Is it safe to overwritten a widget value right after calling deleteLater?

[Roberrt]

When i call shadow_map[widget].eff->deleteLater(); and in the next line overwrite the value
of the eff into the shadow_map, does it still will get deleted as its value got overwritten?

    struct Shadow
    {
		GraphicsEffect* eff = nullptr;
      //...
    };


	QMap<QWidget*, Shadow> shadow_map;

	void setShadow(Shadow& shadow, QWidget* widget = nullptr)
	{
		if (widget)
			shadow.widget = widget;
		else
			widget = shadow.widget;

		GraphicsEffect* eff = new GraphicsEffect(...);

		shadow.eff = eff;

		if (shadow_map.contains(widget))
		{
			shadow_map[widget].eff->deleteLater();
			shadow_map[widget] = shadow;
		}
   }

You don't override the value, just a pointer so you don't modify the object deleteLater() was called upon.
