C++实现利用表盘来显示时间。设计思想：将系统时间通过极坐标转换为坐标，然后作直线，即表针。-C system to use the dial to show time. Design thinking : the system by the time of the polar coordinate conversion, and then straight for that hand.

用C++Builder做的类似电流表表盘的东西，可以用在需要仪表显示的程序中,clock

vc制作表盘,能够调整表盘大小颜色样式等等，方法简单-vc dial production, to adjust the dial size color style, simple method

Qt5.7.0 2D绘图.表盘时钟+数字时钟 有比较详细的注释 其他功能:允许选择表针颜色（和刻度对应） 选择表盘字体字号 -. Qt5.7.0 2D graphics digital clock dial clock+ a more detailed notes Additional features: Allows you to the color of the hands (and the corresponding scale) dial font size
