FWEventItemsManager has ownership of the items it contains.

Note that because of the way we keep track of removed items, m_items[i] could actually be 0 for indices corresponding to removed items.

void FWEventItemsManager::removeItem ( const FWEventItem *  iItem )

private

Remove one item.

Notice that rather than erasing the item from the list, it is preferred to set it to zero, I guess to catch accesses to remove items and to avoid having to recalculate the current selection.

GE: I think this is a broken way of handling removal of objects. The object should be properly deleted and the current selection should be updated accordingly.
