Detailed Description

template<typename Slot>
class Dali::SlotDelegate< Slot >

SlotDelegates can be used to connect member functions to signals, without inheriting from SlotDelegateInterface.

Note that the object providing the member function is expected to own the SlotDelegate; therefore when the object is destroyed, the SlotDelegate destructor will automatically disconnect.

 class Example // This does not inherit from SlotDelegateInterface!
 {
 public:

   Example()
   : mSlotDelegate( this )
   {
   }

   ~Example()
   {
     // mSlotDelegate disconnects automatically here
   }

   void Animate()
   {
     Animation animation = Animation::New( 1.0f );
     animation.FinishedSignal().Connect( mSlotDelegate, &Example::OnAnimationFinished );
     animation.Play(); // fire & forget
   }

   void OnAnimationFinished( Animation& animation )
   {
     std::cout << "Animation Finished!" << std::endl;
   }

 private:

  SlotDelegate<Example> mSlotDelegate;
