Rectangles

Rectangles are the simplest organizer objects. Their role is entirely visual. Rectangles can be nested within Frames and can be placed within or partly within (overlapping) other Rectangles. You can place SmartObjects on a Rectangle as long as there is an appropriate Smart organizer (SmartWindow, SmartDialog, or SmartFrame) to support them.

By default, a Rectangle appears as a figure with a closed, sunken border 2 pixels thick:

By combining a Text widget with a Rectangle, you can create an object similar in appearance to an MS-Windows Frame widget:

There is no line object in the 4GL, but by carefully sizing, positioning, and coloring one or two Rectangles, you can create the illusion of a line object. This can be convenient as a visual spacer.
