 Hello
 I am sorry, I missed to add the relevant ROOT macro.

 Assuming you have the standard ROOT installation with Qt  (for example at CERN)

1. setup ROOT and QT environment. For example, at CERN "lxplus" you can execute the script http://root.bnl.gov/QtRoot/expert/26.03.2006/setup_root_cern_5.10.b.csh
2. Make a local copy ."rootrc" file to turn on the Qt-layer http://root.bnl.gov/QtRoot/expert/26.03.2006/.rootrc
3. Copy the C++ ROOT macro http://root.bnl.gov/QtRoot/expert/26.03.2006/FileDialog.C

ifndef __CINT__
# include <qfiledialog.h>
# include <qstringlist.h>
# include <qstring.h>

#endif
void FileDialog() {

// gSystem->AddIncludePath("-I$QTDIR/include"); // See: http://doc.trolltech.com/3.3/qfiledialog.html#getOpenFileNames   QStringList files = QFileDialog::getOpenFileNames ();   

  QStringList::Iterator it = files.begin();   while ( it != files.end() ) {

      printf ("Next file selected: %s\n", (const char *)(*it));
      ++it;

  }
}

4. Start ROOT session and execute 2 ROOT command     

root [0] gSystem->AddIncludePath("-I$QTDIR/include"); root [1] .x FileDialog.C++
5. You should get the Qt widget

   http://root.bnl.gov/QtRoot/expert/26.03.2006/FileDialog.png 6. You should see the the of the selected file names

     http://root.bnl.gov/QtRoot/expert/26.03.2006/FileDialogLxplus.log.png If you don't this maynave ment there is some bug to be fixed. Please file the ROOT bug report. Either way your kind feedback would be appreciated a lot.  Thank you, Hope this helps

My I remind people that there is the back door called Qt-layer

If you need "multiple selections" now you can use Qt class http://doc.trolltech.com/3.3/qfiledialog.html (you should turn on the Qt layer using ".rootrc". resource file see ftp://root.cern.ch/root/doc/chapter26.pdf page 393) As soon as ROOT TG provides the function you are seeking you may have replaced it back with the "TG" counterpart.

Hope this helps Valeri

Hi Kerry,  

This feature is not available yet in TGFileConaines but will come soon because of internal needs to have it. We will keep you informed.  

Cheers, Ilka

Dear Rooters,

How do I allow for multiple selections via a mouse click within a TGFileContainer?

Thanks
