how to set a child label transparent

[qt_user]

I ahve used the command:
this->setStyleSheet( "QFrame {border-image: url(:/images/background.png); }"); for displaying an image in the background.
Now when I create Labels(children) on the same widget(which is bordered), the labels also get bordered.........
I want to know How to set the Labels transparent without the use of the paintEvent function?

set a empty style sheet to the labels or use global QFrame > QLabel selector to set a null border.
