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)

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
virtual tlp::GlGraphRenderer::~GlGraphRenderer ( )

Member Function Documentation

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 84 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.
