Panels are curses(3) windows with the added feature of depth. Panel functions allow the use of stacked windows and ensure the proper portions of each window and the curses stdscr window are hidden or displayed when panels are added, moved, modified or removed. The set of currently visible panels is the stack of panels. The stdscr window is beneath all panels, and is not considered part of the stack.
A window is associated with every panel. The panel routines enable you to create, move, hide, and show panels, as well as position a panel at any desired location in the stack.
Panel routines are a functional layer added to curses(3), make only high-level curses calls, and work anywhere terminfo curses does.
Each routine that returns a pointer returns NULL if an error occurs. Each routine that returns an int value returns OK if it executes successfully and ERR if not.
Reasonable care has been taken to ensure compatibility with the native panel facility introduced in SVr3.2 (inspection of the SVr4 manual pages suggests the programming interface is unchanged). The PANEL data structures are merely similar. The programmer is cautioned not to directly use PANEL fields.
The functions show_panel() and top_panel() are identical in this implementation, and work equally well with displayed or hidden panels. In the native System V implementation, show_panel() is intended for making a hidden panel visible (at the top of the stack) and top_panel() is intended for making an already-visible panel move to the top of the stack. You are cautioned to use the correct function to ensure compatibility with native panel libraries.
In your library list, libpanel.a should be before libncurses.a; that is, you want to say `-lpanel -lncurses', not the other way around (which would usually give a link-error).
