    def selectRaster():
        raster = tkFileDialog.askopenfilename(filetypes = [(tif影像, .tif),(all files, .*)])          #弹出选择TIF对话框
        rasterpathvar.set(raster)

    def selectFeature():

    buffervar.set(0)

    Label(root4,text = "选择输出文件夹:").grid(row = 2, column = 0)
    Button(root4, text = "浏览", command = selectRaster).grid(row = 0, column = 2)           #按钮设置
    Button(root4, text = "浏览", command = selectFeature).grid(row = 1, column = 2)

    comboxlist.grid(row = 5, column = 1)                 #设置下拉框位置
    comboxlist.current(0)                    #设置下拉框默认值为元组第一个值

    Entry(root4, textvariable = rasterpathvar).grid(row = 0, column = 1)            #设置输入框,值为选择TIF的路径
    Entry(root4, textvariable = featurepathvar).grid(row = 1, column = 1)          #这只输入框,值为选择裁切要素的路径
    Entry(root4, textvariable = fieldvar).grid(row = 3, column = 1)              #设置输入框,值为输入要素的字段
    entry1 = Entry(root4, textvariable = buffervar).grid(row = 4, column = 1)      #    设置输入框,值为输入缓冲距离
    Entry(root4, textvariable = outpathvar).grid(row = 2, column = 1)  #    设置输入框,值为输出文件夹路径
    Button(root4, text = "开始",command = ClipRaster).grid(row = 6, column = 2)   #    设置按钮,运行ClipRaster函数
    root4.mainloop()
