while(1)

brush.setColor(Qt::blue);
p.setBrush(brush);
// p.drawRect((i+1)*20,(j+1)*20,80,80);//zheng fang xing
// p.drawRect((i+1)*20,(j+1)*20,40,160);//chang fang xing

//p.drawRect();
//p.drawEllipse(QPoint((i + 1) * 40, (j + 1) * 40), 15, 15);

鼠标响应：
void Widget::mousePressEvent(QMouseEvent * e)
{
/*
setWindowTitle(QString::number(e->x()) +
" " +
QString::number(e->y()));
*/
int x, y;
if(e->x() >= 20 && e->x() < 620 && e->y() >= 20 && e->y() < 620)

{
a[x][y] = player++ % 2 + 1;
}
if(isWin(x, y))
{
update();
setEnabled(false);
}
}

}
判断输赢：
bool Widget::isWin(int x, int y)
{
return f1(x, y) || f2(x, y) || f3(x, y) || f4(x ,y);
}
判断四个边界：
