Refactor of Press and additional regression coverage.
The logic for "start", "move", "end", and "cancel" events is consolidated into a single block to reduce duplication and improve consistency of the UX across input-types. Also reduces code size.
The bailout logic for anchor tags is removed since we preventDefault for click by default. We can discuss scenarios where it makes sense to limit functionality around interactions on anchor tags.
The logic for ignoring emulated events is simplified and improved. Pointer events can produce emulated touch (immediately after pointer) and mouse events (delayed) which is now accounted for and tested.
This patch makes a change to the Focus module so that it only reports
focus/blur on the host node that's a direct child of the event component. This
brings the expected behaviour in line with the browser default of focus/blur
events not bubbling for Pressable.
The Pointer Events spec mentions that the value of `button` in a nativeEvent
can be anything between 0 and 5 for "down" events. We only care about those
with a value of 0.
1. Fix hiding context menu for longpress via touch.
2. Fix scrolling of viewport for longpress via spacebar key.
3. Add tests for anchor-related behaviour and preventDefault.
4. Add a deactivation delay for forced activation
5. Add pointerType to Press events.
NOTE: this currently extends pointerType to include `keyboard`.
NOTE: React Native doesn't have a deactivation delay for forced activation, but this is possibly because of the async bridge meaning that the events aren't dispatched sync.
This implementation differs from equivalents in React Native in the following ways:
1. A move during a press will not cancel onLongPress.
2. A move to outside the retention target will cancel the press and not
reactivate when moved back within the retention target.
* Add HoverProps type
* Add more Hover event module tests
* Add more Press event module tests
* Change default longPress delay from 1000 to 500
* Rename dispatchPressEvent -> dispatchEvent
* Consolidate state updates in Press event module
* Add keyboard support for Press events
* Add FocusProps type and unit tests
* Add Press responder event tests
Behavior being tested takes cues from React Native's Pressability.
A couple of these tests fail and require the Press implementation to be patched.
* Add PressProps type to event module
* Move default Press event delays to constants
* Fix right-click press check for Safari
* Prettier and Linter
* Use event.key in press responder
event.keyCode is a deprecated API
* Remove unused props from Press event module
Note: this is for an experimental event API that we're testing out internally at Facebook.
* onPressIn -> onPressStart
* onPressOut -> onPressEnd
* longPressCancelsPress -> onLongPressShouldCancelPress
Make sure that `onPressChange` is only called if `longPressCancelsPress` is `false`.
And make sure that `onLongPressChange` is called when a long press ends.
The 'longpress' event is dispatched during a press interaction, rather than
after it has ended.
The 'longPressCancelsPress' prop can be used to prevent 'press' being
dispatched if 'longpress' has already been dispatched.
