is it possible to draw with openGL in a carbon window?

CreateNewWindow( kDocumentWindowClass,

aglUpdateContext( tAGLContext);
glViewport(0,0, tWidth, tHeight);
glMatrixMode( GL_PROJECTION );
gluPerspective( 45.0, (GLdouble) tWidth/ (GLdouble) tHeight, 1.0 ,
200.0);
glClearColor( 0.0, 0.0, 0.0, 1.0 );
You can now draw to the tAGLContext.
