本程序是基于mini2440的逻辑开发文件，可以实现LCD屏的显示功能，可显示矩形、任意16位色 320*240大小的图片-This procedure is based on the logic of development mini2440 file, the LCD screen can display, can display a rectangle, any 16-bit color 320* 240 size image

把Form切割成你要的形狀，不再是死板板的長方形囉-Form cut into the shape you want, is no longer a rectangle of Si Banban Hello

使用qt.4.7.0进行画矩形，就是利用鼠标动态的画矩形，带缓冲的画矩形。(The use of qt.4.7.0 for painting rectangles, that is, the use of the mouse dynamic drawing rectangle, with a buffer painting rectangle.)
