display the number of every node in 3d surfaceplot

[panagiotisss]

hi! i want to display the number of every node in a 3d surfaceplot i add the data with loadFromData(Qwt3D::TripleField,Qwt3D::CellField ); but i only get the lines(edges) in 3dspace how can i display also a number for every node?? the code that i use is

alpha::alpha(QWidget* parent) 
	:SurfacePlot(parent)
{
	setPlotStyle(Qwt3D::WIREFRAME);
    setRotation(30,0,15);
	setScale(1,1,1);    
	setZoom(0.9);
	setShift(0.15,0,0);   
 
 
 
	//const QModelIndex mi;
 
 
//m->getdata1() returns Qwt3D::TripleField and  m->GetData2() returns Qwt3D::CellField     
	loadFromData(m->GetData1(), m->GetData2());
 
	 for (unsigned i=0; i!=coordinates()->axes.size(); ++i)   
	 {   
		coordinates()->axes[i].setMajors(7);   
		coordinates()->axes[i].setMinors(4);   
	 }   
 
	coordinates()->axes[Qwt3D::X1].setLabelString("x-axis");
	coordinates()->axes[Qwt3D::Y1].setLabelString("y-axis");
	coordinates()->axes[Qwt3D::Z1].setLabelString("z-axis");
 
	setCoordinateStyle(Qwt3D::FRAME);
     setMeshLineWidth(2);
	updateData();
	updateGL();
}

alpha::alpha(QWidget* parent) 
	:SurfacePlot(parent)
{
	setPlotStyle(Qwt3D::WIREFRAME);
    setRotation(30,0,15);
	setScale(1,1,1);    
	setZoom(0.9);
	setShift(0.15,0,0);   
	
	
     
	//const QModelIndex mi;
	
	
//m->getdata1() returns Qwt3D::TripleField and  m->GetData2() returns Qwt3D::CellField     
	loadFromData(m->GetData1(), m->GetData2());

	 for (unsigned i=0; i!=coordinates()->axes.size(); ++i)   
	 {   
		coordinates()->axes[i].setMajors(7);   
		coordinates()->axes[i].setMinors(4);   
	 }   

	coordinates()->axes[Qwt3D::X1].setLabelString("x-axis");
	coordinates()->axes[Qwt3D::Y1].setLabelString("y-axis");
	coordinates()->axes[Qwt3D::Z1].setLabelString("z-axis");
