There are cases when iOS sends one or more NSTouchPhaseMoved for a given touch event, in between NSTouchPhaseBegan and NSTouchPhaseEnded , even if the initial event location didn't change.
By default, all these events are emulated as mouse enter/down, drag and up/exit events. However, when the user taps quickly or even holds steady on a cell, if these touch moved events are generated and sent as mouse drag events, the cell selection fails, as the flag `latePress` used in [CellBehaviorBase](https://github.com/openjdk/jfx/blob/master/modules/javafx.controls/src/main/java/com/sun/javafx/scene/control/behavior/CellBehaviorBase.java#L191) is set to false, preventing the cell selection that should happen upon touch release event. This PR prevents emulating mouse drag events when the touch event doesn't change its location. ------------- Commit messages: - Don’t emulate as mouse drag events touch moved events if location didn’t change Changes: https://git.openjdk.java.net/jfx/pull/181/files Webrev: https://webrevs.openjdk.java.net/jfx/181/webrev.00 Issue: https://bugs.openjdk.java.net/browse/JDK-8242577 Stats: 8 lines in 2 files changed: 7 ins; 0 del; 1 mod Patch: https://git.openjdk.java.net/jfx/pull/181.diff Fetch: git fetch https://git.openjdk.java.net/jfx pull/181/head:pull/181 PR: https://git.openjdk.java.net/jfx/pull/181
