- 基于X-window/motif编程实现的画图程序,程序很简单,实现了橡皮筋技术-X-window/motif Programming Based on the drawing procedure, the procedure is very simple, the realization of a rubber band technology
Circle
- 本程序实现的功能: 生成一个网格图,在网格中绘制圆,圆的圆心位置和半径可由对话框给定,网格的密度要能根据圆的直径大小而改变;也左键可用鼠标在屏幕上单击确定圆心,并拖动橡皮筋再单击鼠标右键确定半径大小。 具体操作说明: 菜单中的“绘图”菜单下有两个子菜单,分别为“鼠标交互”和“对话框设置”子菜单。 点击“鼠标交互”,即可用鼠标在窗口中画圆,鼠标左键按下的位置为圆心,采用橡皮筋画法,当拖动鼠标时,可看到圆也跟随变化,当再按下鼠标右键时即得到半径,从而绘制出圆形; 也可采用对话框设
