+
+slider 用来选择连续性的或者非连续性的数据. 默认是在一段最大值最小值间做任意值的选择. 如果你想选择间隔性的值, 例如0.0到50.0间,选择10, 15,...50.0这样的值, 给divisions设定一个非空的整数5,, 去分割区间范围.

+
+### **基本用法**
+
+关于slider有以下的术语:
+
+* **thumb** 滑块  用户可以水平拖拽移动的区域
+
+* **track** 滑轨 thumb 可以滑动的线条区域
+
+* **value indicator** 值指示器 当用户拖拽thumb的时候. 显示用户当前所选的属性值
+
+* **active** 选中区
+
+* **inactive** 非选中区
+
+如果**onChanged**属性为空或者**min** .. **max**给出的范围 为空（例如如果min等于max），则将禁用滑块。
+
+滑块小部件本身不保持任何状态State。相反，当滑块状态发生变化时，窗口小部件会调用 **onChanged** 回调。大多数使用滑块的小部件将侦听 **onChanged** 回调并使用新值重建滑块以更新滑块的视觉外观。要知道值何时开始更改，或何时更改，请设置可选回调**onChangeStart**或**onChangeEnd**。
+
+默认情况下，滑块将尽可能宽，垂直居中。当给定无限制约束时，它将尝试使轨道宽144像素（每边有边距）并垂直收缩。
