Have you checked the QGraphicsLayout example already?

@_ said in Does QLayoutItem delete its managed item in its destructor?:

@Pl45m4 said

QLayoutItem does not delete anything, same as all QLayouts.

QLayoutItem is not a layout, rather, it is a layout item, so I don't understand your comment.
On the contrary, layouts are also layout items (it is so in order to allow sublayouts).

It means what it says.

@_ said in Does QLayoutItem delete its managed item in its destructor?:

If i understand that correctly, layouts delete their child layouts in their destructor.
Is it done through the layout item destructor?

Check it yourself.

QLayoutItem destructor does basically nothing, except destroying the QLayoutItem itself

https://code.woboq.org/qt5/qtbase/src/widgets/kernel/qlayoutitem.cpp.html#_ZN11QLayoutItemD1Ev

whereas, if you delete a QLayout, it will delete all of its child-layouts, but not their widgets

https://code.woboq.org/qt5/qtbase/src/widgets/kernel/qlayout.cpp.html#_ZN7QLayoutD1Ev

No, it doesn't. The QLayoutItem is not the parent of the widget, it is not a QObject. That's not its job.

@onek24 You're absolutely right. I didn't yet grasp that the QLayoutItem in fact behaves as a kind of proxy for the actual widget (or child-layout). Thanks for the clarification.

Yay, that's what I was looking for. Thanks!
