void QGraphicsScene::changed(const QList<QRectF> &region) region list is empty



  • void QGraphicsScene::changed(const QList<QRectF> &region)
    This signal is getting emitted and sometimes the list of the region is empty
    what has been changed when the region is empty, do I need to consider this?

    Hi,

    That's surprising indeed. What are you doing in your scene ?
    Is there some pattern as to when you get an empty list ?

    What are you doing in the slot connected to that signal ?
