* Pressability implements press handling capabilities.
|
||
|
|
*
|
||
|
|
* =========================== Pressability Tutorial ===========================
|
||
|
|
*
|
||
|
|
* The `Pressability` class helps you create press interactions by analyzing the
|
||
|
|
* geometry of elements and observing when another responder (e.g. ScrollView)
|
||
|
|
* has stolen the touch lock. It offers hooks for your component to provide
|
||
|
|
* interaction feedback to the user:
|
||
|
|
*
|
||
|
|
* - When a press has activated (e.g. highlight an element)
|
||
|
|
* - When a press has deactivated (e.g. un-highlight an element)
|
||
|
|
* - When a press sould trigger an action, meaning it activated and deactivated
|
||
|
|
* while within the geometry of the element without the lock being stolen.
|
||
|
|
*
|
||
|
|
* A high quality interaction isn't as simple as you might think. There should
|
||
|
|
* be a slight delay before activation. Moving your finger beyond an element's
|
||
|
|
* bounds should trigger deactivation, but moving the same finger back within an
|
||
|
|
* element's bounds should trigger reactivation.
|
||
|
|
*
|
||
|
|
* In order to use `Pressability`, do the following:
|
||
|
|
*
|
||
|
|
* 1. Instantiate `Pressability` and store it on your component's state.
|
||
|
|
*
|
||
|
|
* state = {
|
||
|
|
* pressability: new Pressability({
|
||
|
|
* // ...
|
||
|
|
* }),
|
||
|
|
* };
|
||
|
|
*
|
||
|
|
* 2. Choose the rendered component who should collect the press events. On that
|
||
|
|
* element, spread `pressability.getEventHandlers()` into its props.
|
||
|
|
*
|
||
|
|
* return (
|
||
|
|
* <View {...this.state.pressability.getEventHandlers()} />
|
||
|
|
* );
|
||
|
|
*
|
||
|
|
* 3. Reset `Pressability` when your component unmounts.
|
||
|
|
*
|
||
|
|
* componentWillUnmount() {
|
||
|
|
* this.state.pressability.reset();
|
||
|
|
* }
|
||
|
|
*
|
||
|
|
* ==================== Pressability Implementation Details ====================
|
||
|
|
*
|
||
|
|
* `Pressability` only assumes that there exists a `HitRect` node. The `PressRect`
|
||
|
|
* is an abstract box that is extended beyond the `HitRect`.
|
||
|
|
*
|
||
|
|
* # Geometry
|
||
|
|
*
|
||
|
|
* ┌────────────────────────┐
|
||
|
|
* │ ┌──────────────────┐ │ - Presses start anywhere within `HitRect`, which
|
||
|
|
* │ │ ┌────────────┐ │ │ is expanded via the prop `hitSlop`.
|
||
|
|
* │ │ │ VisualRect │ │ │
|
||
|
|
* │ │ └────────────┘ │ │ - When pressed down for sufficient amount of time
|
||
|
|
* │ │ HitRect │ │ before letting up, `VisualRect` activates for
|
||
|
|
* │ └──────────────────┘ │ as long as the press stays within `PressRect`.
|
||
|
|
* │ PressRect o │
|
||
|
|
* └────────────────────│───┘
|
||
|
|
* Out Region └────── `PressRect`, which is expanded via the prop
|
||
|
|
* `pressRectOffset`, allows presses to move
|
||
|
|
* beyond `HitRect` while maintaining activation
|
||
|
|
* and being eligible for a "press".
