 Replying to [comment:14 fine@…]:

 One should see the https://savannah.cern.ch/bugs/?94032 also

 QtRoot is a separate project to root ? Is QT support not baked into the
 root code itself ?

 > The QtRoot support is baked into the root code for the X11 platform
 only.

 > For the other platforms (Windows / Mac "native") one should use the
 http://root.bnl.gov/QtRoot/How2Install4Unix.html . The problem for the Mac
 is that I have no Mac machine myself. I can not respond quickly to the
 reports coming from Mac users . I have to forward it to some QtRoot Mac
 users and rely on their feedback and support.
 >
 > Another  thing to consider. Due lack of demand the scope of QtRoot
 project was limited by the ROOT-based Qt application. I.e. the
 applications creating the QApplication Qt instance rather TApplication
 instance of ROOT. The bunch of such applications are included into the
 QtRoot distribution and available from
 http://qtroot.svn.sourceforge.net/viewvc/qtroot/trunk/qtExamples/
 >
 > That means you can create the Qt application and populate your Qt GUI
 with ROOT TCanvas/TPad -like graphics and some other ROOT-aware GUI
 components  from QtRootGui package (that is not a part of the root
 distribution) .  This is what 100% of the QtRoot users want. The inverse
 approach is possible but it is not  tested thoroughly.  Roughly say, you
 may not add the Qt widget-based  object to your ROOT GUI-based (TG-ROOT
 classes  based ) application and I do not see  anybody who wants / needs
 it.
 >
 > In the other words it is not recommended to mix Qt and ROOT GUI within
 one application. The code may work bit it will be not "stable " for sure.
 TCanvas is not regarded as ROOT GUI. Speaking ROOT GUI one means the
 "usual" GUI components like slider, menu, button, combo boxes etc.
 >
 > From this stand point it useless to test QtRoot installation using
 root.exe application. One should use
 http://root.bnl.gov/QtRoot/How2Install4Unix.html#testqtroot instead.

 >  Hope it helps.
