Active gadget?

I see that there is a command to ActivateWindow
and a related command ActiveWindow.

I also see a command ActivateGadget
but ... no related command ActiveGadget.

Does anyone know how to find out this info?
Or am I going to have to keep track of it manually (which I don't want to do because I have a LOT of gadgets)?
