所以大家學(xué)習(xí)程序時(shí)，一定要能從長篇的程序中找出精華，并及時(shí)拷貝下來做積累，最終能夠靈活的應(yīng)用！！

這篇文章或許是關(guān)于TFT的最后一遍文章了！再有也只是TFT的應(yīng)用程序！

只要大家能掌握之前的幾篇文章，就可以自己靈活的應(yīng)用了！?。?img onload="if(this.width>620)this.width=620;" onclick="window.open(this.src)" style="cursor:pointer" real_src="http://editerupload.eepw.com.cn/fetch/20161101/321647_1_0.jpg" src="http://editerupload.eepw.com.cn/fetch/20161101/321647_1_0.jpg" type="face" />
