 of an external application.

 Note that cancelling the load via the nsICancelable interface will release
 the reference to the launcher dialog.

Methods

 when the stand alone progress window actually closes, it calls this method
 so we can release any local state...
void closeProgressWindow() 
 Use aApplication to launch with this content.
 NOTE: This will release the reference to the nsIHelperAppLauncherDialog.
 @param aApplication nsIFile corresponding to the location of the application to use.
 @param aRememberThisPreference TRUE if we should remember this choice.
void launchWithApplication(in nsIFile aApplication, in boolean aRememberThisPreference) 
 Called when we want to just save the content to a particular file.
 NOTE: This will release the reference to the nsIHelperAppLauncherDialog.
 @param aNewFileLocation Location where the content should be saved
void saveToDisk(in nsIFile aNewFileLocation, in boolean aRememberThisPreference) 
 The following methods are used by the progress dialog to get or set
 information on the current helper app launcher download.
 This reference will be released when the download is finished (after the
 listener receives the STATE_STOP notification).
void setWebProgressListener(in nsIWebProgressListener2 aWebProgressListener)
