it's so nice that mediabar
Btw, thx MohammadAG for the compiling tip
now I got it.


I have changed the buttons to "flat". now only the icons are visible.
Upnext Im going to add a nice "bar-ish" background.
As I'm a total dev noob, I would put a label behind the buttons in the .ui and add a pixmap to it.
now add ressource file...

Would this be the right approach ?
