Here is what i am doing :

Qt Code: 
  1. TalkWindow::saveConf();
  2.  
  3.     list<MotionStyle*>::iterator            mScenesIt;
  4.     list<Source*>::iterator                 mSourcesIt;
  5.     list<Font*>::iterator                   mFontsIt;
  6.  
  7.     //map<std::string, QTimer*>::iterator       mTimersIt;
  8.  
  9.     /*if (mDisplayStyle->isStarted())
  10.         mDisplayStyle->stop();*/
  11.     TalkWindow::on_stopButton_clicked();
  12.  
  13.     delete mDisplayStyle;
  14.  
  15.     for (mSourcesIt = mSources.begin(); mSourcesIt != mSources.end(); mSourcesIt++)
  16.     {
  17.         delete *mSourcesIt;
  18.         mSourcesIt = mSources.erase(mSourcesIt);
  19.     }
  20.  
  21.     for (mScenesIt = mScenes.begin(); mScenesIt != mScenes.end(); mScenesIt++)
  22.     {
  23.         delete *mScenesIt;
  24.         mScenesIt = mScenes.erase(mScenesIt);
  25.     }
  26.  
  27.     /*for (mTimersIt = mTimers.begin(); mTimersIt != mTimers.end(); mTimersIt++)
