Set a StyleSheet for a whole widget in Qt

Question

I have a custom widget which inherits from QWidget and contains some labels in its layout. I would like to change the background color of the widget and the labels in the widget (this is, everything!) every time I put the mouse over it.

When using *:hover { background: red; } in my custom widget, I only get the contents red when moving the mouse over the labels, but not outside them, between labels, etc. I don't understand this behavior taking into account that I put the StyleSheet in the parent widget.

Any ideas? Many thanks,

Finally I solved the problem creating a QFrame inside the main QWidget and setting the StyleSheet of that QFrame.
