从上一篇的效果可以看到窗口并不美观，而且不能用鼠标进行拖动，还不可以实现最大最小化。

要实现用鼠标拖动可以，重载鼠标点击和鼠标移动事件的处理，具体如下：

//GraphicDialog.h

protected:

void mousePressEvent(QMouseEvent *)
void mouseMoveEvent(QMouseEvent* );

private:

QPoint last;//保存鼠标按下的位置

//GraphicDialog.cpp

void GraphicDialog::mousePressEvent(QMouseEvent *e)
{
last = e->globalPos();
}

void GraphicDialog::mouseMoveEvent(QMouseEvent *e)
{
if(e->buttons()== Qt::LeftButton)
{
QPoint newpos = e->globalPos();
QPoint upleft = mapToParent(newpos - last); //计算距原位置的偏移
move(upleft);
last = newpos; //更新原位置到最新的位置
}
}
这时已经可以用鼠标手动窗口到任意位置。
