Event Object Properties

The IHTMLEventObj interface contains additional information about the current event. When the onresize event is fired, you can use the IHTMLWindow2::event property to retrieve an IHTMLEventObj interface. To obtain an alternate interface pointer such as IHTMLEventObj2 or IHTMLEventObj3, call QueryInterface on the object.

Remarks

The HTMLWindowEvents::onresize event fires for block and inline objects with layout, even if document or CSS (cascading style sheets) property values are changed. Objects have layout when measurements such as the height and width attributes are set, or when the position of the object is set. Intrinsic objects, such as button, and windowed objects, such as window and iframe, fire as expected. This event does not fire for files with embedded controls.
Resizing HTML applications also fires the HTMLWindowEvents::onresize event.
