说明：  在stm32工程中，长按和短按的代码书写， 调用的读取按键状态的底层函数。封装成的按键函数代码。下面是函数的头文件，和.c文件的代码。使用定时器来扫描按键。(In STM32 project, the code of long press and short press is written, and the underlying function of reading key status is called. Encapsulated key function code. The following is the header file of the function, and the code of the. C file. Use a timer to scan keys.)

纯CSS圆角自适应宽度的导航菜单，水平布局的网站菜单，这个菜单的亮点有两个：1、圆角，2、宽度自适应。不管各个菜单项的菜单文字有多长，该项菜单的背景始终自动适合这种变化，完美的宽度自适应特效，值得推荐。

说明：  编辑框是常用控件之一，同时也是一种完全自实现较为繁琐的控件。本例实现了对编辑框的简单的自绘制，在保留其自身的强大功能的前提下，实现了编辑框的边框、背景、文字颜色以及禁用态的各种颜色的替换。 要想重绘，我们必须知道要绘什么。通过观察默认的编辑框我们可以很清楚的看到编辑框有三个最基础的部分需要我们绘制，他们分别是3D边框、背景和文字，再进一步分析我们会发现他们是一个基本窗口的两个部分，即客户区和非客户区。这样一来我们就知道应该用什么函数有针对性的绘制什么区域了，由于提供了源码，这里仅就基本原理和技术细节加以讨论，不过多地罗列代码。(Editor box is one of the common controls, and it is also a kind of control which is completely self-realization and tedious. This example realizes the simple self-drawing of the edit box, and realizes the replacement of the border, background, text color and various colors of the disabled state of the edit box while retaining its powerful function. To redraw, we must know what to draw. By observing the default edit box, we can clearly see that there are three most basic parts of the edit box that we need to draw. They are 3D border, background and text. Further analysis shows that they are two parts of a basic window, namely, client area and non-client area. In this way, we know which function should be used to draw which area. Since the source code is provided,)
