Teechart绘图应用实例（随机线条、动态画线、画圆）(Teechart drawing application examples (random lines, dynamic draw lines, circle))

实现从SDK到MFC的封装 增加了绘制线条 矩形 椭圆等功能 而且可以变换颜色(none sdk to mfc)

MFC 画出简单的坐标 并通过按钮产生随机点坐标（横坐标逐渐增大纵坐标随机）存入文件中 另一按钮实现读出数据并将点连成折线(MFC drawing simple coordinate and through the button generates random point coordinates (abscissa increases ordinate random) into a file and another button to achieve read data points connected into line)

图形学上机程序，利用种子填充和扫描线算法实验区域的填充。有助于学习者掌握填充算法。进一步理解和学习图形学。(Graphics on procedures, the use of seed filling and scan line algorithm experimental area fill. Help learners fill algorithm. Further understanding and learning graphics.)

简单的图形学SRGP教学包运用实现。 A．实现一个下拉菜单软件包，其高层设计见2.2.6节、2.3.1节、2.3.3节中的代码段。软件包通过从输入文件读入字符串来初始化菜单条和菜单体。程序可以通过关闭菜单条使标题消失，也可以激活一个菜单（以各菜单标题在菜单条上的水平位置作为参数）来使菜单出现。 (Simple graphics SRGP realize the use of teaching packages. A. The realization of a drop-down menu package, and its high-level design, see section 2.2.6, section 2.3.1, section 2.3.3 of the code segment. Package from the input file is read into the string to initialize the menu and menu body. Procedures can be closed so that the title menu disappear, but also can activate a menu (in the menu heading in the menu bar on the horizontal position as a parameter) to make the menu appear.)

说明：  几个常用的visio模具，想用的下载来用吧(Several commonly used Visio molds. Download them if you want to use them)
