Member Function Documentation

◆ clone()

QgsSvgAnnotation * QgsSvgAnnotation::clone ( ) const

overridevirtual

Clones the annotation, returning a new copy of the annotation reflecting the annotation's current state.

Implements QgsAnnotation.

Definition at line 34 of file qgssvgannotation.cpp.

◆ create()

static QgsSvgAnnotation* QgsSvgAnnotation::create ( )

inlinestatic

Returns a new QgsSvgAnnotation object.

Definition at line 62 of file qgssvgannotation.h.

◆ filePath()

QString QgsSvgAnnotation::filePath ( ) const

inline

Returns the file path for the source SVG file.

See also: setFilePath()

Definition at line 57 of file qgssvgannotation.h.

◆ readXml()

void QgsSvgAnnotation::readXml	(	const QDomElement &	itemElem,
		const QgsReadWriteContext &	context
	)

overridevirtual

Restores the annotation's state from a DOM element.

Derived classes should call _readXml() within their implementation of this method.

See also: writeXml(); _readXml()

Implements QgsAnnotation.

Definition at line 51 of file qgssvgannotation.cpp.

◆ renderAnnotation()

void QgsSvgAnnotation::renderAnnotation	(	QgsRenderContext &	context,

overrideprotectedvirtual

Renders the annotation's contents to a target /a context at the specified /a size.

Derived classes should implement their custom annotation drawing logic here.

Implements QgsAnnotation.

Definition at line 62 of file qgssvgannotation.cpp.

◆ setFilePath()

void QgsSvgAnnotation::setFilePath ( const QString & file )

Sets the file path for the source SVG file.

See also: filePath()

Definition at line 94 of file qgssvgannotation.cpp.

◆ writeXml()

void QgsSvgAnnotation::writeXml	(	QDomElement &	elem,
		QDomDocument &	doc,
		const QgsReadWriteContext &	context
	)		const

overridevirtual

Writes the annotation state to a DOM element.

Derived classes should call _writeXml() within their implementation of this method.
