Setting Qwidget to view

[Tendy]

So right now I have a container in my ui design name CubeView https://gyazo.com/8b565295a2c34c00280c769ca7e7c8c) and I'm currently trying to set it to a Qt3DExtras::Qt3DWindow that should have a background of gray. I'm trying to do this by
w.findChild<QWidget*>("CubeView")->QWidget::createWindowContainer(view);
but it doesn't seem to be working, If anyone could thing of the proper way of doing this it would be an immense help. Thanks

@Tendy Your image is not visible?
Which version of Qt?
Which OS?
Which toolchain are you using?
Can you post a MWC sample to show how you are currently doing it?

Im using 5.10 on windows 10, with MSVC2017_64bit Here the link for the image @kenchan https://i.gyazo.com/8b565295a2c34c00280c769ca7e7c8ca.png

Here what I have so far. https://pastebin.com/i7nXKA0b. I'm just getting into Qt this week but i have prior c++ experience. From what I'm reading is that inside that CubeView container I might have to create a widget inside that but it seem redundant.

OK thanks, can you please show your .pro file and the headers section of the cpp file?

@Tendy A question, where are you setting the name "CubeView" on the QWidget w in the first place?

[Tendy]

Cube view is being set in the .ui file. Here the top of the main.cpp file
https://pastebin.com/12nGgSDx
and here's widget.cpp
https://pastebin.com/D6rZE1ch And widget.h

@Tendy
and is that widget just a simple widget?
BTW can I assume you have read all the docs for the 3dExtras? http://doc.qt.io/qt-5/qt3dextras-module.html

Along with my ui file https://pastebin.com/82ndTT0t

Just a widget I believe @kenchan and yes I've read the doc on it and the update on the createwindowcontainer

You are right about it not working the way you are doing it but it seems to work if you do something like this...

    Qt3DExtras::Qt3DWindow *view = new Qt3DExtras::Qt3DWindow();
    view->defaultFrameGraph()->setClearColor(QColor(255,0,0));
    QWidget * viewcontainer = QWidget::createWindowContainer(view);
    viewcontainer->setGeometry(container->geometry());
    container->deleteLater();
    viewcontainer->setParent(&w);

and this works

    QWidget *container = (QWidget*)w.findChild<QWidget*>("CubeView");
    QSize csize = container->size();
    QPoint cpos = container->pos();
    container = QWidget::createWindowContainer(view);
    container->setParent(0);
    container->setParent(&w);
    container->move(cpos);
    container->resize(csize);

Basically you must reparent the widget or give it a new widget after you do the creatWindowContainer thing. Also it is better to use a layout for you widgets then you can resize them all easier.
It is a bit of a hack and I don't know why it does not work the way you want to do it. Maybe someone else can tell us the answer to that :-)
