Tabify 3 QDockWidget

Question

如何在QMainWindow中为3个小部件创建一个列表化底座？

我正在使用下面的代码：

widget1 = new QDockWidget(this);
widget1 ->setObjectName("name1");
addDockWidget(Qt::LeftDockWidgetArea, widget1);
widget2 = new QDockWidget(this);
widget2 ->setObjectName("name2");
addDockWidget(Qt::LeftDockWidgetArea, widget2);
tabifyDockWidget(widget2, widget1);
widget3 = new QDockWidget(this);
widget3->setObjectName("name3");
addDockWidget(Qt::LeftDockWidgetArea, widget3);
tabifyDockWidget(widget3, widget1);

此代码产生两个停靠点：Dock 2，Dock 1和Dock 3。

要修复，我只需更改第一个和第二个参数的位置：

widget1 = new QDockWidget(this);
widget1 ->setObjectName("name1");
addDockWidget(Qt::LeftDockWidgetArea, widget1);

widget2 = new QDockWidget(this);
widget2 ->setObjectName("name2");
addDockWidget(Qt::LeftDockWidgetArea, widget2);
tabifyDockWidget(widget2, widget1);

widget3 = new QDockWidget(this);
widget3->setObjectName("name3");
addDockWidget(Qt::LeftDockWidgetArea, widget3);
tabifyDockWidget(widget1, widget3);
