    lyt.Add(controls[1], 200)
    controls[1].Selected(7, True)
    controls[1].MultiSelect = True


def CreateTool():    
    # Tool creation will serve as the hub for all other controls
    t = FBCreateUniqueTool("List Example")    
    PopulateLayout(t)    
    ShowTool(t)


CreateTool()

大家仔细研究一下代码上方的几个函数，敲一敲，decomposition and refactor!
