I am creating a phonon video player. In my project , i have to navigate to and from the video player page.
videoplayer is quit working 3 or more times when navigated. But after that, only audio is heared, the video is not displayed...

my doubts,

* How to kill instances of videoplayer when naviagted.(on button click)

i used videoplayer->deletelater(); and videoplayer->~videoplayer(); But the error visual studio just in time debugger displays "new instance is created ".

* how to use inheritance in qt so that i can control videoplayer in all my subclasses
