ButtonExpandable
 Usage
• ButtonExpandable is an option for ButtonBox which specifies whether the button should expand to fill any GridBox position in which it appears.
Notes
• The default setting is ButtonExpandable->True. • This setting is usually used for all buttons that appear in palettes. • With ButtonExpandable->False the size of a button is determined purely by its contents, independent of its environment. • With ButtonExpandable->False, gutters will often be left between buttons in a GridBox. • New in Version 3.
