(三十一)c#Winform自定义控件-文本框(四)-HZHControls
官网
前提
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。

准备工作
终于到文本框了,文本框将包含原文本框扩展,透明文本框,数字输入文本框,带边框文本框
本文将讲解带边框文本框,可选弹出键盘样式,继承自控件基类UCControlBase
同时用到了无焦点窗体和键盘,如果你还没有了解,请前往查看
开始
添加用户控件,命名UCTextBoxEx,继承自UCControlBase

你也许注意到了m_frmAnchor_VisibleChanged事件,当键盘窗体显示的时候,启动手写输入软件(这里用了搜狗的手写),将手写软件窗体包含进键盘窗体中来实现手写功能
