For a software I am developing I'd like to try to use a QColumnView widget.<br>All my gui is designed using the Designer and when I compile the .ui file which had the widget I get this error:<br><br>"Unknown Qt widget: QColumnView"
<br><br>both under Windows and under Linux.<br><br>I am working with Qt 4.3 and PyQt 4.3.<br><br>Any ideas ?<br><br>Thanks<br>Gianluca<br><br><br>
