[Qt-interest] Few queries on Q_PROPERTY() macro

[Santhosh Y]

Hi ,

Please see the following class, from which I would like to expose few 
more interfaces as part of COM object
======================================================================================
// NewGUICOMObj - COM object ;     It is derived from QObject, for 
adding Q_PROPERTY
class NewGUICOMObj : public QObject
{
         Q_OBJECT
         Q_PROPERTY(bool visible READ isVisible WRITE setVisible) //This 
is I am able to write correctly; And also I am able to use from tester 
side  using this com object
*         //Q1:  What is wrong with the following Q_PROPERTY declaration*
         //Q_PROPERTY(char *path  READ readPath WRITE setPath)
    public:
         // constructor
         NewGUICOMObj (char* p, QObject * parent = 0) : ptr_(p), 
QObject(parent)
         {
         }
*         //Q2: Following Method I would like to expose on COM object*. 
*Please tell me how to write using Q_PROPERTY*
          void RenewCallback(eOwner owner)   {...........}

*         // Q3: Following Method also I would like to expose on COM 
object*. *Please tell me how to write using Q_PROPERTY*
         int createInstance ()
         {
             int value;
             ................................ // creation goes here
             return value;
         }

         bool isVisible () const {return true;  /*TODO*/}

         void setVisible(bool on)
         {
             this->visible = on;
             createInstance();
         }

         void setPath (char* path) {this->ptr_ = path;}
         char* readPath ()const  {return ptr_;}
     private:

         bool  visible;
         char* ptr_;
         AeraLauncherNS::AeraController* controller;
};
======================================================================================
In the above class, please answer my 3-questions.

Regards,
Santhosh
