  78        Panels  are  <STRONG><A HREF="ncurses.3x.html">curses(3x)</A></STRONG>  windows with the added feature of
  79        depth.  Panel functions allow the use of  stacked  windows
  80        and  ensure  the  proper  portions  of each window and the
  81        curses <STRONG>stdscr</STRONG> window are hidden or displayed  when  panels
  82        are  added,  moved,  modified or removed.  The set of cur-
  83        rently visible panels is the stack of panels.  The  <STRONG>stdscr</STRONG>
  84        window  is  beneath all panels, and is not considered part
  85        of the stack.
  86
  87        A window is associated with every panel.  The  panel  rou-
  88        tines  enable  you to create, move, hide, and show panels,
  89        as well as position a panel at any desired location in the
  90        stack.
  91
  92        Panel routines are a functional layer added to <STRONG><A HREF="ncurses.3x.html">curses(3x)</A></STRONG>,
  93        make only high-level curses calls, and work anywhere  ter-
  94        minfo curses does.

  97 </PRE>
  98 <H2><a name="h2-FUNCTIONS">FUNCTIONS</a></H2><PRE>
  99        <STRONG>new_panel(win)</STRONG>
 100               allocates   a   <STRONG>PANEL</STRONG> structure, associates it with
 101               <STRONG>win</STRONG>, places the panel  on  the  top  of  the  stack
 102               (causes   it  to   be   displayed  above  any other
 103               panel) and returns a pointer to the new panel.
 104
 105        <STRONG>update_panels()</STRONG>
 106               refreshes the virtual screen to reflect  the  rela-
 107               tions between the panels in the stack, but does not
 108               call doupdate() to  refresh  the  physical  screen.
 109               Use this function and not <STRONG>wrefresh</STRONG> or <STRONG>wnoutrefresh</STRONG>.
 110               <STRONG>update_panels</STRONG> may be called more than once before a
 111               call  to doupdate(), but doupdate() is the function
 112               responsible for updating the physical screen.
 113
 114        <STRONG>del_panel(pan)</STRONG>
 115               removes the given panel from the  stack and deallo-
 116               cates  the  <STRONG>PANEL</STRONG> structure (but not its associated
 117               window).
 118
 119        <STRONG>hide_panel(pan)</STRONG>
 120               removes the given panel from the  panel  stack  and
 121               thus hides it from view. The <STRONG>PANEL</STRONG> structure is not
 122               lost, merely removed from the stack.
 123
 124        <STRONG>panel_hidden(pan)</STRONG>
 125               returns <STRONG>TRUE</STRONG> if the panel is in  the  panel  stack,
 126               <STRONG>FALSE</STRONG>  if  it  is  not.   If  the  panel  is a null
 127               pointer, return ERR.
 128
 129        <STRONG>show_panel(pan)</STRONG>
 130               makes a hidden panel visible by placing it  on  top
 131               of the panels in the panel stack. See COMPATIBILITY
 132               below.
 133
 134        <STRONG>top_panel(pan)</STRONG>
 135               puts the given visible panel on top of  all  panels
 136               in the stack.  See COMPATIBILITY below.
 137
 138        <STRONG>bottom_panel(pan)</STRONG>
 139               puts panel at the bottom of all panels.
 140
 141        <STRONG>move_panel(pan,starty,startx)</STRONG>
 142               moves the given panel window so that its upper-left
 143               corner is at <STRONG>starty</STRONG>, <STRONG>startx</STRONG>.  It  does  not  change
 144               the position of the panel in the stack.  Be sure to
 145               use this function, not <STRONG>mvwin()</STRONG>,  to  move  a  panel
 146               window.
 147
 148        <STRONG>replace_panel(pan,window)</STRONG>
 149               replaces  the  current  window of panel with <STRONG>window</STRONG>
 150               (useful, for example if you want to resize a panel;
 151               if you're using <STRONG>ncurses</STRONG>, you can call <STRONG>replace_panel</STRONG>
 152               on the output of <STRONG><A HREF="wresize.3x.html">wresize(3x)</A></STRONG>).  It does not  change
 153               the position of the panel in the stack.
 154
 155        <STRONG>panel_above(pan)</STRONG>
 156               returns  a  pointer to the panel above pan.  If the
 157               panel argument is <STRONG>(PANEL</STRONG> <STRONG>*)0</STRONG>, it returns a  pointer
 158               to the bottom panel in the stack.
 159
 160        <STRONG>panel_below(pan)</STRONG>
 161               returns  a pointer to the panel just below pan.  If
 162               the panel argument is  <STRONG>(PANEL</STRONG>  <STRONG>*)0</STRONG>,  it  returns  a
 163               pointer to the top panel in the stack.
 164
 165        <STRONG>set_panel_userptr(pan,ptr)</STRONG>
 166               sets the panel's user pointer.
 167
 168        <STRONG>panel_userptr(pan)</STRONG>
 169               returns the user pointer for a given panel.
 170
 171        <STRONG>panel_window(pan)</STRONG>
 172               returns a pointer to the window of the given panel.

 177        Each  routine  that  returns  a pointer returns <STRONG>NULL</STRONG> if an
 178        error occurs. Each  routine  that  returns  an  int  value
 179        returns <STRONG>OK</STRONG> if it executes successfully and <STRONG>ERR</STRONG> if not.

 183 <H2><a name="h2-COMPATIBILITY">COMPATIBILITY</a></H2><PRE>
 184        Reasonable  care  has been taken to  ensure  compatibility
 185        with  the  native  panel  facility  introduced  in  SVr3.2
 186        (inspection of the SVr4 manual pages suggests the program-
 187        ming interface is unchanged).  The <STRONG>PANEL</STRONG>  data  structures
 188        are  merely   similar. The  programmer is cautioned not to
 189        directly use <STRONG>PANEL</STRONG> fields.
 190
 191        The functions <STRONG>show_panel()</STRONG> and <STRONG>top_panel()</STRONG>  are  identical
 192        in  this  implementation,  and work equally well with dis-
 193        played or hidden panels.  In the native System V implemen-
 194        tation, <STRONG>show_panel()</STRONG> is intended for making a hidden panel
 195        visible (at the top  of  the  stack)  and  <STRONG>top_panel()</STRONG>  is
 196        intended  for  making an already-visible panel move to the
 197        top of the stack. You are cautioned  to  use  the  correct
 198        function   to   ensure  compatibility  with  native  panel
 199        libraries.

 204        In your library list, libpanel.a should  be  before  libn-
 205        curses.a;  that  is,  you want to say `-lpanel -lncurses',
 206        not the other way around (which would usually give a link-
 207        error).
