hi all,

I made a class who have to draw a simple line (see below)
but I don't know why when I delete CLine class, the line is always visible
(but the class is well deleted)

I put the code of the class.

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
class CLine{


        private:
                osg::ref_ptr<osg::Geode> SegmentGeode;
                osg::ref_ptr<osg::Geometry> SegmentGeometry;

       public:

                CLine(  double x1,double y1,double z1, double x2,double
y2,double z2);

        ~CLine();

};
-----------------------------------------------------------------------------------------------------------------



CLine::CLine(  double x1,double y1,double z1,
                double x2,double y2,double z2){

        SegmentGeode = new osg::Geode();   //
        SegmentGeometry = new osg::Geometry();

        SegmentGeode->addDrawable(SegmentGeometry.get());
        CGeneral::instance().root->addChild(SegmentGeode.get());

        osg::Vec3Array* SegmentVertices = new osg::Vec3Array;
        SegmentVertices->push_back( osg::Vec3( x1, y1, z1) );
        SegmentVertices->push_back( osg::Vec3( x2, y2, z2) );

        SegmentGeometry->setVertexArray( SegmentVertices );
        osg::DrawElementsUInt* SegmentBase = new
osg::DrawElementsUInt(osg::PrimitiveSet::LINES, 0);
        SegmentBase->push_back(0);
        SegmentBase->push_back(1);
        SegmentGeometry->addPrimitiveSet(SegmentBase);

        osg::Vec4Array* colors = new osg::Vec4Array;
        colors->push_back(osg::Vec4(1.0f,1.0f,0.0f,1.0f));
        SegmentGeometry->setColorArray(colors);
        SegmentGeometry->setColorBinding(osg::Geometry::BIND_PER_VERTEX);

        CGeneral::instance().root->addChild(SegmentGeode.get());
}

CLine::~CLine(){

        CGeneral::instance().root->removeChild(SegmentGeode.get());
        SegmentGeode = 0;

}




THANKS;
