Member Function Documentation

virtual void makVrv::DtFilledPolygon::setFillType ( FillType type ) [virtual]

Set the quad fill type.

Calling fill type resets the fill parameter, thus the fill parameter must be reset after calling setFillType.

virtual FillType makVrv::DtFilledPolygon::fillType ( ) const [virtual]

Get the fill type.

virtual void makVrv::DtFilledPolygon::setFillParameter	(	unsigned int	param,
		unsigned int	fullStipplePattern[32] = `0`
	)		`[virtual]`

Set the quad fill parameter.

In Texture mode the parameter is the texture index. If the full stippledPattern (aka a full 32x32 bit array) the initial param is ignored.

virtual void makVrv::DtFilledPolygon::getFillParameter	(	unsigned int &	paramOut,
		unsigned int	fullStipplePatternOut[32]
	)		const `[virtual]`

Get the quad fill parameters.

virtual void makVrv::DtFilledPolygon::setEventsEnabled	(	bool	enabled,
		unsigned long	long = `0`
	)		`[virtual]`

Set whether the sprite has widget events.

Disabling events disconnects all of the DtFilledPolygon signals The user data is set when enabling the events, to change only the user data make multiple calls with enabled=true

Implements makVrv::DtPolygon.

bool makVrv::DtFilledPolygon::eventsEnabled ( ) const

Get whether events are already enabled.

virtual void makVrv::DtFilledPolygon::setVertexCount ( unsigned int vertexCount ) [virtual]

Set the number of vertices, any newly created vertices will be black and add 0,0,0 so setColor/setPosition may be necessary.

Implements makVrv::DtPolygon.

virtual unsigned int makVrv::DtFilledPolygon::vertexCount ( ) const [virtual]

Get the vertex count.

Implements makVrv::DtPolygon.

virtual void makVrv::DtFilledPolygon::set2DPositions ( const std::vector< float > & vertices ) [virtual]

Set the number of vertices and their positions.

Implements makVrv::DtPolygon.

virtual void makVrv::DtFilledPolygon::set2DPosition	(	unsigned int	vertexIndex,
		float	x,
		float	y
	)		`[virtual]`

Set one vertex position.

NOTE it is much more efficient to update all vertices using setPositions if several change.

Implements makVrv::DtPolygon.

virtual void makVrv::DtFilledPolygon::set2DCentroidPosition	(	float	x,
		float	y
	)		`[virtual]`

Sets the position of the polygon's centroid.

virtual void makVrv::DtFilledPolygon::get2DPosition	(	unsigned int	vertexIndex,
		float &	x,
		float &	y
	)		const `[virtual]`

Get the vertex position.

Implements makVrv::DtPolygon.

virtual void makVrv::DtFilledPolygon::set3DPosition	(	unsigned int	vertexIndex,
		float	x,
		float	y,
		float	z,
		float	w
	)		`[virtual]`

Set one vertex position.

Implements makVrv::DtPolygon.

virtual void makVrv::DtFilledPolygon::set3DCentroidPosition	(	float	x,
		float	y,
		float	z,
		float	w
	)		`[virtual]`

Sets the position of the polygon's centroid.

virtual void makVrv::DtFilledPolygon::get3DPosition	(	unsigned int	index,
		float &	x,
		float &	y,
		float &	z,
		float &	w
	)		const `[virtual]`

Get the vertex position.

Implements makVrv::DtPolygon.

void makVrv::DtFilledPolygon::set3DDirectionAndLength	(	unsigned int	index,
		float	x,
		float	y,
		float	z,
		float	l
	)		`[virtual]`

Sets an optional 3D direction with a 2D length value for a vertex.

Parameters:

index	the index of the vertex to get the position of
x	x component of the position
y	y component of the position
z	z component of the position
l	l length of the vector offset in 2D.
