linux QT下的别踩白方块

实现功能：完全模拟别踩白方块游戏模式，可以显示最高得分。
1、界面为4*4，一行中只有一个黑块，使用qrand 函数，采用时间种子保证每次产生
的随机数不同，再将随机数对4取余来作为黑块的位置。
2、初始时间设定值为30，通过定时器每100ms发出一次信号，刷新时间。
3、通过工厂模式，完成对黑块和白块的生产，并采用 queue 队列容器来储存块。
4、当玩家点击黑块时，delete 队头的 4 个块并 pop 弹出，在加入 4 个新块，最后将
队列中所有的块 Y 坐标增加。

部分示例代码：
block.cpp

#include "block.h"Block::Block(QWidget *parent) : QWidget(parent)
{resize(80,120);
}
WhiteBlock::WhiteBlock(QWidget *parent) : Block(parent)
{this->setStyleSheet("background-color:white;");//或者使用重绘事件  画背景图
}
BlueBlock::BlueBlock(QWidget *parent) : Block(parent)
{this->setStyleSheet("background-color:black;");
}
