# MouseEvent

Extends `Event`

The MouseEvent object is received by the `Item`’s mouse event handlers `item.onMouseDown`, `item.onMouseDrag`, `item.onMouseMove`, `item.onMouseUp`, `item.onClick`, `item.onDoubleClick`, `item.onMouseEnter` and `item.onMouseLeave`. The MouseEvent object is the only parameter passed to these functions and contains information about the mouse event.

## Properties

`type`

The type of mouse event.

#### Values:

- `'mousedown'`, `'mouseup'`, `'mousedrag'`, `'click'`, `'doubleclick'`, `'mousemove'`, `'mouseenter'`, `'mouseleave'`

#### Type:

- `String`

`point`

The position of the mouse in project coordinates when the event was fired.

#### Type:

- `Point`

`target`

The item that dispatched the event. It is different from `currentTarget` when the event handler is called during the bubbling phase of the event.

#### Type:

- `Item`

`currentTarget`

The current target for the event, as the event traverses the scene graph. It always refers to the element the event handler has been attached to as opposed to `target` which identifies the element on which the event occurred.

#### Type:

- `Item`

`delta`

#### Type:

- `Point`

## Methods inherited from `Event`

`preventDefault()`

Cancels the event if it is cancelable, without stopping further propagation of the event.

`stopPropagation()`

Prevents further propagation of the current event.

`stop()`

Cancels the event if it is cancelable, and stops stopping further propagation of the event. This is has the same effect as calling both `stopPropagation`() and `preventDefault`().

Any handler can also return `false` to indicate that `stop()` should be called right after.
