p = libpointer(DataType,Value)creates pointer initialized to a copy ofValue. Examples collapse all Create NULL Pointer for string Argument p = libpointer('string'); Input Arguments collapse all DataType—Type of pointer character vector
The input events that represent gestures (such asTappedorDoubleTapped) are usually only fired after a pointer is released, so you shouldn't attempt to capture a pointer in event handlers for gesture events. ThePointerreference in event data for gesture events won't be permitted to initiate...

Other functional languages, such as Haskell and Scala, take a different view. Haskell includes aMaybetype, which essentially encapsulates an optional value. A value of typeMaybecan contain either a value of a given type or nothing. There is no concept of a null reference. Scala has a similar...
If the event argument doesn't intrinsically expose the pointer details required by your app, you can get access to extended pointer data through theGetCurrentPointandGetIntermediatePointsmethods ofPointerRoutedEventArgs. We recommend using these methods as you can specify the context of the pointer ...
