Control the position of the icon in a QLineEdit

Hi everyone.

I've subclassed QStyle to control the aspect of my app. After customizing the aspect of the QLineEdits, I need to add an icon inside the QLineEdit and it has to be clickable by the user. I've seen that I can use the QLineEdit::addAction-1 to add and action and an icon in the QLineEdit. The problem arises with the position in which it draws the icon because as I have the customized QLineEdit, the icon draws too near the edge of QLineEdit. I need to separate more icon QLineEdit edge. Does anyone know how to control the position of the icon in the QLineEdit?

Thanks.
