Text in 3D window

Hi,
I am still not able to get this resolved. Please help.

I was having problem with displaying 2D text in a 3D window. I managed to overcome it by creating my own class AIS_3DText.Now, I can display the 2d text in a 3D window but I am not able to set its color,font and angle. How do I do that? I tried,

Prs3d_TextAspect* textAspect = new Prs3d_TextAspect();
textAspect->SetAngle(angle);
textAspect->SetColor(aColor);
textAspect->SetFont(font);

Handle(AIS_3DText) aGraphicText = new AIS_3DText(aText,tmpPnt); // My own class
m_AISContext->SetColor(aGraphicText,aColor,Standard_False);
m_AISContext->Display(aGraphicText);

It does not seem to work.Can anybody help me?

Thanks in advance,
