Problems when reading file in QT

ROOT
1

Hello all,

I am using QT and want to read root file in my program. When I read .root file in my main() function, it works well, but when I read the file in my own class, it gives these warnings and fails to read the file,

Warning in TClass::TClass: no dictionary for class TTree is available
Warning in TClass::TClass: no dictionary for class TBranch is available
Warning in TClass::TClass: no dictionary for class TLeafI is available
Warning in TClass::TClass: no dictionary for class TLeaf is available
Warning in TClass::TClass: no dictionary for class TLeafF is available
Warning in TClass::TClass: no dictionary for class TBranchRef is available
Warning in TClass::TClass: no dictionary for class TBranchElement is available
Warning in TClass::TClass: no dictionary for class TLeafElement is available

I have already add these lines in my .pro file,

INCLUDEPATH += $(ROOTSYS)/include
include("$(ROOTSYS)/include/rootcint.pri")

It seem that I should do some other configuration? Thanks a lot.

I solved the problem. I forgot
gSystem->Load("libTree.so");
in my code.
