Hi Rene,

I am asking because it is not obvious to me how to insert a ROOT object that does not inherit from QWidget. I am not sure how to go about doing it so I have not tried.

I am using Qt because I needed the QFileDialog multiple selection functionality. In the mean time I've grown to like using the Qt designer, so in my eyes the ultimate use of designer would be to have access to all the ROOT widgets as well. In the end it would give me more tools to choose from in developing my application.

Thanks
Kerry

Kerry,

  -Are you asking the question because you tried and failed?
  -What you request should work
  -Could you explain why you use Qt and not directly the ROOT GUI.
  -Do you have sometyhing in your Qt-based GUI that you cannot do

   in a simpler way with the ROOT GUI?

I am interested in using some of ROOT's widgets (particularly TGDoubleScrollBar objects) within my Qt application. According to the 5.11.02 release notes in the GSI QtRoot section this is possible, but the only example given is the use of TQRootCanvas. Is it possible to do what I want?
