Touch Events

Touch events compatibility and emulation.

Wisej supports all touch events on mobile and touch devices, and it simulates most of the touch events on desktop non-touch devices.

The biggest advantage of being able to use the same events on any device, regardless of their touch-hardware, is to reduce the complexity of the code and handle only one set of events.

Supported events

Wisej supports the following touch events:

• Tap. Fired when a pointer taps on the screen.

• LongTap. Fired when a pointer holds on the screen.

• Pinch. Fired when two fingers moved away or toward each other.

• Swipe. Fired when a pointed swiped over the screen.

• Track. Fired when a pointer grabs a control and moves over it.

• TouchStart. Fired when a touch point is placed on the screen.

• TouchMove. Fired when a touch point is moved over the screen.

• TouchEnd. Fired when a touch point is removed from the screen.

• TouchCancel. Fired when a touch point is canceled by the implementation. For example, if a new item is created on top of the surface that fired TouchStart.

Event handling for these events is activated only if there is an event handler attached. See Lazy Events.
