Detailed Description

The DALi namespace.

The class should implement Dali::ConnectionTrackerInterface, or inherit from Dali::ConnectionTracker.

Since:

2.4, DALi version 1.0.0

This enforces automatic disconnection when an object is destroyed, so you don't have to manually disconnect from signals.

Alternatively, you can use a Dali::SlotDelegate if you don't want to inherit.

E.g:

 class MyClass : public ConnectionTracker
 {

   void Callback( Actor actor, const TouchEvent& event )
   {
     ...
   }

   void Init()
   {
     Actor actor = Actor::New();

     actor.TouchedSignal().Connect( this, &MyClass::Callback );
   }

   ~MyClass()
   {
     // ConnectionTracker base class automatically disconnects
   }
 }

Since:

2.4, DALi version 1.0.0
