Member Function Documentation

bool RBlockReferenceData::applyTransformationTo ( REntity entity) const
RBox RBlockReferenceData::getBoundingBox ( bool  ignoreEmpty = false) const
The bounding box that contains this entity.

Reimplemented from REntityData.

double RBlockReferenceData::getDistanceTo ( const RVector point,
bool  limited = true,
double  range = 0.0,
bool  draft = false,
double  strictRange = RMAXDOUBLE 
) const
The shortest distance from this entity to the given point.
limitedLimit lines, arcs at end points, otherwise the orthogonal distance to the unlimited line / circle is returned.
rangeThis is returned for solid filled entities (solid filled or dense hatches, text entities) if the point is on the entity and the distance would be zero.
draftCalculate based on draft mode representation of the entity.
strictRangeIf limited, this is the maximum range from either end point of the entity. Zero to only return distances that are strictly orthogonal to the entity.

Reimplemented from REntityData.

QList< RVector > RBlockReferenceData::getInternalReferencePoints ( RS::ProjectionRenderingHint  hint = RS::RenderTop) const

Can be overwritten to return internal, resolved reference points.

This is used for example for block references in combination with snap to reference points. Default implementation returns same as getReferencePoints().

Reimplemented from REntityData.

RVector RBlockReferenceData::getPosition ( ) const
RBlock::Id RBlockReferenceData::getReferencedBlockId ( ) const
QString RBlockReferenceData::getReferencedBlockName ( ) const
QList< RVector > RBlockReferenceData::getReferencePoints ( RS::ProjectionRenderingHint  hint = RS::RenderTop) const
Vector of reference points of this entity. Reference points can usually be moved around by the user to change the geometry of the entity.

Implements REntityData.

double RBlockReferenceData::getRotation ( ) const
RVector RBlockReferenceData::getScaleFactors ( ) const
QList< QSharedPointer< RShape > > RBlockReferenceData::getShapes ( const RBox queryBox = RDEFAULT_RBOX,
bool  ignoreComplex = false 
) const
Shapes that represent the geometry of this entity.

Reimplemented from REntityData.

RVector RBlockReferenceData::getVectorTo ( const RVector point,
bool  limited = true,
double  strictRange = RMAXDOUBLE 
) const
The distance vector from this entity to the given point.
pointthe point to which the distance was measured
limited,:If true, an invalid vector is returned if the closest point on the entity is outside of the entity (e.g. in the extension line of a line or outside the start / end angle of an arc).

Reimplemented from REntityData.

void RBlockReferenceData::groundReferencedBlockId ( ) const
RVector RBlockReferenceData::mapToBlock ( const RVector v) const
bool RBlockReferenceData::mirror ( const RLine axis)

Reimplemented from REntityData.

bool RBlockReferenceData::move ( const RVector offset)

Moves this entity by the given offset.

Reimplemented from REntityData.

bool RBlockReferenceData::moveReferencePoint ( const RVector referencePoint,
const RVector targetPoint 

Moves the given reference point to the given target point or does nothing if this entity has no reference point as the given location.

True if a reference point has been moved successfully, false otherwise.

Implements REntityData.

QSharedPointer< REntity > RBlockReferenceData::queryEntity ( REntity::Id  entityId) const
The entity with the given ID, transformed according to the transformation of this block reference.
bool RBlockReferenceData::rotate ( double  rotation,
const RVector center = RDEFAULT_RVECTOR 

Reimplemented from REntityData.

bool RBlockReferenceData::scale ( const RVector scaleFactors,
const RVector center = RDEFAULT_RVECTOR 

Reimplemented from REntityData.

void RBlockReferenceData::setPosition ( const RVector p)
void RBlockReferenceData::setReferencedBlockId ( RBlock::Id  blockId)
void RBlockReferenceData::setReferencedBlockName ( const QString &  blockName)
void RBlockReferenceData::setRotation ( double  r)
void RBlockReferenceData::setScaleFactors ( const RVector sf)
void RBlockReferenceData::update ( ) const

Entities can reimplement this function to invalidate any internal cache (mark the entity as dirty).

Reimplemented from REntityData.

void RBlockReferenceData::update ( RObject::Id  entityId) const
