A secondary window works the same as a window in a standard Windows application. It includes a caption bar identifying the window contents and has window borders that separate it from the main Viewer window. Users can minimize, maximize, or move secondary windows or use scroll bars to view different parts of the topic displayed in a window.
You can display any Viewer topic in a secondary window, so a secondary window can include virtually any standard Viewer feature, including jumps, links to popup windows, nonscrolling areas, bitmaps, audio segments, or animation sequences. The only limitations on the use of secondary windows are as follows:
Viewer can display only one secondary window at a time. If the user tries to display a secondary window while Viewer is already displaying one, the new window replaces the current one.
You cannot use some Viewer commands in secondary windows. These commands are listed in Chapter 18, “Multimedia Viewer Commands.”
Secondary windows remain open if the user uses the system menu to close the main Viewer window. The user must then close the secondary window using the system menu in the upper-left corner of the window.
