          }
   catch(Exception e){  }
   }
   }
     }
} 以上程序运行后,在小程序窗口就会不断的滚动显示字"一"到"十"
我想当我在窗口里点击一下,那么就让显示的字停下来(一直到我再次点击时那字才又开始滚动显示)
且停下来后,那么显示的那个字下次就不会再显示有了
如:某时刻我点击了一下,此时窗口显示"三",然后我再点击,则又继续滚动显示字"一"到"十",但此时"三"已不在其中了如果我再点一下又停下来,此时如果显示"六",那么我接着再点击又继续显示,但"三"和"六"又删掉了依此类推,循环点击,直到所有的字删完为止!请高手帮我补充完整!也可另帮写一个完整的程序!
哪个高手先帮我实现,我把100分给他!谢谢!我在线等!

Answer 4

还不太详细 ，把 if(isstarte==true) return; 加在isstarte=!isstarte;的下面就详细了。
