Hi there.
I'm new in Qt (I have the 5.4 version). I have been watching the default examples projects and I found a "Quick Player" project. It has a transparent background and it looks very nice. Because I am new, I can not understand all the code and the lot of funtions. So I need help.

How can I have a transparent backgroud (like the example) in my own project? I have been trying without success. I found examples, but they don't look like the Quick Player.


I'll appreciate if some one can help me to make my own window looks like this.
