| |
| \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 |
