（五十二）c#Winform自定义控件-LED数字
2021-02-05 00:16
标签：一点 完整 size 入行 == 一个用户 code graph 内容 入行已经7,8年了，一直想做一套漂亮点的自定义控件，于是就有了本系列文章。 GitHub：https://github.com/kwwwvagaa/NetWinformControl 码云：https://gitee.com/kwwwvagaa/net_winform_custom_control.git 如果觉得写的还行，请点个 star 支持一下吧 欢迎前来交流探讨： 企鹅群568015492 麻烦博客下方点个【推荐】，谢谢 https://www.cnblogs.com/bfyx/p/11364884.html 使用GID+画的，不了解的话请自行百度 添加一个类UCLEDNum ，继承UserControl 将数字拆分为单独的字，然后根据显示位置进行画出来，将显示位置定义为如下所示 从上面可以看出，定义了1-7的位置，然后定义一个数字对应的显示列表 你看到了还有“-”，“：”，“.”这3个符号，是为了时间和数字时候使用 然后定义一个矩形区域来用作绘画区域，并且在SizeChanged事件中赋值 然后就是几个属性 最重要的重绘 完工，看下完整代码和效果 以上就是单个字符的了 =======================分割线========================== 下面对数字控件处理 添加一个用户控件UCLEDNums 添加一点属性前提
