source

The source point.

Member Function Documentation

virtual IlvMapGeometry* IlvMapText::copy ( ) const

virtual

Returns a copy of the object.

Returns

An IlvMapGeometry that must be deleted by the user.

Implements IlvMapGeometry.

virtual IlvClassInfo* IlvMapText::getClassInfo ( ) const

virtual

Returns the IlvClassInfo of the instance.

Returns

An IlvClassInfo that should not be modified nor deleted.

Implements IlvMapGeometry.

const IlvCoordinate& IlvMapText::getPoint

(

)

const

Returns the anchor point of the text.

Returns

The anchor point of the text.

virtual const IlvMapGeometry* IlvMapText::getSubElement ( IlUInt  index ) const

virtual

Returns a sub element of a collection geometry.

Parameters

index

The index of the sub-geometry to be retrieved.

Returns

The sub element of index index if the geometry is a collection or 0 if it is not.

Implements IlvMapGeometry.

virtual IlUInt IlvMapText::getSubElementCount ( ) const

virtual

Returns the number of elements contained in the geometry if the geometry is a collection.

Returns

The number of elements contained in the geometry if the geometry is a collection. If it is not, this method returns 0.

Implements IlvMapGeometry.

const char* IlvMapText::getText

(

)

const

Returns the value of the text.

Returns

The value of the text.

virtual IlBoolean IlvMapText::isCollection ( ) const

virtual

Checks if this geometry is a collection of other geometries.

The composite geometries predefined in Rogue Wave Views Maps are: IlvMapGeometryCollection, IlvMapMultiPoint, IlvMapSegmentString and its subclasses, IlvMapMultiCurve and IlvMapMultiArea.

Returns

IlTrue if the geometry is a collection of other geometries.

Implements IlvMapGeometry.

void IlvMapText::setPoint

(

const IlvCoordinate &

point

)

Sets the position of the text.

Parameters

point

An Anchor point for the text.

void IlvMapText::setText

(

const char *

text

)

Sets the value of the text.

Parameters

text	The value of the text.
