为TurboC增加一个立体按钮函数 王焱 1997-01-01   当今大多数优秀软件都采用立体按钮作选择开关,这种直观、清晰的图形界面深受广大用户的青睐,笔者利用Turbo C 2.0提供的绘图功能编制了一个通用的立体按钮函数Windows,该函数使用极其灵活,可任意改变其大小、高度、颜色及状态。现将实现立体按钮的程序介绍给读者,以供参考。   /*在主程序中调用举例*/   #include "graphics.h"   void windows(int x,int y,int xa,int ya,int high,int stat,int color);   main()   {   int d=VGA,m=VGAHI;   initgraph(&d,&m,"");   windows(100,100,200,130,4,0,1);   getch();   closegraph();}   /*立体按钮函数*/   void windows(int x,int y,int xa,int ya,int high,int stat,int color)   {register i;   if(!stat)   setfillstyle(1,color+8);else setfillstyle(1,color);   bar(x,y,xa,ya);   setcolor(0);   rectangle(x-high,y-high,xa+high,ya+high);   rectangle(x,y,xa,ya);   if(stat)   setcolor(7);else setcolor(8);   for (i=1;i<high;i++)   {line(x-i,y-i,x-i,ya+i);}   line(x-i,ya+i,xa+i,ya+i);}   if(stat)   setcolor(8);else setcolor(7);   for(i=1;i<high;i++)   {line(xa+i,y-i,xa+i,ya+i);   line(x-i,y-i,xa+i,y-i);}   setcolor(0);   line(x-high,y-high,x,y);   line(xa+high,y-high,xa,y);   line(xa+high,ya+high,xa,ya);   line(x-high,ya+high,x,ya);   }
