QStyle functionality to retrieve text paint area for a line edit

When calling SE_lineEditContents to get the rectangle that comprises the rectangle inside the line edit, the code takes the rectangle, and puts a hard coded 2/1 pixel margin for the vertical and horizontal margins. It would be nice if there were a call from QStyle or similar (e.g. SE_lineEditTextRect) that would take this into account - i.e some type of style call to get this margin or the entire rect.
