A Spacer object is invisible in the user interface and is only used when working in grid layout mode. It defines a space of fixed size that you can use to ensure that neighboring form objects have enough space to show their contents. Typically, you would use a spacer next to a table or graphics object to ensure that they are rendered properly. If the user resizes the window so that it becomes smaller than the size of the spacer, the effective size of the window is maintained by displaying scroll bars. The figure below shows the Settings window of a spacer object.
