Hi,

I want to configure objects that are encapsulated in other objects using a configuration file and a plugin architecture, so I do not know in advance which objects are contained within the object. Is it possible to do this using the QObject:roperty() function?

Example:
Qt Code: 
  1. class BInterface {
  2.         public:
  3.                virtual ~BInterface() {}
  4.                virtual int foo() = 0;
  5. };
  6.  
  7. class B : public QObject, public BInterface
  8. {
  9.        Q_OBJECT
  10.        Q_PROPERTY(int b READ b WRITE setB );
  11.        public:
  12.                virtual ~B() {}
  13.                virtual int foo() { return mv_b; }
  14.                const int b() const { return mv_b; }
  15.                void setB( const int b ) { mv_b = b; }
  16.       private:
  17.               int mv_b;
  18. };
  19.  
  20. class A : public QObject{
  21.    Q_OBJECT
  22.    Q_PROPERTY(BInterface* B READ B WRITE setB);
  23.    public:
  24.          A() { mv_B = NULL; }
  25.          virtual ~A() { if(mv_B) delete mv_B; }
  26.          const BInterface * B() { return mv_B; }
  27.          void setB( const BInterface * B ) { if (mv_B) delete mv_B; mv_B = B; }
  28.    private:
  29.          BInterface * mv_B;
  30. };
To copy to clipboard, switch view to plain text mode 

what I want to do is something like:
Qt Code: 
  1. QObject * objA = new A();
  2. BInterface* b = a.property("B");
  3. b.setProperty("b", someValue);
To copy to clipboard, switch view to plain text mode 
can this be done at all?
