QObject subclass in a QList

[plan_rich]

Thx for you fast replay.

And what about memory of the QList<*> ?
Do i have to manage memory of the QList's data?

Can someone give me a guide about memory management of Qt? So do i have to delete pointers of QObjects or not?

You have to delete everything yourself, except that QObject deletes all its children itself.

So for example when you add a widget to a layout, the layout becomes parent of that widget and deletes the widget when it is destroyed.

But you need to delete your custom objects yourself.

Your list will probably be a member variable of some object. in its destructor you call:

// iterates through all items of the list and calls delete on them, but does not remove the entry from the list!
qDeleteAll(list);
// removes all entries from the list.
list.clear();

// iterates through all items of the list and calls delete on them, but does not remove the entry from the list!
qDeleteAll(list);
// removes all entries from the list.
list.clear();
