A longer winded (so slower to return), but portable method is,

1. Get the number of gadgets in the window with 
"Window_EnumerateGadgets"
2. Loop getting the gadget flags with "Toolbox_MiscOp" (r2=64)
3. If the gadget is faded change it to unfaded with "Toolbox_MiscOp" 
(r2=65)
4. Get the pointer info with "Window_GetPointerInfo" r4=gadget number
5. If you changed the faded flag, change it back

I have done this in Basic.
