The `inputlock` event is fired after a request to acquire an input lock or
whenever the state of the canvas' input lock has changed, the latter typically
occurs because the lock was released by the user pressing the ESC key or
performing a browser-specific gesture. The `detail` property is an `Object`
with the property `pointer` containing whether the Pointer Lock is currently
held or not.
#### RFB.disconnect()
The `RFB.disconnect()` method is used to disconnect from the currently
@ -383,3 +400,24 @@ to the remote server.
**`text`**
- A `DOMString` specifying the clipboard data to send.
#### RFB.requestInputLock()
The `RFB.requestInputLock()` method is used to request that the RFB canvas hold
an input lock. An `inputlock` event will be fired with the result of the
acquisition of the requested locks.
##### Syntax
RFB.requestInputLock( { pointer: true } );
###### Parameters
**`pointer`**
- Requests to acquire a [Pointer
Lock](https://developer.mozilla.org/en-US/docs/Web/API/Pointer_Lock_API),
which hides the local mouse cursor and provides relative motion events.
This must be called directly from an event handler where a user has
directly interacted with an element through an [engagement
gesture](https://w3c.github.io/pointerlock/#dfn-engagement-gesture) (e.g. a
click or touch event) for the browser to allow this.
