Qt课程设计说明书题目: Flow Free游戏设计院系：清华大学计算机系专业班级：计算机系计43班学号：2014011327学生姓名：冀伟清2015年8月目录功能需求..................... 错误！未定义书签。
界面要求. (3)设计分析 (4)功能需求：实现基于Qt的桌面版Flow Free游戏只要求实现基本的Regular Pack，不要求Bridges Pack等复杂类型以鼠标左键长按代替手机触屏操作，进行连线与原游戏相似，鼠标左键长按状态下，鼠标所在位置以圆形标示与原游戏相似，要求水流通道连通时或管道破裂时，播放声音提示（自行选择提示音）要求至少包括5⨯5、6⨯6、7⨯7的棋盘布局，每种布局至少包括两关（关卡可以从原游戏中任意选择）与原游戏相似，至少包括3个功能按钮，分别为重新开始、上一关、下一关。
界面要求Flow free游戏的游戏界面包括背景图片、工具栏图片、菜单栏等等。
导入位图以及菜单工具条后，游戏未开始前（win10系统下）的界面显示如图所示设计分析根据分析，这个程序一共要实现如下几个功能，包括5X5模式、6X6模式以及7X7模式，游戏帮助提示。
具体的结构如下程序分析程序界面：主窗口设计：行为设计：void game::createActions(){//5X5fiveAction=new
