// connected to the update slots are not sufficent because unfortunatly,
// TQt does not provide a signal for changed item positions, e.g. during
// deleting or adding items. The problem with this is that this function does
// not catch updates which are off-screen, which means under some circumstances
// checkboxes have invalid positions. This should not happen anymore, but was
// the cause of bug 113458. Therefore, both the signals connected in the
// constructor and this function are necessary to keep the checkboxes'
// positions in sync, and hopefully is enough.
