How to make a toolbar toggle?

i'm loading a toolbar with five 16x16 buttons on the strip. I want only one of the five buttons to be selected at once (have a toggled appearance). And if a new one is toggled then the previous selected goes back to normal. Anyone know how to do it?

Also, this won't put my toolbar at the x,y position:

Local toolbar:TGadget=CreateToolBar("toolbar.bmp",100,60,256,16,window)

:(

Nm...i found a way to kludge it~
