Member Function Documentation

boundingBox()

QgsRectangle QgsAnnotationMarkerItem::boundingBox ( ) const

overridevirtual

Returns the bounding box of the item's geographic location, in the parent layer's coordinate reference system.

Implements QgsAnnotationItem.

Definition at line 97 of file qgsannotationmarkeritem.cpp.

clone()

QgsAnnotationMarkerItem * QgsAnnotationMarkerItem::clone ( )

overridevirtual

Returns a clone of the item.

Ownership is transferred to the caller.

Implements QgsAnnotationItem.

Definition at line 89 of file qgsannotationmarkeritem.cpp.

create()

QgsAnnotationMarkerItem * QgsAnnotationMarkerItem::create ( )

static

Creates a new marker annotation item.

Definition at line 69 of file qgsannotationmarkeritem.cpp.

geometry()

QgsPointXY QgsAnnotationMarkerItem::geometry ( ) const

inline

Returns the point geometry of the marker.

The coordinate reference system for the point will be the parent layer's QgsAnnotationLayer::crs().

setGeometry()

Definition at line 62 of file qgsannotationmarkeritem.h.

readXml()

bool QgsAnnotationMarkerItem::readXml ( const QDomElement &  element, const QgsReadWriteContext &  context  )

overridevirtual

Reads the item's state from the given DOM element.

Implements QgsAnnotationItem.

Definition at line 74 of file qgsannotationmarkeritem.cpp.

render()

void QgsAnnotationMarkerItem::render ( QgsRenderContext &  context, QgsFeedback *  feedback  )

overridevirtual

Renders the item to the specified render context.

The feedback argument can be used to detect render cancellations during expensive render operations.

Implements QgsAnnotationItem.

Definition at line 37 of file qgsannotationmarkeritem.cpp.

setGeometry()

void QgsAnnotationMarkerItem::setGeometry ( const QgsPoint &  geometry )

inline

Sets the point geometry location of the marker.

The coordinate reference system for the point will be the parent layer's QgsAnnotationLayer::crs().

See also

geometry()

Definition at line 71 of file qgsannotationmarkeritem.h.

setSymbol()

void QgsAnnotationMarkerItem::setSymbol

(

QgsMarkerSymbol *

symbol

)

Sets the symbol used to render the marker item.

The item takes ownership of the symbol.

See also

symbol()

Definition at line 107 of file qgsannotationmarkeritem.cpp.

const QgsMarkerSymbol * QgsAnnotationMarkerItem::symbol

(

)

const

Returns the symbol used to render the marker item.

See also

setSymbol()

Definition at line 102 of file qgsannotationmarkeritem.cpp.

type()

QString QgsAnnotationMarkerItem::type ( ) const

overridevirtual

Returns a unique (untranslated) string identifying the type of item.

Implements QgsAnnotationItem.

Definition at line 32 of file qgsannotationmarkeritem.cpp.

writeXml()

bool QgsAnnotationMarkerItem::writeXml ( QDomElement &  element, QDomDocument &  document, const QgsReadWriteContext &  context  ) const

overridevirtual

Writes the item's state into an XML element.

Implements QgsAnnotationItem.

Definition at line 58 of file qgsannotationmarkeritem.cpp.
