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

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

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

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

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

Returns the id of the hit region affected by the event. If no hit region is affected, null is returned.

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

The X coordinate of the mouse pointer in global (screen) coordinates.

The Y coordinate of the mouse pointer in global (screen) coordinates.

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

Is a Boolean indicating whether the bubbling of the event has been canceled or not.

Returns a long with details about the event, depending on the event type.

Returns a Boolean indicating whether the event produced a key character or not.

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

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

Returns the horizontal coordinate of the event relative to the whole document.

Returns the vertical coordinate of the event relative to the whole document.

Returns a WindowProxy that contains the view that generated the event.

Returns the numeric keyCode of the key pressed, or the character code (charCode) for an alphanumeric key pressed.

A Boolean indicating whether the event bubbles up through the DOM or not.

A Boolean indicating whether the event is cancelable.

A reference to the currently registered target for the event. This is the object to which the event is currently slated to be sent to; it's possible this has been changed along the way through retargeting.

Indicates whether or not event.preventDefault() has been called on the event.

Indicates which phase of the event flow is being processed.

The explicit original target of the event (Mozilla-specific).

Indicates whether or not the event was initiated by the browser (after a user click for instance) or by a script (using an event creation method, like event.initEvent)

The original target of the event, before any retargetings (Mozilla-specific).

A reference to the target to which the event was originally dispatched.

The time at which the event was created, in milliseconds. By specification, this value is time since epoch, but in reality browsers' definitions vary; in addition, work is underway to change this to be a DOMHighResTimeStamp instead.

The name of the event (case-insensitive).

Returns the current state of the specified modifier key. See the KeyboardEvent.getModifierState() for details.

Initializes the value of a MouseEvent created. If the event has already being dispatched, this method does nothing.

Initializes a UIEvent object. If the event has already being dispatched, this method does nothing.

Non-standard. Returns the value of Event.defaultPrevented. Use Event.defaultPrevented instead.

Initializes the value of an Event created. If the event has already being dispatched, this method does nothing.

Cancels the event (if it is cancelable).

For this particular event, no other listener will be called. Neither those attached on the same element, nor those attached on elements which will be traversed later (in capture phase, for instance)

Stops the propagation of events further along in the DOM.
