Indicates whether a timeout event has triggered and that a refresh of the connection needs to occur.
public bool RefreshNeeded { get; set; }
Default value is false
Changes to true if a timeout event has triggered.
If a timeout has been returned and the RefreshNeeded property is false, a timeout event has truly happened. If RefreshNeeded property is true, just the window hosting the MedicalWebViewer (such as a BrowserForm) needs to be restarted due to the MedicalWebViewer refreshing itself.
This property allows the user to catch timeout events and react to them as they see fit. If a request is returned with a failure message, such as GetImage (string sopInstanceUID) returning an empty string, the RefreshNeeded property can be checked after to see if that failure was caused by the query returning no results or if that failure was caused due to a timeout.
This was added so that when the browser refreshes itself, like when the user changes some options in the MedicalWebViewer, the MedicalWebViewerExternalController object can indicate via the RefreshNeeded property whether a genuine timeout/failure occurred or if the window hosting the browser needs a refresh.
