Detailed Description

A delegate for QLineEdit which initializes with model data.

Default implementation provided by Qt in QItemDelegate is not convenient for the user: the data provided by model is not displayed in QLineEdit. This delegate fix this issue. All delegates based on QLineEdit can potentially inherit this class.
