QColorDialog style sheet modification

Hello everybody !
I've just create a simple application which a very simple style sheet that change the background color of widgets and make some other little changes.

In this application I use a QColorDialog that appears correctly with the exception of the slider which have the default background color instead of the modified one:

Currently I only define this line in order to change the background color:

Code:

---

QDialog
{
	background: rgb(180,180,180);
}

---

Any suggestions ?

Thanks,

Angelo
