Hi all,

With CGAL 3.8 and QT 4.7.3 on Visual Studio 2008, I tested this minimal code:

#include <CGAL/IO/Qt_widget_Nef_3.h>

int main(int argc, char* argv[])
{
    return 0;
}

which is basically a stripped off version of the last code in

http://www.cgal.org/Manual/latest/doc_html/cgal_manual/Nef_3/Chapter_main.html

and this is the output:

Indeed, there was no qpopupmenu.h in Qt directory. I searched on
Qt-related forums, and found here

http://doc.trolltech.com/4.7/porting4.html#qpopupmenu

that "For most purposes, QPopupMenu has been replaced by QMenu in Qt
4. For compatibility with older applications, Q3PopupMenu provides the
old API and features that are specific to pop-up menus. Note that,
when using Q3PopupMenu, the menu's actions must be Q3Actions."

So:

1) I am wondering whether this is obsolete and will be replaced in the
next release? Or is it simply my mistake?

2) I suppose to correct this I have to edit Qt_widget_OpenGL.h and
rebuild the whole CGAL again. Is there a simple workaround for this
problem without doing this?

Thank you.

Best regards,
Nicholas
