About stylesheet, inherintance and stop

[tonnot]

I have a simple stylesheet applied to a Qframe which are going to content some custom widgets.
If I have
Qframe {} syntax every frame of every widget contained on tha main Frame inheritates the stylesheet
.Qframe {} means that only the current frame uses the style.

But if I want to use QFrame to have every frame with this style and write this code at my custom widget constructor :

this->setStyleSheet("");
this->setStyleSheet(styleSheet());

this->setStyleSheet("");
this->setStyleSheet(styleSheet());

To copy to clipboard, switch view to plain text mode 

it results that it does not stop the inheritance.
Any idea ?
Thanks
