QT-右键菜单

#The QMenu class provides a menu widget for use in menu bars, context menus, and other popup menus.

支持类 QMenu，可以查帮助了解详细

注意：tableview 的右键菜单策略，选择的custom那个,
m_tableview->setContextMenuPolicy(Qt::CustomContextMenu);

void UCommWidgetTool::AddMenuItem(QMenu* menu, const QString& menuText, QObject *obj, const char* slotFunc, const QString& iconSrc)
{
    QAction *action = new QAction(menuText, menu);
    action->setIcon(QIcon(iconSrc));
    menu->addAction(action);
    QObject::connect(action, SIGNAL(triggered()), obj, slotFunc);
}

调用

void Page::Init()
{
	connect(m_tableView, SIGNAL(customContextMenuRequested(const QPoint&)), this, SLOT(OnContextMenu(const QPoint&)));
}

void Page::OnContextMenu(const QPoint& point)
{
	QMenu popMenu;
	UCommWidgetTool::AddMenuItem(&popMenu, tr("Print"), this, SLOT(OnPrintReport()), ":/history/Images/printer.png");
	//popMenu.addSeparator(); //多个菜单间隔    
    popMenu.exec(QCursor::pos());  
}
