These flags are NOT mutually exclusive (i.e., an onStateChange + * event may indicate some combination of these flags). + * + * STATE_IS_REQUEST + * This flag indicates that the state transition is for a request, which + * includes but is not limited to document requests. (See below for a + * description of document requests.) Other types of requests, such as + * requests for inline content (e.g., images and stylesheets) are + * considered normal requests. + * + * STATE_IS_DOCUMENT + * This flag indicates that the state transition is for a document request. + * This flag is set in addition to STATE_IS_REQUEST. A document request + * supports the nsIChannel interface and its loadFlags attribute includes + * the nsIChannel::LOAD_DOCUMENT_URI flag. + * + * A document request does not complete until all requests associated with + * the loading of its corresponding document have completed. This includes + * other document requests (e.g., corresponding to HTML <iframe> elements). + * The document corresponding to a document request is available via the + * DOMWindow attribute of onStateChange's aWebProgress parameter. + * + * STATE_IS_NETWORK + * This flag indicates that the state transition corresponds to the start + * or stop of activity in the indicated nsIWebProgress instance. This flag + * is accompanied by either STATE_START or STATE_STOP, and it may be + * combined with other State Type Flags. + * + * Unlike STATE_IS_WINDOW, this flag is only set when activity within the + * nsIWebProgress instance being observed starts or stops. If activity + * only occurs in a child nsIWebProgress instance, then this flag will be + * set to indicate the start and stop of that activity. + * + * For example, in the case of navigation within a single frame of a HTML + * frameset, a nsIWebProgressListener instance attached to the + * nsIWebProgress of the frameset window will receive onStateChange calls + * with the STATE_IS_NETWORK flag set to indicate the start and stop of + * said navigation. In other words, an observer of an outer window can + * determine when activity, that may be constrained to a child window or + * set of child windows, starts and stops. + * + * STATE_IS_WINDOW + * This flag indicates that the state transition corresponds to the start + * or stop of activity in the indicated nsIWebProgress instance. This flag + * is accompanied by either STATE_START or STATE_STOP, and it may be + * combined with other State Type Flags. + * + * This flag is similar to STATE_IS_DOCUMENT. However, when a document + * request completes, two onStateChange calls with STATE_STOP are + * generated. The document request is passed as aRequest to both calls. + * The first has STATE_IS_REQUEST and STATE_IS_DOCUMENT set, and the second + * has the STATE_IS_WINDOW flag set (and possibly the STATE_IS_NETWORK flag + * set as well -- see above for a description of when the STATE_IS_NETWORK + * flag may be set).
