Panel functions allow the use of stacked windows and ensure the proper portions of each window and the curses <STRONG>stdscr</STRONG> window are hidden or displayed when panels are added, moved, modified or removed. The set of cur- rently visible panels is the stack of panels. The <STRONG>stdscr</STRONG> window is beneath all panels, and is not considered part of the stack. A window is associated with every panel. The panel rou- tines 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 <STRONG><A HREF="ncurses.3x.html">curses(3x)</A></STRONG>, make only high-level curses calls, and work anywhere ter- minfo curses does.</PRE><H2>FUNCTIONS</H2><PRE> <STRONG>new_panel(win)</STRONG> allocates a <STRONG>PANEL</STRONG> structure, associates it with <STRONG>win</STRONG>, places the panel on the top of the stack (causes it to be displayed above any other panel) and returns a pointer to the new panel. <STRONG>void</STRONG> <STRONG>update_panels()</STRONG> refreshes the virtual screen to reflect the rela- tions between the panels in the stack, but does not call doupdate() to refresh the physical screen. Use this function and not wrefresh or wnoutrefresh. update_panels() may be called more than once before a call to doupdate(), but doupdate() is the func- tion responsible for updating the physical screen. <STRONG>del_panel(pan)</STRONG> removes the given panel from the stack and deallo- cates the <STRONG>PANEL</STRONG> structure (but not its associated window). <STRONG>hide_panel(pan)</STRONG> removes the given panel from the panel stack and thus hides it from view. The <STRONG>PANEL</STRONG> structure is not lost, merely removed from the stack. <STRONG>show_panel(pan)</STRONG> makes a hidden panel visible by placing it on top of the panels in the panel stack. See COMPATIBILITY below. <STRONG>top_panel(pan)</STRONG> puts the given visible panel on top of all panels in the stack. See COMPATIBILITY below. <STRONG>bottom_panel(pan)</STRONG> puts panel at the bottom of all panels. <STRONG>move_panel(pan,starty,startx)</STRONG> moves the given panel window so that its upper-left corner is at <STRONG>starty</STRONG>, <STRONG>startx</STRONG>. It does not change the position of the panel in the stack. Be sure to use this function, not <STRONG>mvwin()</STRONG>, to move a panel window. <STRONG>replace_panel(pan,window)</STRONG> replaces the current window of panel with <STRONG>window</STRONG> (useful, for example if you want to resize a panel; if you're using <STRONG>ncurses</STRONG>, you can call <STRONG>replace_panel</STRONG> on the output of <STRONG><A HREF="wresize.3x.html">wresize(3x)</A></STRONG>). It does not change the position of the panel in the stack. <STRONG>panel_above(pan)</STRONG> returns a pointer to the panel above pan. If the panel argument is <STRONG>(PANEL</STRONG> <STRONG>*)0</STRONG>, it returns a pointer to the bottom panel in the stack. <STRONG>panel_below(pan)</STRONG> returns a pointer to the panel just below pan. If the panel argument is <STRONG>(PANEL</STRONG> <STRONG>*)0</STRONG>, it returns a pointer to the top panel in the stack. <STRONG>set_panel_userptr(pan,ptr)</STRONG> sets the panel's user pointer. <STRONG>panel_userptr(pan)</STRONG> returns the user pointer for a given panel. <STRONG>panel_window(pan)</STRONG> returns a pointer to the window of the given panel.</PRE><H2>DIAGNOSTICS</H2><PRE> Each routine that returns a pointer returns <STRONG>NULL</STRONG> if an error occurs. Each routine that returns an int value returns <STRONG>OK</STRONG> if it executes successfully and <STRONG>ERR</STRONG> if not.</PRE><H2>COMPATIBILITY</H2><PRE> 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 program- ming interface is unchanged). The <STRONG>PANEL</STRONG> data structures are merely similar. The programmer is cautioned not to directly use <STRONG>PANEL</STRONG> fields. The functions <STRONG>show_panel()</STRONG> and <STRONG>top_panel()</STRONG> are identical in this implementation, and work equally well with dis- played or hidden panels. In the native System V implemen- tation, <STRONG>show_panel()</STRONG> is intended for making a hidden panel visible (at the top of the stack) and <STRONG>top_panel()</STRONG> 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.</PRE><H2>NOTE</H2><PRE> In your library list, libpanel.a should be before libn- curses.a; that is, you want to say `-lpanel -lncurses', not the other way around (which would give you a link error using GNU <STRONG><A HREF="ld.1.html">ld(1)</A></STRONG> and some other linkers).</PRE><H2>FILES</H2><PRE> panel.h interface for the panels library libpanel.a the panels library itself</PRE><H2>SEE ALSO</H2><PRE> <STRONG><A HREF="ncurses.3x.html">curses(3x)</A></STRONG></PRE><H2>AUTHOR</H2><PRE> Originally written by Warren Tucker <wht@n4hgf.mt- park.ga.us>, primarily to assist in porting u386mon to systems without a native panels library.
