Qt QDockWidget 重叠方法

效果图片如下：

代码如下：

void MainWindow::createDockWindows()

{
    QDockWidget *dock = new QDockWidget(tr("Customers"), this);

    dock->setAllowedAreas(Qt::LeftDockWidgetArea | Qt::RightDockWidgetArea);

    customerList = new QListWidget(dock);

    customerList->addItems(QStringList()

            << "John Doe, Harmony Enterprises, 12 Lakeside, Ambleton"

            << "Jane Doe, Memorabilia, 23 Watersedge, Beaton"

            << "Tammy Shea, Tiblanka, 38 Sea Views, Carlton"

            << "Tim Sheen, Caraba Gifts, 48 Ocean Way, Deal"

            << "Sol Harvey, Chicos Coffee, 53 New Springs, Eccleston"

            << "Sally Hobart, Tiroli Tea, 67 Long River, Fedula");

    dock->setWidget(customerList);

    addDockWidget(Qt::RightDockWidgetArea, dock);

    viewMenu->addAction(dock->toggleViewAction());

 

    QDockWidget * dock1 = new QDockWidget(tr("Paragraphs"), this);

    paragraphsList = new QListWidget(dock1);

    paragraphsList->addItems(QStringList()

            << "1"

            << "2 "

            << "4"

            << "5"

            << "6"

            << "7");

    dock1->setWidget(paragraphsList);

    addDockWidget(Qt::RightDockWidgetArea, dock1);

    viewMenu->addAction(dock1->toggleViewAction());

 

    tabifyDockWidget(dock, dock1);

    QDockWidget *dock2 = new QDockWidget(tr("Paragraphs"), this);

    addDockWidget(Qt::RightDockWidgetArea, dock2);

    viewMenu->addAction(dock2->toggleViewAction());

 

    tabifyDockWidget(dock1, dock2);

    QDockWidget *dock3 = new QDockWidget(tr("whb"), this);

    addDockWidget(Qt::RightDockWidgetArea, dock3);

    viewMenu->addAction(dock3->toggleViewAction());



    tabifyDockWidget(dock2, dock3);

    dock->raise();

 

    connect(customerList, SIGNAL(currentTextChanged(QString)),

            this, SLOT(insertCustomer(QString)));

    connect(paragraphsList, SIGNAL(currentTextChanged(QString)),

            this, SLOT(addParagraph(QString)));

}
