Unsolved QRenderCapture help
I create a 3D image in my GUI that look something like this:
I create it like this
Qt3DExtras::Qt3DWindow *view = new Qt3DExtras::Qt3DWindow(); view->defaultFrameGraph()->setClearColor(QColor(QRgb(0x4d4d4f))); QWidget *container = QWidget::createWindowContainer(view); Qt3DCore::QEntity *rootEntity = new Qt3DCore::QEntity();
Then I add camera, light and objects to the rootEntity and add the root to the view. As you can see from the image, it works ok.
Now I would like to save the image to a png file (preferable with the black background as transparent if possible).
I found that QRenderCapture might be the way to go, and found the following example:
However, when I try to implement it, the reply never completes.
I also tried to save the container widget as an image, but then i only get the black background.
Do anyone know how to save the 3D rendered image to a png file?

Do you need a 'screenshot' ?
A screenshot could work, but it should only be of the 3D image part of my GUI. Also I guess if I use a screen shot, I can't make the black background transparent?
Furthermore I would like to get the image, without showing it in the GUI. I mean render the 3D part, but not showing it to the user. Don't know if that is even possible
