Re: C++ question

Hi Hans,

Indeed, that's one of the missing features of the C++ API...
You will have to use the CComAPIHandler to get the Member property.
Here is some code that should help you if it's the first time you're using it.
The tricky part is that the SceneItemCollection COM object is not
translated in a CRefArray by the GetProperty, so you have to use the
CComAPIHandler all the way long...

    CComAPIHandler oGroup( oGroupRef );
    CValue oGroupMembers( oGroup.GetProperty( L"Members") );
    CComAPIHandler oGroupSceneItems( oGroupMembers );
    long nbMembers = oGroupSceneItems.GetProperty(L"Count");
    Application().LogMessage(L"NB Members: " + CValue(nbMembers).GetAsText());
    for (long i=0; i<nbMembers; i++)
    {
        CValue oRef;
        CValueArray oArgs(1);
        oArgs[0] = CValue(i);
        oGroupSceneItems.Invoke(L"Item", oGroupSceneItems.PropertyGet , oRef, oArgs);
        X3DObject oObj(oRef);
        Application().LogMessage(L"Member : " + oObj.GetFullName());
    }

Hope this helps!

Hi All,

 

How do one access the members in a group through the c++ interface?

 

The XSI::Group class doesn't seem to  have a GetMembers function...

 

Hans.
