QLineEdit padding problem with QTreeWidget

[Alundra]

Hi,
I have this stylesheet part loaded using "App.setStyleSheet( StyleSheet );" :

QLineEdit
{
  background-color: #201F1F;
  border: 1px solid #3A3939;
  border-radius: 2px;
  color: silver;
  padding: 2px;
}

QLineEdit
{
  background-color: #201F1F;
  border: 1px solid #3A3939;
  border-radius: 2px;
  color: silver;
  padding: 2px;
}

To copy to clipboard, switch view to plain text mode 

All works good everywhere but not with all tree widget because of "padding: 2px;".

Thanks for the help
