\class Qt3DInput::QAbstractPhysicalDeviceProxy
\inmodule Qt3DInput
\brief Qt3DInput::QAbstractPhysicalDeviceProxy acts as a proxy
for an actual Qt3DInput::QQAbstractPhysicalDevice device.
Qt3DInput::QAbstractPhysicalDeviceProxy can be used to facilitate
exposing a physical device to users. It alleviates the need to introspect
the axis and buttons based on their names.
It is typcally used through subclassing allowing to set the device name and
defining enums for the various axis and buttons of your targeted device.
At runtime, the status property will be updated to reflect whether an
actual device matching the device name could be created.
\since 5.8
