/** @brief A QWidget derived from QLineEdit, aiming to provide a simple-to-use wrapper around QLineEdit

    By default, a readonly CLineEdit looks like an ordinary label, whereas a non-readonly
    CLineEdit contains blue, underlined text. As soon as the non-readonly widget receives
    the focus, the color falls back to the palette, the underline disappears and the modifiable
    text is selected.
