Constructor & Destructor Documentation

makVrv::DtSegmentedLine::DtSegmentedLine	(	DtOverlayRenderer &	renderer,

	)

CTOR.

virtual makVrv::DtSegmentedLine::~DtSegmentedLine ( )

virtual

Constructor removed in favor of more generic constructor to take Overlay Renderer 09/04/2012. The line renderer is still used, however the new constructor allows for subclasses to use different renderer types DtSegmentedLine(DtLineRenderer& renderer,DtWidgetPicker& picker);.

virtual void makVrv::DtSegmentedLine::setEventsEnabled	(	bool	enabled,
		unsigned long long	userData = `0`
	)

virtual

Set whether the sprite has widget events. Disabling events disconnects all of the DtSegmentedLine signals The user data is set when enabling the events, to change only the user data make multiple calls with enabled=true.

virtual bool makVrv::DtSegmentedLine::eventsEnabled ( ) const

virtual

Get whether events are already enabled.

virtual void makVrv::DtSegmentedLine::setVertexCount ( unsigned int vertexCount )

virtual

Set the number of vertices, set the number of vertices before setting their parameters (position, color etc). The number of segments will be one less than the number of vertices set, with the count being at least 1 if the vertex count is > 0.

virtual unsigned int makVrv::DtSegmentedLine::vertexCount ( ) const

virtual

Get the vertex count. This count will always be one more than the number of segments available. Use segment count to get the number of segments.

virtual unsigned int makVrv::DtSegmentedLine::segmentCount ( ) const

virtual

Number of segments available.

virtual void makVrv::DtSegmentedLine::set2DPosition	(	unsigned int	vertexIndex,
		float	x1,
		float	y1
	)

virtual

Set the vertex positions.

virtual void makVrv::DtSegmentedLine::get2DPosition	(	unsigned int	vertexIndex,
		float &	x,
		float &	y
	)		const

virtual

Get the vertex position.

virtual void makVrv::DtSegmentedLine::set3DPosition	(	unsigned int	vertexIndex,
		float	x,
		float	y,
		float	z,
		float	w
	)

virtual

Set one vertex position. NOTE it is much more efficient to update all vertices using setPositions If several change.

virtual void makVrv::DtSegmentedLine::get3DPosition	(	unsigned int	vertexIndex,
		float &	x,
		float &	y,
		float &	z,
		float &	w
	)		const

virtual

Get the vertex position.

virtual void makVrv::DtSegmentedLine::set3DDirection	(	unsigned int	vertexIndex,
		float	x,
		float	y,
		float	z
	)

virtual

Set the normalized direction of the line in world space.

virtual void makVrv::DtSegmentedLine::get3DDirection	(	unsigned int	vertexIndex,
		float &	x,
		float &	y,
		float &	z
	)		const

virtual

Get the normalized direction of the vertex.

virtual void makVrv::DtSegmentedLine::setDirection2DLength	(	unsigned int	vertexIndex,
		float	length
	)

virtual

Set the length of the line in 2D space.

virtual float makVrv::DtSegmentedLine::direction2DLength ( unsigned int vertexIndex ) const

virtual

Get the length of the line in 2D space.

virtual void makVrv::DtSegmentedLine::setSegmentColor	(	unsigned int	segment,
		float	r,
		float	g,
		float	b,
		float	a
	)

virtual

Set the color of the segment (non-blending)

virtual void makVrv::DtSegmentedLine::setPointColor	(	unsigned int	point,
		float	r,
		float	g,
		float	b,
		float	a
	)

virtual

Set the color of the point (bleding)

virtual void makVrv::DtSegmentedLine::setStipplePattern	(	unsigned int	segment,
		unsigned int	pattern
	)

virtual

Set the stipple pattern.

virtual void makVrv::DtSegmentedLine::setStipplePattern	(	unsigned int	segment,
		unsigned int	scale,
		unsigned int	pattern
	)

virtual

virtual void makVrv::DtSegmentedLine::setWidth	(	unsigned int	segment,
		float	w
	)

virtual

Set the line width.

virtual void makVrv::DtSegmentedLine::setEventWidth ( float )

virtual

Sets the width of the event outline segments. To use the outline width as the event width set the event outline width to -1.0f;.

virtual DtLineSegmentInterface* makVrv::DtSegmentedLine::createAndInitNewSegment ( )

virtual

Creates and initializes a new segment.

Reimplemented in makVrv::DtTexturedLine.

virtual void makVrv::DtSegmentedLine::setGroup ( int )

virtual

The higher the z order the "closer" to the eyepoint this element will be drawn. Use this variable to stack overlay objects in the particular order you want them displayed.

Reimplemented in makVrv::DtTexturedLine.

virtual void makVrv::DtSegmentedLine::removeLineSegmentsUntilEndFrom ( int segmentCount )

protectedvirtual

Removed segments from the line starting at segmentCount until the end is reached.

Reimplemented in makVrv::DtTexturedLine.

virtual void makVrv::DtSegmentedLine::setLineSegment	(	int	,
		DtLineSegmentInterface *
	)

protectedvirtual

Sets the segment into the array. If array is smaller, increases size.

Reimplemented in makVrv::DtTexturedLine.

virtual void makVrv::DtSegmentedLine::slot_pickerDestroyed ( )

protectedvirtual

Called when the widget picker is destroyed, clears out pickable segment list and sets a flag to no longer use the picker.
