An object class that has abnormally shaped Settings pages (for example, the pages may be very wide) can use this method to ensure that, when a Settings notebook is initially displayed for an instance of the object class, that Settings notebook will be of a suitable size to view the whole Settings page without clipping it. The size specified by this method is used only the very first time that a Settings notebook is displayed; thereafter, the Settings notebook size and position will be saved by the system on a per-object basis.
