Member Function Documentation

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

virtual

Set whether the sprite has widget events.

Disabling events disconnects all of the DtOutlinedPolygon 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::DtOutlinedPolygon::eventsEnabled ( ) const

Get whether events are already enabled.

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

virtual

Set the number of vertices, set the number of vertices before setting their parameters (position, color etc).

Implements makVrv::DtPolygon.

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

virtual

Get the vertex count.

Implements makVrv::DtPolygon.

virtual void makVrv::DtOutlinedPolygon::set2DPositions ( const std::vector< float > & vertices )

virtual

Set the number of vertices and their positions.

vertices must be x,y,z encoded triplets.

Implements makVrv::DtPolygon.

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

virtual

Set the vertex positions.

Implements makVrv::DtPolygon.

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

virtual

Get the vertex position.

Implements makVrv::DtPolygon.

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

virtual

Set one vertex position.

Warning: It is much more efficient to update all vertices using setPositions if several change.

Implements makVrv::DtPolygon.

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

virtual

Get the vertex position.

Implements makVrv::DtPolygon.

virtual void makVrv::DtOutlinedPolygon::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.

Implements makVrv::DtPolygon.

virtual void makVrv::DtOutlinedPolygon::setVertexColor	(	unsigned int	index,
		float	r,
		float	g,
		float	b,
		float	a
	)

virtual

Set the color of a specific vertex.

Implements makVrv::DtPolygon.

virtual void makVrv::DtOutlinedPolygon::getVertexColor	(	unsigned int	index,
		float &	r,
		float &	g,
		float &	b,
		float &	a
	)

virtual

Get the color of a specific vertex.

Implements makVrv::DtPolygon.

virtual void makVrv::DtOutlinedPolygon::setColor	(	float	r,
		float	g,
		float	b,
		float	a
	)

virtual

Set entire poly-line color.

Implements makVrv::DtPolygon.

virtual void makVrv::DtOutlinedPolygon::getColor	(	float &	r,
		float &	g,
		float &	b,
		float &	a
	)		const

virtual

Get the poly-line color.

Implements makVrv::DtPolygon.

void makVrv::DtOutlinedPolygon::setStippleParameters	(	unsigned int	scale,
		unsigned short	pattern
	)

Set the entire poly-line stipple.

Scale is from 1-256. Pattern is 16 bit mask. Warning Stippled lines are rendered significantly slower than non-Stippled lines. Setting the pattern to NoStipple causes the line not to be stippled anymore.

virtual void makVrv::DtOutlinedPolygon::setStipple ( unsigned int stipplePattern )

virtual

Set the stipple pattern.

This pattern is used as a bitmask against the pixels of the polygon The default value is 0xFFFFFFFF, which is equivalent to no stippling

Implements makVrv::DtPolygon.

virtual void makVrv::DtOutlinedPolygon::setOutlineWidth ( float )

virtual

Sets the width of the line segments that comprise the polygon.

virtual void makVrv::DtOutlinedPolygon::setEventOutlineWidth ( 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 int makVrv::DtOutlinedPolygon::group ( ) const

virtual

Returns the group that the polygon is on (for Z-Ordering)

Implements makVrv::DtPolygon.

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

virtual

Sets the group for Z-ordering.

Implements makVrv::DtPolygon.

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

virtual

Creates and initializes a new segment.

Reimplemented in makVrv::DtTexturedOutlinedPolygon.

virtual void makVrv::DtOutlinedPolygon::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.
