[Qt-interest] How to instantiate factory instance from a tester application

[Santhosh Y]

Hi,

I am trying to support my existing Qt application as an activeX server.  
I started with a simple example here.
I have 2- QWidgets[parent widget holds child widget] . On top of 
QAxFactory I have added my factory class,
which overwrites / implements base class virtual / pure virtual methods 
and can be used from outside to access QWidget (parent)

I built these in to an "template lib". (Please see my .pro file)

I have written a tester application(stand alone), which will invoke 
factory object and hence the objects inside it.

*Q1: The problem I am facing is how to instantiate QAxFactory object and 
subsequently creating objects...*

Please find the following attached zip files with this e-mail:

   1. ComApp.zip
          * This folder contains  following files
               1. objects.h         // Declaration of Elements in side
                  factory   (2 - QWidgets;  One inside other)
               2. objects.cpp     // Definition of Elements in side factory
               3. factory.h          // factory declaration &
                  defintion   (Qaxfactory subclass)
               4. hierarchy.pro   // project file
               5. qaxserver.rc    // resource file
               6. main.cpp         // factory macro declaration
               7. qaxserver.def  // modular defintion file
               8. hierarchy.inf
               9. qaxserver.ico
   2. TesterFile.zip
          * It has test.cpp
               1. This file #import (.tlb) of the above application
               2. Here I am trying to invoke factory and create object
                  inside it, and launch the QApplication (event loop)

Please give me inputs by going through the test.cpp file for how to 
initialize factory and hence the objects inside it. I have written few 
comments in side test.cpp file where I had some confusion.
Please suggest me how to do. You are most welcome if there any better 
ways of doing it.

*Q2: When I change to  "CONFIG += activeqt   dll"    from    " CONFIG += 
qaxserver dll"  in project file, it is giving following error.*

         link /LIBPATH:"c:\Qt\4.5.2\lib" /NOLOGO /DEBUG /DLL /MANIFEST 
/MANIFESTFILE:"debug\hierarchyax.intermediate.manifest" 
/DEF:qaxserver.def /OUT:debug\hierarchyax.dll
@C:\DOCUME~1\SANTHO~1.SOF\LOCALS~1\Temp\nm499.tmp
qaxserver.def : error LNK2001: unresolved external symbol DllCanUnloadNow
qaxserver.def : error LNK2001: unresolved external symbol DllGetClassObject
qaxserver.def : error LNK2001: unresolved external symbol DllRegisterServer
qaxserver.def : error LNK2001: unresolved external symbol 
DllUnregisterServer
qaxserver.def : error LNK2001: unresolved external symbol DumpIDL
debug\hierarchyax.lib : fatal error LNK1120: 5 unresolved externals

All those APIs are exported in .def file. Where to define and declare these?

I think for exposing Interfaces from my COM objects , I should be 
including  "CONFIG += activeqt   dll" instead "CONFIG +=qaxserver".
Please comment on this.

Regards
