Remarks

The window object is used to retrieve information about the state of the window. It also is used to gain access to the document in the window, to the events that occur in the window, and to features of the browser that affect the window.

Typically, the browser creates one window object when it opens an HTML document. However, if a document defines one or more frames—that is, contains one or more frame or iframe tags—the browser creates one window object for the original document and one additional window object for each frame.

These additional objects are child windows of the original window and can be affected by actions that occur in the original. For example, closing the original window causes all child windows to close. You can also create new windows and corresponding window objects by using methods such as IHTMLWindow2::open and IHTMLWindow2::showModalDialog.

This interface may also be referred to in code as IOmWindow2.
