IHTMLEventObj Interface

---

This interface provides access to the event processes, such as the element in which the event occurred, the state of the keyboard keys, the location of the mouse, and the state of the mouse buttons.

IHTMLEventObj Methods

get_altKey	Retrieves the state of the ALT key.
get_button	Retrieves which mouse button, if any, is pressed.
get_cancelBubble	Retrieves the value that indicates whether the current event should bubble up the hierarchy of event handlers.
get_clientX	Retrieves the horizontal position of the mouse hit relative to the top of the client area of the window, excluding window decorations or scroll bars.
get_clientY	Retrieves the vertical position of the mouse hit relative to side of the client area of the window, excluding window decorations or scroll bars.
get_ctrlKey	Retrieves the state of the CTRL key.
get_fromElement	Retrieves the object the cursor is exiting during the onmouseover and onmouseout events.
get_keyCode	Retrieves the Unicode key code associated with the key that caused the event.
get_offsetX	Retrieves the horizontal coordinate of the mouse's position relative to the object firing the event.
get_offsetY	Retrieves the vertical coordinate of the mouse's position relative to the object firing the event.
get_qualifier	Specifies the event qualifier parameter passed with the event.
get_reason	Retrieves the disposition of data transfer for a data source object.
get_returnValue	Retrieves the return value of the event.
get_screenX	Retrieves the vertical position of the event, in pixels, relative to the user's screen.
get_screenY	Retrieves the horizontal position of the event, in pixels, relative to the user's screen.
get_shiftKey	Retrieves the state of the SHIFT key.
get_srcElement	Retrieves an interface pointer for the object in which the event occurred.
get_srcFilter	Retrieves the filter object that caused the onfilterchange event.
get_toElement	Retrieves the object being moved to for the onmouseover and onmouseout events.
get_type	Retrieves the event name as a string.
get_x	Retrieves the position of the mouse hit relative to the object in the parent hierarchy that is positioned using the cascading style sheets (CSS) positioning attribute.
get_y	Retrieves the position of the mouse hit relative to the object in the parent hierarchy that is positioned using the cascading style sheets (CSS) positioning attribute.
put_cancelBubble	Sets the value that indicates whether the current event should bubble up the hierarchy of event handlers.

Remarks

The event object is only available during an event; that is, you can use it in event handlers but not in other code. You retrieve the event object by calling the IHTMLWindow2::get_event method.

Although all event properties are available to all event objects, some properties might not have meaningful values during some events. For example, the values retrieved by the get_fromElement and the get_toElement methods are meaningful only when processing the onmouseover and onmouseout events.
