makVrv::DtOsgToGlContextTracker Class Reference

This class tracks gl contexts as they are created/destroyed per window creation/destruction. It is also what clients should hook to via signal_contextAboutToBeDestroyed for context destruction cleanup.

Member Function Documentation

static DtOsgToGlContextTracker& makVrv::DtOsgToGlContextTracker::instance ( DtDe &  de )

static

Access the singleton instance.

delete

not allowed

virtual void makVrv::DtOsgToGlContextTracker::run ( )

virtual

called per frame, per context via DtMainThreadJobsManager () which is in turn called per frame, per context via osg

virtual const void* makVrv::DtOsgToGlContextTracker::currentGlContext ( void  ) const

virtual

Current opengl context. Clients can use this in any function nested at any level under DtOsgRenderer::render() This function is useful, in lieu of proliferating wglGetCurrentContext/glXGetCurrentContext everywhere This function is useful, in lieu of proliferating DtGlUtils::glContext (which internally calls wglGetCurrentContext/glXGetCurrentContext) everywhere.

virtual void makVrv::DtOsgToGlContextTracker::contextAboutToBeDestroyed ( const void *  glContext )

virtual

The windowing api will call this. via the DtOsgAdapterQtWidget destructor. ***Do not use directly!!***.

Member Data Documentation

boost::signalslib::signal<void(const void*)> makVrv::DtOsgToGlContextTracker::signal_newContextAdded

This is the signal that vrv clients should connect to, to get the event that a new context was detected.

boost::signalslib::signal<void(const void*)> makVrv::DtOsgToGlContextTracker::signal_contextAboutToBeDestroyed

This is the signal that vrv clients should connect to, to get the event that the context is about to be destroyed.
