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"));}//SubControlAction继承QWidgetAction,下面是.h文件#ifndef SUBCONTROLACTION_H#define SUBCONTROLACTION_H#include
