Compile Combination of qtwinmigrate + qtpropertybrowser Under VC++ 2008

I need to display a property browser under a MFC app.

I try to combine and compile the solution for the two

http://qt.nokia.com/products/appdev/add-on-products/catalog/4/Windows/qtwinmigrate/
http://qt.nokia.com/products/appdev/...opertybrowser/

I am using VC2009, QT 2009.04 with Visual Studio Add-On 1.1.1

Take note, under my machine, there are no problem for me to compile them successfully separately.

I copy, and add all exsiting CPP and HEADER files found in
Code:

qtpropertybrowser-2.5-opensource\src
into
Code:

qtwinmigrate-2.8-opensource\examples\qtdll
Here is how my new project looks like in the screen shoot (qtwinmigrate - windows at right most)

The qtpropertybrowser, is the project which I am able to compile with no problem :
Code:

1>------ Rebuild All started: Project: simple, Configuration: Release Win32 ------ 1>Deleting intermediate and output files for project 'simple', configuration 'Release|Win32' 1>Moc'ing qtpropertybrowserutils_p.h... 1>RCC ..\..\src\qtpropertybrowser.qrc 1>MOC ..\..\src\qtvariantproperty.h 1>MOC ..\..\src\qttreepropertybrowser.h 1>MOC ..\..\src\qtpropertymanager.h 1>MOC ..\..\src\qtpropertybrowser.h 1>MOC ..\..\src\qtgroupboxpropertybrowser.h 1>MOC ..\..\src\qteditorfactory.h 1>MOC ..\..\src\qtbuttonpropertybrowser.h 1>Compiling... . . . 1>Compiling... 1>moc_qtpropertybrowserutils_p.cpp 1>Linking... 1>Embedding manifest...
However, when come to build modified version of qtwinmigrate (original version of qtwinmigrate was able to compiled with no problem)
Code:

1>------ Rebuild All started: Project: qtdialog, Configuration: Release Win32 ------ 1>Deleting intermediate and output files for project 'qtdialog', configuration 'Release|Win32' 1>Moc'ing qtpropertybrowserutils_p.h... 1>Moc'ing qteditorfactory.h... 1>Moc'ing qtvariantproperty.h... 1>Moc'ing qttreepropertybrowser.h... 1>Moc'ing qtpropertymanager.h... 1>Moc'ing qtpropertybrowser.h... 1>Moc'ing qtgroupboxpropertybrowser.h... 1>Moc'ing qtbuttonpropertybrowser.h... 1>Moc'ing qwinwidget.h... 1>Moc'ing qwinhost.h... 1>Compiling... . . . 1>Compiling... 1>moc_qtpropertybrowserutils_p.cpp 1>moc_qteditorfactory.cpp 1>.\Release\moc_qteditorfactory.cpp(74) : error C2027: use of undefined type 'QtSpinBoxFactoryPrivate' 1> c:\documents and settings\yan-cheng.cheok\my documents\downloads\qtwinmigrate-2.8-opensource\qtwinmigrate-2.8-opensource\examples\qtdll\release\../../../lib/qtpropertybrowser-2.5-opensource/src/qteditorfactory.h(97) : see declaration of 'QtSpinBoxFactoryPrivate' 1>.\Release\moc_qteditorfactory.cpp(74) : error C2227: left of '->slotPropertyChanged' must point to class/struct/union/generic type
My questions is

1. Why qtpropertybrowser just perform "Moc'ing" in 1 file, but qtwinmigrate perform "Moc'ing" in so many files?
2. Why qtpropertybrowser just compile "moc_qtpropertybrowserutils_p.cpp", but qtwinmigrate try to compile so many "moc_....cpp"?
