentTo(const QPageLayout &other) const

Returns true if this page layout is equivalent to the other page layout, i.e. if the page has the same size, margins and orientation.

bool QPageLayout::isValid() const

Returns true if this page layout is valid.

QMarginsF QPageLayout::margins() const

Returns the margins of the page layout using the currently set units.

QMargins QPageLayout::marginsPoints() const

Returns the margins of the page layout in Postscript Points (1/72 of an inch).

See also setMargins() and margins().

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() and minimumMargins().

QMarginsF QPageLayout::minimumMargins() const

Returns the minimum margins of the page layout.

See also setMinimumMargins() and maximumMargins().

QPageLayout::Mode QPageLayout::mode() const

Returns the page layout mode.

See also setMode().

QPageLayout::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(QPageLayout::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.

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::paintRectPoints() const

Returns the paintable rectangle in rounded Postscript Points (1/72 of an inch).

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.

bool QPageLayout::setBottomMargin(qreal bottomMargin)

Sets the bottom page margin of the page layout to bottomMargin. Returns true if the margin was successfully set.

The units used are those currently defined for the layout. To use different units call setUnits() first.

If in the default StandardMode then the new margin must fall between the minimum margin set and the maximum margin allowed by the page size, otherwise the margin will not be set.

If in FullPageMode then any margin values will be accepted.

See also setMargins() and margins().

bool QPageLayout::setLeftMargin(qreal leftMargin)

Sets the left page margin of the page layout to leftMargin. Returns true if the margin was successfully set.

The units used are those currently defined for the layout. To use different units call setUnits() first.

If in the default StandardMode then the new margin must fall between the minimum margin set and the maximum margin allowed by the page size, otherwise the margin will not be set.

If in FullPageMode then any margin values will be accepted.

See also setMargins() and margins().

bool QPageLayout::setMargins(const QMarginsF &margins)

Sets the page margins of the page layout to margins Returns true if the margins were successfully set.

The units used are those currently defined for the layout. To use different units then call setUnits() first.

If in the default StandardMode then all the new margins must fall between the minimum margins set and the maximum margins allowed by the page size, otherwise the margins will not be set.

If in FullPageMode then any margin values will be accepted.

See also margins() and units().

void QPageLayout::setMinimumMargins(const QMarginsF &minMargins)

Sets the minimum page margins of the page layout to minMargins.

It is not recommended to override the default values set for a page size as this may be the minimum printable area for a physical print device.

If the StandardMode mode is set then the existing margins will be clamped to the new minMargins and the maximum allowed by the page size. If the FullPageMode is set then the existing margins will be unchanged.

See also minimumMargins() and setMargins().

void QPageLayout::setMode(QPageLayout::Mode mode)

Sets a page layout mode to mode.

See also mode().

void QPageLayout::setOrientation(QPageLayout::Orientation orientation)

Sets the page orientation of the page layout to orientation.

Changing the orientation does not affect the current margins or the minimum margins.

See also orientation().

void QPageLayout::setPageSize(const QPageSize &pageSize, const QMarginsF &minMargins = QMarginsF(0, 0, 0, 0))

Sets the page size of the page layout to pageSize.

Optionally define the minimum allowed margins minMargins, e.g. the minimum margins able to be printed by a physical print device, otherwise the minimum margins will default to 0.

If StandardMode is set then the existing margins will be clamped to the new minimum margins and the maximum margins allowed by the page size. If FullPageMode is set then the existing margins will be unchanged.

See also pageSize().

bool QPageLayout::setRightMargin(qreal rightMargin)

Sets the right page margin of the page layout to rightMargin. Returns true if the margin was successfully set.

The units used are those currently defined for the layout. To use different units call setUnits() first.

If in the default StandardMode then the new margin must fall between the minimum margin set and the maximum margin allowed by the page size, otherwise the margin will not be set.

If in FullPageMode then any margin values will be accepted.

See also setMargins() and margins().

bool QPageLayout::setTopMargin(qreal topMargin)

Sets the top page margin of the page layout to topMargin. Returns true if the margin was successfully set.

The units used are those currently defined for the layout. To use different units call setUnits() first.

If in the default StandardMode then the new margin must fall between the minimum margin set and the maximum margin allowed by the page size, otherwise the margin will not be set.

If in FullPageMode then any margin values will be accepted.

See also setMargins() and margins().

void QPageLayout::setUnits(QPageLayout::Unit units)

Sets the units used to define the page layout.

See also units().

void QPageLayout::swap(QPageLayout &other)

Swaps this page layout with other. This function is very fast and never fails.

QPageLayout::Unit QPageLayout::units() const

Returns the units the page layout is currently defined in.

See also setUnits().

QPageLayout &QPageLayout::operator=(QPageLayout &&other)

Move-assigns other to this QPageLayout instance, transferring the ownership of the managed pointer to this instance.

QPageLayout &QPageLayout::operator=(const QPageLayout &other)

Assignment operator, assigns other to this.
