Detailed Description

Class used by GlGraphComposite to render the graph in OpenGL.

To create a graph renderer, you have to implement two functions : draw() and selectEntities()

Constructor & Destructor Documentation

tlp::GlGraphRenderer::GlGraphRenderer ( const GlGraphInputData * inputData )

inline

Constructor.

Parameters

inputData	: GlGraphInputData used by renderer to display the graph (in input data you have pointers on properties used to render nodes/edges
parameters	: GlGraphRenderingParameters used by renderer to display the graph

Definition at line 48 of file GlGraphRenderer.h.

virtual tlp::GlGraphRenderer::~GlGraphRenderer ( )

Destructor.

virtual void tlp::GlGraphRenderer::draw	(	float	lod,
		Camera *	camera
	)

pure virtual

This function is call by GlGraphComposite to draw the graph.

If you reimplement this function you have to render nodes/edges. It's the most important function of GlGraphRenderer

Parameters

lod	: lod used to this Rendering
camera	: camera used to this rendering

virtual void tlp::GlGraphRenderer::selectEntities	(	Camera *	camera,
		RenderingEntitiesFlag	type,
		int	x,
		int	y,
		int	w,
		int	h,
		std::vector< SelectedEntity > &	selectedEntities
	)

pure virtual

This function is call by GlGraphComposite to selected entities into the graph.

Parameters

type	: type of selected entities
x	: x of the selected zone
y	: y of the selected zone
w	: width of the selected zone
h	: height of the selected zone
selectedEntities	: you have to put selected entities into this vector

void tlp::GlGraphRenderer::setGraphModified ( bool graphModified )

inline

This function set if the content of the graph is modified.

Definition at line 85 of file GlGraphRenderer.h.

virtual void tlp::GlGraphRenderer::visitGraph	(	GlSceneVisitor *	visitor,
		bool	visitHiddenEntities = `false`
	)

virtual

You can use this funtion if you want to inject a visitor on the graph.
