7 DUIM-Layouts Library

7.1 Overview

The DUIM-Layouts library contains interfaces that define a number of layouts for use in your GUI applications, as well as the necessary functions, generic functions, and macros for creating, manipulating, and calculating them automatically. The library contains a single module, duim-layouts, from which all the interfaces described in this chapter are exposed. Section 7.3 on page 453 contains complete reference entries for each exposed interface.

Layouts are sheet objects that determine how the interface elements are presented on the screen. A layout object takes a number of children, expressed as a vector, and lays out those children according to certain constraints. Each child of a layout must be an instance of a DUIM class.
