[Interest] QGaphicsItem deletion

[Igor Mironchik]

Hi folks,

Let's say I have QGraphicsItem, let it be Line. This Line has move 
handles - another QGraphicsItems, rectangles. Parent of the handles is 
the same as Line's. But Line own objects of handles with QScopedPointer.

When Line creates in c_tor() it creates handles, so handles adds to the 
scene after Line. When I delete Line from the scene by hand everything 
is fine: Line deletes and QScopedPointers free handles.

But if I close application and scene destroys with d_tor() in which it 
deletes all child items. So my question is it possible that handle will 
be deleted before Line, so QScopedPointer will try to free already 
deleted pointer?

Thank you.
