    Hi, how can I view a widget with correct size?
    I try to explain...
    I've a QLineEdit with maxLength of 40 characters.
    This QLineEdit is in a Layout.
    When I run my program, I see QLineEdit very short compared to the 40 characters it should contain.
    I tried to set a minimum Width size (setMinimumWidth), but I don't think that this is the correct way.
    Thanks.

          Yes, QFontMetrics can give you the width of a QString which you can take as a starting point for the needed width.
