#include <GLInteractor.h>

Inherits tlp::InteractorComponent.

Public Slots
virtual bool	compute (tlp::GlMainWidget *)
virtual bool	draw (tlp::GlMainWidget *)

Detailed Description

The GLInteractorComponent class is an InteractorComponent that can do OpenGL rendering on a GlMainWidget.

Warning

Only GLInteractorComponent that are stored into a GLInteractorComposite will be able to do OpenGL rendering. Storing them into an InteractorComposite will have no effect.

GLInteractorComponent are meant to be stored into a GLInteractorComposite When installed on a GlMainWidget, this interactor will have two new methods getting called:

• draw: Draws a visual feedback into the OpenGL scene. This is called after the scene was rendered
• compute: Allows the interactor to do some pre-initialisation steps before the OpenGL scene is rendered.
