Non-persistent stateful ad hoc checkbox selection

摘要

Non-persistent, stateful ad hoc checkbox selection including detecting a touch event on a first checkbox; toggling the status of the first checkbox to a new status; detecting a first drag event for at least one additional checkbox onto which a user drags the pointer, including setting a drag status of the additional checkbox indicating that the additional checkbox has experienced a drag event; statefully toggling, to the new selection status of the first checkbox, the status of the additional touch box for which a first drag event is detected; detecting a subsequent drag event for at least one additional checkbox onto which a user drags the pointer more than once during a click-and-drag operation; and statefully toggling the selection status of the additional checkbox for which a subsequent drag event is detected to the opposite of the selection status of the additional checkbox when the additional drag event is detected.
