Maybe you can try this wierd way, that is move the QWidget in the dock widget area to the title bar.

I modify the demo in folder

C:\Qt\Qt5.12.9\Examples\Qt-5.12.9\widgets\mainwindows\dockwidgets

to show how it works:

In "void MainWindow::createDockWindows()"

QDockWidget *dock = new QDockWidget(tr("Customers"), this);
dock->setAllowedAreas(Qt::LeftDockWidgetArea | Qt::RightDockWidgetArea);

//make a panel to hold your widgets
QWidget *p = new QWidget(dock);
QVBoxLayout *l = new QVBoxLayout(p);
p->setLayout(l);
customerList = new QListWidget(p);
l->addWidget(customerList);

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(new QWidget());//hide the real dock area
dock->setTitleBarWidget(p); //use the titlebar erea to show the content

The demo:

Drag the edge of the panel to move, actually you can drag the empty area (no child widget area). The widget on this panel still functional properly.
