Question

I´am trying to create my own custom list component in a Flex mobile Project which fires an Event when the user touches a listitem and holds the finger down for a given time.
Some kind of “longTouch”-Event like its implemented on native android listitems to edit the entry for example.

I tried to listen for the MOUSE_DOWN Event to start a timer and dispatch an event when the timer finished. But this approach failed because i cant get the listitem that was pressed by the user because the List component updates the “selectedItem”-property only after the user lifts his finger from the list.

thanks in advance

There is no longTouch (or longPress) event exposed through the Flash Player Native APIs.

One option is to roll your own using TOUCH_BEGIN, TOUCH_END, and a timer.

Basically:

1. When user starts the touch, start the timer.

2. When the touch_End event fires; check the timer to see how long it has been running using currentCount. If it is long enough to be considered a "long touch", then dispatch your custom longPress event. If not; then stop the timer and ignore.

   This could all happen inside the renderer; so you’d know exactly what item was pressed.

I expect this would be more solid than using mouse events, which seem to be inconsistent on touch based devices
