Customizing the metamodel : Modifying the aesthetic look of dialogs
  
Modifying the aesthetic look of dialogs
A certain amount of control can be obtained over the display of controls and their labels within the dialogs. For example, labels can be displayed over the control, directly next to the control, or separated by an amount of space determined by the longest label within a group.
It is not necessary to figure out how many controls can fit on one dialog page. System Architect automatically computes the number of controls that fit on a dialog page based on the amount of space available for display, and breaks up a dialog into pages that you may flip through a Page arrow in the upper left of a dialog.
You may specify your own arrangement of controls in a dialog through use of the LAYOUT command to specify columns, positioning of control labels, and justifications, the CHAPTER command to create tabs, and the GROUP command to create groups of property controls. In addition, you can specify the exact placement of each control and label for any given page of a dialog using positioning controls (see Positioning controls and labels).
