Hello there, could anyone help me with scrollbars at QWebView?

I've made 2 Scrollbars for it, here's code: http://rafb.net/p/v30uen34.html , and it's still not working please help me, tell me what i'm making wrong (compilator is happy, and it doesn't crash).

I'm making scrollbars because this built-in doesn't work for me :/ They are only on specified width & height, don't know why. I'm new to Qt & C++ then please, don't be mad on me.

Thanks, Lashus
