+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as
+contributors and maintainers pledge to making participation in our project and
+our community a harassment-free experience for everyone, regardless of age, body
+size, disability, ethnicity, sex characteristics, gender identity and expression,
+level of experience, education, socio-economic status, nationality, personal
+appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment
+include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or
+ advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic
+ address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+ professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable
+behavior and are expected to take appropriate and fair corrective action in
+response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or
+reject comments, commits, code, wiki edits, issues, and other contributions
+that are not aligned to this Code of Conduct, or to ban temporarily or
+permanently any contributor for other behaviors that they deem inappropriate,
+threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces
+when an individual is representing the project or its community. Examples of
+representing a project or community include using an official project e-mail
+address, posting via an official social media account, or acting as an appointed
+representative at an online or offline event. Representation of a project may be
+further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported by contacting the project team at zhu.yan@alibaba-inc.com. All
+complaints will be reviewed and investigated and will result in a response that
+is deemed necessary and appropriate to the circumstances. The project team is
+obligated to maintain confidentiality with regard to the reporter of an incident.
+Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good
+faith may face temporary or permanent repercussions as determined by other
+members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4,
+available at https://www.contributor-covenant.org/version/1/4/code-of-conduct.html

+
+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。

+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。
