I have written a compound widget cw_buttons to manage this and some
other
button functions.

http://www.fz-juelich.de/icg/icg-i/idl_icglib/idl_source/idl _html/dbase/download/cw_buttons.tar.gz

Here is a small example

PRO xtest_event,ev
WIDGET_CONTROL,ev.id, get_uval=cmd
CASE cmd OF
'TEST': BEGIN
WIDGET_CONTROL,ev.id,get_value=v
HELP,v,/str
idx=WHERE(v.set EQ 1,count)
IF count GT 0 THEN PRINT,v.value[idx]
END

'DONE': WIDGET_CONTROL,ev.top,/destroy
ELSE :
ENDCASE

END

PRO xtest
a=WIDGET_BASE(row=2)
value={value:['LOG','ALOG','SIN'],set:[0,0,1]}
b=cw_buttons(a,value=value,uvalue='TEST',col=2, $
/exclusive,frame=2,xoffset=20,yoffset=0,button_frame=1)
b=WIDGET_BUTTON(a,value='DONE',uvalue='DONE')

WIDGET_CONTROL,/realize,a
XMANAGER,'xtest',a
END
