    Understand Touch Gestures
    In This Topic

    Touch support requires that the widget support basic touch gestures. There are several types of touch gestures such as basic or common and pinch or stretch.

    Basic touch gestures include the following:

    Gesture Description
    Tap One finger touches the screen and lifts up.
    Press and hold One finger touches the screen and stays in place.
    Slide One or more fingers touch the screen and move in the same direction.
    Swipe One or more fingers touch the screen and move a short distance in the same direction.
    Pinch Two or more fingers touch the screen and move farther apart or closer together.
    Rotate Two or more fingers touch the screen and move in a clockwise or counter-clockwise arc.
    Switch Two or more fingers touch the screen and move farther apart.

    SpreadJS uses standard pinch and stretch gestures when zooming.
