【M4开发板Hanker试用狂】ddllxxrr之八：动画加触摸 [复制链接]

这次就是上篇的完善。我在上次基础上加了触摸屏。

就是一个回调函数。

long touchover(unsigned long ulMessage,long lX, long lY)
{
unsigned int count=0;
unsigned int count2=0;

if(ulMessage!=TS_MSG_PTR_DOWN) return ulMessage;
if((lX>70)&&(lX<220))
{
   if((lY>140)&&(lY<290))
   {

      GrImageDraw(&sContext,lady,0,0);
      for(count2=0;count2<500;count2++)
      {
      for(count=0;count<65530;count++);
      for(count=0;count<65530;count++);
      for(count=0;count<65530;count++);
      }
      sRect.sXMin = 0;
               sRect.sYMin = 0;
               sRect.sXMax = 240;
               sRect.sYMax = 320;
               GrContextForegroundSet(&sContext, ClrWhite);
               GrRectFill(&sContext, &sRect);

               // Initialize the graphics context.
            hal_display_heading("Please hit me!!!");

   }
}
return ulMessage;
}
