QWebView problem with flash

[TuBylem]

Hi guys,
I had written a music player application in C# and I have decided to rewrite it in QT, but I have a huge problem with QWebView (which is similar to WebBrowser in C#). My application uses a flash player from the website. WebBrowser's (C#) WebBrowserProgressChangedEvent sends to me the signal (-1), when the flash player has just finished his job, but QWebView doesn't. In this application I have to know when a current track is finished, to start the next one, so please help me. How can I solve this problem?

I have attached console diagrams from both applications (they say how WebBrowserProgressChangedEvent (C#) and loadProgress(int) (QT) signals are changing) and QT source code
