D28074: [kstyle] Avoid invalid iterators in qDeleteAll

[Vlad Zahorodnii]

zzag added a comment.


  Another way around is not to use `qDeleteAll`, e.g.
  
    for( QWidget* widget : _widgets )
    { unregisterWidget( widget ); } // or uninstallShadows()
  
  Either way, I'm open to suggestions. :-)
