C++ 选项卡化所有dock小部件

我正在尝试创建一个菜单操作，它将在我的qMain窗口中对所有停靠点进行选项卡化，以减少混乱。在尝试使用迭代器进行一些算术运算之后，oops！，我意识到我需要使用类似于。问题是，它不会在我的应用程序中编译，因为dockPair没有初始化。我真的不太了解相邻迭代器的实现或限制，也不确定我是否做错了什么，或者它是否真的不适合我的应用程序

此外，如果有一种比我的方法更容易/更好的方法来对所有码头进行选项卡化，我可以重新实现该功能

tabify码头：

问题是，我正试图用MSVC2010编译这段代码，它是

使用normal for循环的工作代码如下：

void mainWindow::tabifyDocks()
{
    // get a list of all the docks
    QList<QDockWidget*> docks = findChildren<QDockWidget*>();

    // first, un-float all the tabs
    std::for_each(docks.begin(), docks.end(), std::bind(&QDockWidget::setFloating, std::placeholders::_1 /* the dock widget*/, false));

    // sort them into dockWidget areas
    QVector<QDockWidget*> topArea, leftArea, rightArea, bottomArea;
    QVector<QVector<QDockWidget*>*> dockAreas;

    dockAreas.push_back(&topArea);
    dockAreas.push_back(&leftArea);
    dockAreas.push_back(&rightArea);
    dockAreas.push_back(&bottomArea);

    std::for_each(docks.begin(), docks.end(), [&] (QDockWidget* dock) 
    {
        if      (dockWidgetArea(dock) ==  Qt::TopDockWidgetArea     )   {topArea.   push_back(dock);    this->removeDockWidget(dock); dock->resize(dock->minimumSizeHint());    this->addDockWidget(Qt::TopDockWidgetArea   , dock); dock->setVisible(true);}
        else if (dockWidgetArea(dock) ==  Qt::LeftDockWidgetArea    )   {leftArea.  push_back(dock);    this->removeDockWidget(dock); dock->resize(dock->minimumSizeHint());    this->addDockWidget(Qt::LeftDockWidgetArea  , dock); dock->setVisible(true);}
        else if (dockWidgetArea(dock) ==  Qt::RightDockWidgetArea   )   {rightArea. push_back(dock);    this->removeDockWidget(dock); dock->resize(dock->minimumSizeHint());    this->addDockWidget(Qt::RightDockWidgetArea , dock); dock->setVisible(true);}
        else if (dockWidgetArea(dock) ==  Qt::BottomDockWidgetArea  )   {bottomArea.push_back(dock);    this->removeDockWidget(dock); dock->resize(dock->minimumSizeHint());    this->addDockWidget(Qt::BottomDockWidgetArea, dock); dock->setVisible(true);}
    });

    // then, tab them all       
    // definition: areas == top && bottom && etc.. 
    // definition: area == top || bottom || etc...
    for (QVector<QVector<QDockWidget*>*>::iterator areasItr = dockAreas.begin(); areasItr != dockAreas.end(); areasItr++)
    {
        // within each area, tab all the docks if there are more than 1
        QVector<QDockWidget*> area = **areasItr;
        auto areaRange = make_adjacent_range(area);
        for (auto areaItr = areaRange.begin(); areaItr != areaRange.end(); ++areaItr) 
        {
            auto dockPair = *areaItr;
            this->tabifyDockWidget(dockPair.first, dockPair.second);
        }
    }
}

如果你使用像QVector这样的向量，而不是使用原始指针，那是行不通的？@danielfranca我认为最终是c++11编译器支持问题msvc2010。我认为这段代码将在支持基于范围的循环的较新版本上编译/运行。
