/*!
 @brief    Notification which is posted whenever a checkbox is going to be
 removed from the superview and deallocced
 
 @details  Because of the way NSPredicateEditor constructs rows from templates,
 rows are quite "disposable" and this removal and dealloc may happen when,
 for example, the attribute type (left popup) of a row is changed.  If the
 checkbox is in the active "Replace" row, that is, if its state is ON, a
 someone will need this notification to hide or disable the "Replace" controls.
 
 Use of this notification is a kludge.  A better way would be to make the
 related NSPredicateEditor observe the 'superview' property of the checkbox.
 However, when I simply implemented -observeValueForKeyPath:::: in
 MyPredicateEditor, with an empty implementation, when the view loaded, in
 -[MyPredicateEditor viewDidMoveToWindow], the line of code where it
 adds a row using the IBAction method, [self addRow:self], would raise
 an exception saying that it was trying to add a row at index 1 which was
 out of bounds since the number of rows is currently 0.  I think maybe this is
 a weird bug in NSPredicateEditor.  I started to try and reproduce it in a
 demo project but it was taking too long to get the stupid predicate editor
 to display anything at all. */
