Detailed Description
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 |
| 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. |
| 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.
