The secondary window manager provides all the capability of a standard dialog window, but it permits the window to be sizable and automatically formats the window and manages the scroll bars.

The functions that manipulate and control the secondary window are designed to convert easily from the standard dialog manager.

This section describes the secondary window functions and data structures.
