自定义的CheckBox样式，mark一下，方便以后参考复用
模板
一般CheckBox模板太难看了，所以肯定要重写其中的模板ControlTemplate
- 外边框 俩个Rectangle，用于定义复选框选中/未选中时的背景色和边框样式
- 对勾√ 通过俩个path组合，并控制其显示，用于定义选中状态
选中状态
模板状态为未选中状态和选中状态，设置为默认未选中就好了。
通过Trigger设置选中状态的样式显示
<Style x:Key="CheckBoxStyle" TargetType="{x:Type CheckBox}">
<Setter Property="SnapsToDevicePixels" Value="true" />
<Setter Property="OverridesDefaultStyle" Value="False" />
<Setter Property="FocusVisualStyle" Value="{DynamicResource CheckBoxFocusVisual}" />
<Setter Property="Height" Value="25"/>
<Setter Property="IsChecked" Value="False"/>
<Setter Property="Margin" Value="0,20"/>
<Setter Property="Template">

<ControlTemplate.Triggers>
<Trigger Property="IsChecked" Value="True">
<Setter TargetName="CheckedMark" Property="Visibility" Value="Visible"></Setter>
<Setter TargetName="CheckBoxRectangle" Property="Fill" Value="#FF00A8E0"></Setter>
<Setter TargetName="CheckBoxRectangle" Property="Opacity" Value="1"></Setter>
<Setter TargetName="CheckBoxRectangleOut" Property="Stroke" Value="Transparent"></Setter>

</Setter>

当然如果需要点动画的话，可以添加个Strory，也是不错的。
EventTrigger ，设置事件触发源如Click，Mouse.MouseEnter
有意思的是HandoffBehavior属性，其默认值 SnapshotAndReplace
- SnapshotAndReplace 新动画将替换它们所应用到的属性上的任何现有动画 -- 即新动画立即替换原有动画
- Compose 将通过把新动画追加到组合链的末尾来组合新动画和现有动画- - 即完成原有动画后，再执行新动画
