Hello Christophe,
Very likely you need to add -DR__QT cpp flag.
Anyway the patch you applied doesn't contain the last changes I made.
Tomorrow (I hope:-) I'll provide a patch for 3.05.04 with
the last corrections.
Mean time, can you try to get the last source from the CVS repository
(see : http://root.bnl.gov/QtRoot/QtRoot.html#source )
There one can find a script "root/root.diff/qtUtil/rootqtdiff"
Feel free to send me any question / problem you might have met.
The help text this script provides describes how any ROOT version can be
adjusted to use Qt-layer.
This last CVS repository contains and advanced example of the pure
Qt-based RootShower application (Windows user will get it automatically
just the upgrade there ROOT Qt-based installation from
http://root.bnl.gov
(see: ScreenShot http://root.bnl.gov/QtRoot/RootShower.png )
The example provides the way to create Qt-based user ROOT application
that will work both on Windows and UNIX platforms.
I would advice you try sticking with the approach that is present below
to build your own application.
The directory "root/test/qtRootShower" contains Qt-based edition of the
original RootShower code written by Bertrand Bellenot
( Bertrand.Bellenot@alcan.com). The orginal Non-Qt code it is available
from:
ftp://root.cern.ch/root/RootShower.tar.gz
So you can compare two different approaches to judge which one you would
like to follow.
The goal of this example is to show how Qt-based ROOT can be used to
build
the complex GUI.
I tried to preserve the original design and code replacing the ROOT gui
classes
with some from Qt GUI equivalents if possible.
To run this example one needs to install the ROOT Qt-based version from
http://root.bnl.gov and invoke the example as follows:
root RootShower.CC
The source code of the Qt-based version is available from the
CVS repository (see: http://root.bnl.gov/QtRoot/QtRoot.html#source )
To retrieve the source code of the example alone do:
cvs -d :pserver:cvs@usatlas.org:/rootbnl/cvs co root/test/qtRootShower
To re-compile (One is required to install Qt package first) the example
from the scratch:
1. Make RootCint dictionary:
Windows:
nmake -f Makefile.dict
Unix:
make -f Makefile.gmake.dict
2. Build the main Makefile with "qmake" utility
qmake RootShower.pro
3. Compile and build the share (DLL) library:
[n]make
4. run the example:
root RootShower.CC
5. Enjoy.
