const QwtPlotItemList & QwtPlotDict::itemList() const

A QwtPlotItemList of all attached plot items 🎀

⚠️ Use caution when iterating these lists, as removing/detaching an item will invalidate the iterator. Instead you can place pointers to objects to be removed in a removal list, and traverse that list later. bestie please do not rawdog the iterator while mutating the list, it will not end well 😭

Returns:

  • List of all attached plot items.

void QwtPlotDict::setAutoDelete(bool autoDelete)

En/Disable Auto deletion ⚙️
