+/*! \enum QTouchEvent::DeviceType
+ \since 4.6
+
+ This enum represents the type of device that generated a QTouchEvent.
+
+ \value TouchScreen In this type of device, the touch surface and display are integrated. This
+ means the surface and display typically have the same size, such that there
+ is a direct relationship between the touch points' physical positions and the
+ coordinate reported by QTouchEvent::TouchPoint. As a result, Qt allows the
+ user to interact directly with multiple QWidgets and QGraphicsItems at the
+ same time.
+
+ \value TouchPad In this type of device, the touch surface is separate from the display. There
+ is not a direct relationship between the physical touch location and the
+ on-screen coordinates. Instead, they are calculated relative to the current
+ mouse position, and the user must use the touch-pad to move this reference
+ point. Unlike touch-screens, Qt allows users to only interact with a single
+ QWidget or QGraphicsItem at a time.
+*/
