详细描述
Basic touch display based input handler.
QTouch3DInputHandler is the basic input handler for touch screen devices.
Default touch input handler has the following functionalty:
| Gesture | Action |
|---|---|
| Touch-And-Move | Rotate graph within limits set for Q3DCamera |
| Tap | Select the item tapped or remove selection if none. May open the secondary view depending on the selection mode. |
| Tap-And-Hold | Same as tap. |
| Pinch | Zoom in/out within the allowable zoom range set for Q3DCamera. |
| Tap on the primary view when the secondary view is visible | Closes the secondary view. Note: Secondary view is available only for Q3DBars and Q3DSurface graphs. |
Rotation, zoom, and selection can each be individually disabled using corresponding Q3DInputHandler properties.

QTouch3DInputHandler::QTouch3DInputHandler(QObject *parent = Q_NULLPTR)
Constructs the basic touch display input handler. An optional parent parameter can be given and is then passed to QObject constructor.
[virtual] QTouch3DInputHandler::~QTouch3DInputHandler()
Destroys the input handler.
[virtual] void QTouch3DInputHandler::touchEvent(QTouchEvent *event)
Reimplemented from QAbstract3DInputHandler::touchEvent().
Override this to change handling of touch events. Touch event is given in the event.
