Hello,
I have a QGraphicsItem derived class called wire, and it has children that are verticies. The verticies are selectable so that they can be manipulated.
The question is, is there a good way to detect if something is trying to delete this object, and prevent it or possible tell another object to be deleted?
My wire gets messed up when a vertex is unexpectedly removed. I'd like to make it notify the wire that a particular vertex is being deleted... and also a way to prevent some items from being delted at all.
