V3d_Viewer::ActivateGrid Incomplete?!

I've just started working with OpenCascade, and im trying to activeate a grid in a V3d_Viewer. Using the help file i've enumerated the Aspect_GridType but cannot find any references to Aspect_GridDrawMode - in oreder to call ActivateGrid().
Can anyone help me?

see Aspect.cdl for the Aspect_GridDrawMode enumeration.
