WPF前端：一个简单的数值设置样式卡片，支持MVVM绑定

默认是两套笔刷，如果是浅色背景，要把深色背景的画笔注释掉，然后把浅色画笔解除注释。

用于数量、范围是确定的，并且点击不需要太多次的情况（如果范围太大，需要点击太多次，使用滑动条而不是按钮）

为什么不用输入框？因为在触控屏上不方便输入，有时候范围比较小，举例：设置模块温度报警阈值，50-100℃，每5℃一个档位，就可以使用上面的自定义控件来设置。

使用时只需要设置如下几个简单参数即可，非常简单：

Describe：最下方的详细描述

ItemTitle：最上方显示的标题

MaxValue和MinValue：最大和最小值，对能更改的数值进行限制

Step：按钮每点击一次，更改的数值大小

Unit：单位

Value：实际数值，支持MVVM绑定，需要设置Mode为双向

引用：项目中添加Controls文件夹，存放自定义控件，然后新建一个用户控件，命名为SettingsItem

代码（前端）：x:Class后面需要换成自己项目里的

在主页使用时：先引用名称空间：Controls（项目名称换成自己的）

使用：

        <controls:SettingsItem
            Grid.Row="1"
            Width="500"
            Height="160"
            Describe="设备温度报警阈值，超出此温度设备将报警"
            ItemTitle="报警阈值"
            MaxValue="100"
            MinValue="50"
            Step="5"
            Unit="℃"
            Value="{Binding Temp, Mode=TwoWay}" />
