Inheritance diagram for TSLMultiPolyline:

[legend]

Detailed Description

This class provides access to set of Polylines. This is a geometry group that is drawn with the same set of rendering at the same time.

Rendering attributes can be set directly to this geometry using the inherited TSLEntityBase::setRendering method. This is called 'Entity Rendering'.

Rendering can be applied to a large range of geometry using 'Feature Rendering' which is set by the datalayer using TSLDataLayer::addFeatureRendering which creates a featureID. The featureID can then have attributes applied to it using TSLDataLayer::setFeatureRendering.

A featureID can be applied to geometry on creation, or it can be added later using TSLEntityBase::featureID.

Valid Rendering Attributes for TSLMultiPolyline:

TSLRenderingAttributeEdgeColour
TSLRenderingAttributeEdgeStyle
TSLRenderingAttributeEdgeThickness
TSLRenderingAttributeEdgeThicknessUnits

The above is not a complete list, see TSLRenderingAttributeInt, TSLRenderingAttributeDouble and TSLRenderingAttributeBool for more details.

◆ addPart() [1/2]

bool TSLMultiPolyline::addPart	(	const TSLCoordSet &	part,
		int	pos = -1 )

Add a coordinate to the TSLMultiPolyline.

Parameters

part	the coordset representing the TSLPolyline to add
pos	the position at which to add the polyline. By default the polyline will be added after the current last polyline. If the position entered is greater than the existing number of parts the polyline is also added after the current last polyline.

◆ addPart() [2/2]

bool TSLMultiPolyline::addPart	(	const TSLPolyline &	part,
		int	pos = -1 )

Add a coordinate to the TSLMultiPolyline.

Parameters

part	the TSLPolyline to add.
pos	the position at which to add the polyline. By default the polyline will be added after the current last polyline. If the position entered is greater than the existing number of parts the polyline is also added after the current last polyline.

◆ create() [1/3]

static TSLMultiPolyline * TSLMultiPolyline::create	(	TSLFeatureID	featureID,
