# ------------------------------------------------------------
# # 1、Scale的创建与设置
# ------------------------------------------------------------# ------------------------------------------------------------
# # 2、把尺子的内容显示在窗口中
# ------------------------------------------------------------# # ------------------------------------------------------------
# # 3、设置初始化尺子的位置
# # # 如： w1.set(19) ==>尺子w1的默认位置是19
# # ------------------------------------------------------------# ------------------------------------------------------------
# # 3.1、设置初始化尺子的间隔
# # 如： w1 = tk.Scale(window, from_=0, to=50, tickinterval=10)
# # # ==>> tickinterval=10 表标间隔10
# ------------------------------------------------------------# ------------------------------------------------------------
# # 4、设置初始化尺子的长度
# # # 如： w2 = tk.Scale(window, from_=0, to=200, tickinterval=50, length=200, orient=tk.HORIZONTAL )
# ------------------------------------------------------------# ------------------------------------------------------------
# # 5、显示尺子
# # 如： s2 = tk.Scale(window, from_=10, to=50, label='try me', length=200,
# showvalue=True, tickinterval=10, orient=tk.HORIZONTAL,
# resolution=0.01)
# ------------------------------------------------------------# ------------------------------------------------------------
# # 6、显示尺子 + 标签
# # 如： s2 = tk.Scale(window, from_=10, to=50, label='try me', length=200,
# showvalue=True, tickinterval=10, orient=tk.HORIZONTAL,
# resolution=0.01)
# ------------------------------------------------------------# ------------------------------------------------------------
# # 7、显示尺子 + 标签（显示尺子的内容）
# # 如： s2 = tk.Scale(window, from_=10, to=50, label='try me', length=200,
# showvalue=True, tickinterval=10, orient=tk.HORIZONTAL,
# resolution=0.01)
