Equality checking of ob is based on Equals, and conventionally this does not identify TBarButtons with equivalent keys. If an application holds what may be a cloned reference to a button present in this group, then developers are advised to use the FromKeyButton method to locate the button within this collection and then call this method on that button object.
If an application needs to know whether ob was successfully removed, it should compare the pre-removal Count to the post-removal Count. On a successful removal, these two values are different.
