[Qt-interest] Build Error with Q_PROPERTY() READ method ; How to invoke a Q_PROPERTY's READ only method

[Santhosh Y]

Hi,

Please see the following class, from which I am trying to define a 
Q_PROPERTY,  method which is a READ method.
///////////// Issue 1 ///////////////////
class NewGUICOMObj : public QObject
{
     Q_OBJECT

         Q_PROPERTY(bool RenewIACallBack  READ RenewIACallBack)

     public:
             ............................
}
*1>midl\oleaut32.dll : error MIDL2020 : error generating type library : 
SetFuncAndParamNames failed : RenewIACallBack (0x8002802C)*



/////////////The above issue will go,  If I do the following  
///////////////////

class NewGUICOMObj : public QObject
{
     Q_OBJECT

         Q_PROPERTY(bool renew  READ RenewIACallBack)

     public:
             ............................
}

But with this change I am not able to make use of this READ property, 
which I explained in the below Issue 2.

///////////// Issue 2 ///////////////////
This code, is to invoke COM object and call an interface which is 
defined using Q_PROPERTY.

    HRESULT hres = 
CoCreateInstance(QUuid("{084EF014-6C9B-4d50-8756-263CDAC6DE4B}"), // 
NewGUICOMObj Class ID ==>CLSID
                 0, CLSCTX_SERVER, IID_IUnknown, (LPVOID*)&ptr);

         if (hres == S_OK && ptr !=NULL ) { //success

              //Creating a QAxObject that wraps the COM object 
referenced by IUnknown.
             QAxObject* comObj= new QAxObject (ptr);

*            comObj->property("RenewIACallBack");* //Why would this 
fail?, Is it not the correct way of invoking READ only type Q_PROPERTY 
on QObject.
     } else { //failure
     }


Thanks in advance, if some body helps in this regard.
I am struck and dont know how to solve this!
