画图是用那种鼠标好一点

光电还是机械

如果想做专业画图的话,用鼠标是不行的,应该用手写板来代替.

应该用 轨迹球

上学的时候写过，不过不在公司的电脑里面。呵呵，回去想到了给你…… packageguitest.myboard; importjava.awt.*; importjava.awt.event.*; importjava.awt.geom.*; importjava.io.*; importjava.util.*; importjavax.swing.*; //thepoint //impresstheinfoofonepoint,thexandy classonepointimplementsserializable{ intx;

想专业一点还是用手写板比较方便 我个人认为 机械<光电<激光

画图专业鼠标就是球在上面的那种

微软的极动鼠标非常适合！
