Some other odd behaviour with docking windows in 4.7.0 tp as per subject
are:-
1. They only dock in the pane where they were first added to the
maniwindow
2. They will not tab dock at all.
In general (4.6 as well) I cannot seem to create a tabbed docking window
startup display of the mainwindow. If I make visible other docking
windows that share a docking pane, they appear nested even if I set the
ForceTabbedDocks dock option. Is there something else I need to do?

Subject: QDeclarativeView & QGraphicsView inside a QDockWidget
When a Docking window contains a Qml Declarative (or Graphics) view and
it is dragged off the docking area, the state within
QDockWidgetPrivate::startDrag() at line 718 of qdockwidget.cpp is nulled
after the layout is unplugged in QMainWindowLayout::unplug(QWidget
*widget) at line 1798 of qmainwindowlayout.cpp.
This line calls the widgets own unplug method and
QDockWidgetPrivate::setWindowState at line 999. During this method the
docking window is hidden if it is visible at line 1021 and at this point
the previous state is nulled. This then causes an exception during the
assignment that follows the unplug at line 718.
Is this a know issue?
All I do to embed the Qml in a docking window is: -
m_scene = new QGraphicsScene;
m_scene->setSceneRect(0, 0, 400, 70);
declarativeView->setScene(m_scene);
m_engine = new QDeclarativeEngine;
m_component = new QDeclarativeComponent(m_engine);
connect(m_component,
SIGNAL(statusChanged(QDeclarativeComponent::Status)),
SLOT(statusComponent(QDeclarativeComponent::Status)));
m_component->loadUrl(QUrl::fromLocalFile("C:/samegame/SameGame.qml"));
