How do UN-subscribe from an event?

How does one UN-subscribe from an event?

Code: Select all

   while ( mCur )
   {
      mNext = mCur->NextItem;
      if ( mCur->mDWSlotRow )
      {
         mCur->mSISlotBox->removeEvent( CEGUI::StaticImage::EventDragDropItemDropped );
         mCur->mSISlotBox->removeEvent( CEGUI::StaticImage::EventChildAdded );
         mCur->mSISlotBox->removeEvent( CEGUI::StaticImage::EventChildRemoved );

         if ( mCur->GUIInvItemEquip )
         {
            mCur->mSISlotBox->removeChildWindow( mCur->GUIInvItemEquip->getDragContainer() );
            delete mCur->GUIInvItemEquip;
         }

         mWinMgr->destroyWindow( mCur->mDWSlotRow );
      }

      delete mCur;
      mCur = mNext;
   }



Causes me all kinds of grief when mWinMgr->destroyWindow( mCur->mDWSlotRow ); gets called.

Hi,

When you subscribe to an event, you are returned an instance of Event::Connection, you can use this object to keep track of, and disconnect, from the event.

There is also an Event::ScopedConnection which will auto-disconnect from the event when the ScopedConnection object goes out of scope (is destroyed).
