Element: webkitmouseforcedown event
===================================

**Non-standard:** This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

After a `mousedown` event has been fired at the element, if and when sufficient pressure has been applied to the mouse or trackpad button to qualify as a "force click," Safari begins sending **`webkitmouseforcedown`** events to the element.

**`webkitmouseforcedown`** is a proprietary, WebKit-specific event. It is part of the `Force Touch Events` feature.

Syntax
------

Use the event name in methods like `addEventListener()`, or set an event handler property.


```js
addEventListener("webkitmouseforcedown", (event) => {});

onwebkitmouseforcedown = (event) => {};
```

Event type
----------

A `MouseEvent`. Inherits from `UIEvent` and `Event`.

UIEvent

MouseEventEvent properties
----------------

*This interface also inherits properties of its parents, `UIEvent` and `Event`.*

`MouseEvent.altKey` Read only 

Returns `true` if the `alt` key was down when the mouse event was fired.

`MouseEvent.button` Read only 

The button number that was pressed (if applicable) when the mouse event was fired.

`MouseEvent.buttons` Read only 

The buttons being pressed (if any) when the mouse event was fired.

`MouseEvent.clientX` Read only 

The X coordinate of the mouse pointer in viewport coordinates.

`MouseEvent.clientY` Read only 

The Y coordinate of the mouse pointer in viewport coordinates.

`MouseEvent.ctrlKey` Read only 

Returns `true` if the `control` key was down when the mouse event was fired.

`MouseEvent.layerX` 
Non-standard
 Read only 

Returns the horizontal coordinate of the event relative to the current layer.

`MouseEvent.layerY` 
Non-standard
 Read only 

Returns the vertical coordinate of the event relative to the current layer.

`MouseEvent.metaKey` Read only 

Returns `true` if the `meta` key was down when the mouse event was fired.

`MouseEvent.movementX` Read only 

The X coordinate of the mouse pointer relative to the position of the last `mousemove` event.

`MouseEvent.movementY` Read only 

The Y coordinate of the mouse pointer relative to the position of the last `mousemove` event.

`MouseEvent.offsetX` Read only 

The X coordinate of the mouse pointer relative to the position of the padding edge of the target node.

`MouseEvent.offsetY` Read only 

The Y coordinate of the mouse pointer relative to the position of the padding edge of the target node.

`MouseEvent.pageX` Read only 

The X coordinate of the mouse pointer relative to the whole document.

`MouseEvent.pageY` Read only 

The Y coordinate of the mouse pointer relative to the whole document.

`MouseEvent.relatedTarget` Read only 

The secondary target for the event, if there is one.

`MouseEvent.screenX` Read only 

The X coordinate of the mouse pointer in screen coordinates.

`MouseEvent.screenY` Read only 

The Y coordinate of the mouse pointer in screen coordinates.

`MouseEvent.shiftKey` Read only 

Returns `true` if the `shift` key was down when the mouse event was fired.

`MouseEvent.mozInputSource` 
Non-standard
 Read only 

 The type of device that generated the event (one of the `MOZ_SOURCE_*` constants).
 This lets you, for example, determine whether a mouse event was generated by an actual mouse or by a touch event (which might affect the degree of accuracy with which you interpret the coordinates associated with the event).


`MouseEvent.webkitForce` 
Non-standard
 Read only 

The amount of pressure applied when clicking.

`MouseEvent.x` Read only 

Alias for `MouseEvent.clientX`.

`MouseEvent.y` Read only 

Alias for `MouseEvent.clientY`.
