Please add a summary to this article.
  Last changed in Gecko 1.9 (Firefox 3)

Inherits from: nsIWebProgressListener

Method overview

void onProgressChange64(in nsIWebProgress aWebProgress, in nsIRequest aRequest, in long long aCurSelfProgress, in long long aMaxSelfProgress, in long long aCurTotalProgress, in long long aMaxTotalProgress);
boolean onRefreshAttempted(in nsIWebProgress aWebProgress, in nsIURI aRefreshURI, in long aMillis, in boolean aSameURI);

Methods

onProgressChange64()

Notification that the progress has changed for one of the requests associated with aWebProgress. Progress totals are reset to zero when all requests in aWebProgress complete (corresponding to onStateChange being called with aStateFlags including the STATE_STOP and STATE_IS_WINDOW flags).

This function is identical to nsIWebProgressListener.onProgressChange(), except that this function supports 64-bit values.

Note: If any progress value is unknown, then its value is replaced with -1.

  in nsIWebProgress aWebProgress,
  in nsIRequest aRequest,
  in long long aCurSelfProgress,
  in long long aMaxSelfProgress,
  in long long aCurTotalProgress,
  in long long aMaxTotalProgress
);
Parameters
aWebProgress
