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.
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.
[override virtual] void QTouch3DInputHandler::touchEvent(QTouchEvent
*event)Reimplements: QAbstract3DInputHandler::touchEvent(QTouchEvent *event).
Override this to change handling of touch events. Touch event is given in the event.
