过程来实现大部分的功能实现源码，非常经典…

代码说明：

这个程序源码实现了mapx的绝大部分功能，非常经典！！并且我增加了一个重要功能，网上有许多人提出了这个功能，但是没有很好的解决。修改后，可以实现图层的动态移动，在创建折线时，当鼠标位于窗口边缘时，图幅自动平移，就像mapinfo一模一样的效果，并非简单的移动视图中心。当然你可以根据需要将功能扩充到在画直线、画多义线、画多边形的时候实现动态移动。具体功能与说明请下载后参阅ReadMeFirst。-the process to achieve the source of most of the functionality MapX, very classic! ! And I added an important function, the Internet has made many of the features, but not a very good solution. After revisions, the layer can be achieved for the dynamic movement, in the creation of dogleg, when the mouse is located at the edge of the window, maps automatic translation, like MapInfo exactly the same effect, is not a simple mobile View Center. Of course, you may need to expand the functions of the painting straight line paintings, the paintings polygon Dynamic Mobile.
