+ \class QSGRendererInterface
+ \brief An interface providing access to some of the graphics API specific internals
+ of the scenegraph.
+ \inmodule QtQuick
+ \since 5.8
+
+ Renderer interfaces allow accessing graphics API specific functionality in
+ the scenegraph. Such internals are not typically exposed. However, when
+ integrating custom rendering via QSGRenderNode for example, it may become
+ necessary to query certain values, for instance the graphics device (e.g.
+ the Direct3D or Vulkan device) that is used by the scenegraph.
+
+ QSGRendererInterface's functions have varying availability. API and
+ language queries, like graphicsApi() or shaderType() are always available,
+ meaning it is sufficient to construct a QQuickWindow or QQuickView, and the
+ graphics API or shading language in use can be queried right after via
+ QQuickWindow::rendererInterface(). This guarantees that utilities like the
+ GraphicsInfo QML type are able to report the correct values as early as
+ possible, without having conditional property values - depending on for
+ instance shaderType() - evaluate to unexpected values.
+
+ Engine-specific accessors, like getResource(), are however available only
+ after the scenegraph is initialized. Additionally, there may be
+ backend-specific limitations on when such functions can be called. The only
+ way that is guaranteed to succeed is calling them when the rendering of a
+ node (i.e. the preparation of the command list for the next frame) is
+ active. In practice this typically means QSGRenderNode::render().
