Plugin Loading and Signal Handling in Qt4

[liquid]

Thanks.
Can you post a simple example code, which describe how to make a plugin interface, which return an object that provides signals and slots.

class PluginInterface
{
 public:
     virtual ~PluginInterface() {}
     virtual QObject* someObjectWithSignalsAndSlots() const = 0; // <--
     ...
};
 
Q_DECLARE_INTERFACE(...)

class PluginInterface
{
 public:
     virtual ~PluginInterface() {}
     virtual QObject* someObjectWithSignalsAndSlots() const = 0; // <--
     ...
};

Q_DECLARE_INTERFACE(...)
