Propriétés
----------

| Property | Type | Description |
| --- | --- | --- |
| `target` Lecture seule  | `EventTarget` | The element that was underneath the element being dragged. |
| `type` Lecture seule  | `DOMString` | The type of event. |
| `bubbles` Lecture seule  | `Boolean` (en-US) | Whether the event normally bubbles or not |
| `cancelable` Lecture seule  | `Boolean` (en-US) | Whether the event is cancellable or not? |
| `view` Lecture seule  | `WindowProxy` | `document.defaultView` (`window` of the document) |
| `detail` Lecture seule  | `long` (`float`) | 0. |
| `dataTransfer` | DataTransfer | The data that underlies a drag-and-drop operation, known as the drag data store. Protected mode. |
| `currentTarget` Lecture seule  | EventTarget | The node that had the event listener attached. |
| `relatedTarget` Lecture seule  | EventTarget | For `mouseover`, `mouseout`, `mouseenter` and `mouseleave` events: the target of the complementary event (the `mouseleave` target in the case of a `mouseenter` event). `null` otherwise. |
| `screenX` Lecture seule  | long | The X coordinate of the mouse pointer in global (screen) coordinates. |
| `screenY` Lecture seule  | long | The Y coordinate of the mouse pointer in global (screen) coordinates. |
| `clientX` Lecture seule  | long | The X coordinate of the mouse pointer in local (DOM content) coordinates. |
| `clientY` Lecture seule  | long | The Y coordinate of the mouse pointer in local (DOM content) coordinates. |
| `button` Lecture seule  | unsigned short | The button number that was pressed when the mouse event was fired: Left button=0, middle button=1 (if present), right button=2. For mice configured for left handed use in which the button actions are reversed the values are instead read from right to left. |
| `buttons` Lecture seule  | unsigned short | The buttons being pressed when the mouse event was fired: Left button=1, Right button=2, Middle (wheel) button=4, 4th button (typically, "Browser Back" button)=8, 5th button (typically, "Browser Forward" button)=16. If two or more buttons are pressed, returns the logical sum of the values. E.g., if Left button and Right button are pressed, returns 3 (=1 | 2). More info. |
| `mozPressure` Lecture seule  | float | The amount of pressure applied to a touch or tabdevice when generating the event; this value ranges between 0.0 (minimum pressure) and 1.0 (maximum pressure). |
| `ctrlKey` Lecture seule  | boolean | `true` if the control key was down when the event was fired. `false` otherwise. |
| `shiftKey` Lecture seule  | boolean | `true` if the shift key was down when the event was fired. `false` otherwise. |
| `altKey` Lecture seule  | boolean | `true` if the alt key was down when the event was fired. `false` otherwise. |
| `metaKey` Lecture seule  | boolean | `true` if the meta key was down when the event was fired. `false` otherwise. |
