用Qt模仿酷我音乐盒写的个性菜单
闲来无事，发现酷我音乐盒的托盘弹出菜单蛮有个性的，于是就按照原样写了个，素材什么的都从网上下的，供大家学习，主要是它的第一项为一个Widget，而Qt的菜单项为QAction，而且这个QAction还不继承于QWidget，后来发现了有个QWidgetAction，这里可以添加自己的Widget，关键要实现一个createWidget()的虚函数。
//菜单初始化
void QMenuTest::contentMenuInit()
{
m_pContentMenu = new QMenu(this);
Q_ASSERT(m_pContentMenu);
SubControlAction* pControlAction = new SubControlAction(m_pContentMenu);
m_pContentMenu->addAction(pControlAction);
m_pContentMenu->addSeparator();
QMenu* pModelMenu = new QMenu(m_pContentMenu);
pModelMenu->addAction(tr("单曲播放"));
pModelMenu->addAction(tr("单曲循环"));
pModelMenu->addAction(tr("顺序播放"));
pModelMenu->addAction(tr("循环播放"));
pModelMenu->addAction(tr("随机播放"));
pModelMenu->setIcon(QIcon(":/res/Resources/model.png"));
pModelMenu->setTitle(tr("播放模式"));
m_pContentMenu->addMenu(pModelMenu);
m_pContentMenu->addAction(tr("显示桌面歌词"));
m_pContentMenu->addAction(tr("显示音乐树"));
m_pContentMenu->addAction(QIcon(tr(":/res/Resources/setting.png")),tr("设置"));
m_pContentMenu->addAction(QIcon(tr(":/res/Resources/exit.png")),tr("退出"));
}
