Member Function Documentation

◆ abort()

bool QPreviewPaintEngine::abort ( )

overridevirtual

Instructs the print engine to abort the printing process. Returns true if successful; otherwise returns false.

Implements QPrintEngine.

Definition at line 172 of file qpaintengine_preview.cpp.

Here is the call graph for this function:

◆ begin()

bool QPreviewPaintEngine::begin ( QPaintDevice * pdev )

overridevirtual

Reimplement this function to initialise your paint engine when painting is to start on the paint device pdev. Return true if the initialization was successful; otherwise return false.

See also: end(), isActive()

Implements QPaintEngine.

Definition at line 83 of file qpaintengine_preview.cpp.

Here is the call graph for this function:

◆ drawPath()

void QPreviewPaintEngine::drawPath ( const QPainterPath & path )

overridevirtual

The default implementation ignores the path and does nothing.

Reimplemented from QPaintEngine.

Definition at line 117 of file qpaintengine_preview.cpp.

◆ drawPixmap()

void QPreviewPaintEngine::drawPixmap	(	const QRectF &	r,
		const QPixmap &	pm,
		const QRectF &	sr
	)

overridevirtual

Reimplement this function to draw the part of the pm specified by the sr rectangle in the given r.

Implements QPaintEngine.

Definition at line 135 of file qpaintengine_preview.cpp.

◆ drawPolygon()

void QPreviewPaintEngine::drawPolygon	(	const QPointF *	points,
		int	pointCount,
		PolygonDrawMode	mode
	)

overridevirtual

Reimplement this virtual function to draw the polygon defined by the pointCount first points in points, using mode mode.

Note: At least one of the drawPolygon() functions must be reimplemented.

Reimplemented from QPaintEngine.

Definition at line 123 of file qpaintengine_preview.cpp.

◆ drawTextItem()

void QPreviewPaintEngine::drawTextItem	(	const QPointF &	p,
		const QTextItem &	textItem
	)

overridevirtual

This function draws the text item textItem at position p. The default implementation of this function converts the text to a QPainterPath and paints the resulting path.

Reimplemented from QPaintEngine.

Definition at line 129 of file qpaintengine_preview.cpp.

◆ drawTiledPixmap()

void QPreviewPaintEngine::drawTiledPixmap	(	const QRectF &	rect,
		const QPixmap &	pixmap,
		const QPointF &	p
	)

overridevirtual

Reimplement this function to draw the pixmap in the given rect, starting at the given p. The pixmap will be drawn repeatedly until the rect is filled.

Reimplemented from QPaintEngine.

Definition at line 141 of file qpaintengine_preview.cpp.

◆ end()

bool QPreviewPaintEngine::end ( )

overridevirtual

Reimplement this function to finish painting on the current paint device. Return true if painting was finished successfully; otherwise return false.

See also: begin(), isActive()

Implements QPaintEngine.

Definition at line 100 of file qpaintengine_preview.cpp.

Here is the caller graph for this function:

◆ metric()

int QPreviewPaintEngine::metric ( QPaintDevice::PaintDeviceMetric id ) const

overridevirtual

Returns the metric for the given id.

Implements QPrintEngine.

Definition at line 207 of file qpaintengine_preview.cpp.

◆ newPage()

bool QPreviewPaintEngine::newPage ( )

overridevirtual

Instructs the print engine to start a new page. Returns true if the printer was able to create the new page; otherwise returns false.

Implements QPrintEngine.

Definition at line 147 of file qpaintengine_preview.cpp.

Here is the call graph for this function:

◆ pages()

QList< const QPicture * > QPreviewPaintEngine::pages ( )

Definition at line 182 of file qpaintengine_preview.cpp.

◆ printerState()

QPrinter::PrinterState QPreviewPaintEngine::printerState ( ) const

overridevirtual

Returns the current state of the printer being used by the print engine.

Implements QPrintEngine.

Definition at line 213 of file qpaintengine_preview.cpp.

◆ property()

QVariant QPreviewPaintEngine::property ( PrintEnginePropertyKey key ) const

overridevirtual

Returns the print engine's property specified by key.

See also: setProperty()

Implements QPrintEngine.

Definition at line 201 of file qpaintengine_preview.cpp.

◆ setProperty()

void QPreviewPaintEngine::setProperty	(	PrintEnginePropertyKey	key,
		const QVariant &	value
	)

overridevirtual

Sets the print engine's property specified by key to the given value.

See also: property()

Implements QPrintEngine.

Definition at line 195 of file qpaintengine_preview.cpp.

◆ setProxyEngines()

void QPreviewPaintEngine::setProxyEngines	(	QPrintEngine *	printEngine,
		QPaintEngine *	paintEngine
	)

Definition at line 188 of file qpaintengine_preview.cpp.

◆ type()

QPaintEngine::Type QPreviewPaintEngine::type ( ) const

inlineoverridevirtual

Reimplement this function to return the paint engine \l{Type}.

Implements QPaintEngine.

Definition at line 86 of file qpaintengine_preview_p.h.

◆ updateState()

void QPreviewPaintEngine::updateState ( const QPaintEngineState & state )

overridevirtual

Reimplement this function to update the state of a paint engine.

When implemented, this function is responsible for checking the paint engine's current state and update the properties that are changed. Use the QPaintEngineState::state() function to find out which properties that must be updated, then use the corresponding \l {GetFunction}{get function} to retrieve the current values for the given properties.
