As OpenGL is not necessarily the default rendering backend anymore in Qt 6.x (it is Metal on macOS and Direct3D on Windows, for example), it is necessary to define the rendering backend explicitly either on your environment variables, or in your application main. It can be defined by adding
qputenv("QSG_RHI_BACKEND", "opengl");
in the beginning of your main function.
Some platforms like Android and WinRT cannot handle multiple native windows properly, so only the Qt Quick graphs are available in practice for those platforms.
Surfaces with non-straight rows and columns do not always render properly.
Changing most of
Q3DScene
properties affecting subviewports currently has no effect.
Widget based examples layout incorrectly in iOS.
Reparenting a graph to an item in another
QQuickWindow
不支持。
Android builds of QML applications importing
QtDataVisualization
also require "QT += datavisualization" in the pro file. This is because Qt Data Visualization QML plugin has a dependency to Qt Data Visualization C++ library, which Qt Creator doesn't automatically add to the deployment package.
