    [quote author="raven-worx" date="1375899990"]this->view() returns an QAbstractItemView which is derived from QWidget. QWidget has a method named setMinimumWidth() ....
    what Qt version do you use?![/quote]

    Sure, QWidget has a member function setMinimumWidth(),

    my problem is inside setMinimumWidth(),

    this->view()->sizeHintForColumn(0) ( QWidget hasn't a methode sizeHintForColumn(0)

      no...but QAbstractItemView does!
      Since you implicitly cast the view instance to a QWidget it's clear that the compiler complains about it!

          @
          QWidget *view = this->view() ;
          @
          to
          @
          QAbstractItemView *view = this->view() ;
          @

                        This works perfect, Thank you very much.

                        [quote author="raven-worx" date="1375879559"]you can subclass QComboBox and reimplement showPopup() method if you need the size content dependent. Something like this:
                        @
                        void MyComboBox::showPopup()
                        {
                        this->view()->setMinimumWidth(this->view()->sizeHintForColumn(0));
                        QComboBox::showPopup();
                        }
                        @[/quote]
